Credit Card Payoff Formula
The Credit Card Payoff Formula helps you calculate exactly how many months it will take to pay off your credit card balance, given your current balance, interest rate, and monthly payment. It's a powerful tool for financial planning and debt management.
Formula
Copy the exact expression or work through it step by step below.
Months To Pay Off = -ln(1 - Monthly Rate x Card Balance / Monthly Payment) / ln(1 + Monthly Rate) Variables
MPO
Months To Pay Off
The months to pay off value plugged into the credit card payoff calculation.
MR
Monthly Rate
The monthly rate assumption used in the credit card payoff calculation.
CB
Card Balance
The card balance value plugged into the credit card payoff calculation.
MP
Monthly Payment
The recurring amount that changes the credit card payoff result over time.
Step By Step
- 1
Set the baseline case with the real calculator inputs.
Balance = $8,500, APR Percent = 23.0%, Monthly Payment = $250
- 2
Translate rates, periods, and cash values onto the same footing before combining them.
Keep the credit card payoff assumptions consistent instead of mixing monthly and annual views.
- 3
Apply the formula and read the first calculator outputs, not just the headline assumption.
The calculator lands with months to payoff at 56 and total interest paid at $5,383.
- 4
Run one changed scenario so the formula is stress-tested before it is trusted.
The credit card payoff calculator page is the fastest way to compare that second case.
