Credit Card Payment Calculator
Print| Total Interest Paid | $0.00 |
Take control of your revolving credit card balances. Use this Credit Card Payment Calculator to calculate exact monthly payments required to pay off your credit cards within a specific timeframe (e.g., 12, 24, or 36 months), project total interest charges, and structure a custom debt payoff plan.
The Formula for Fixed Credit Card Payoff Payments
Calculating the fixed monthly payment required to pay off a credit card balance within a target number of months relies on loan amortization mathematics:
Monthly Interest Rate (r) = Annual APR / 12
Required Monthly Payment (PMT) = P × [r(1 + r)^n] / [(1 + r)^n - 1]
Total Interest Paid = (PMT × n) - P
Where:
- P: Current total credit card balance.
- r: Monthly interest rate decimal (e.g., 21.0% APR / 12 = 0.0175).
- n: Target payoff duration in months (e.g., 12, 24, or 36 months).
- Assumed Condition: No new purchases are added to the credit card balance during the payoff period.

Step-by-Step Credit Card Payment Example
Suppose you owe $6,000 across two credit cards charging an average 20.0% APR and target becoming completely debt-free in 24 months:
- Convert APR to Monthly Rate: 20.0% / 12 = 0.016667 per month.
- Apply Amortization Formula: $6,000 × [0.016667(1 + 0.016667)^24] / [(1 + 0.016667)^24 – 1] = $305.21.
- Determine Fixed Monthly Payment Needed: Pay $305.21 per month for 24 consecutive months.
- Calculate Total Payments Made: $305.21 × 24 months = $7,325.04 total outlay.
- Calculate Total Interest Paid: $7,325.04 total outlay – $6,000 principal = $1,325.04 total interest paid.
Frequently Asked Questions
Why is setting a fixed monthly credit card payment better than paying minimums?
Minimum payments decrease as your balance drops, prolonging debt for 15 to 25 years. Setting a fixed monthly payment maintains aggressive principal reduction every month, cutting payoff timelines by over 80%.
Should I stop using my credit card while paying off the balance?
Yes, continuing to make new purchases adds to your principal balance and forfeits your grace period, causing new transactions to accrue interest immediately.
How does consolidating credit cards into a personal loan lower payments?
Personal loans offer fixed interest rates (typically 8% to 14% APR) that are much lower than credit card APRs (20% to 28%), lowering your required monthly payment and locking in a structured payoff date.
What if I cannot afford the calculated monthly payment for my target date?
If the monthly payment for a 12 or 24-month payoff exceeds your budget, extend your target date to 36 months, or consider a 0% APR balance transfer card to reduce monthly interest charges.
