Paying $200 per month
This works out how long a credit card balance takes to clear, and what it costs in interest. Enter the balance, the APR and either what you can pay each month or the date you want to be free of it.
It returns the payoff time, the total interest, and the total you will have handed over by the end.
How credit card interest works
Credit card interest is charged on your remaining balance, every month, and it compounds. So the debt grows from what is left, not from what you originally borrowed.
The APR is the annual rate. Divide it by 12 for the monthly rate: 22% APR is about 1.83% a month. On a $5,000 balance that is roughly $92 of interest in the first month alone.
That figure explains everything about card debt. A payment of $100 against a $5,000 balance at 22% clears about $8 of actual debt in the first month. Almost the whole payment goes to the lender.
Paying 50% more each month cuts the time by nearly two thirds and the interest by more than two thirds. The relationship is nothing like proportional.
What to enter
- Card balance
- What you currently owe. Use the statement balance rather than the available credit.
- Interest rate (APR)
- From your statement. Purchases, balance transfers and cash advances often carry different rates, and cash advances are usually the highest.
- Solve for
- Enter a monthly payment to find the time, or a target date to find the payment needed.
- Annual fee / other fees
- Included in the total cost, because a card with a fee and a lower rate is not automatically cheaper.
What this assumes
No new spending on the card. Adding purchases while paying it down is the most common reason a balance never moves.
The APR stays the same. Promotional and introductory rates expire, often sharply.
Payments are made on time. A missed payment can trigger a penalty APR on some cards.
How to calculate how long it takes to clear a card
Each month, interest is added first and your payment is applied after. What is left over is what actually reduces the debt.
- APR ÷ 12
- The monthly rate. 22% APR is about 1.83% a month
- balance
- What is still owed, so this shrinks as you pay
Work out the monthly interest. $5,000 at 22% APR: 5,000 × 0.0183 = about $92.
Subtract it from your payment. A $100 payment leaves about $8 to reduce the balance. A $250 payment leaves about $158.
Repeat on the smaller balance. Next month's interest is slightly less, so slightly more of the payment reaches the debt. Progress accelerates.
Pay above the minimum. Minimum payments are typically set near the interest charge, which is what stretches a balance over a decade.
See a worked example: $5,000 at 22% APR, paying $100 against $150 a month
- Balance
- $5,000
- APR
- 22%
First month's interest: $5,000 × 0.0183 = $91.67.
Paying $100 leaves $8.33 towards the debt. At that pace it takes 11.4 years and costs $8,678 in interest.
Paying $150 leaves $58.33 towards the debt in month one.
That clears it in 4.3 years for $2,798 of interest.
So $50 more a month saves about $5,880 and seven years.
$150/mo instead of $100 saves ~$5,880
Frequently asked questions
The balance barely moves. Minimums are typically set at around 1-3% of the balance, which on a high APR is close to the interest itself.
On $5,000 at 22%, a payment near the minimum can take over a decade and cost more in interest than the original debt. Card statements are required to show this, and the figure is usually a shock.
Most issuers use the average daily balance: they total your balance for each day of the billing cycle, average it, then apply the daily rate.
This means paying early in the cycle genuinely helps, because it lowers the average. It also means a purchase made on day one costs more interest than the same purchase on day 25.
On purchases, usually yes, if you pay the statement balance in full each month. Do that and you generally pay no interest at all.
Carry any balance and the grace period typically disappears, so new purchases start accruing interest immediately. Cash advances almost never have a grace period and often start charging from day one at a higher rate.
Mathematically, highest rate first (the avalanche method) always costs less. Every dollar goes where it saves the most.
The snowball method clears the smallest balance first and costs slightly more, but the early wins keep some people going. The best method is the one you actually finish. Compare both on the debt payoff calculator.
Often yes, if you clear the balance within the promotional window. Transfer fees are usually 3-5% of the amount, which is far less than a year at 22%.
The trap is the end of the promotion. If a balance remains when it expires, the rate can jump sharply. Divide the balance by the number of promotional months and commit to that payment from the start.
Because the debt is unsecured — there is no asset to repossess — and the lender is also funding a revolving line you can draw on at any time. Both add risk, and the rate covers it.
Card interest also compounds daily rather than monthly, so the effective annual cost is higher than the quoted APR. A 22% APR compounded daily works out closer to 24.6%.
Most cards are variable, priced as the prime rate plus a margin. Prime moves with the Federal Reserve's target rate, so when the Fed raises rates your card APR follows within a billing cycle or two.
The margin is the part set by your credit. It is fixed in your agreement, so improving your score does not lower an existing card's rate automatically — you would need to ask, or move the balance.
It is usually the single biggest factor within your control. Scores run 300 to 850, and lenders price in bands, so crossing a boundary can move your rate more than the points suggest.
The score is built mostly from paying on time and how much of your available credit you are using, then length of history, recent applications and credit mix.
Before applying for anything large, check your reports from all three national bureaus. Errors are common, disputing them is free, and a corrected report is the cheapest rate reduction there is.
Not federally for most cardholders. Usury limits are set by states, and issuers are typically incorporated in states with permissive rules, which is why rates can go as high as they do.
The Military Lending Act is the main exception, capping most consumer credit at a 36% military APR for active-duty service members and their dependents.
Problems people actually run into
Paying down the card while still spending on it
This is why balances sit still for years. Someone pays $300 a month and puts $250 of groceries back on, so the balance falls by $50 while the statement shows a healthy-looking payment.
If you are seriously clearing a card, stop using it. Move day-to-day spending to a debit card until the balance is gone.
Treating the minimum payment as the expected payment
The minimum is the least you can pay without defaulting. It is not a suggestion for how to clear the debt, and it is calculated to keep the balance alive for as long as possible.
Any fixed amount above the minimum works better, because as the balance falls the minimum falls too, which keeps stretching the term. Paying a flat $150 a month beats paying whatever the minimum happens to be.
