Maximize Your Emergency Fund & Extra Cash
While paying off loans, don't forget to earn top rates on your emergency fund and any extra cash you're saving for loan payments. High-yield savings accounts and bank bonuses can help you earn more on money you're not putting toward debt.
How to Choose a Repayment Strategy
Smart strategies to minimize interest and pay off your student loans faster
The Student Debt Crisis
With over $1.7 trillion in outstanding student loan debt across the United States, finding the right repayment strategy has never been more important. The difference between smart and standard repayment can save you tens of thousands of dollars and years of payments.
Payment Strategies Explained
- Debt Avalanche: Pay minimums on all loans, then attack the highest interest rate loan first. Mathematically optimal for saving money.
- Debt Snowball: Pay minimums on all loans, then focus on the smallest balance first. Psychologically motivating with quick wins.
- Fixed Extra Payment: Add a consistent extra amount each month, distributed across all loans proportionally.
- Repayment Assistance Plan (RAP): The income-driven option for federal loans. Payments are based on your adjusted gross income, unpaid interest is waived, and any remaining balance is forgiven after up to 30 years of qualifying payments.
Heads up: the 2025 One Big Beautiful Bill Act eliminated the SAVE plan. New federal borrowers taking out loans on or after July 1, 2026 choose between a standard plan (fixed payments over 10-25 years, based on how much you borrowed) and RAP. If you're on SAVE, PAYE, or ICR, you'll need to move to Income-Based Repayment (IBR) or RAP by July 1, 2028.
Federal vs Private Loans
Federal Loans
- Income-based repayment options (RAP, IBR)
- Loan forgiveness programs (PSLF, etc.)
- Deferment and forbearance options
- Fixed interest rates
- Tax-deductible interest (up to $2,500 — private loans qualify too)
Private Loans
- Often variable interest rates
- Credit-based approval and rates
- Limited repayment flexibility
- Refinancing options available
- May require cosigner
When to Consider Refinancing
Refinancing can lower your interest rate, but you'll lose federal loan benefits:
Good for Refinancing:
- High-interest private loans
- Stable, high income
- Good credit score (700+)
- No need for federal protections
- Not pursuing loan forgiveness
Keep Federal Loans If:
- Pursuing Public Service Loan Forgiveness
- Income is unstable or low
- Need income-driven repayment
- Want federal deferment options
- Already have low federal rates
What's changed on this page
- August 6, 2026 Debt avalanche and debt snowball now roll a paid-off loan's minimum payment into the next loan, which is how both strategies actually work and which shortens the payoff estimate whenever you have more than one loan. The $200 extra monthly payment that was quietly applied to avalanche and snowball, without appearing anywhere in the form, is now a visible field for those strategies and no longer applies to the minimum-payments-only option. The interest deduction is now computed year by year from the real payment schedule with the $85,000-$100,000 single-filer phase-out, default federal rates moved to 6.39% undergraduate and 7.94% graduate, and the income-driven repayment section was rewritten around RAP and the 2025 OBBBA plan changes.
