Student Loan Repayment Strategies: Avalanche, Snowball, and SAVE Plan
Three approaches to paying off student loans. One saves the most money. One keeps you motivated. One lowers your payments.

This page compares three repayment frameworks: avalanche, snowball, and income-driven (SAVE). For extra-payment tactics and refinance/side-hustle ideas, use Student Loan Payoff Hacks.
The Numbers
A $37,000 federal student loan at 6.5% on the standard 10-year plan is roughly $420/month and about $13,500 in total interest. Your actual payment depends on your balance, rate, and plan.
Strategy 1: Avalanche Method (Saves the Most Money)
List all loans by interest rate, highest to lowest. Pay minimums on all loans except the highest-rate loan. Throw every extra dollar at the highest-rate loan until it is paid off. Move to the next highest rate.
Pros: Mathematically optimal. Minimizes total interest paid. Cons: If your highest-rate loan is also your largest, progress feels slow early on.

Strategy 2: Snowball Method (Best for Motivation)
List all loans by balance, smallest to largest. Pay minimums on all loans except the smallest balance. Throw every extra dollar at the smallest loan until it is paid off. Move to the next smallest.

Pros: Quick wins build momentum and motivation. Psychologically powerful. Cons: You pay more total interest because you may ignore higher-rate loans.
Strategy 3: SAVE Plan (Income-Driven Repayment)
The Saving on a Valuable Education plan caps payments at 5% of discretionary income for undergraduate loans (10% for graduate). After 20 years of payments (10 for balances under $12,000), any remaining balance is forgiven.
Best for: Borrowers with high debt relative to income, those pursuing Public Service Loan Forgiveness, or those who need lower monthly payments.
The Decision Framework
- High income, want to be debt-free fast: Avalanche method.
- Need motivation and quick wins: Snowball method.
- Low income relative to debt, or pursuing PSLF: SAVE plan.
- Mixed approach: Use the snowball method to eliminate one or two small loans for psychological wins, then switch to avalanche for the remaining loans.
One Universal Rule
Never pay only the minimum on the standard plan if you can afford more. Every extra dollar reduces principal, which reduces future interest. Even $50/month extra on a $37,000 loan at 6.5% saves $3,200 in interest and pays the loan off 2 years early.
