How Credit Card Interest Works
Credit card interest is calculated monthly on your remaining balance. Your annual interest rate is divided by 12 to get a monthly rate — that rate is then applied to whatever you still owe. This means if you only make minimum payments, most of your payment goes toward interest rather than reducing your actual debt.
Formula: Monthly Interest = Balance × (Annual Rate ÷ 12 ÷ 100)
For example on a $5,000 balance at 20% annual interest: $5,000 × (20 ÷ 12 ÷ 100) = $83.33 interest per month
Why Minimum Payments Are a Trap
Credit card minimum payments are typically set at 1-2% of your balance or a fixed minimum — whichever is higher. At these rates most of your payment covers interest with very little reducing your actual balance. A $5,000 balance paying only the minimum could take 20+ years to pay off and cost thousands in interest.
How to Pay Off Credit Card Debt Faster
Pay more than the minimum — even $25-50 extra per month makes a significant difference. Use the extra payment field above to see exactly how much you’d save.
Pay fortnightly instead of monthly — making half your monthly payment every two weeks means you make 26 half-payments (13 full payments) per year instead of 12.
Target the highest interest card first — if you have multiple cards pay minimums on all and put extra funds toward the highest rate card (avalanche method).
Consider a balance transfer — moving your balance to a 0% interest card gives you time to pay down the principal without interest charges.
FAQs
How is credit card interest calculated?
Your annual rate is divided by 12 to get a monthly rate. That rate is multiplied by your remaining balance each month. The result is added to your balance before your payment is applied — which is why minimum payments keep you in debt so long.
What happens if I only pay the minimum?
Minimum payments are designed to maximise interest income for the card issuer. Most of each payment covers interest with very little reducing your balance. This calculator shows exactly what minimum payments cost you over time.
How much extra should I pay each month?
Even $25-50 extra per month can save hundreds in interest and cut months off your repayment. Use the extra payment field to see the exact impact for your situation.
What is a good credit card interest rate?
Average credit card rates in 2025 range from 15-24% APR. Anything above 20% is considered high. If your rate is above 20% consider a balance transfer to a lower rate card.
Should I pay off credit card debt or save?
Generally pay off high interest credit card debt first — a 20% interest rate on debt costs more than almost any investment can earn. Once debt is cleared redirect those payments to savings.
