How do I prioritize multiple debts with different interest rates?

Always pay at least the minimum on every debt to protect your credit, then direct extra dollars using one of two strategies. The avalanche targets the highest interest rate first, which minimizes total interest paid – the mathematically cheapest path. The snowball targets the smallest balance first for quick motivational wins. Either way, you make minimums on all the others and roll each freed-up payment into the next debt as balances disappear. When deciding, note any debt with special features: a 0% promo about to expire deserves attention before the rate jumps, and secured debts (car, home) carry collateral risk that can outweigh a slightly lower rate. Tax-deductible or low-rate debt like a mortgage generally goes last. Pick avalanche if you're rate-driven, snowball if you need momentum, and stay consistent.
