Credit card interest compounds daily in the United States. Your card issuer divides your APR by 365 to get a daily periodic rate, then applies that rate to your average daily balance each day of the billing cycle.
For example, at 24% APR the daily rate is 24 ÷ 365 = 0.0658%. On a $5,000 balance, that’s about $3.29 per day in interest — roughly $99 per month. This credit card payoff calculator uses the simplified monthly compounding model, which closely approximates the real outcome.
Interest accrues whenever you carry a balance past your grace period. If you pay your full statement balance by the due date each month, you owe zero interest — the grace period protects you.
Credit card issuers typically set minimum payments at 1–2% of the balance (or $25, whichever is greater). This keeps your account current but pays barely more than the monthly interest charge — leaving the principal almost untouched.
On a $5,000 balance at 24% APR with minimum payments only, it can take 15–20 years to pay off, and you'll pay more in interest than the original balance. Every extra dollar above the minimum goes directly toward principal reduction and saves a compounding multiple in future interest.
Because credit card interest compounds, small increases in your monthly payment have an outsized effect. Use this as a payoff calculator: try bumping your payment by $50/month on a $3,000 balance at 22% APR and you can cut the payoff time in half and save hundreds in interest.
The most effective strategy: treat your credit card payment like a fixed bill, not a variable cost. Set the payment to a fixed dollar amount (not "minimum due") and increase it as you can.
There are two main methods for paying off multiple cards:
If you carry a high-APR balance, consider whether a balance transfer card with a 0% introductory period makes sense. Many cards offer 12–21 months of 0% APR on transferred balances, which can eliminate interest entirely if you can pay off the balance before the promotional period ends.
The average credit card APR in the U.S. is around 20–27% (as of 2024). Rates vary by card type: rewards cards tend to run higher, while cards aimed at people with excellent credit can offer 15–18%.
Does credit card interest compound daily or monthly?
Daily. Your APR is divided by 365 to get a daily periodic rate, and interest accrues on your average daily balance every day of the billing cycle. This calculator uses monthly compounding as a close approximation — the difference from daily compounding on a typical balance is less than a dollar per month.
What happens if I only pay the minimum each month?
Your balance decreases very slowly because most of the minimum payment covers interest rather than principal. At 24% APR, paying the 2% minimum on a $5,000 balance can take over 15 years and cost more than $4,000 in interest. The balance transfer or payoff strategies above can dramatically shorten this timeline.
Is it better to pay off credit cards or invest the extra money?
It depends on the APR. If your card charges 20%+ APR, paying it off is a guaranteed 20% return — better than virtually any investment. If your APR is low (say, 8%), it may make sense to invest in a tax-advantaged account first (especially if you have an employer match). In practice, most credit card rates today make payoff the better financial move.
What is the grace period and how do I keep it?
The grace period is the window between your statement closing date and your payment due date — typically 21–25 days. If you pay your full statement balance by the due date, you owe no interest on those purchases. If you carry a balance even one month, the grace period goes away and interest accrues on new purchases from the day they post. To get the grace period back, you must pay the full balance two months in a row.
Will a balance transfer hurt my credit score?
Opening a new card causes a small temporary dip from the hard inquiry (typically 5 points or less). But reducing your overall utilization by consolidating balances usually improves your score over the medium term. The key is not closing old accounts after transferring — that reduces your available credit and raises your utilization ratio.
