This gives you frameworks for debt payoff decisions, including avalanche versus snowball comparisons with actual interest calculations, refinancing breakeven analysis, and debt consolidation evaluation. It handles the math for debt-to-income ratios (important for mortgage qualification), payoff timelines with extra payments, and the opportunity cost analysis when deciding whether to pay down low-rate debt or invest instead. The worked examples show side-by-side comparisons with real numbers, like comparing three debts under both strategies to see the actual time and interest differences. It balances mathematical optimization with behavioral psychology, acknowledging that snowball might cost slightly more but keeps people motivated enough to actually finish.
