A debt payoff calculator helps you create a realistic plan to become debt-free by showing you exactly how long it will take and how much interest you will pay in total. It compares different repayment strategies so you can choose the one that fits your financial situation.
Pay off your smallest balance first, regardless of interest rate. Once it is cleared, roll that payment into the next smallest debt.
Best for: People who need motivation from quick wins
Pay off your highest interest rate first to minimize total interest paid. Mathematically the most efficient method.
Best for: People focused on saving the most money
Even a small extra monthly payment can dramatically reduce your payoff time and total interest. Every extra rupee you put toward principal reduces the balance on which interest accrues.
Example Impact
On ₹5,00,000 of debt at 18% APR — adding just ₹3,000/month extra can cut your payoff timeline from 9 years to under 4 years and save over ₹2,50,000 in interest.
Mathematically, the Avalanche method (highest interest rate first) saves the most money. The Snowball method (smallest balance first) provides faster psychological wins that help some people stay motivated. Studies show people who use the Snowball method are more likely to stick with their plan. Choose whichever keeps you committed.
It depends on your balances and interest rates, but the impact is often dramatic. On $10,000 of credit card debt at 20% APR with $200 minimum payments, adding just $100/month extra cuts payoff time from 9 years to under 4 years and saves over $4,000 in interest. The earlier in the payoff process you add extra payments, the more you save.
A common guideline: always capture your full 401(k) employer match first (free money). Then pay off high-interest debt (>8–10% APR) before investing further. Low-interest debt (<5–6% APR) can often be held while investing, since historical stock market returns (~7–10%) may exceed your interest cost. Credit card debt at 20%+ should almost always be paid off before investing beyond the employer match.
