Starting examples: credit card $5,300, the average balance per cardholder (CFPB, Dec 2025), at 22.36%, the average rate on card accounts charged interest; personal loan at 11.90%, the average 24-month personal loan rate; car loan at 7.54%, the average 60-month new car loan rate (Federal Reserve G.19, August 2026, released Oct 7, 2026). Balances, minimums and the extra $200 are example amounts. Interest is charged monthly at APR ÷ 12; every minimum is paid first, then the extra goes to the target debt, and each paid-off debt's minimum rolls into the next. Our calculation.
