Formula Used
Monthly Payment Calculation
The monthly payment is calculated using the formula:
Monthly Payment = (Current Balance × (APR/12)) / (1 - (1 + (APR/12))-n)
Where:
- Current Balance - Your current credit card balance
- APR - Annual Percentage Rate (as a decimal)
- n - Number of months to pay off the balance
Total Interest Paid
Total interest paid is calculated as:
Total Interest = (Monthly Payment × n) - Current Balance
Assumptions
- All calculations are based on the provided APR and minimum payment percentage.
- The calculator assumes you make the minimum payment each month.
- Results are estimates and may vary based on actual payment behavior.
Worked Example
Let's calculate the monthly payment for a $5,000 balance with a 15% APR and a 2% minimum payment:
- Current Balance: $5,000
- APR: 15% or 0.15
- Minimum Payment %: 2%
Using the formula:
Monthly Payment = ($5,000 × (0.15/12)) / (1 - (1 + (0.15/12))-n)
Where n is the number of months to pay off the balance. The calculator will determine the exact monthly payment amount based on your inputs.
| Month | Starting Balance | Interest | Minimum Payment | Ending Balance |
|---|---|---|---|---|
| 1 | $5,000.00 | $12.50 | $100.00 | $4,912.50 |
| 2 | $4,912.50 | $12.30 | $100.00 | $4,824.80 |
| 3 | $4,824.80 | $12.07 | $100.00 | $4,736.87 |
