Time to debt-free
Good to know This is a general estimate that assumes a fixed interest rate, a fixed monthly payment, and no new charges or fees on the balance. Real-world results vary with rate changes, fees, and spending. Debt settlement and consolidation are different paths with their own trade-offs, including possible credit-score impact and taxes on forgiven debt. This is general information, not financial advice.

How the payoff math works
Each month, part of your payment covers interest and the rest reduces the balance (the principal). The higher your interest rate, the more of each payment goes to interest instead of paying down what you owe, which is why high-rate balances can feel like they barely move.
Why a small extra payment does so much
Every extra dollar goes straight to principal, which lowers the balance that interest is charged on next month. That compounds in your favor: a modest extra payment can cut years off the timeline and save a large chunk of interest. Try the "extra each month" field above to see the difference on your own numbers.
What this calculator assumes
- A fixed interest rate and a fixed monthly payment.
- No new charges or fees added to the balance.
- Interest charged monthly on the remaining balance.
Real cards and loans vary, so treat the result as a close estimate, not an exact schedule.
When a payoff plan isn't enough
If the balance is growing faster than you can pay it, there are structured options, each with trade-offs. Debt consolidation can lower your rate, a debt management plan works through a nonprofit credit counselor, and debt settlement negotiates a reduced payoff (but can hurt your credit and create a tax bill on forgiven debt). Our debt relief guide compares them.
Frequently asked questions
How is the payoff time calculated?
The calculator applies your interest rate to the balance each month, subtracts the interest portion of your payment, and reduces the balance by the rest, repeating until the balance reaches zero.
Does paying extra really save money?
Yes. Extra payments go entirely to principal, so the balance, and the interest charged on it, shrinks faster. The calculator shows exactly how much interest and time an extra monthly amount saves.
Why does my balance barely move at a high APR?
At a high rate, most of a minimum payment goes to interest. If the payment is close to the monthly interest, very little reduces the principal, so it can take years. Raising the payment changes this sharply.
Is debt settlement faster than paying it off?
Sometimes, but it carries real costs: credit-score damage, fees, and possible taxes on forgiven debt. Compare it against a payoff plan and other options before deciding.
