How the Credit Card Debt Payoff Calculator Works

Compares minimum payment schedules against fixed target payments, showing total interest paid, months to debt-free, and potential savings.

Formula

N = -log(1 - (r × PV) / PMT) / log(1 + r)

Calculates the number of periods (N) to pay off a present value (PV) given regular payments (PMT) and interest rate (r).

Calculation Example

Paying $100/mo on a $5,000 balance at 18% APR takes 94 months and costs $4,311 in interest.
