Debt Payoff Calculator
Use this debt payoff calculator to estimate how long it could take to pay off your existing debts, what total interest may cost you over time, and how much faster extra monthly payments could get you to a debt-free date.
It is built for practical consumer-debt planning: credit cards, personal loans, store cards, and other debts you are already repaying. The focus is on payoff timeline and extra-payment impact, not on comparing snowball versus avalanche strategies.
This version pays minimums on every debt and applies extra monthly payment to the highest APR debt first, then rolls freed payment capacity forward as each debt is paid off.
Results are planning estimates only. Real payoff figures can differ because statement timing, fees, daily-interest methods, and lender rules vary.
How to use this calculator
- Enter each debt's current balance, APR, and minimum monthly payment.
- Add any extra monthly payment you can put toward debt above the minimums.
- Calculate to compare your payoff timeline with extra payments against a baseline minimum-payment-only scenario.
- Review the estimated debt-free date, months to payoff, total interest, time saved, and interest saved.
- Check the debt-by-debt summary and payoff progress chart to see where the biggest time and interest impact comes from.
This works well for credit card debt, personal loans you are already repaying, store cards, and similar consumer debts where your goal is to get debt-free sooner.
How it works
This calculator estimates a debt payoff timeline by adding monthly interest to each debt, paying all minimums, and then applying the extra payment to the highest APR debt first.
It is designed to answer practical payoff questions like how long until you could be debt-free, how much interest you may pay, and how much extra monthly payments could help.
How the payoff estimate is built
- Each month, the calculator adds interest based on the APR entered for each active debt.
- It then applies the minimum payment to every active debt before the extra payment is applied to the highest APR debt first.
- When one debt is paid off, its minimum payment is effectively rolled into future payoff capacity for the debts that remain.
- A baseline scenario with no extra monthly payment is also calculated so time saved and interest saved can be estimated.
Assumptions and limitations
- Interest is estimated monthly based on the APR you enter for each debt.
- Minimum payments are made on all active debts each month before extra payment is applied.
- Extra monthly payment is applied to the highest APR debt first, and freed payment capacity rolls forward automatically.
- Real lender calculations, statement timing, fees, and daily-interest methods may differ from this estimate.
Example scenario
Use this example to see how extra monthly payments can change a real-world debt payoff timeline.
- Credit card:
$6,200balance at22.9%APR with a$185minimum payment - Personal loan:
$9,800balance at11.5%APR with a$260minimum payment - Store card:
$1,800balance at26.9%APR with a$65minimum payment - Extra monthly payment:
$200
With those assumptions, the estimated debt-free date is about Oct 2028 from a March 2026 starting point, or roughly 31 months to payoff.
Total interest paid with the extra payment is about $3,841.53.
Compared with minimum payments only, that saves about 18 months and roughly $3,335.85 in interest.
This example highlights the page's main planning value: a consistent extra payment can change both the payoff timeline and the total interest cost in a meaningful way.
Frequently asked questions
How do extra payments affect the payoff timeline?
Extra payments can shorten the payoff timeline because more of your money goes toward principal instead of future interest. The earlier you add extra payments, the bigger the potential impact can be.
Are minimum payments enough to get out of debt?
Minimum payments may eventually pay off some debts, but they can stretch the timeline and increase total interest. In some high-interest situations, minimum payments may not be enough to produce a timely payoff.
Does this work for credit card debt?
Yes. It works well for credit cards, personal loans, store cards, and other consumer debts where you want to estimate payoff timing and the effect of extra payments.
Can I include multiple debts?
Yes. This version supports multiple debts and applies extra monthly payment to the highest APR debt first while still covering minimum payments on the rest.
Why is high-interest debt so expensive over time?
High APR debt can add interest quickly each month, which means more of your payment goes to interest instead of reducing the balance. That is one reason extra payments can be so valuable on higher-rate debts.
Is this an exact payoff quote from my lender?
No. This is a planning estimate only. Real payoff figures can differ because statement timing, daily interest methods, fees, and lender rules vary.
