Marcus — New grad, public service career
Marcus graduated with $42,000 in Direct Unsubsidized loans at 6.39%. He earns $52,000 as a city government employee (PSLF-qualifying). Under Standard 10-year, his payment is $468/month and total paid is $56,160.
Under IBR New (10% of discretionary income, family size 1), his payment drops to $234/month. After 120 PSLF-qualifying payments his remaining balance — approximately $28,000 — is forgiven completely tax-free. Total out-of-pocket: $28,080 vs. $56,160 on Standard.
Takeaway: PSLF is worth $28,000+ for Marcus. Refinancing would forfeit the entire tax-free forgiveness for a $40/month interest saving — a catastrophic trade.
