◆ METHODOLOGY & PLAIN-ENGLISH GUIDE (CLICK DOTTED TERMS FOR DEFINITIONS)

How Constant-Budget Debt Rollover Works

Banks shrink your required minimum payment slightly every month as your balance drops (typically 1% of principal plus monthly interest, with a $25–$35 floor)—stretching payoff over decades. By locking a constant total monthly debt payment, every dollar freed up as balances fall or cards hit $0 rolls automatically into your next target card.

Debt Avalanche vs. Debt Snowball

Debt directs all surplus dollars to the card charging the highest first, mathematically minimizing total interest paid. Debt targets the smallest dollar balance first to eliminate individual bills quickly while keeping the same total monthly budget.
