How Debt Payoff Strategies Work
Monthly Interest = Current Balance × (APR ÷ 12 ÷ 100)
Principal Payment = Monthly Budget — Total Interest (applied to target debt)
Debt Avalanche: Target debt with highest APR first
Debt Snowball: Target debt with smallest balance first
Snowball Effect: When a debt is paid off, its payment amount rolls to the next debt

Debt Payoff Strategies — Which One Is Right for You?
Debt Avalanche (Mathematically Optimal)
How it works: Pay minimums on all debts, put all extra toward debt with highest interest rate.
Pros: Saves the most money on interest, mathematically optimal.
Cons: May take longer to pay off first debt if highest APR debt also has large balance (can feel discouraging).
Debt Snowball (Motivation First)
How it works: Pay minimums on all debts, put all extra toward debt with smallest balance.
Pros: Quick wins keep motivation high; studies show people are more likely to stick with snowball.
Cons: Pays more total interest than avalanche.
Frequently Asked Questions
Which debt payoff strategy is best?
For saving money: Debt Avalanche (highest APR first) — saves the most interest.
For staying motivated: Debt Snowball (smallest balance first) — quick wins keep you going.
Hybrid approach: List debts by APR, but if two have similar APRs, pay smaller balance first.
How does the snowball effect work?
When you pay off one debt, the monthly payment you were making on that debt gets added to the next debt’s payment. This “snowballs” your payment amount, accelerating payoff. Example: Paid off $100/month store card → now paying $800/month total toward next debt.
Should I include my mortgage in debt payoff?
Mortgages typically have lower interest rates (3-7%) and are tax-advantaged. Focus on high-interest consumer debt first (credit cards 15-25%, personal loans, auto loans). Consider mortgage acceleration after all other debt is gone.
What if I can’t afford the minimum payments on all debts?
If your total minimum payments exceed your monthly budget, you may need to:
– Contact creditors to negotiate lower rates or hardship plans
– Debt consolidation — combine debts into one loan with lower rate
– Credit counseling — nonprofit agencies can help negotiate
– Budget review — find areas to cut expenses
