Student Loan Repayment Strategies

1. The Avalanche Method (Mathematically Optimal)

Strategy: Pay minimums on all loans, then put extra payments toward the loan with the highest interest rate.

Benefits:

Saves the most money on interest
Pays off debt fastest
Mathematically optimal approach
Reduces total cost of debt

Example:

Loan A: $20,000 at 6.8% (minimum: $230)
Loan B: $15,000 at 4.5% (minimum: $170)
Loan C: $10,000 at 3.5% (minimum: $115)
Extra payment: $300/month

Payoff Order: Loan A → Loan B → Loan C

2. The Snowball Method (Psychologically Motivating)

Strategy: Pay minimums on all loans, then put extra payments toward the loan with the smallest balance.

Benefits:

Provides quick wins and motivation
Builds momentum and confidence
Easier to stick with long-term
Creates positive reinforcement

Example (same loans as above): Payoff Order: Loan C → Loan B → Loan A

3. The Hybrid Method (Balanced Approach)

Strategy: Combine elements of both methods based on your situation.

Approach:

Start with snowball method for quick wins
Switch to avalanche method once motivated
Adjust based on changing circumstances
Balance psychology with mathematics
