Debt Snowball vs Avalanche: Which Method Pays Off Debt Faster?

The two methods

• Avalanche: pay the minimum on every debt, and put all extra money toward the debt with the highest interest rate. Mathematically it costs the least.
• Snowball: pay minimums on everything and attack the smallest balance first. Each payoff frees its minimum payment, which rolls into the next debt - the snowball grows.

A worked example

Say you owe $6,500 on a credit card at 24.9%, $11,000 on a car loan at 7.5% and a $1,200 medical bill with no interest, and you can add $200 a month above the minimums. With the snowball method you clear the medical bill in month 5 - a quick win. With the avalanche method the card goes first. Both plans finish in about 30 months, but avalanche saves around $317 in interest because the expensive card balance shrinks sooner.

Which should you choose?

If your debts have very different interest rates and you are disciplined, choose avalanche. If you have several small balances and need visible progress to stay motivated, snowball is a fine choice - the extra cost is often modest. The best plan is the one you will follow every month.

Speeding things up

• Call card issuers and ask for a lower APR - it works more often than people expect.
• Consider a 0% balance transfer card, but count the 3-5% transfer fee and the date the promotion ends.
• Put tax refunds, bonuses and side income straight onto the target debt.
• Stop adding new card balances while you pay down old ones.

Car and student loans

Lower-rate installment loans usually come after credit cards. For car loans, keeping the term at 60 months or less avoids owing more than the car is worth. For federal student loans, check income-driven repayment and forgiveness options before refinancing into a private loan.

Protect your progress

A small emergency fund - even $1,000 to $2,000 - stops a car repair from landing back on a credit card. Once the high-interest debt is gone, build the full fund and redirect the old debt payments into savings.
