When Refinancing Makes Financial Sense at $100K
At $100K income, the argument for refinancing to private is stronger than at lower incomes. Key criteria: (1) rate improvement of 1%+ over current federal rate, (2) stable employment with low layoff risk, (3) no PSLF path, (4) emergency fund of 3–6 months fully funded. If all four apply: refinancing to a 5-year term at a competitive rate minimizes total interest paid.
A $60,000 student loan at federal 6.5% for 10 years: $680/month, $16,000 total interest. Refinanced to 5.0% for 7 years: $846/month, $10,700 total interest. Savings: $5,300 in interest. But you also lose federal IDR and PSLF eligibility. The math works if your income is stable and you have no PSLF path.
Aggressive Payoff vs. Refinance: The Decision Framework
- Keep federal + pay aggressively: Best if rate is below 6%, you want to preserve IDR access, or PSLF is a possibility
- Refinance + pay aggressively: Best if federal rate exceeds 6.5%, income is very stable, no PSLF path, and credit is strong (720+)
- SAVE plan + invest difference: Only makes sense if the forgiven amount significantly exceeds what you would have paid down; requires 20–25 year commitment
