Calculation method
Interest accrues monthly at APR ÷ 12. Minimums are paid first; remaining budget goes to the highest APR or smallest remaining balance. The original monthly budget stays constant as debts are cleared.
Assumptions and limitations
No new borrowing, fees, changing APRs, or changing minimum-payment formulas. Zero-balance debts do not add a minimum to the budget. Payoff is limited to 1,200 months. The combined budget must exceed monthly interest. Actual lender billing may differ.
