Debt Payoff Calculator
Minimum credit card payments are calculated to keep you paying for as long as possible — a $5,000 balance at minimum payments can realistically take over a decade to clear. This calculator shows the real timeline for any payment amount, so you can see exactly what paying more actually buys you.

How to use this calculator
- Enter your current debt balance and interest rate.
- Enter the fixed monthly payment you plan to make.
- Click "Calculate payoff time" to see how long it will take and the total interest you'll pay.
How the calculation works
Each month, interest is charged on your remaining balance, and whatever's left of your payment after covering that interest goes toward reducing principal. The calculator repeats this month by month until the balance reaches zero, tracking both the number of months it takes and the total interest paid along the way — the same logic a credit card statement uses internally, just made visible and adjustable.
A worked example
Say you owe $6,000 on a credit card at 22% APR, paying $200 a month. That balance takes about 37 months (just over 3 years) to clear, with roughly $1,300 paid in interest. Bump the payment to $300 a month instead, and the timeline shrinks to about 23 months, cutting total interest to around $760 — nearly $550 saved just by paying $100 more each month.
Frequently asked questions
What if my payment is too low to ever pay off the balance?
If your monthly payment doesn't cover the monthly interest charge, the balance will never shrink — the calculator will flag this so you know to increase your payment.
Should I pay off high-interest debt before investing?
Many financial planners suggest prioritizing debt with double-digit interest rates before investing, since guaranteed "returns" from debt payoff are hard to beat.
Does this work for multiple debts?
This calculates one debt at a time — for multiple debts, consider a debt snowball (smallest balance first) or avalanche (highest rate first) strategy and run each balance through separately.
What is the difference between debt snowball and debt avalanche?
Snowball pays off the smallest balance first for quick psychological wins, while avalanche targets the highest interest rate first to minimize total interest paid — avalanche typically saves more money, but snowball often has better follow-through for some people.
Does making extra payments always help?
Yes, as long as the extra amount goes toward principal rather than being treated as an early next payment — check with your lender that extra payments are applied correctly.
