Calculate your monthly payment and total interest. Compare every federal repayment plan side by side, Standard, IBR, PAYE, SAVE, and PSLF. Analyze refinancing with break-even analysis.
Compare all major federal repayment plans for your loan. Income-driven plans cap payments as a percentage of discretionary income, unused balances may be forgiven after 20–25 years (taxable) or 10 years under PSLF (tax-free).
⚠️ Federal loan warning: Refinancing federal loans into private loans permanently loses access to income-driven repayment, PSLF, deferment, and forbearance. Only refinance federal loans if you're confident you won't need those protections.
If you have federal loans and a lower income relative to your balance, income-driven repayment (IDR) can be transformative. The SAVE plan caps payments at 5-10% of discretionary income and forgives balances after 20-25 years. For someone with $80,000 in loans earning $50,000, standard repayment might be $850/month, SAVE might be $200. Run both scenarios before defaulting to standard repayment.
Federal student loans come with a repayment ecosystem unlike any other form of debt in the United States. Unlike mortgages, auto loans, or personal loans, which offer a single standard repayment structure, federal student loans offer eight distinct repayment plans, income-driven forgiveness pathways, Public Service Loan Forgiveness, deferment and forbearance protections, and temporary adjustment programs. Understanding how these options interact is essential to making the optimal repayment decision for your situation. The difference between choosing the right plan and defaulting to the Standard plan can mean tens of thousands of dollars in unnecessary interest, or, for PSLF-eligible borrowers, six figures in forgiven balances.
Every federal loan borrower is automatically enrolled in the Standard Repayment Plan unless they actively request an alternative. Standard repayment divides the loan into equal monthly payments over 10 years (120 payments). It produces the lowest total interest cost of any repayment plan and results in the loan being fully paid off at the end of the term with no forgiveness component. For borrowers whose monthly payment is manageable relative to their income, staying on the Standard plan is often the mathematically optimal choice, unless they qualify for PSLF, in which case maximizing forgiveness by minimizing payments is the better strategy.
Income-Driven Repayment (IDR) plans cap monthly payments at a percentage of your discretionary income, the portion of your income above a poverty line threshold (typically 150% of the federal poverty guideline for your family size). There are four active IDR plans in 2025, each with different payment percentages and forgiveness timelines:
| Family Size | 100% Poverty | 150% Poverty | 225% Poverty (SAVE) |
|---|---|---|---|
| 1 | $15,060 | $22,590 | $33,885 |
| 2 | $20,440 | $30,660 | $45,990 |
| 3 | $25,820 | $38,730 | $58,095 |
| 4 | $31,200 | $46,800 | $70,200 |
| 5 | $36,580 | $54,870 | $82,305 |
PSLF is a federal program that forgives the remaining balance on Direct Loans after 120 qualifying monthly payments (10 years) while working full-time for a qualifying employer, government agencies, 501(c)(3) non-profits, and certain other public service organizations. Crucially, PSLF forgiveness is tax-free, unlike standard IDR forgiveness which is currently treated as taxable income. For borrowers with large loan balances and modest incomes in eligible jobs, PSLF can result in forgiveness of $50,000 to $200,000+ after 10 years of reduced IDR payments, a financially transformative outcome. The strategy: enroll in an IDR plan to minimize payments, make exactly 120 qualifying payments while employed in a qualifying role, then receive forgiveness of any remaining balance. Payments don't need to be consecutive. The Employment Certification Form (now called the PSLF Form) should be submitted annually and whenever you change employers to track qualifying payments.
Private student loan refinancing replaces one or more existing loans (federal or private) with a new private loan at a potentially lower interest rate. For borrowers with strong credit (typically 700+ FICO), stable income, and loans with high interest rates, refinancing can meaningfully reduce total interest paid. The critical consideration: refinancing federal loans into private loans is irreversible and permanently eliminates access to all federal protections, IDR plans, PSLF, federal deferment, forbearance, and income-driven forgiveness. The break-even analysis in the Refinance tab shows how long it takes monthly savings to offset any upfront fees. As a rule of thumb, refinancing makes most sense when you have stable income, don't plan to pursue PSLF, can get a rate at least 1–2 percentage points lower, and plan to hold the loan past the break-even period.

Doctors, lawyers, teachers, social workers, and government employees with significant federal loan balances and modest-to-moderate starting incomes are often ideal PSLF candidates. A physician completing residency with $200,000 in federal loans might make low IDR payments during a $60,000 residency salary for years 1–4, then make somewhat higher payments during attending years, and have a substantial balance forgiven tax-free after 120 total qualifying payments. The math often results in paying substantially less than the original loan balance while receiving six-figure forgiveness. The requirement is qualifying employment, not low income throughout, a physician in a non-profit hospital qualifies at any income level.
For borrowers with manageable balances (under $50,000) headed into well-paying private sector careers, the Standard 10-year plan with extra payments often produces the best outcome. The faster payoff eliminates interest and the psychological burden of debt. If your income exceeds your loan balance, IDR plans may not provide meaningful payment reduction and you'd simply pay more interest over a longer timeline. Run the numbers: if your standard monthly payment is 10–15% of gross income, the standard plan is typically worth staying with.
For borrowers whose Standard payment would exceed 10–15% of take-home pay, IDR plans provide essential breathing room. The SAVE plan in particular has an interest subsidy provision: if your payment doesn't cover all monthly interest, the government covers the difference, meaning your balance never grows due to unpaid interest. This protection prevents the balance from ballooning while income is low, which was a common trap under older plans.
