Things to Know
Essential concepts for understanding your results
Plan ComparisonHow do federal repayment plans compare?
Standard: fixed payments over 10 years — lowest total cost, highest monthly payment. SAVE: 5% of discretionary income for undergrad, 10% for grad — lowest payments, forgiveness after 20-25 years. PAYE: 10% of discretionary income, forgiveness after 20 years. IBR: 10-15% depending on when you borrowed, forgiveness after 20-25 years. ICR: 20% or 12-year fixed adjusted — least favorable, rarely chosen.
Discretionary IncomeHow is discretionary income calculated for IDR plans?
Discretionary income = AGI minus 225% of the federal poverty line for your family size (SAVE plan) or 150% (older plans). For a single person in 2026, 225% of poverty is approximately $35,100. If AGI is $55,000, discretionary income is $19,900. SAVE plan payment: $19,900 × 5% ÷ 12 = $83/month. This is dramatically lower than the standard $550/month payment on a $50,000 loan.
Forgiveness TaxIs forgiven student loan debt taxable?
PSLF forgiveness is always tax-free. IDR forgiveness after 20-25 years was historically taxable as income — a $50,000 forgiven balance could add $10,000-15,000 in taxes. The American Rescue Plan made all student loan forgiveness tax-free through 2025. Check current law for forgiveness events after 2025. Plan for the tax possibility by building a dedicated savings fund during the final years of your repayment period.
StrategyHow do you choose the right repayment plan?
Pursuing PSLF? Use the SAVE plan for lowest payments during 10 years of qualifying service — maximizes the forgiven amount. High income, aggressive payoff? Standard or refinanced plan minimizes total interest. Moderate income, long-term? SAVE or PAYE with eventual forgiveness often costs less than standard when accounting for time value of money. Variable income? IDR plans adjust annually with your income, providing a safety net.

How Student Loan Repayment Is Calculated
Student loan repayment follows the standard amortization formula:
Monthly Payment = P × [r(1+r)^n] ÷ [(1+r)^n - 1]
Where: P = loan principal (balance), r = monthly interest rate (annual rate ÷ 12), n = total number of payments.
Example Student Loan Repayment Calculation
Scenario: $35,000 in federal student loans at 6.53% interest (the 2025-2026 undergraduate Direct Loan rate).
Standard 10-year plan: Monthly payment = $35,000 × [0.005442 × (1.005442)^120] ÷ [(1.005442)^120 - 1] = $398/month. Total paid over 10 years: $47,760. Total interest: $12,760 (36.5% of the original balance).
With $100 extra per month ($498): Paid off in 7 years, 2 months. Total interest: $9,190. Savings: $3,570 and 2 years, 10 months faster.
With $200 extra per month ($598): Paid off in 5 years, 9 months. Total interest: $7,170. Savings: $5,590 and 4+ years faster.
Income-Driven Repayment (SAVE plan at $50,000 income): Approximately $200/month. After 20-25 years: remaining balance is forgiven (but may be taxable). Total paid: approximately $48,000-$60,000 depending on income growth. The lower monthly payment provides cash flow relief but may cost more in total if income rises significantly.

Federal Student Loan Repayment Plans Compared
| Plan | Monthly Payment | Term | Total Interest on $35K | Best For |
|---|---|---|---|---|
| Standard 10-Year | $398 | 10 yrs | $12,760 | Lowest total cost |
| Graduated | $225→$600 | 10 yrs | $14,800 | Expect rising income |
| Extended Fixed | $248 | 25 yrs | $39,400 | Lower monthly payment |
| SAVE (IDR) | ~$200* | 20-25 yrs | Varies (forgiveness) | Low income / PSLF pursuit |
| IBR | ~$260* | 20-25 yrs | Varies (forgiveness) | Higher debt-to-income |
| PAYE | ~$260* | 20 yrs | Varies (forgiveness) | Newer borrowers, PSLF |
*IDR payments based on $50,000 AGI, family size of 1. Payments adjust annually with income. Department of Education data shows 57% of federal borrowers are enrolled in income-driven plans as of 2024 — up from 30% in 2019.
Key Factors That Affect Your Student Loan Repayment
Interest rate: Federal undergraduate Direct Loans (2025-2026): 6.53%. Graduate: 8.08%. Parent PLUS: 9.08%. Private loans: 4-14% depending on credit. Each 1% rate difference on $35,000 changes total interest by approximately $2,000 over 10 years. Refinancing high-rate federal loans to private (if creditworthy) can save thousands — but you lose federal protections (IDR, forgiveness, forbearance).
Repayment strategy: The standard 10-year plan minimizes total interest. Income-driven plans minimize monthly cash flow but maximize total cost (unless pursuing PSLF). Extra payments accelerate payoff dramatically — even $50/month extra saves $1,500+ in interest.
Public Service Loan Forgiveness (PSLF): After 120 qualifying payments (10 years) while working full-time for a qualifying employer (government, nonprofit), the remaining federal loan balance is forgiven tax-free. As of 2024, the Department of Education has approved $69.2 billion in PSLF forgiveness for over 946,000 borrowers. If you qualify, enrolling in the lowest IDR plan and targeting PSLF is almost always the optimal strategy — you pay the minimum for 10 years, and the rest is forgiven without tax consequences.
Tax treatment of forgiveness: PSLF forgiveness is tax-free. IDR forgiveness after 20-25 years is currently tax-free through 2025 (American Rescue Plan provision) but may become taxable after 2025 unless Congress extends the exclusion. A $50,000 taxable forgiveness event in the 22% bracket would create an $11,000 federal tax bill — still better than paying $50,000, but not free.
Student Loan Repayment Strategies: Accelerated vs Income-Driven
Accelerated payoff (best if): You earn well above your loan balance, are not pursuing PSLF, want to minimize total cost, and the psychological freedom of being debt-free matters to you. Target: pay 2-3x the minimum to clear loans in 3-5 years. Pair with the avalanche method (highest rate first) for maximum savings.
Income-driven + PSLF (best if): You work for a qualifying employer, your loan balance exceeds your annual salary, and 10 years of minimum payments + forgiveness costs less than full repayment. A borrower with $80,000 in loans at a $55,000 nonprofit salary: 10 years of SAVE payments (~$24,000 total) vs full repayment ($96,000+). PSLF saves $72,000+.
Income-driven without PSLF (caution): 20-25 years of payments that may exceed what you would have paid on the standard plan, especially if income rises. The forgiven amount may be taxable. Run the full 20-25 year projection before choosing this path — in many cases, aggressive 5-7 year payoff costs less total. Use our Student Loan vs Investing Calculator to compare.
