Credit Card Payoff Calculator

What this calculator does

This calculator shows how long it will take to pay off a credit card balance and how much interest you'll pay along the way. You can choose one of three plans:

• Fixed payment — you commit to the same monthly amount until the balance reaches zero.
• Target months — you pick a payoff date and the calculator solves for the payment that gets you there.
• Minimum payment — you pay only what your issuer requires (typically 1–3% of the balance plus interest).

How credit card interest works

Credit cards charge interest on any balance carried past the grace period. Most cards calculate interest using an average daily balance method, but the simplified monthly equivalent is balance × APR ÷ 12. Each month, that interest is added to your balance, and your payment is split between paying that month's interest and reducing principal.

The minimum-payment trap

Issuer minimum payments are intentionally low — typically 1% of the balance plus interest. On a $5,000 balance at 22% APR, the minimum starts around $130 but quickly drops as the balance shrinks. The result: a payoff timeline that stretches 15+ years and costs more in interest than the original purchase.

This is the single most important lesson of this calculator: paying even $50 more per month than the minimum can shave years off your debt and save thousands in interest.

Tips and common mistakes

• Stop adding to the balance. No payoff plan works if you keep using the card. Switch to debit or cash while you pay off.
• Look at balance transfer offers. A 0% intro APR card can save thousands if you have the discipline to pay off during the intro window.
• Consider a personal loan. A fixed-rate personal loan at 8–12% can be far cheaper than a 22%+ credit card and gives you a firm payoff date.
• Track your APR. If your credit has improved since you opened the card, you can sometimes call and ask for a rate reduction. It costs nothing to ask.

Frequently asked questions

How is credit card interest calculated?

Credit card interest accrues daily based on your balance and the APR. The simplified monthly equivalent is balance × (APR ÷ 12). On a $5,000 balance at 22% APR, that's about $92 in interest the first month — and any payment below that amount means your balance grows.

Why does paying just the minimum take so long?

The minimum payment is typically 1–3% of the balance plus that month's interest, with a $25–35 floor. Because the percentage is so small, your balance only shrinks by 1% a month before interest is added back the next month. On a $5,000 balance at 22% APR, the minimum-only schedule can take 15+ years and cost more in interest than the original purchase.

What is a balance transfer and is it worth it?

A balance transfer moves debt from a high-APR card to one with a 0% intro APR for 12–21 months. If you can pay off the balance during the intro period, you can save thousands in interest. Watch out for the balance transfer fee (typically 3–5%) and make sure you can pay off the balance before the rate jumps.

How does APR really affect what I owe?

APR is the annual cost of carrying a balance. The higher the APR, the more of your monthly payment goes to interest instead of reducing the balance. Cutting APR from 22% to 10% (e.g., via balance transfer or credit-union personal loan) can cut your payoff time and interest cost by more than half.

Should I pay off debt or build savings first?

A common rule of thumb: build a $1,000 starter emergency fund first so unexpected expenses don't push you back into debt, then attack high-interest debt aggressively before building a full emergency fund. High-APR credit card debt is essentially a guaranteed negative return — paying it off beats almost any investment.

What is the snowball vs avalanche method?

With multiple debts, the snowball method pays off the smallest balance first for psychological wins; the avalanche method targets the highest APR first to minimize total interest. The avalanche saves more money mathematically; the snowball can be easier to stick to. Both work — pick the one you'll actually follow.
