Credit Card Payoff Calculator - Time to Pay Off and Interest Cost

Minimum payments, compound interest, and the date you are finally free

An $8,000 credit card balance at 22% APR with 2% minimum payments takes 30+ years to pay off. The total interest exceeds $14,000 - nearly twice the original debt. Add just $200/month above the minimum and that same balance disappears in 3 years with only $2,900 in interest. This calculator runs the simulation month by month and shows exactly where the tipping point is.

How to use this calculator - step by step

Current balance ($) - the total amount you owe on the card right now.
Annual interest rate / APR (%) - check your statement. US average is 20-25%.
Minimum payment type - percentage of balance (most common: 2%) or a fixed dollar amount.
Minimum payment value - enter 2 for 2% of balance, or a dollar amount like 200.
Extra monthly payment ($) - any amount above the minimum. Even $50 makes a big difference.
Read the results - payoff time, total interest, and savings from extra payments.

How extra payments change the payoff timeline

Starting balance: $8,000, APR: 22%, minimum: 2% of balance ($25 floor).

Extra payment	Payoff time	Total interest	Interest saved
Minimum only	31 years	$14,490	-
+$50/month	6 years 2 mo	$5,800	$8,690
+$100/month	3 years 9 mo	$3,690	$10,800
+$200/month	2 years 4 mo	$2,270	$12,220
+$500/month	1 year 2 mo	$1,070	$13,420

Why minimum payments are a trap

The payment shrinks as the balance drops. A 2% minimum on $8,000 is $160. After a year of payments, the balance might be $7,200 - so the minimum drops to $144. Less money goes to principal each month, extending the payoff timeline exponentially.

Interest compounds monthly. At 22% APR, the monthly rate is 1.83%. On $8,000 that is $147/month in interest alone. When your minimum payment is $160, only $13 goes to principal. At that rate, paying off the last dollar takes decades.

The $25 floor kicks in. Most cards have a minimum payment floor - typically $25. Once the balance drops low enough, you are paying $25/month on a $300 balance. That final stretch can take another 12-18 months all by itself.

FAQ

What APR does the average credit card charge?

As of mid-2025, the average US credit card APR is roughly 20-24% for new cards. Store cards and cards for lower credit scores can reach 28-30%. If your rate is above 20%, a balance transfer to a 0% introductory APR card can save thousands - but watch the transfer fee (usually 3-5% of the balance).

Should I pay off the smallest balance first or the highest rate?

Mathematically, paying the highest-rate card first (avalanche method) saves the most interest. Psychologically, paying the smallest balance first (snowball method) gives quick wins that keep you motivated. Both work - the worst strategy is paying only minimums on all cards. Pick the one you will stick with.

Is it worth getting a personal loan to pay off credit card debt?

If the personal loan rate is significantly lower than your card APR, yes. A 10% personal loan to pay off a 22% credit card saves roughly half the interest. The key: close the card or stop using it. Otherwise you end up with both the loan payment AND new card debt - a common trap called debt stacking.

Does this calculator account for new purchases?

No. It assumes you stop using the card and only pay down the existing balance. If you keep adding charges, the payoff timeline extends further. For the calculator to be accurate, freeze the card (literally or figuratively) and use only cash or debit while paying it off.

What is the difference between APR and interest rate?

For credit cards, they are essentially the same thing. The APR (Annual Percentage Rate) is the interest rate. Unlike mortgages, credit card APR does not include fees - it is the pure interest rate applied to your balance monthly (APR / 12). The monthly rate on a 22% APR card is 1.833%.

How much of my minimum payment goes to principal?

On a $8,000 balance at 22% APR, the first month's interest is $147. With a 2% minimum payment of $160, only $13 goes to principal - about 8% of your payment. As the balance drops, the ratio improves, but very slowly. After 5 years of minimums, you have paid $8,700 but still owe $5,100.
