Loan & debt payoff calculator

How long will it take to pay this off?

See how long a loan will take to pay off with your current payment, or what monthly payment you’d need to clear it in a set time.

Use: credit cards, personal loans, car loans

Assumes: fixed rate, fixed monthly payment

Does not include fees or changing rates

Payoff summary

Using your payment and APR

Enter your balance, APR, and either your monthly payment or desired payoff time. We’ll show approximate months to payoff and total interest.

Months to payoff	–
Approx. years	–
Approx. payoff date	–
Total paid	–
Interest paid	–

These numbers assume a fixed rate and fixed monthly payment with interest compounded monthly. Real lenders may calculate differently and may charge extra fees.

Try scenarios:
Run a “minimum payment” case and an “extra payment” case. The difference is often huge on high APR debt.

How this payoff calculator works

This page estimates how long it takes to pay off a balance based on your interest rate and payment amount. It uses a monthly interest approximation to model payoff over time.

Two ways to use it

Given a payment: see payoff time and total interest.
Given a target timeline: see what payment would be needed (roughly).

Tips that make a big difference

Paying even a little more than the minimum can cut interest a lot on high‑APR debt.
If you have multiple debts, compare “avalanche” (highest APR first) vs “snowball” (smallest balance first).

How it works

This payoff estimate models your balance month by month. Each month, interest is added using a rough monthly rate (APR ÷ 12), then your payment (plus any extra payment) is applied. The result is an estimate of payoff time and total interest.

If your payment is less than the interest that accrues each month, the balance won’t go down (and payoff won’t happen).
Adding even a small extra amount every month usually reduces total interest significantly on high‑APR debt.

Worked example

Example: Balance = $10,000, APR = 18%, monthly payment = $300. This tool will estimate the payoff timeline and total interest. Now try the same numbers with an extra $50 per month to see how much time and interest you can save.

Quick FAQ

Should I use the “minimum payment” number? Use the minimum as a baseline, but test a realistic payment you can sustain.
What if I have multiple debts? This page estimates one balance. For multiple debts, run one scenario per debt or use a strategy (avalanche vs snowball) in your plan.
Do I include fees? If fees are monthly and predictable, add them to the balance or reduce the “payment” amount to account for them.

Common mistakes

Entering APR as a decimal: If the tool expects 18 for 18%, entering 0.18 will understate interest.
Forgetting extra payments are recurring: A one‑time extra payment helps, but a consistent monthly extra is often more powerful.
Ignoring rate changes: Variable rates (credit cards) can change the real payoff time a lot.

Limitations

This is a rough estimate and may differ from your lender’s exact amortization schedule.
It does not account for late fees, promotional APR periods, compounding rules that vary by lender, or changing interest rates.

Loan payoff: common questions

How does this loan payoff calculator work?

It uses the standard formulas for fixed‑rate loans with monthly compounding. For “how long with my payment”, it solves for the number of months needed to pay the balance at your payment and APR. For “what payment do I need”, it solves for the payment that clears the balance in your chosen time.

Does this include fees, changing interest rates, or penalties?

No. It assumes one constant APR, one fixed monthly payment, and no extra fees or rate changes. It’s meant as a ballpark tool, not an exact match to your statement.

Why does it say my payment is too low?

If your monthly payment is less than the interest that accrues each month, the balance would never go down. In that case the calculator shows that the payment is too low to ever fully pay off the loan with this simple model.

Is this financial advice?

No. This is a simple math helper only. Talk to a qualified professional or your lender for advice about real repayment options, and always check your actual statements and terms.
