Federal student loan repayment rules shifted significantly when the SAVE plan launched in 2023. If you're on Income-Based Repayment (IBR), or still weighing your options, you may be wondering whether SAVE is actually better, or whether the older IBR plan is still the right fit for your situation.
Short answer: for most borrowers with graduate loans or PSLF goals, SAVE has meaningful advantages. But IBR remains the better pick in a few specific cases, and it's worth understanding why before you switch.
This guide walks through how each plan calculates your payment, who benefits most from each, and the key questions to ask before making a change. Note that federal student loan policy changes frequently. Verify current terms at studentaid.gov before acting on any of this.
How each plan calculates your monthly payment
Income-Based Repayment (IBR)
IBR sets your payment at 10% of your discretionary income if you're a new borrower (loans after July 1, 2014), or 15% if you borrowed before that date. Discretionary income under IBR is defined as your adjusted gross income above 150% of the federal poverty guideline for your household size.
After 20 years of qualifying payments (or 25 years for older borrowers), remaining balances are forgiven. That forgiven amount may be treated as taxable income under current law; check with a tax professional about your situation.
SAVE Plan (Saving on a Valuable Education)
SAVE, which replaced the older REPAYE plan, generally offers lower payments for most borrowers:
- Payments on undergraduate loans are set at 5% of discretionary income.
- Payments on graduate loans are set at 10% of discretionary income.
- Borrowers with a mix of both types pay a weighted average between 5% and 10%.
- Discretionary income is calculated using 225% of the federal poverty guideline, a more generous threshold than IBR's 150%, meaning more of your income is protected.
For borrowers with lower incomes, this can result in a $0 monthly payment that still counts toward forgiveness.
The interest subsidy difference
One of SAVE's most significant features: if your monthly payment doesn't cover the interest accruing on your loans, the government covers the difference. Your balance won't grow from unpaid interest while you're on SAVE and making required payments.
Under IBR, unpaid interest can capitalize (get added to your principal balance) in certain circumstances, which can cause your balance to grow over time even while you're making payments.
When IBR is still the right choice
There are two scenarios where IBR has a genuine edge over SAVE:
You borrowed before July 1, 2014. Older IBR borrowers pay 15% of discretionary income, which is higher than SAVE. In this case, switching to SAVE would lower your payment. But if you're among the new-IBR borrowers at 10%, the comparison is closer.
You're married and file taxes jointly. Under SAVE, your spouse's income is included in the payment calculation even if you file jointly. Under IBR, if you file separately, only your own income counts. For some couples, filing separately under IBR produces a lower payment even after accounting for the tax cost of separate filing. This is a calculation worth running with a tax professional.
SAVE and PSLF
If you're working toward Public Service Loan Forgiveness (PSLF), SAVE counts as a qualifying repayment plan. Lower monthly payments mean you'll pay less total before the 10-year forgiveness clock runs out. Since PSLF forgives whatever's left, you want to minimize how much you pay in the meantime.
IBR also qualifies for PSLF. But SAVE's lower payments and stronger interest protections generally make it the better fit for borrowers on the PSLF track with significant balances. Read more about who qualifies for PSLF in our guide to PSLF requirements and eligibility.
What about forgiveness timelines?
Under SAVE, forgiveness timelines depend on how much you originally borrowed:
- If your original balance was $12,000 or less, forgiveness comes after 10 years of payments.
- For each $1,000 above $12,000, one year is added, up to a maximum of 20 years for undergraduate loans and 25 years for graduate loans.
Under IBR, it's a flat 20 years (new borrowers) or 25 years (older borrowers), regardless of your original balance. For borrowers with smaller loan amounts, SAVE's shorter timeline can be a significant advantage.
Key questions before switching plans
Before moving from IBR to SAVE (or the reverse), think through:
- Are you married, and how does joint vs. separate filing affect your payment under each plan?
- Are you pursuing PSLF? If so, lower payments generally work in your favor.
- How much do you owe, and are you mostly undergraduate or graduate debt?
- How close are you to a forgiveness milestone on your current plan?
Switching plans can reset or complicate your progress in some cases. The studentaid.gov loan simulator is a free tool that lets you compare estimated payments and forgiveness timelines across plans using your actual loan data.
Your next step
If you have federal student loans and haven't reviewed your repayment plan recently, it's worth a few minutes in the federal loan simulator to see what your payment would be under SAVE versus your current plan.
