A complete guide to how Fixed Deposits work in India — types, interest rates, premature withdrawal rules, and who should consider them.
Long before mutual funds or stocks became mainstream, the Fixed Deposit (FD) was — and still is — the default safe investment for most Indian families. Nearly every bank and post office offers one, and for good reason: it's simple, predictable, and backed by the safety of the banking system.
A Fixed Deposit is a savings instrument where you deposit a lump sum with a bank (or post office) for a fixed period, at a fixed interest rate, agreed upon at the time of booking. Unlike a savings account, you can't withdraw freely — the money is locked in for the chosen tenure, in exchange for a higher interest rate than a regular savings account offers.
When you open an FD, you choose two things: the amount you want to deposit, and the tenure (ranging from as short as 7 days to as long as 10 years, depending on the bank). The interest rate is locked in at the time of booking and doesn't change even if the bank later revises its rates for new deposits.
At maturity, you receive your original deposit back along with the accumulated interest — either as a lump sum, or paid out periodically during the tenure, depending on the type of FD you choose.
| Type | How It Works |
|---|---|
| Cumulative FD | Interest is compounded and paid out only at maturity, along with the principal |
| Non-Cumulative FD | Interest is paid out periodically — monthly, quarterly, or annually — rather than at maturity |
| Tax-Saving FD | A 5-year lock-in FD that qualifies for a deduction under Section 80C, but interest earned is still taxable |
| Senior Citizen FD | Offers a slightly higher interest rate (typically 0.25%-0.50% more) for depositors above 60 |
FD interest rates vary by bank, tenure, and depositor category (regular vs senior citizen), and are influenced by the broader interest rate environment set by the RBI. Generally, longer tenures don't always mean higher rates — some banks offer their best rates on medium tenures (like 1-3 years) rather than the longest ones, so it's worth comparing rates across tenures rather than assuming longer is always better.
Most banks allow you to break an FD before maturity, but this usually comes with a penalty — typically a reduction of 0.5%-1% in the interest rate you actually receive, applied retroactively for the period the money was held. Some tax-saving FDs, however, don't allow premature withdrawal at all during the 5-year lock-in, since they're specifically designed to enforce long-term saving.
A savings account typically offers a modest interest rate and full liquidity — you can withdraw anytime. An FD sacrifices that liquidity in exchange for a meaningfully higher interest rate, since the bank knows exactly how long it can use your money. For funds you're confident you won't need for a specific period, this trade-off usually works in your favor.
Rather than manually calculating maturity value, you can use our FD Calculator to instantly see how much your deposit will grow to, based on the amount, tenure, and interest rate you choose.
1. Not comparing rates across banks before booking. Small private and small finance banks often offer meaningfully higher FD rates than large public sector banks for the same tenure.
2. Choosing a single large FD instead of laddering. Locking all your money into one FD with one maturity date reduces flexibility — we'll cover laddering strategy later in this pillar.
3. Ignoring the tax impact of FD interest. FD interest is fully taxable at your income slab rate, and TDS is deducted if interest exceeds the threshold — this often surprises first-time depositors.
4. Assuming the tax-saving FD is a good tax-saving choice by default. While it offers a Section 80C deduction, the 5-year lock-in and fully taxable interest often make it less attractive than other 80C options like ELSS or PPF.
Key Takeaway: A Fixed Deposit trades liquidity for a fixed, predictable return, making it a foundational safe-investment tool for Indian savers. The next lesson covers FD vs RD: Which One Should You Choose?
Yes, the interest rate is locked in at the time of booking and doesn't change for the entire tenure, regardless of future rate movements.
Most FDs allow premature withdrawal, but usually with a penalty that reduces your effective interest rate. Some tax-saving FDs don't allow this at all during the lock-in.
Yes, FD interest is fully taxable at your income slab rate, and banks deduct TDS if the interest exceeds the applicable threshold in a financial year.
Yes, most banks offer an additional 0.25%-0.50% interest rate for depositors above 60 years of age.
Most banks allow FDs starting from as short as 7 days, though rates are typically less attractive at the very short end.
