Social Security Student Loan Offset Calculator

What is a Social Security offset?

A Social Security offset is when the federal government withholds part of your monthly benefit to repay a debt you owe to a federal agency — in this case, a defaulted federal student loan. It runs through the U.S. Treasury’s Treasury Offset Program (TOP), not through a court, and only one type of debt at a time is relevant here: federal student loans. Private student loans can never reach your Social Security.

Your loans only become eligible for this after they fall into default. Federal student loans enter default after about 270 days of missed payments and move into the Department of Education’s collections program at roughly 360 days. If you are current, in deferment, in forbearance, or making payments under a plan, your benefits are not at risk.

How the math works

The government does not simply take 15% of your check. By law, the offset is the lesser of two amounts, and your monthly benefit can never be reduced below $750:

• 15% of your total monthly benefit, or
• The amount of your benefit that exceeds the $750 protected floor

The offset equals the smaller of 15% of your benefit or the amount above $750 — whichever leaves you with more money.

The 15% is calculated from your total benefit before deductions such as your Medicare premium. Here is how that plays out at three benefit levels:

Monthly benefit	15% of benefit	Amount above $750	Actual offset
$700	$105	$0	$0
$850	$128	$100	$100
$1,500	$225	$750	$225

At $700, the entire check is protected because it does not exceed the $750 floor. At $850, the amount above the floor ($100) is smaller than 15% ($128), so only $100 is taken. At $1,500, the 15% figure ($225) is the smaller of the two, so that is the cap.

Which benefits are protected?

This is where most people are caught off guard. “Disability” and “welfare” are not single categories — and they split in ways that surprise people. SSI and welfare are safe, but SSDI, which many people simply call “disability,” can be offset.

SSI (Supplemental Security Income) is needs-based and fully protected. SSDI (Social Security Disability Insurance) is an earned insurance benefit, so it is treated like retirement income and can be offset under the same 15% cap and $750 floor. The one upside for SSDI recipients: you may qualify to have the loan discharged entirely (see below).

Who this affects

Older borrowers make up a fast-growing share of student loan debt. About 2.9 million people age 62 and older held federal student loans as of early 2025 — a 71% increase since 2017. More than 450,000 borrowers in that age group are in default and likely receiving Social Security, which puts a large group of retirees and people on fixed incomes directly in the path of these offsets.

The notice you should receive

Before an offset begins, the U.S. Treasury is supposed to mail a notice to your last-known address stating that the offset and negative credit reporting are scheduled to begin in 65 days. That notice may be sent only once, and offsets continue until the debt is paid or the default is resolved. A more detailed second notice should arrive at least 30 days before a Social Security offset, listing the amount and the agency to contact.

What you can do

An offset is not permanent, and getting your loans out of default stops it. You generally have four routes:

1. Loan rehabilitation. Make nine on-time, voluntary payments across 10 consecutive months. The payment is set at 15% of your annual discretionary income, divided by 12, so it is tied to what you can afford. Rehabilitation can be used once per loan and removes the default from your credit report.
2. Loan consolidation. Roll your defaulted loan into a new Direct Consolidation Loan by either agreeing to an income-driven repayment plan or making three consecutive on-time payments first. This ends default faster than rehabilitation, but the default stays on your credit report.
3. Total and Permanent Disability (TPD) discharge. If you receive SSDI, you may qualify to have the loan cancelled entirely. You apply on StudentAid.gov, there is no longer a post-discharge income-monitoring period, and the Department of Education sometimes cancels loans automatically through a data match with the SSA or VA.
4. Hardship reduction. Under the Debt Collection Improvement Act, the Department of Education can reduce or eliminate an offset that would cause financial hardship. There is a specific form for Social Security offset hardship requests.
