Credit card payoff calculator

Start with one statement and one decision

This calculator answers two different questions without forcing both into the first screen. The three visible inputs estimate how long one fixed monthly payment could take to clear one balance. Open the optional target only when you also want to know the monthly payment that would mathematically clear that same balance in a chosen number of months.

Copy the balance and APR from a current statement before entering a payment. A card can show separate purchase, balance-transfer, cash-advance, or promotional balances with different APRs. Do not blend those categories into one guessed rate. If several rates apply, calculate each category separately and remember that the issuer’s payment-allocation rules still control the real account.

How the current-payment path is modeled

The calculator divides the entered APR by 12, adds one modeled month of interest to the remaining balance, and subtracts the fixed payment. It repeats that sequence until the balance reaches zero. The final payment is reduced to the amount still due, so the reported total does not include an artificial overpayment.

The first-month split is the quickest reality check. Interest is calculated first; the rest of the actual payment reduces principal. If the payment does not exceed the first modeled month of interest, the balance cannot decline under these assumptions. A payment only slightly above interest may reduce principal while still producing an extremely long payoff.

How the target-payment answer is solved

When a target term is entered, the calculator uses the standard fixed-payment amortization formula to solve for an equal monthly payment over that many months. With a zero APR it simply divides balance by months. The target panel compares that payment with the amount already entered and shows the modeled interest difference.

The target answer is mathematical, not a claim that the payment is affordable or that an issuer will accept a special schedule. It does not replace the required minimum payment, due date, or card agreement. If the target payment strains rent, food, utilities, insurance, taxes, or other required debts, change the term or seek help rather than treating the output as an instruction.

Read the result in decision order

1. Confirm that the starting balance and APR match the intended statement category.
2. Compare first-month interest with first-payment principal. This shows whether the entered payment is making meaningful progress.
3. Read payoff time, total interest, and total paid together. A lower payment is not cheaper when it keeps the balance outstanding longer.
4. If a target was entered, compare the required payment and monthly adjustment with cash actually available after essential obligations.
5. Save the assumptions and reconcile the estimate with the next statement before relying on the projected payoff month.

The illustrative payoff month assumes the first payment occurs about one month from today and every later payment follows monthly. It is a planning label, not a due date. Use the date printed by the issuer and allow enough processing time for the payment method selected.

Your statement can calculate interest differently

The Consumer Financial Protection Bureau explains that many issuers calculate interest daily, often from an average daily balance. Actual charges can therefore change with statement length, transaction and payment timing, compounding, grace-period status, fees, rounding, promotional expiration, and rate changes. The simplified monthly model is useful for a comparable scenario, but the account statement remains the source of record.

Payments can also be allocated across balances with different APRs under rules that this one-balance model does not reproduce. A card carrying both a promotional transfer and regular purchases should not be represented as one combined balance at one blended APR. Use separate scenarios to understand scale, then verify how the issuer applies the required minimum and any amount paid above it.

Compare the result with the statement’s payoff disclosure

U.S. periodic statements generally include a minimum-payment warning and estimates based on making no additional charges. The CFPB’s explanation of the three-year payoff box notes that the disclosed amount is based on the current statement balance and does not include future purchases. Compare the calculator with that issuer-produced disclosure. A large difference is a reason to check the APR category, payment assumption, fees, and interest method rather than averaging the two answers.

New charges break a fixed-balance plan

The model assumes no new purchases, transfers, cash advances, fees, missed payments, or APR changes. It also holds the entered payment constant rather than recalculating a declining statement minimum. Continuing to charge expenses adds principal, and paying only a changing minimum can materially extend payoff. A usable plan needs both a payment and a way to avoid replacing the paid-down balance with new charges.

If the card still must cover essential expenses, build a cash-flow plan before choosing an aggressive target. The result should leave room for irregular bills and a small disruption buffer; otherwise one surprise can force another charge or missed payment. Use the monthly budget calculator to test the payment inside the household budget and the emergency fund calculator to separate revolving debt from near-term cash needs.

When the required payment is unaffordable

Do not wait for a missed payment to start the conversation. The CFPB advises consumers who cannot pay a credit card bill to contact the card company immediately, explain what they can afford and for how long, and consider carefully screened nonprofit credit counseling. That guidance also warns about debt-settlement firms that guarantee results, demand upfront fees, or tell consumers to stop communicating with creditors or stop making required payments.

A hardship arrangement, reduced rate, fee waiver, debt-management plan, settlement, or bankruptcy can have consequences outside this calculator. Obtain terms in writing and understand fees, tax effects, credit reporting, creditor participation, and legal consequences before agreeing. This tool does not rank those options.

Update the plan from evidence

Recalculate after each statement using the actual ending balance, applicable APR, and payment capacity. Compare the modeled balance decline with the statement’s change after removing new charges and fees. If progress is slower, investigate the difference instead of shortening the target by assumption. If income improves, test a higher fixed payment and read both the months saved and interest saved.
