Credit Card Payoff Calculator

Freezing the payment at month one, before finding a single extra dollar

Take one card on its own: $3,000 at 24.99% with a typical 1% + interest minimum, about $93 in month one. Paying only the recalculating minimum, the balance does not reach zero within 50 years. Paying a flat $150 a month instead clears the same card in 27 months for about $921 of interest — same card, same rate, the only difference being that the payment is not allowed to shrink.

Because the minimum is recalculated from a falling balance, the principal you retire decelerates every month, and when the formula asks for less than the month’s interest the balance never finishes at all — which is why the minimum-only baseline beside every strategy reports “Never” rather than a date. That baseline is what your own plan should be measured against.

$10,000 across the three cards loaded above asks $222.25 in minimums in month one, and the first two rows below both send exactly that.

The freeze costs nothing and it is what turns a balance that never clears into one that clears in 100 months. Then compare the last two rows: the same $422.25 starting outlay, 32 months and $3,209 frozen, against 46 months and $4,158 with the minimums left free to shrink — the same money, refused permission to decline.

Four minimum-payment rules on one balance at one APR

The same $5,000 at the same 22.99%, paying the minimum and nothing else. The only thing changing is the rule that defines that minimum.

A percent-of-balance rule pays a shrinking slice of principal forever, which is why row two is still unpaid at the 50-year mark; adding the month’s interest on top, as row three does, fixes the interest bill but leaves the balance falling only 1% a month. The ranking also flips between the last two columns: the flat $100 clears 43 months sooner than the 3% rule yet costs about $4,196 more in interest, because the 3% rule front-loads repayment while the balance is still large.

Which of those four sentences governs your account is the one input this page cannot guess for you, and it sits in your cardholder agreement: a percent of the balance, typically 1% to 3%; that percent plus the month’s interest and fees; or a flat floor — and where two are quoted together, normally whichever is greater. The calculator models all four shapes, per card, so copying your card’s actual rule across is the single change that most moves the answer.

The monthly payment at which a 3% transfer fee starts paying for itself

$6,000 moved off a 14.99% card onto a 12-month 0% offer with a 3% fee, reverting to 26.99%. A low-rate source card is where a fee actually bites, because the interest being avoided is small to begin with.

The scenario module weighs three numbers: the fee added upfront, the interest avoided inside the intro window, and whatever is still outstanding when that window closes and reverts to the post-promo APR. A transfer wins when you clear most of the balance before the window shuts, and loses when new spending quietly refills the card the balance came off. The module returns a break-even month, or a plain “not beneficial” verdict when the fee wins.

The fee stops being worth paying below about $180 a month. At the top row the transfer costs $644 more than doing nothing, because $4,380of the balance is still sitting there when the 0% ends and it reverts to a higher rate than the card it came from. The saving also peaks mid-table: past a certain payment the debt would have cleared quickly anyway, leaving less interest for the offer to avoid. Approval, the limit granted, and the promo terms are the issuer's decision, never a given.

The month your utilization drops under 30%, and what that date does not promise

Utilization is your balance divided by your credit limit, per card and again across every card together. Widely cited guidance suggests staying under about 30%, with lower generally described as better. The meter beside each card tracks that ratio through the whole payoff plan, so what you get back is a date: the month each card first falls under the line, and the month your combined ratio does — on a plan that targets one card at a time, often months apart.

Read that date as a progress marker and nothing more. This page makes no credit-score promise and cannot make one: scoring models are proprietary, that 30% line is a guideline rather than a published threshold inside any model, and no simulation can tell you what a bureau will do with a lower ratio or when.

The highest utilization order attacks the card sitting furthest above the line first, which brings the meter down soonest. Avalanche attacks the highest APR first, which is normally the order that leaves the smallest interest total. Run both and compare the payoff date and the total interest: if they disagree by a month and a few dollars, take the utilization; if avalanche is hundreds of dollars cheaper, the meter is an expensive thing to hurry.

Five payoff orders, twenty cards, and a deadline solved backwards

The tool itself takes up to 20 cards at once, each with its own balance, APR, limit, minimum rule, promo APR, fee and new charges, simulated together month by month with interest accruing at each card’s own rate and whatever your budget leaves over aimed by the strategy you chose.

Snowball is here — smallest balance first — as one of five payoff orders, alongside avalanche (highest APR first), highest minimum, highest utilization, and a custom order you set card by card. They are heuristics rather than standards. The budget itself can be weekly, bi-weekly or monthly, with each card’s minimum recalculated every period, and a fixed total can be held steady so freed-up minimums roll down instead of evaporating.

The date solver runs the same engine in reverse. Instead of entering a payment and reading off the finish month, switch to Debt-free by date, name the month you want to be clear, and the tool returns the monthly amount that deadline requires.

The month-by-month detail exports as a standard 9-sheet XLSX workbook, which Google Sheets opens and converts natively through File > Import, or by uploading it to Drive. Each row is one card in one month: the balance carried, the interest charged, the payment applied. That is a payoff schedule for revolving debt, not the fixed-term amortization a loan produces, because both the minimum and the balance keep moving.

Where this monthly model and your statement will disagree

Four lines of arithmetic run for every card in every simulated month.

The divergence begins with that first card: because your issuer accrues daily and this page does not, paying on the 2nd rather than the 27th changes your real interest and changes nothing here. Use this page to choose between plans, where both sides carry the same convention, and the statement — never this page — for the amount that actually settles the account.

What the simulation holds fixed while you move one input:

• Interest accrues monthly at APR ÷ 12 on the current balance; issuers typically accrue daily on the average daily balance, so statements will differ slightly.
• Minimum payments are recalculated every month from your card’s rule — fixed, % of balance, % + interest, or greater-of — the way issuer formulas work.
• Promotional APRs apply through their end month, then revert to the standard APR. Annual fees post in month 1 and every 12 months after.
• The balance-transfer scenario compares against your cards’ blended APR; approval, limits, and exact terms are the issuer’s decision.
• The simulation caps at 600 months; anything longer reports as not amortizing rather than a fake date.

The rest of the gap is what a monthly model deliberately does not carry. Flattening each card into one payment a month is what makes five strategies comparable on one screen, and it is also why this page cannot produce the binding number. The limitations to keep in view:

• Not an issuer payoff quote — the official payoff amount, interest, and minimum on any date come from your card issuer.
• Grace periods, daily compounding, payment-allocation rules on multi-rate balances, and country-specific regulations are simplified to a monthly model.
• Utilization is shown as a progress meter; no credit-score outcome is promised or predicted.
• No consolidation, settlement, or bankruptcy advice — those are separate decisions for qualified humans.

Sources and methodology

This calculator amortizes the balances, APRs and payments you enter, month by month, in your browser. It is never an issuer payoff quote: it does not know your statement date, your daily periodic rate, your grace period, trailing interest, promotional or deferred-interest balances, or the exact formula your issuer uses for your minimum payment. Those come from your card agreement, not from law.

What law does fix is the disclosure this page mirrors. The minimum-only baseline shown against every strategy - how long the balance takes to clear, and what it costs in total, if you pay only the minimum - is the same pair of figures the Credit CARD Act of 2009 and Regulation Z require your issuer to print on each statement, so those rules are cited below alongside the legal definition of the APR you type in. The avalanche and snowball orderings this page offers are a different matter: they are popular heuristics, not official methods, and no law, regulator or standards body certifies either one.
