Borrowers with federal student loans can choose an income-driven repayment (IDR) with payments that are capped at a set percentage of their income. These loans provide loan forgiveness for any balances left at the end of repayment.

There are several types of income-driven plans, and each of them can make monthly federal student loan payments much more affordable. But income-driven repayment plans can result in higher interest costs over time in some cases.

This guide will explain the basics of how these plans work and provide details on how you calculate your income to determine your monthly IDR payment.

Note

On Aug. 24, 2022, President Joe Biden’s administration proposed a new plan for federal student loan repayment for undergraduate loans. The plan would cap monthly payments at 5% of your monthly income. After 10 years, whatever remaining balance you have would be eliminated if the original loan balance was $12,000 or less.

Loans During COVID-19

Most borrowers with federal student loans, including those on an IDR program, do not have to make payments during the coronavirus crisis.

The Secretary of Education temporarily suspended federally owned student loan payments and interest from March 13, 2020, through Jan. 31, 2022. The date was extended until Aug. 31, 2022. It was then extended again to Dec. 31, 2022, and then again into 2023.

Note

On Tuesday, Nov. 22, 2022, the Biden administration extended the pause on payments and interest on federal student loans for the eighth time. Borrowers with federal student loans won’t have to make payments, and loans won’t resume accumulating interest, until 60 days after court cases challenging Biden’s student loan forgiveness program are resolved or the Department of Education is allowed to move forward with the program. If the cases aren’t resolved by June 30, 2023, payments will resume two months after that.

The period during which loan payments are suspended will count toward earning loan forgiveness under income-driven plans and under Public Service Loan Forgiveness (PSLF).

What Is an Income-Driven Repayment Plan?

IDR plans are designed to make paying off student loans affordable based on your wages and the size of your family. There are four different IDR options that you can choose from if you have eligible federal student loans:

  • Revised Pay as You Earn (REPAYE): Payments are generally set at 10% of your discretionary income. Any remaining balance from undergraduate study is forgiven after 20 years. The limit is 25 years if any loans were taken out for graduate or professional programs. 
  • Pay as You Earn (PAYE): Payments are generally set at 10% of discretionary income, but they can't exceed the amount you'd owe under the standard repayment plan. Any remaining balance is forgiven after 20 years of payments. 
  • Income-Based Repayment (IBR): Payments are generally set at 10% of discretionary income if you first borrowed after July 1, 2014, or at 15% of income if you borrowed prior to that date. Payments can never exceed the amount you'd owe under the standard 10-year repayment plan. Any remaining balance is forgiven after 20 years for borrowers who took their loans after July 1, 2014, or after 25 years for other borrowers. 
  • Income-Contingent Repayment (ICR): Payments are set at the lesser of 20% of discretionary income or the amount that would be due if you had a 12-year repayment plan with a fixed payment, adjusted for income. Any remaining balance is forgiven after 25 years of payments. 

Note

Student loan debt that's forgiven or discharged between 2021 and 2025 is tax-free due to the American Rescue Plan Act of 2021.

How Do You Calculate Income for an Income-Driven Plan? 

There are just a few simple steps involved in calculating your income for income-driven repayment.

Determine Your Annual Income

This is your income from all sources throughout the year. It includes all taxable income from employment, unemployment benefits, dividends, alimony, and interest. It does not include untaxed income, such as public benefits from your state or Supplemental Security Income

You can find your annual income on your tax returns. But you may need to provide additional documentation if your income changed significantly compared to the previous year.

Note

On Aug. 24, 2022, President Joe Biden announced via Twitter the cancellation of $10,000 of federal student loan debt for eligible borrowers, and $20,000 for federal Pell Grant recipients.

Determine Whether Your Spouse's Income Counts

Both your income and your spouse's earnings count when determining your income if you're married and file a joint tax return. Generally, only your income counts if you're married and file a separate return. Your spouse's income must be factored under the REPAYE Program unless you can't access information about their income for some reason or you're separated. 

Note

Your monthly payments could rise substantially after marriage if your spouse has higher earnings than you or doesn't bring much student loan debt into the marriage. 

Determine Your Family Size

Your family size is the number of people in your family, including anyone who lives with you and receives more than half their support from you, including children and dependent adults.

Determine the Poverty Guideline for Your Family Size and Location

The Department of Education uses poverty guidelines from the Department of Health and Human Services to calculate your discretionary income. The 2022 guidelines are:

Number of People in Household 48 States & DC Alaska Hawaii
One $13,590 $16,990 $15,630
Two $18,310 $22,890 $21,060
Three $23,030 $28,790 $26,490
Four $27,750 $34,690 $31,920
Five $32,470 $40,590 $37,350
Six $37,190 $46,490 $42,780
Seven $41,910 $52,390 $48,210
Eight $46,630 $58,290 $53,640
For more than eight, add this amount for each additional person $4,720 $5,900 $5,430

Calculate Your Discretionary Income

Calculate your discretionary income by taking the difference between your annual income and 150% of the poverty guideline for your location and family size if you're on the PAYE plan, IBR plan, or if your loan is in rehabilitation.

Your discretionary income is calculated by taking the difference between your annual income and 100% of the poverty guideline if you're on the ICR plan.

Your payments will equal either 10% or 15% of your discretionary income, depending on your IDR plan. 

Note

The easiest way to calculate your monthly payment under an income-driven plan and other student loan payment plans is to use the loan simulator made available by Federal Student Aid. 

Factors for Married Couples to Consider

The Department of Education will determine eligibility for IDR plans based on your combined income if you file a tax return jointly with your spouse. It will also take combined student loan debt into consideration. Getting married and filing a joint tax return could have a big impact on your monthly student loan payment.  

Married filing separately can keep student loan payments lower under some circumstances, but this filing status has other consequences. It may make sense to talk with a tax expert about what filing option makes sense.
