How the debt payoff calculator works

Each month, interest is added at your APR divided by 12, then your payment comes off the balance.

That repeats until the balance reaches zero. The months it takes and the interest added along the way are your payoff time and total interest.

The same plan runs again with your extra payment added, so you can see the months and interest it saves.

If your payment is smaller than the monthly interest, the balance never goes down, and the calculator tells you.

The formula: Each month: balance = balance + balance × (APR ÷ 12) - payment, until the balance is paid off.

Tips from the trade

  • Pay extra on the highest-interest debt first to save the most money, or the smallest balance first if quick wins keep you going.
  • When one debt is paid off, roll its payment into the next one. That rollover is what makes payoff plans speed up.
  • Card minimums often shrink as the balance falls. Keep paying the same amount instead of the new lower minimum.

Debt payoff calculator questions

How long will it take to pay off my credit card?

Enter your balance, APR and monthly payment and this calculator shows the months and total interest. It assumes no new charges and the same payment every month.

Does paying extra really make a difference?

Usually a big one. Extra payments go straight to the balance, so less interest builds up every month after.

Is this financial advice?

No. It's an estimate from the numbers you enter. Your lender's statement shows your exact balance and rate.
