Rate Hike Could Speed Balance Growth for Income-Driven Student Loan Repayment Plans

Recent increases in the interest rates for new federal student loans—and the possibility of additional hikes—could result in borrowers experiencing higher payment amounts and facing greater difficulties in paying down balances, depending on their income and the repayment plan they choose.

The U.S. Department of Education announced this spring that interest rates for new loans would increase for the next academic year. Interest rates for new federal student loans are determined annually and fixed for the life of the loan, using a formula stipulated by federal law, with a limit of 8.25% for undergraduates. With the Federal Reserve increasing its benchmark rate throughout 2022 in response to inflation concerns, student loan interest rates will continue to rise accordingly.

New federal undergraduate loans now carry a 4.99% interest rate—a sizable increase over last year’s 3.73%. The interest rate for new graduate and parent loans similarly has risen; it now stands at 6.28% over the previous year’s 5.30%. New borrowers who enroll in the standard repayment plan may see higher payments than they would have on the same balance at a lower interest rate, but these increases could create other problems for borrowers enrolled in income-driven repayment (IDR) plans.

The IDR plans tie monthly payments to borrowers’ income and allow unpaid balances to be forgiven after 240 or 300 months of qualifying payments. About 30% of all student loan borrowers are currently enrolled in IDR plans, which tend to have lower payments and lower default rates than the standard 10-year repayment plan.

A Pew analysis finds that borrowers enrolled in IDR plans could experience accelerated balance growth, depending on whether their monthly payment amount covers the interest that accrues each month. Borrowers should not see increases in their monthly payments, but any increase in the principal balance of their loans could further discourage borrowers who have previously reported feeling frustrated about ballooning balances in their IDR plans.

Last year, in an effort to estimate the impact of a higher interest rate on IDR repayment, Pew created an “example borrower” with common characteristics a bachelor’s degree with estimated median income, debt, and annual increases in income. Referenced in a submission to the Department of Education, the median borrower with a bachelor’s degree has an annual income of $33,405 along with $27,265 in debt at the start of repayment, and, for the purposes of this analysis, is assumed to not miss any payments throughout repayment. Research has found that many borrowers of all types miss payments at different points. Interest then can capitalize during these and other repayment disruptions, further accelerating balance growth.

The repayment outcomes for this borrower at each respective interest rate indicate that new borrowers who choose to enroll in IDR will make less progress toward paying down their principal balance than IDR borrowers repaying loans with a lower rate (see table below).

Repayment outcomes for undergraduate borrowers using previous and new interest rates

Repayment outcomes Previous 3.73% interest rate New 4.99% interest rate 3.73% vs. 4.99%
Lowest monthly payment $119 $119 No Change
Highest monthly payment $194 $194 No Change
Total amount paid $36,831 $36,831 No Change
Principal $22,184 $12,690 -$9,495
Interest $14,647 $24,141 $9,495
Remaining forgivable balance $5,606 $15,319 $9,712
Repayment period 240 240 No Change

Note: The 4.99% interest rate went into effect in July 2022 and will be applied to new undergraduate loans until June 30, 2023. At that point, a new interest rate will go into effect for new loans.

Because of the interest rate hike, the example borrower would have a significantly higher share of monthly payments applied to interest rather than principal. Although the regular payment amounts do not change, as the borrower’s income is the same in both scenarios, the higher interest rate means that unpaid interest accrues more quickly with the 4.99% rate. That leads to nearly $10,000 more going toward interest rather than principal over the twenty years they spend in repayment. Each month, IDR borrowers would make less progress toward paying down their balance. The end result would be a significant increase in balance growth that could prove discouraging to borrowers’ long-term repayment efforts.

With more interest rate hikes potentially on the horizon, policymakers should consider making changes to income-driven plans to protect low- and median-income borrowers from the impact and prevalence of balance growth. Although higher interest rates would spur additional balance growth, even current levels of growth have proven troublesome for some borrowers in IDR plans.

Balance growth in IDR plans is largely the result of their design—lowering monthly payments and extending repayment periods cause interest to accrue when payments are less than the monthly accrued interest. Despite the prospect of forgiveness after 20 or 25 years of repayment, growing balances can overwhelm borrowers and cause them to disengage from the repayment system, according to research done by Pew. Disengagement can lead to missed payments, which could result in borrowers losing eligibility for their IDR plans or otherwise delaying forgiveness. As the department considers creation of a new IDR plan, Pew recommends several steps to address these concerns. The government should:

  • Expand interest subsidies. In addition to subsidizing the unpaid interest of borrowers who make $0 payments—those with incomes below 150% of the federal poverty level guidelines—future IDR plans should expand interest subsidies to payments above this amount. Expanding interest subsidies to more borrowers—in full or in part—would help mitigate the negative effects of mushrooming loan balances.
  • Examine whether “incremental” forgiveness is administratively feasible. Recent reports have identified significant problems related to how loan servicers track qualifying payments by IDR borrowers and their progress toward forgiveness—as well as how the Department of Education manages this process. The department has announced a series of policies to address these concerns, but congressional oversight and action will be needed to ensure that they are implemented in a timely manner. In addition, administrative or legislative changes to IDR plan design could help keep mistakes from recurring. Forgiving a portion of loan balances at intervals earlier than the current thresholds might incentivize borrowers to remain in repayment and could act as an ongoing audit to ensure payments are accurately and regularly counted.
  • Permanently exempt forgiven debt from being taxed as income. As can be seen in the table above, higher rates of unpaid interest accrual will lead to increases in the amount of projected loan forgiveness, which has historically been treated as taxable income for borrowers. Although the American Rescue Plan exempts forgiven balances from counting as taxable income through December 2025, a more permanent change is needed. Many borrowers who reach the forgiveness threshold have low incomes relative to their debt, meaning that affording the tax liability resulting from a forgiven balance could be a financial hardship. This change would require action from Congress to be implemented.

A period of rising student loan interest rates should spur policymakers to address balance growth through evidence-based policy reforms. Income-driven repayment helps many borrowers avoid delinquency and default, and federal student loans offer more protections and, often, lower interest rates than their private counterparts. By taking action to limit balance growth, the Department of Education can help ensure that borrowers are able to sustainably pay down their loans.

Student Loan Repayment Proposal Improves but Could Be Better

Quick View
Speeches & Testimony

A new federal proposal to help Americans repay their student loans would make repayments more affordable for many borrowers but should be improved to better benefit those most at risk of delinquency and default. That’s what The Pew Charitable Trusts found when it modeled scenarios of how the proposed Expanded Income-Contingent Repayment (EICR) plan would affect repayments compared with an existing plan, the Revised Pay As You Earn (REPAYE) program. Both the proposed and existing programs are income-driven repayment plans, which tie monthly payments to the borrower’s income.
