How Student Loan Repayment Works
Federal student loans use a standard amortization formula: each monthly payment covers accrued interest plus reduces principal. On the Standard Repayment Plan, you pay equal amounts over 10 years. Income-driven plans (SAVE, IBR, PAYE) cap payments at 5–10% of discretionary income and forgive remaining balances after 20–25 years. PSLF forgives after 10 years for qualifying public service employees.
Standard Plan
Fixed payments over 10 years. Highest monthly payment but lowest total interest — you pay off faster.
Income-Driven
SAVE, IBR, PAYE plans cap payments at 5–10% of discretionary income. Balance forgiven after 20–25 years.
PSLF
Public Service Loan Forgiveness: 120 payments on income-driven plan while working for qualifying employer. Tax-free forgiveness.
