Credit Card Payment Calculator

A card balance dies by fixed payments, not by minimums. Enter your balance, your APR and the fixed amount you can pay each month, and this calculator counts the months to debt-free and totals the interest the journey costs.

The Fixed Payment Is the Whole Secret

A credit card balance obeys the same amortization recursion as a mortgage — interest on the balance, payment against the sum — with one decisive difference: the card's required payment shrinks as the balance shrinks (usually interest plus about 1% of the balance), which stretches the schedule toward a decade and maximises the interest harvested. The escape is embarrassingly simple: freeze the payment at a fixed dollar amount, as if it were a loan. Then the recursion has a destination, countable by the loop this calculator runs — month by month, interest on the current balance, payment applied, repeat until zero. The calculator's two outputs are the travel brochure of that decision: the months to freedom, and the interest toll at your chosen speed. Its guard matters as much as its arithmetic: a payment at or below the first month's interest ($115 on the worked example) never arrives at all, and the page says so in dollars rather than letting the loop pretend.

Worked Example: $6,000 at 22.99% APR, $200 a Month

The defaults: the balance's first month of interest is $114.95 — over half the $200 payment — yet the fixed payment wins in 46 months (3 years 10 months), at a total interest cost of $3,011.78 on the $6,000 (total paid $9,011.78). Now the comparisons that make the page worth its visit: at $150 a month the same loop runs 77 months and about $5,492 of interest; at $300, 26 months and about $1,639. The interest saved per extra dollar is steepest at the start of the payment scale — the difference between $150 and $200 buys more freedom than between $250 and $300 — because every dollar above the interest line retires principal that would otherwise rent itself out again next month. Minimum payments, for the record, would keep this balance alive for well over ten years and roughly double the toll.

Avalanche, Snowball, and the Arithmetic of Morale

With several cards, the order of attack matters: the avalanche (highest APR first) is mathematically optimal — every spare dollar retires the most expensive rent first — while the snowball (smallest balance first) buys early victories that measurably improve follow-through in behavioural studies. This calculator prices either strategy one card at a time: run each balance at the payment you can aim at it, and the avalanche's advantage appears as a difference in the interest totals, to be weighed honestly against your own morale economy. What neither strategy survives is new charges on the card being attacked — the loop's no-new-charges assumption is printed on every result because it is the plan's foundation, not its fine print. One more piece of snow-and-avalanche common ground deserves printing: both begin by listing every balance with its APR and minimum, the census this calculator then prices card by card; households that skip the census invariably discover a forgotten store card mid-plan, at a store-card APR, which is why the census — boring, complete, written down — is the real first payment on any card debt.

The Statement's Own Confession

Since 2009, US card statements must print two numbers this calculator generalises: the time to clear the balance paying only minimums, and the monthly payment that would clear it in 36 months, with the total cost of each road. Issuers resisted the disclosure precisely because the minimum-only line is an indictment — on the worked example's balance it would confess to a decade-class journey and an interest toll rivalling the principal. The calculator's advantage over the statement's two printed roads is that it prices your road: the payment your budget actually holds, neither the issuer's minimum theatre nor the regulator's 36-month benchmark. Read the statement's confession first, then bring your number here; the difference between the two printed tolls and yours is the money the disclosure law was trying to hand you.

Frequently Asked Questions

Why is my card's minimum payment so much slower?

Because it is designed to shrink with the balance — interest plus roughly 1% of what remains — so the principal portion starts tiny and the schedule stretches: on the worked example's balance, minimums run well past a decade and the interest approaches $6,000, about double the fixed-$200 road. The minimum is calibrated to the issuer's yield, not the borrower's freedom; US disclosure rules now force statements to print the minimum-only payoff time and the 36-month alternative payment, a confession this calculator generalises to any payment you choose.

What if I can only pay a little above the interest?

Then the calculator's months will be long and its interest heavy — but finite, which is the entire difference: $125 against the worked example still arrives, in about eleven years (133 months, some $10,600 of interest), because each month retires a few dollars of principal and the interest line itself slowly falls. The slope near the interest floor is brutal ($10 more a month can cut a year), so the honest advice the numbers give is to find the first extra dollars anywhere — they are the highest-yielding dollars in the whole payoff, each one retiring principal that would have rented for years.

Does a balance transfer change the answer?

It changes the APR input for a promotional window — often 0% for 12–21 months against a 3–5% transfer fee — and the calculator prices the window faithfully if you enter the promo rate: the plan becomes "clear it inside the window," with the fee added to the starting balance for honesty. The trap the arithmetic reveals is the leftover: any balance surviving the window reprices to the go-to APR, and the loop at that rate must be re-run before the transfer is signed. Two runs of this page — promo window, then remainder at the real rate — are the complete audit.

Why does the calculator assume no new charges?

Because new charges are new loans joining mid-schedule, and the payoff question dissolves into bookkeeping soup — each charge with its own grace and rate tier. The fixed-payment plan the page prices is a commitment device as much as a computation: the card leaves the wallet, the payment freezes, the loop runs. Readers who must keep spending are better served modelling the card as a rolling balance with a target ceiling — a different tool for a different, harder problem — but the debt-free date this page prints is the one that exists, and it exists only under the assumption stated on its face.

Is paying extra on the card better than saving?

At 22.99% APR, retiring card principal is a guaranteed, tax-free 22.99% return — no savings account or prudent investment competes with a guaranteed rate like that, which is why the standard order of operations puts high-APR payoff after only a starter emergency fund (the fund exists so the next surprise does not re-arm the card). The calculator's interest total is the prize: on the worked example, the $3,011.78 is money that leaves by default and stays if the plan runs — few pages on this hub price a decision more directly.

Does paying twice a month help?

Slightly, and for a real reason: interest accrues on the average daily balance, so a mid-cycle payment lowers the balance the second half of the month is charged on — the saving on the worked example's scale is a few dollars a month, tens across the payoff — while the behavioural effect (two smaller hits feel easier than one large one, and payday alignment becomes automatic) plausibly exceeds the arithmetic. The calculator's monthly model absorbs the effect into its approximation; readers splitting payments lose nothing and gain the alignment, and the page's blessing is given with the size of the prize stated honestly.

What order do issuers apply my payment in?

By law and contract, most issuers apply anything above the minimum to the balance with the highest APR first — cash-advance and purchase tiers therefore die in the right order under a fixed payment — while the minimum itself is allocated by the issuer's stated hierarchy, usually to the lowest-rate balances first. The planning consequence is small but real: a balance-transfer offer's cheap tier survives longest under minimums, which is the issuer-friendly default, and melts fastest once your fixed payment's excess is aimed at the expensive tier. The calculator models a single balance at one APR; with mixed tiers, run it tier by tier in the order your excess will reach them.

How do issuers compute the interest, exactly?

Most use the average-daily-balance method: each day's balance accrues at APR ÷ 365, and the month's interest is the sum — close kin to this page's monthly model, differing in granularity (daily compounding makes the true toll a percent or two higher than the monthly loop's figure) and in grace-period rules for new purchases. The calculator's monthly recursion is the standard planning approximation — exact enough to choose payments and compare strategies, stated as the model it is. For a payoff letter to the cent, the issuer's own figure governs; for the decision, this page's governs.
