A 1099 is a tax form reporting income outside of traditional employment — freelance earnings, contractor payments, investment income, retirement distributions, and more. Common versions: 1099-NEC (freelance), 1099-DIV (dividends), 1099-INT (interest), 1099-R (retirement), 1099-B (brokerage sales). No employer withholds taxes on 1099 income.
A 401(k) is a tax-advantaged retirement savings account offered by employers. Contributions are made pre-tax, reducing your taxable income today, while withdrawals in retirement are taxed as ordinary income. Employers often match a percentage of contributions, making it one of the most valuable employee benefits. The IRS sets annual contribution limits ($23,000 in 2024 for those under 50).
A 403(b) is similar to a 401(k) but available to employees of public schools, non-profits, and certain tax-exempt organizations. It offers the same pre-tax contribution benefits and similar annual limits. Some 403(b) plans offer unique catch-up contribution provisions for long-tenured employees.
The 50/30/20 rule allocates after-tax income as: 50% to needs (rent, utilities, groceries, minimum debt payments), 30% to wants (dining out, entertainment, subscriptions), and 20% to savings and debt payoff. It's a simple starting framework, though high cost-of-living areas often require adjusting the needs percentage upward.
ACH is the electronic network processing US bank-to-bank transfers, including direct deposits, bill payments, and P2P transfers. ACH transfers are typically free but take 1–3 business days to settle. Same-day ACH is available for an additional fee. Most payroll, Social Security, and tax refund deposits use ACH.
AGI is your gross income minus specific above-the-line deductions including student loan interest, IRA contributions, alimony paid (pre-2019), and HSA contributions. AGI is used to calculate eligibility for credits, deductions, and phase-outs. Many tax benefits phase out as AGI rises.
A home appraisal is a licensed professional's assessment of a property's fair market value, required by lenders before approving a mortgage. If the appraisal comes in lower than the purchase price, the lender won't finance the full amount — requiring renegotiation, additional down payment, or deal cancellation.
APR is the annual cost of borrowing expressed as a percentage, including interest and fees. Credit card APRs range widely (15–30%+). Unlike APY (which measures earnings), APR measures what you pay. Paying your balance in full each month avoids interest charges entirely.
APY reflects the real return on a savings account or CD including compound interest. Unlike APR, APY accounts for how often interest compounds. A 5% APR compounding monthly equals approximately 5.12% APY. When comparing savings accounts, always use APY for an accurate comparison.
A balance transfer moves high-interest credit card debt to a new card offering a 0% introductory APR (typically 12–21 months). Transfer fees are usually 3–5% of the balance. Strategic balance transfers can save hundreds in interest while paying down principal. Avoid new spending on the card during the intro period.
Beta measures a stock's price movement relative to the market. A beta of 1.0 moves in line with the market; above 1.0 is more volatile; below 1.0 is less volatile. High-beta stocks amplify gains in bull markets but fall harder in downturns. Low-beta stocks suit conservative investors seeking stability.
Bitcoin is the first decentralized cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. With a fixed supply of 21 million coins, it is often called 'digital gold' and is treated as a store of value. Bitcoin operates on a Proof of Work blockchain and is the most widely held and recognized cryptocurrency globally.
A buyback occurs when a company purchases its own shares from the market, reducing shares outstanding. This increases EPS and can boost stock price. Buybacks returned over $1 trillion to US shareholders in 2022. Critics argue buybacks prioritize short-term price over long-term investment; a 1% excise tax was added in 2023.
A call option gives the holder the right to buy a stock at the strike price before expiration. Call buyers profit when the stock rises above the strike plus premium paid. Sellers (writers) collect the premium and are obligated to sell if the option is exercised. Covered calls involve owning the underlying stock.
Capital gains are profits from selling investments for more than you paid. Short-term gains (assets held under 1 year) are taxed as ordinary income. Long-term gains (assets held over 1 year) are taxed at 0%, 15%, or 20% depending on income. Tax-loss harvesting can offset capital gains.
Catch-up contributions allow individuals aged 50 and older to contribute more than the standard IRS limit to retirement accounts. For 2024, the catch-up limit is an additional $7,500 for 401(k)s and $1,000 for IRAs. This provision helps those who started saving late to accelerate retirement readiness.
A CD is a time deposit with a fixed interest rate held for a specified term (3 months to 5 years). CDs offer higher rates than savings accounts in exchange for keeping funds locked until maturity. Early withdrawal incurs a penalty. FDIC-insured CDs are among the safest savings vehicles available.
A charge-off occurs when a creditor declares a debt unlikely to be collected — typically after 180 days of non-payment. The debt is removed from the creditor's books as an asset, but you still legally owe it. Charge-offs are reported to credit bureaus for 7 years and severely damage credit scores.
Closing costs are fees paid at the closing of a real estate transaction, typically 2–5% of the loan amount. They include loan origination fees, appraisal, title insurance, attorney fees, and prepaid interest. Some costs are negotiable; others are fixed. First-time buyers often roll closing costs into the loan.
Coinsurance is the percentage of costs you pay after meeting your deductible. With 80/20 coinsurance, your insurer pays 80% and you pay 20% until reaching your out-of-pocket maximum. After the OOP max, insurance covers 100% of covered expenses for the rest of the plan year.
A cold wallet (hardware wallet) stores private keys offline, completely disconnected from the internet. Devices like Ledger and Trezor protect crypto from online hacks. Cold storage is the most secure method for long-term crypto holdings. 'Not your keys, not your coins' — keeping crypto on exchanges means trusting a third party with custody.
Compound interest means you earn returns not just on your principal but on previously accumulated interest. $10,000 invested at 8% annually becomes $21,589 in 10 years and $46,610 in 20 years — without adding a single dollar. The longer the time horizon, the more powerful compounding becomes. Starting early is the single biggest advantage in wealth-building.
A copay is a fixed dollar amount you pay for specific healthcare services — typically $20–$50 for a primary care visit or prescription. Copays apply even after you meet your deductible. They are separate from deductibles and coinsurance and are due at the time of service.
CPI measures the average change in prices paid by US consumers for a basket of goods and services. Published monthly by the Bureau of Labor Statistics, it's the primary inflation gauge. Core CPI excludes volatile food and energy. The Fed targets 2% annual inflation. CPI directly affects Social Security benefit adjustments (COLA).
Credit utilization is the ratio of credit card balances to credit limits. Using $1,500 of a $5,000 limit = 30% utilization. Keeping utilization below 30% helps your credit score; below 10% is even better. High utilization signals credit stress. Utilization resets each month when issuers report to credit bureaus.
DTI measures monthly debt payments divided by gross monthly income. Lenders use DTI to assess mortgage, auto loan, and personal loan eligibility. A DTI below 36% is considered healthy; most mortgage lenders cap qualifying DTI at 43%. A high DTI signals over-leveraging and limits borrowing options.
The deductible is the amount you pay out-of-pocket before your insurance starts covering costs. For health insurance, if your deductible is $2,000, you pay the first $2,000 of medical expenses each year before insurance kicks in. Higher deductibles = lower premiums. Lower deductibles = higher premiums.
DeFi refers to blockchain-based financial services — lending, borrowing, trading, and earning yield — without traditional intermediaries like banks. Smart contracts automate transactions. Total Value Locked (TVL) measures DeFi's size. While DeFi offers high yields, it carries smart contract risk, protocol exploits, and regulatory uncertainty.
Diversification reduces risk by spreading investments across multiple assets, sectors, and geographies. When one investment performs poorly, others may compensate. Modern Portfolio Theory shows that a well-diversified portfolio can achieve a given return with less risk than holding individual securities.
A dividend is a portion of a company's profits paid to shareholders, usually quarterly. Dividend-paying stocks provide regular income and tend to be less volatile. The dividend yield represents annual dividends as a percentage of share price. Dividend reinvestment (DRIP) compounds wealth over time by automatically purchasing additional shares.
DCA involves investing a fixed dollar amount at regular intervals regardless of price. When prices are high, you buy fewer shares; when low, you buy more. This removes emotional decision-making and reduces timing risk. DCA is the underlying principle behind regular 401(k) contributions.
The down payment is the percentage of the home price paid upfront in cash. The standard is 20%, which avoids PMI and qualifies for better rates. Many programs allow 3–5% down (FHA: 3.5% with 580+ credit score, Conventional 97: 3%). Lower down payments increase monthly payments and total interest paid.
EBITDA measures operating profitability before capital structure, tax strategy, and accounting adjustments. It's widely used for valuation multiples (EV/EBITDA) and comparing companies across industries. However, EBITDA excludes CapEx and can be manipulated — Warren Buffett famously criticized its overuse as a metric.
An emergency fund is liquid savings covering 3–6 months of essential expenses for unexpected events — job loss, medical bills, car repairs. Keep it in an FDIC-insured HYSA for accessibility and yield. Without an emergency fund, people rely on high-interest credit cards or liquidate investments at the wrong time.
EPS is a company's net profit divided by outstanding shares. It's used in P/E ratio calculations and reflects per-share profitability. Diluted EPS accounts for convertible securities and stock options. Companies often manage EPS through buybacks (reducing share count) and accounting choices.
An ETF is a basket of securities — stocks, bonds, or commodities — that trades on a stock exchange throughout the day like a stock. ETFs offer instant diversification, low expense ratios, and tax efficiency. Most ETFs track an index (e.g., S&P 500), making them a core tool for passive investing strategies.
Ethereum is the leading programmable blockchain platform that enables smart contracts and decentralized applications (dApps). Its native currency, Ether (ETH), is used to pay transaction fees (gas). Ethereum transitioned from Proof of Work to Proof of Stake in 2022 (The Merge), reducing energy use by ~99.95%.
The expense ratio is the annual percentage of fund assets charged for management, administration, and operations. A 0.03% expense ratio means $3 per year on every $10,000 invested. Index ETFs like VOO often have ratios below 0.05%, while actively managed funds typically charge 0.5–1.5%. Over decades, the difference compounds significantly.
The FDIC is a US government agency that insures bank deposits up to $250,000 per depositor, per institution, per account category. Created after the Great Depression, FDIC insurance ensures you won't lose money if a bank fails. Credit unions offer similar protection through NCUA.
The federal funds rate is the interest rate at which banks lend to each other overnight. The Fed raises it to fight inflation (making borrowing more expensive) and cuts it during slowdowns (stimulating economic activity). It influences mortgage rates, credit card APRs, and savings account yields across the economy.
The Federal Reserve is the US central bank, operating through 12 regional banks and the Board of Governors. Its dual mandate: maximum employment and stable prices (2% inflation target). The Fed sets the federal funds rate and uses tools like open market operations and quantitative easing (QE) or tightening (QT) to manage the economy.
A FICO score is the most widely used credit score in the US, ranging from 300 to 850. Lenders use it to evaluate creditworthiness and set interest rates. Scores above 750 qualify for the best rates; 670–749 is good; 580–669 is fair; below 580 is poor. Payment history (35%) and credit utilization (30%) are the biggest factors.
Financial Independence means having enough savings and investments to cover living expenses indefinitely without active work. The FIRE (Financial Independence, Retire Early) movement uses the 4% rule — if you can live on 4% of your portfolio annually, you're financially independent. Achieving FI typically requires 25× your annual expenses invested in diversified assets.
FCF is cash generated after capital expenditures — what's actually available for dividends, buybacks, debt repayment, or acquisitions. FCF = Operating Cash Flow − CapEx. Unlike reported earnings, FCF is harder to manipulate and is often considered the most important indicator of financial health by value investors.
An FSA is an employer-offered account allowing pre-tax dollars for qualifying medical expenses. Unlike HSAs, FSAs are 'use it or lose it' — unspent funds expire at year-end (employers may allow up to $640 rollover). FSAs can be used for copays, prescriptions, dental, vision, and many other medical costs.
GDP is the total dollar value of all goods and services produced in the US within a year. It's measured quarterly by the Bureau of Economic Analysis. Two consecutive quarters of negative GDP growth constitute a technical recession. The US GDP is approximately $27 trillion, the largest in the world.
A HELOC is a revolving line of credit secured by home equity. Like a credit card, you borrow as needed up to a limit during the draw period (typically 10 years). You only pay interest on what you borrow. After the draw period, you repay principal plus interest. HELOCs typically have variable rates.
An HMO requires choosing a primary care physician (PCP) who coordinates your care and provides referrals to specialists. You must use in-network providers except in emergencies. HMOs typically have lower premiums and copays but less flexibility than PPOs. Common for employer-sponsored plans.
Home equity is the difference between your home's current market value and what you still owe on your mortgage. As you pay down your mortgage and/or the home appreciates, equity grows. Equity can be accessed through a HELOC or cash-out refinance for major expenses like renovations or education.
An HSA is a triple-tax-advantaged account for those with a High-Deductible Health Plan (HDHP): contributions are pre-tax, growth is tax-free, and qualified medical withdrawals are tax-free. Unused funds roll over indefinitely. After age 65, HSA funds can be withdrawn for any purpose (taxed like a Traditional IRA). 2024 limits: $4,150 individual, $8,300 family.
A High-Yield Savings Account is an FDIC-insured savings account offering significantly higher interest rates than traditional bank savings accounts, typically 10–20× higher. Most HYSAs are offered by online banks with lower overhead. They are ideal for emergency funds and short-term savings goals.
An index fund tracks a market index like the S&P 500 or Total Stock Market. Instead of trying to beat the market, it mirrors its performance at low cost. Index funds consistently outperform most actively managed funds over long periods, making them the preferred choice for long-term investors following a buy-and-hold strategy.
Inflation is the rate at which prices rise over time, eroding purchasing power. At 3% annual inflation, $100 today buys what $74 will in 10 years. The Fed targets 2% inflation as a sign of healthy economic growth. Keeping savings in cash during high inflation means losing real value; investing is essential to outpace inflation.
An IPO is the first time a private company sells shares to the public, transitioning to a publicly traded company. Investment banks underwrite and price the offering. IPOs can generate significant returns but also come with lock-up periods, volatility, and limited financial history. SPACs became an alternative IPO route in 2020–21.
Itemizing deductions means listing eligible expenses — mortgage interest, state/local taxes (SALT, capped at $10,000), charitable donations, and medical expenses exceeding 7.5% of AGI — to reduce taxable income. Itemizing is only beneficial when total deductions exceed the standard deduction.
Implied volatility reflects the market's expectation of future price swings in an underlying asset, derived from option prices. High IV = expensive options (more uncertainty); low IV = cheaper options. The VIX measures implied volatility of S&P 500 options and is often called the 'fear gauge' of the market.
MAGI is your AGI plus certain deductions added back in. It's used to determine eligibility for Roth IRA contributions, the premium tax credit, IRA deductibility, and other benefits. MAGI thresholds vary by benefit — for 2024, Roth IRA contributions phase out above $146,000 for single filers.
Market cap is the total market value of a company's outstanding shares (share price × total shares). Large-cap stocks (>$10B) are established and stable; mid-cap ($2B–$10B) offer growth potential; small-cap (<$2B) are higher-risk, higher-reward. Index funds often weight holdings by market cap.
A mortgage is a loan secured by real estate, repaid over 15 or 30 years through monthly payments covering principal and interest. The home serves as collateral — failure to repay can result in foreclosure. Fixed-rate mortgages lock your rate for the loan term. ARM (adjustable-rate) mortgages offer lower initial rates that adjust periodically.
Net worth is everything you own (checking accounts, investments, real estate, vehicles) minus everything you owe (mortgage, student loans, credit cards, auto loans). Tracking net worth monthly or annually provides the clearest picture of financial progress. Growing net worth, not just income, is the true measure of financial health.
NFTs are blockchain-based certificates of ownership for unique digital assets — art, music, game items, and collectibles. Unlike fungible tokens (1 BTC = 1 BTC), each NFT is distinct. NFTs saw massive speculation in 2021–22 before a significant market correction. Use cases in gaming and digital ownership continue to evolve.
The out-of-pocket maximum is the most you'll pay for covered healthcare services in a plan year. Once reached, your insurer covers 100% of remaining covered costs. The ACA caps OOP maximums at $9,450 for individuals and $18,900 for families in 2024 for marketplace plans.
An options contract gives the buyer the right, but not the obligation, to buy (call) or sell (put) an asset at a specified price (strike) before expiration. Buyers pay a premium to the seller. Options are used for hedging, income generation (covered calls), and speculation. The Chicago Board Options Exchange (CBOE) is the primary US options market.
Overdraft occurs when a transaction exceeds your available bank balance. Banks may cover the amount for a fee ($25–$35 per item) or link to savings for automatic transfers. Many banks now offer overdraft protection programs or 'no fee' overdraft products. Frequent overdrafts signal cash flow issues.
The P/E ratio compares a stock's price to its earnings per share. A P/E of 20 means investors pay $20 for every $1 of annual earnings. High P/E may indicate growth expectations or overvaluation; low P/E may signal undervaluation or weak prospects. Compare within the same sector for meaningful analysis.
A pension is a defined benefit plan where an employer promises a specific monthly retirement payment based on salary history and years of service. Unlike 401(k)s, the investment risk is borne by the employer. Pensions are becoming rare in private sector jobs but remain common in government and union employment.
PMI is insurance required by lenders when your down payment is less than 20% of the home's value. It protects the lender — not you — if you default. PMI costs 0.5–1.5% of the loan amount annually. Once your equity reaches 20%, you can request removal. FHA loans require mortgage insurance regardless of equity.
A PPO gives you more flexibility to see any doctor or specialist without a referral, in-network or out-of-network. Out-of-network care is covered at a lower rate. PPOs have higher premiums than HMOs but are preferred by those with ongoing specialist needs or who frequently travel.
The premium is the amount you pay for insurance coverage, typically monthly or annually. Premiums are determined by risk factors like age, health, driving record, and coverage level. Higher premiums usually come with lower out-of-pocket costs; lower premiums mean you pay more when you make a claim.
A put option gives the holder the right to sell a stock at the strike price before expiration. Put buyers profit when the stock falls below the strike minus premium paid. Puts are commonly used to hedge long stock positions against downside risk. Protective puts function like portfolio insurance.
Quantitative Easing is a monetary policy where the Fed purchases government bonds and mortgage-backed securities to inject money into the financial system, lowering long-term interest rates and encouraging lending. The Fed used QE during the 2008 financial crisis and COVID-19 pandemic, expanding its balance sheet to ~$9 trillion by 2022.
Rebalancing restores your portfolio to its target asset allocation by selling assets that have grown above their target weight and buying those that have fallen below. Without rebalancing, a stock market rally could leave you overexposed to equities. Most advisors recommend rebalancing annually or when allocations drift more than 5%.
The RMD is the minimum amount the IRS requires you to withdraw annually from tax-deferred retirement accounts (Traditional IRA, 401(k)) starting at age 73. RMDs are calculated based on your account balance and IRS life expectancy tables. Failure to take RMDs results in a 25% excise tax on the amount not withdrawn.
A Roth conversion involves moving funds from a Traditional IRA or 401(k) into a Roth IRA. You pay income tax on the converted amount in the year of conversion, but future growth and qualified withdrawals become tax-free. It's often a smart strategy in low-income years or before anticipated tax rate increases.
A Roth IRA is a personal retirement account funded with after-tax dollars. Since you pay taxes now, qualified withdrawals in retirement are completely tax-free — including investment gains. Roth IRAs have income limits for eligibility and contribution limits ($7,000 in 2024 for those under 50). They are ideal for those who expect to be in a higher tax bracket in retirement.
The S&P 500 is a stock market index tracking the 500 largest publicly traded US companies by market capitalization. It is the most widely used benchmark for US equity performance and is often used as a proxy for 'the market.' Major ETFs like SPY and VOO track this index at minimal cost.
A secured credit card requires a cash deposit (typically $200–$500) that becomes your credit limit. It functions like a regular credit card and reports to credit bureaus, making it an effective tool for building or rebuilding credit history. After 12–18 months of responsible use, many issuers upgrade you to an unsecured card.
Social Security is a federal program providing retirement, disability, and survivor benefits. Workers earn credits through payroll taxes (FICA), and retirement benefits are calculated based on your highest 35 earning years. Full retirement age is 67 for those born in 1960 or later, though benefits can begin as early as 62 (at a reduced amount) or be delayed until 70 for a higher monthly payout.
Stablecoins are crypto assets pegged to a stable asset, typically the US dollar (USDT, USDC, DAI). They maintain price stability while preserving crypto's speed and programmability. Used in DeFi for lending, trading, and yield generation. Regulatory scrutiny of stablecoins has increased significantly in the US.
The standard deduction reduces your taxable income by a flat amount set by the IRS ($14,600 for single filers in 2024, $29,200 for married filing jointly). Most taxpayers benefit more from the standard deduction than itemizing. It makes tax filing simpler and eliminates the need to track individual deductible expenses.
The strike price is the fixed price at which an option can be exercised. Call options are profitable when the underlying price exceeds the strike (in-the-money). Put options are profitable when the underlying price falls below the strike. At-the-money options have a strike price equal to the current market price.
The US uses a progressive tax system with brackets at 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Each bracket applies only to income within that range — not your entire income. Only dollars above each threshold are taxed at the higher rate, so moving into a higher bracket doesn't mean you pay that rate on everything.
A tax credit directly reduces your tax bill dollar-for-dollar, making it more valuable than a deduction. Examples include the Child Tax Credit ($2,000/child), Earned Income Tax Credit (EITC), American Opportunity Credit (education), and Saver's Credit (retirement contributions). Refundable credits can result in a refund even if you owe no taxes.
Term life insurance provides death benefit coverage for a specified period (10, 20, or 30 years). It is the most affordable form of life insurance and is ideal for income replacement during years when dependents rely on you financially. If you die during the term, beneficiaries receive the death benefit tax-free.
Theta measures how much an option's value decreases with each passing day, all else equal. Options lose value as expiration approaches because there's less time for profitable movement. Theta benefits option sellers and hurts buyers. ATM options near expiration experience the fastest time decay.
A Traditional IRA allows contributions that may be tax-deductible depending on your income and whether you have workplace retirement coverage. Investments grow tax-deferred, and withdrawals in retirement are taxed as ordinary income. Required Minimum Distributions (RMDs) begin at age 73.
Vesting refers to the schedule by which an employee gains full ownership of employer contributions to a retirement plan. Immediate vesting means you own 100% from day one. Cliff vesting means full ownership after a set period. Graded vesting gradually increases ownership over time. Your own contributions are always 100% vested.
A W-2 is the tax form your employer sends by January 31 reporting your annual wages and the amount withheld for federal, state, and local taxes, Social Security, and Medicare. You use W-2 information to complete your tax return. Multiple employers mean multiple W-2s.
WACC is the blended cost of a company's debt and equity financing, weighted by their proportions. It serves as the discount rate in DCF valuation models. A company creates value when return on invested capital (ROIC) exceeds WACC. Lower WACC increases valuation; higher WACC reflects greater risk.
Whole life insurance provides lifelong coverage and builds cash value over time. Premiums are significantly higher than term life but remain level for life. The cash value grows at a guaranteed rate and can be borrowed against. It is more suitable as an estate planning tool than pure income replacement.
A wire transfer moves funds directly between bank accounts in real time. Domestic wires typically cost $15–$35 and settle the same day. International wires (via SWIFT) may take 1–5 business days and cost more. Wires are commonly used for large transactions like real estate closings.
The yield curve plots interest rates of US Treasury bonds across maturities (3 months to 30 years). A normal curve slopes upward — longer maturities offer higher rates. An inverted yield curve (short rates > long rates) has preceded every US recession in the past 50 years. It reflects expectations about growth and Fed policy.
