Accelerate Your Credit Card Debt Elimination
Our Credit Card Payoff Calculator is built for individuals with high-interest credit card debt. Credit cards carry some of the highest APRs of any consumer debt, making prepayments a high-yield strategy to protect your wealth and achieve debt freedom.
The Compounding Math of Credit Card APR
Credit card companies compute interest daily based on your average daily balance:
When you only pay the minimum required amount, the bank allocates almost all of it to cover daily interest charges. By making an extra payment, 100% of the extra amount directly attacks the principal balance, immediately lowering your average daily balance for the next month's calculation.

Worked Numerical Example
Let's look at a credit card balance of $12,000 at a 19.99% interest rate over a 5-year amortization term, with an extra payment of $150/month:
- Credit Card Balance: $12,000
- Interest Rate: 19.99% (APR)
- Term: 5 Years (60 Months)
- Standard Monthly Payment: $317.93
- Extra Monthly Payment: $150.00
| Payoff Option | Monthly payment | Total Interest Paid | Total Cost of Debt | Payoff Timeline |
|---|---|---|---|---|
| Standard Schedule | $317.93 | $7,075.80 | $19,075.80 | 5.0 Years |
| Accelerated Prepayment | $467.93 | $4,120.12 | $16,120.12 | 3.1 Years |
| Total Savings | +$150.00 / month | $2,955.68 Saved | $2,955.68 Saved | 1.9 Years Saved |
