This student loan repayment calculator compares all repayment options, such as RAP, PAYE, IBR, PSLF, refinancing, and IDR forgiveness. It's updated with the latest 2026 federal poverty line numbers and the new definition of family size (which includes your spouse, even if you file taxes separately). If you want to model more complex scenarios, you can also download a more powerful copy of this calculator as a spreadsheet.

Note that RAP is not yet available to select as an IDR plan. We expect it to become available by July 2026.

Here are the payment plans that you can model using the student loan repayment calculator above.

  • Repayment Assistance Plan (RAP) (for comparison purposes only. Not yet available. Coming July 2026)
  • 20 Year Pay As You Earn (PAYE)
  • 20 Year New Income-Based Repayment (IBR)
  • 25 Year Old IBR
  • Refinancing
  • Standard Repayment Plan (10-year)
  • Public Service Loan Forgiveness (PSLF)

Note that not every borrower will qualify for all the listed payment plans, as eligibility depends on various factors such as borrowing date, types of loans, and more.

You can also compare PSLF with non-PSLF forgiveness options to see how factors like monthly payments, repayment terms, interest rates, and state of residence affect your total repayment.

If you want to compare Income-Contingent Repayment, check out our Parent PLUS calculator.

Estimate Your Future Monthly Payments

You know what you're paying now, but you'd probably like to know what you could be paying in five years too. You'd also like to calculate if you should refinance your student loan debt and compare tradeoffs for federal loans.

Pretend you're a resident physician making $60,000 for the next four years. You'll finish your residency in July 2026. For half the year, you'd make a resident income of $60,000, but the other half the year, you'd make an attending income of $200,000. Hence, you'd make $130,000 for this “in-between” year.


Once you become an attending, you'll earn $200,000 adjusted up for inflation. What would your monthly student loan payments be under RAP, PAYE, and IBR?

To find out, manually enter your income growth over time and instantly see how your monthly payments change.

If Refinancing is Your Best Option, Get Exclusive Cash Bonuses

After entering all your info into the student loan calculator, you'll notice different costs for the various plans. If the student loan refinancing row shows up as the cheapest option, I think there's a chance you could save a lot of money by checking out refinancing offers from private lenders.

For example, see how much you could potentially save in interest by completing a quick rate check with Splash Financial (and you get a refinancing bonus of up to $1,000 if you end up using them).

Earnest

earnest
4.5 out of 5

Earnest: Best for flexible repayment

  • Positives: Flexible repayment terms, custom loan payments
  • Allows cosigners: Yes
  • Deferment or forbearance available: Yes, up to 36 months
  • Interest rates: Fixed starting at 4.05% APR; Variable starting at 5.73% APR
  • Bonus: $200 for refinancing 50k to $99,999; $1000 for refinancing 100k or more.

Many personal finance blogs and student loan-focused websites embed referral links and take all of the referral bonuses for themselves. I think it's better for the reader and client to split it with you.

You'll get anywhere from $100-$750 AND a lower interest rate (which is the only reason to refinance student loans, of course). If you decide to refinance your loan amount after using this tool, I really appreciate it! You help me a lot by supporting this site and keeping this tool free for others.

Of course, consider the potential downsides of refinancing federal student loans before deciding.

How Does the Process Work, and What are the Companies You Suggest?

You can check your rate without affecting your credit score. Moreover, it only takes as little as a couple of minutes. I suggest checking at several companies, as you never know who will show up with the best interest rates to refinance your college costs.

If you decide to go through with the refinancing, then your score takes a temporary hit. Even so, it would be totally worth it if you cut your interest rate by 1%-3%. One time I even had a client who dropped her rate from 13% to under 3%. That result is unusual, but I see folks who save thousands in interest payments by refinancing their loans all the time. I highly suggest you consider it if you owe less than twice your income.

Want to check refinancing interest rates? Check out these awesome refinancing bonuses available to Student Loan Planner® readers and clients. You won't get them at all if you visit the lender websites directly. Additionally, it doesn't affect the interest rate they offer. So you should definitely check it out.

Frequently Asked Questions (FAQs)

How accurate is this calculator?

This calculator uses federal formulas and current poverty guidelines to provide estimates, but it may contain errors and shouldn't be relied upon for final decisions. Your actual payments may vary based on servicer calculations, recertification timing, and individual circumstances. We always recommend consulting with a student loan expert before committing to a repayment strategy.

What is RAP and how is it different from SAVE?

RAP (Repayment Assistance Plan) replaces SAVE starting July 1, 2026. The biggest changes: no more $0 payments (minimum is $10/month), payments are based on a tiered percentage of your full AGI (1-10%) rather than discretionary income, and forgiveness takes 30 years instead of 20-25. RAP does keep SAVE's interest subsidy and adds a matching principal payment of up to $50/month.

Which repayment plan will cost me the least?

It depends on your income, debt, and career path. PSLF is often cheapest for those who qualify. A RAP with 30-year forgiveness may work well for high-debt-to-income borrowers; refinancing or a Standard tends to favor higher earners. The “Present Value” column in this calculator can help you compare.

Should I refinance or stay on an IDR plan?

Consider refinancing if you have high income relative to your debt, don't qualify for PSLF, and can get a competitive rate. Staying on IDR may make more sense if you're pursuing forgiveness or value federal protections. Keep in mind that once you refinance, you permanently lose access to IDR, PSLF, and federal forgiveness.

How does filing taxes separately vs. jointly affect my payment?

RAP allows married borrowers to file separately and exclude their spouse's income from the payment calculation, which can help if your spouse earns more. However, filing separately may mean losing some tax benefits and limiting dependent deductions to kids you claim on your return. It's worth running both scenarios annually to see which might save more overall.

When should I recertify my income?

You typically must recertify annually to remain on IDR, though during the COVID pandemic, the requirement was relaxed in the past few years. Your servicer will notify you when it's due. If your income dropped, recertifying early could lower payments sooner. If it jumped, waiting until the deadline may keep your lower payment longer. Missing the deadline spikes your payment to the standard amount and can cost you forgiveness credit. See this post to learn more.

What is adjusted gross income (AGI)?

Adjusted gross income is your annual income with certain adjustments subtracted. Your prior-year AGI can be found on your Form 1040, line 11.

How do I determine family size?

Your family size is the total number of people in your family, including you, your spouse, and your children. You should also include unborn children who will be born this year.
