How many months does it take to pay off a credit card?
At the minimum repayment, the honest answer is measured in decades, not months. A $3,000 balance at Australia's average standard card rate of 20.99% p.a., paying a typical 2%-or-$20 minimum, takes 46 years and 6 months — and racks up about $15,341 in interest, five times the original debt. The same balance at a flat $150 a month is gone in 2 years and 1 month for $724. Run your own numbers below.
Assumes no new spending on the card, no annual or late fees, and monthly interest at rate ÷ 12. Issuers vary their minimum formulas (some add interest and fees on top of a 1% floor) — copy the rule printed on your own statement for a closer match. General information, not financial advice.
Why the minimum payment takes decades
The arithmetic is unforgiving. At 20.99% p.a., a card charges roughly 1.75% of the balance in interest every month. A 2% minimum payment therefore retires only about 0.25% of the debt per month — the other seven-eighths of your payment is rent on the loan. Worse, the minimum is recalculated on the new, slightly smaller balance, so next month's payment is smaller too. The payment and the debt shrink together, in near lock-step, and the payoff date recedes toward the horizon.
The dollar floor is what finally ends it. Most Australian cards set the minimum at 2–3% of the closing balance or a floor of roughly $10–$30, whichever is greater. Once the balance falls low enough, the floor takes over, the payment stops shrinking, and the last stretch clears comparatively quickly. That is why the schedule is so lopsided: on the $3,000 example, the first half of the debt takes far longer to clear than the second.
Rates make the trap deeper elsewhere. In the United States, the Federal Reserve's G.19 consumer credit release put the average rate on card accounts actually being charged interest at 22.15% in the second quarter of 2026 — at that rate, a $5,000 balance on a 2%-or-$25 minimum is effectively a lifetime arrangement.
Regulators decided you needed a warning label
The minimum-payment trap is well enough documented that two countries legislated warning labels for it. In the US, the Credit CARD Act of 2009 forced issuers, from February 2010, to print a "minimum payment warning" on every statement: how long the balance will take to clear at minimums, and what it costs compared to a 36-month payoff.
Australia went further. Every Australian card statement must carry a minimum repayment warning comparing your current trajectory against a 2-year payoff. And from 1 January 2019, following ASIC's Report 590, banks may no longer issue a card or a limit increase unless the customer could repay the entire limit within three years — a rule created precisely because issuers had been happy to extend limits that minimum payers could never realistically clear. Next time your statement arrives, read the warning box: it is the same calculation as the widget above, done by law.
What actually gets you out
Freeze the payment, not the debt. The single cheapest trick costs nothing: whatever your minimum is this month, keep paying that exact dollar amount every month, even as the required minimum falls. Turning a declining payment into a flat one is the entire difference between the 46-year column and the 2-year column in the calculator.
Balance transfers are a deadline, not a holiday. A 0% transfer offer (commonly 12–24 months in the Australian market, with a one-off fee around 1–3%) only works if you divide the balance by the number of interest-free months and pay that figure relentlessly. Whatever survives the promotional window flips to a revert rate that is often worse than the card you left.
Multiple cards: avalanche or snowball. Paying the highest-rate card first (the avalanche) is mathematically cheapest; paying the smallest balance first (the snowball) hands you finished-card wins sooner and is easier to sustain. The gap between them is small next to the gap between either and a life of minimums.
The minimum payment is a product feature, not a courtesy
It is tempting to read the minimum as your bank being flexible. Read it instead as pricing. A customer who pays in full is a cost centre; a customer who pays 2% a month at 21% a year is among the most profitable retail relationships a bank can hold — which is why it took an Act of the US Congress and an ASIC instrument to get the payoff math printed on the statement at all.
The number on this page isn't really "how many months." It's who sets the clock — the formula on the statement, or you.
Questions people actually ask
Will minimum payments ever pay off my credit card?
Eventually, in most cases — but "eventually" can mean decades. Because the minimum is recalculated as a percentage of a shrinking balance, the payment shrinks with the debt and the payoff tail stretches out. A $3,000 balance at 20.99% with a 2%-or-$20 minimum takes about 46 years and roughly $15,000 in interest. If the dollar floor is very low or the rate is high enough, the payment can fail to cover interest at all, and the balance never falls.
Why does my minimum payment go down each month?
Most issuers set the minimum as a percentage of your current balance (commonly 2–3%), with a small dollar floor. As the balance drops, so does the required payment. That feels like relief, but it is exactly what stretches payoff into decades. The fix costs nothing: keep paying this month's minimum amount every month even as the required figure falls.
Is a balance transfer worth it?
It can be, if you treat the 0% window as a deadline rather than a holiday. Transfers usually charge a one-off fee of about 1–3% of the balance, and any debt left when the promotional rate ends flips to a high revert rate. Divide the transferred balance by the number of interest-free months and pay that amount every month — the calculator above shows what the same discipline achieves even without a transfer.
Should I pay off the highest-rate card or the smallest balance first?
Highest rate first (the "avalanche") is mathematically cheapest. Smallest balance first (the "snowball", popularised by US radio host Dave Ramsey) costs a little more in interest but retires whole cards faster, which many people find easier to stick with. Either beats paying minimums across the board — pick the one you will actually follow.
