Monthly interest approximation, fixed APRs and fixed minimum amounts. No new charges or fees. Payoff month zero means that debt started with a zero balance.

How this was calculated

Add monthly interest to each balance, pay each fixed minimum, then send all remaining budget to the priority debt.

Roll freed payments into the remaining debts; keep the total monthly budget unchanged.

Formula and method

Each month, add interest, pay the entered fixed minimum on each debt, then send the remaining fixed budget to the priority balance. The highest-rate method prioritizes APR; the snowball method prioritizes the smallest remaining balance. Once a debt clears, keep its payment in the total budget.

Worked example

Two zero-interest debts of $1,000 and $500 with $100 and $50 minimums plus $150 extra use a $300 monthly budget. Both strategies clear the $1,500 total in five months.

Frequently asked questions

Are changing card minimum-payment formulas modeled?

No. Minimum amounts stay fixed, with smaller final payments. Rates, fees and new charges do not change. A zero-balance debt contributes no minimum to the starting budget.
