The Technical Details
The engine computes payoff schedules sequentially in the browser.
When in ‘Fixed Monthly Payment’ mode, the number of months (N) to pay off the balance is solved using: N = -log(1 - (r * PV) / PMT) / log(1 + r) where: PV is the current card balance (present value), PMT is the fixed monthly payment, r is the monthly interest rate (APR / 12 / 100).
When in ‘Target Payoff Time’ mode, the required monthly payment (PMT) is solved using: PMT = PV * (r * (1 + r)^N) / ((1 + r)^N - 1) where N is the target number of months.
All logic is processed locally using pure JavaScript, meaning your credit card balances, APRs, and repayment strategies remain strictly private.
Frequently Asked Questions
What is APR and how does it affect my payoff?
APR (Annual Percentage Rate) is the yearly interest rate on your balance, divided by 12 to get the monthly rate applied each period. A higher APR means more interest accumulates between payments.
What is the difference between the two payment plan modes?
The fixed payment mode shows how long it takes to pay off the balance at a given amount. The target months mode calculates the required payment to become debt-free within a specific timeframe.
Is my data sent to a server?
No. All calculations run locally in your browser. Your financial information is never uploaded or stored anywhere.
Why does paying a little extra each month save so much?
Extra payments reduce the principal faster, which lowers the interest charged each period. This compounding benefit means a small payment increase can cut months off your timeline and save significant interest.
