Student Debt Strategy

Federal Loan Repayment Plans & Interest Capitalization

Understanding the mechanics of federal student loan repayment options, in-school interest accrual, and income-driven plans helps borrowers minimize total repayment costs.

Interest Capitalization

When unsubsidized loans exit grace or forbearance periods, accrued unpaid interest is added onto the principal balance (capitalization). Paying just the monthly interest during college prevents your principal from expanding.

Income-Driven Repayment (IDR)

Federal IDR plans (such as SAVE, IBR, and PAYE) cap your monthly student loan payment at 5% to 10% of your discretionary income and forgive any remaining balance after 10 to 25 years of qualifying payments.

Public Service Loan Forgiveness (PSLF)

Borrowers employed full-time by government agencies or qualifying 501(c)(3) non-profits can receive 100% tax-free loan forgiveness after making 120 qualifying monthly payments under an eligible repayment plan.
