Quick answer
The cheapest way to repay student loans is the standard 10-year plan or an aggressive payoff. Income-driven repayment lowers monthly payments based on income, PSLF forgives federal loans after 10 years of public service work, and refinancing can cut rates for borrowers with strong credit — but ends federal protections.
Americans hold over $1.7 trillion in student loan debt, with the average borrower owing approximately $37,000. Choosing the right repayment strategy can save you thousands — or even lead to complete loan forgiveness. Here's a breakdown of your options.
Standard Repayment (10-Year Plan)
The default federal plan splits your balance into 120 equal monthly payments over 10 years. This is the fastest and cheapest way to pay off federal loans — you'll pay the least total interest. But the monthly payments can be high.
Example: $37,000 at 5.5% = $401/month for 10 years, $11,150 total interest.
Income-Driven Repayment (IDR) Plans
IDR plans cap your monthly payment based on income and family size. After 20–25 years of payments, any remaining balance is forgiven (though forgiven amounts may be taxable).
SAVE Plan (Newest, Most Generous)
- Payments capped at 5% of discretionary income for undergraduate loans
- Interest doesn't capitalize when payments don't cover it
- Forgiveness after 20 years (undergraduate) or 25 years (graduate)
- Best for: Low-to-moderate income borrowers with high debt relative to income
When IDR Makes Sense:
- Your student loan debt exceeds your annual income
- You work in public service (pair with PSLF — see below)
- You need lower payments now and expect income to grow later
Public Service Loan Forgiveness (PSLF)
PSLF forgives your remaining federal loan balance after 120 qualifying payments (10 years) while working for a qualifying employer — government agencies, nonprofits, or certain other public service organizations.
Key Requirements:
- Work full-time for a qualifying employer
- Have Direct Loans (consolidate if you have FFEL or Perkins loans)
- Be on an IDR plan
- Make 120 qualifying payments (don't need to be consecutive)
PSLF forgiveness is tax-free, unlike IDR forgiveness. If you qualify, this is potentially the best deal available.
Refinancing
Refinancing replaces your loans with a new private loan at a (hopefully) lower interest rate. This can save thousands in interest if you have strong credit and stable income.
When to Refinance:
- You have good credit (700+) and stable income
- Your current rates are above market rates
- You don't need IDR or PSLF protections
- You have private loans (no federal benefits to lose)
When NOT to Refinance:
- You're pursuing PSLF (refinancing makes federal loans ineligible)
- You might need income-driven repayment in the future
- Your income is unstable (you lose federal forbearance protections)
Aggressive Payoff Strategy
If you want to be debt-free fast, use the Avalanche method — target the highest-interest loan first while making minimums on the rest. Use our Debt Payoff Calculator to create a custom payoff timeline for all your student loans.
Which Strategy Is Right for You?
- High income, low debt: Standard 10-year plan or aggressive payoff
- Low income, high debt: IDR plan (SAVE or PAYE)
- Public service career: IDR + PSLF
- Good credit, private loans: Refinance for lower rate
- Mixed situation: Keep federal loans on IDR, refinance private loans

Frequently Asked Questions
What is Public Service Loan Forgiveness (PSLF)?
PSLF forgives your remaining federal student loan balance after 120 qualifying payments (10 years) while working full-time for a government agency or qualifying nonprofit.
Should I refinance my federal student loans?
Only if you have strong credit, stable income and don't need federal benefits. Refinancing into a private loan permanently gives up income-driven repayment, forgiveness programs and federal forbearance options.
