How to read your results

The standard 10-year plan is the default repayment option — fixed payments over 10 years. Income-driven repayment (IDR) caps your payment at roughly 10% of discretionary income (income above 150% of the poverty line), extending the term to 20-25 years — lower monthly payment, but more total interest. Refinancing with a private lender at a lower rate reduces total interest but gives up federal protections like IDR and Public Service Loan Forgiveness eligibility.

The big tradeoff with refinancing: Once you refinance federal loans with a private lender, you permanently lose access to federal protections — income-driven repayment, deferment, forbearance, and loan forgiveness programs. Only refinance if you're confident you won't need those safety nets and your income is stable.

What this calculator doesn't include

  • Public Service Loan Forgiveness (PSLF) — if you work for a qualifying employer, IDR + PSLF can result in forgiveness after 120 payments, which could be dramatically cheaper than any option shown here.
  • Income changes over time — IDR payments adjust annually based on income; this calculator uses your current income throughout.
  • Tax implications of forgiveness — under current law, forgiven IDR balances are not taxed federally through 2025; verify current rules.
  • Multiple loans with different rates — if you have several loans, refinancing can consolidate them into a single new rate.

Who should consider each path

Choose standard if you want loans paid off fastest and can afford the payment. Choose income-driven if you're in a lower-paying field, especially public service, or need payment flexibility. Choose refinancing if you have strong, stable income, won't need federal protections, and want to minimize total interest paid.
