an exit plan.
Estimate the payoff date and interest, then put an extra monthly amount next to it. The full schedule shows where every estimated payment goes.
Private by default. Balances and payments are calculated in this tab. Nothing is uploaded, stored, or connected to a financial account.

Build the payoff plan
Estimates use APR ÷ 365 and the actual days in each projected billing month.
Assumptions: no new purchases, fees, penalty rates, or missed payments. Payments happen once per projected monthly cycle.

Useful math, honest limits01 02 03
A planning estimate, not your statement.
Daily-rate estimate
Each cycle estimates interest using the current balance, APR divided by 365, and the calendar days until the next projected payment.
Cents stay cents
Interest, principal, balances, and payments round to cents each month, so the schedule behaves more like money than an infinite-decimal formula.
Your issuer has the final number
Card issuers may use average daily balances, different cycle dates, fees, grace periods, and transaction timing. Check your statement before making a decision.
Credit card questions.
Why might my actual interest be different?
Issuers commonly calculate interest from daily balances and the exact transactions in a billing cycle. This calculator has one monthly balance and cannot know purchases, credits, fees, or payment posting time. The Consumer Financial Protection Bureau explains common methods.
Does the extra payment always save interest?
In this no-new-purchases estimate, a larger payment reduces principal earlier and generally lowers future interest. Your card terms and payment timing still control the real result.
Is this financial advice?
No. It is a general educational estimate, not financial, legal, tax, or credit counseling advice. Confirm rates and payoff amounts with your card issuer.
