How the Credit Card Payoff Calculator Works
This calculator models three payoff scenarios for your credit card balance: minimum payments only, a fixed monthly payment (equal to your current minimum), and fixed payment plus extra. It shows the dramatic difference in payoff time, total interest, and total cost between these strategies.
The Minimum Payment Trap
Most credit cards set the minimum at 1–3% of your balance or a flat amount like $25, whichever is greater. As your balance drops, so does the minimum — meaning you pay less and less each month. On a $5,000 balance at 22% APR with a 2% minimum, it takes over 30 years to pay off and costs more in interest than the original balance.
Why Fixed Payments Are Better
If your first minimum payment is $100, keep paying $100 every month even as the minimum drops. This simple change can cut your payoff time in half because you're consistently reducing principal instead of letting payments shrink. Adding even $50–$100 extra per month accelerates payoff dramatically.
How Credit Card Interest Works
Credit card interest uses your average daily balance multiplied by the daily periodic rate (APR ÷ 365). Interest compounds daily, not monthly like a mortgage. That's why a 22% APR credit card costs far more than a 22% simple interest loan over the same period.

Frequently Asked Questions
How long does it take to pay off a credit card with minimum payments?
Paying only the minimum (typically 2% of balance or $25) on a $5,000 balance at 22% APR takes over 30 years and costs more than the original balance in interest. This is the "minimum payment trap" — as your balance drops, your payments shrink, and most of each payment goes to interest.
What is the minimum payment trap?
Credit card minimum payments decrease as your balance drops (e.g., 2% of balance). Early on, you pay $100/month on a $5,000 balance. But as the balance drops to $1,000, your minimum falls to just $25 — barely covering interest. This extending payoff for decades. Switching to a fixed payment amount eliminates this trap.
Is it better to make fixed payments or minimum payments?
Fixed payments are dramatically better. If your first minimum is $100, keep paying $100 every month. This alone can cut payoff time in half compared to always paying the decreasing minimum. Adding extra on top saves even more.
Should I get a balance transfer card?
If you have good credit (680+) and high-APR debt, a 0% balance transfer card can save hundreds or thousands. Most charge a 3–5% fee, but that's usually far less than the interest you'd pay at 20%+ APR. The key is paying off the balance before the promotional period ends (typically 12–21 months).
Does paying off credit card debt improve my credit score?
Yes, significantly. Paying down cards lowers your credit utilization ratio (~30% of your FICO score). Going from 80% to under 30% utilization can boost your score 50–100 points. Keep cards open after paying them off — closing them reduces available credit and can hurt your score.
How is credit card interest calculated?
Credit card interest uses your average daily balance × daily periodic rate (APR ÷ 365). Interest compounds daily on your remaining balance. A 22% APR means about 0.06% per day. This daily compounding is why credit card debt grows faster than other loan types.
How much should I pay on my credit card each month?
Pay at least 2–3x the minimum payment. Ideally, pay the full statement balance to avoid interest entirely. If you can't pay in full, every extra dollar beyond the minimum reduces payoff time and total interest. Even $50–100 extra per month can save thousands.
