Short answer: no. For nearly every federal student loan borrower, wage garnishment and the rest of the default collections process will cost more than the lowest-payment repayment plan they qualify for. There is one structurally interesting exception, but even that one comes with consequences that ruin any savings.

Still, the question gets asked — usually by borrowers who feel cornered, see a $0 IBR payment as suspicious, or assume default is “free” until collectors find them. Here is how the math actually works.

What Student Loan Default Collections Actually Takes From You

Once a federal student loan defaults, the Department of Education has three main tools:

• Administrative wage garnishment (AWG): up to 15% of disposable pay, after a protected amount equal to 30 times the federal minimum wage per week (roughly $290/week).
• Treasury Offset Program: seizes federal tax refunds, certain federal benefits, and (for many borrowers) state tax refunds.
• Social Security offset: up to 15% of benefits, with a $750/month protected floor. This restarted under current Treasury enforcement after a pause.

Federal salary offset can also apply to government employees.

Collection fees also ran as high as 20% of the balance, and interest continues to accrue. The result is that the money that is “taken” from you rarely makes it towards your student loan balance. You effectively get into a “death spiral” of having money taken for no benefit – or even a growing loan balance.

If a borrower has no W-2 wages, no tax refund, no Social Security check, and no federal paycheck, default collections can technically take $0 in a given year. That is where the “is default cheaper?” question starts.

What Student Loan Repayment Costs

The two relevant comparison points right now are RAP (the new Repayment Assistance Plan) and IBR.

• RAP has a $10/month minimum payment regardless of income. It scales up to 10% of AGI at higher incomes, and because it is AGI-based, it captures self-employment income, rental income, capital gains, and K-1 distributions.
• IBR calculates payments off discretionary income (AGI minus 150% of the federal poverty line). If discretionary income is zero or negative, the payment is $0. Otherwise it is 10% or 15% of discretionary income depending on the borrower’s IBR cohort.

For low-income borrowers, IBR can produce a genuine $0 monthly payment with no minimum floor. but generally, 10% of your AGI or discretionary income will be less than the 15% taken from you during AWG along with your tax refund offsets.

When Default Math “Looks Better” But Really Isn’t

There are a few cases where the raw monthly cost of default is lower than RAP:

1. A borrower with no garnishable wages and no tax refund. AWG = $0. Treasury Offset = $0. RAP still wants $10/month. IBR is at $0. But in this case, a $0 IBR is better than garnishment.
2. A borrower whose W-2 disposable pay sits under the 30x minimum wage protection. AWG cannot touch it. RAP still wants $10/month. IBR is $0. Again, $0 IBR is better.
3. A self-employed borrower who manages estimated taxes precisely. No refund to seize, no W-2 to garnish. Default takes very little. However, if the government gets wind of this, there are still other methods like levying your bank accounts.

The Actual Wage Garnishment Isn’t The Only Concern

Cash flow (or reduced cash flow due to AWG) is not the only cost. Default carries:

• Collection fees (up to 20%) and interest capitalization.
• Loss of all forgiveness credit – time in default doesn’t count for PSLF or time-based loan forgiveness.
• Credit damage that raises the price of renting, car loans, car insurance, utility deposits, and even bank account approval.
• Loss of access to further federal student aid.
• Professional license risk in some states.
• Treasury Offset reaching items borrowers forget about such as state refunds, certain federal benefits.

Current enforcement is also more aggressive than the pre-2020 baseline. Social Security offsets are back. 

The key to remember that your entire financial life is more expensive as the result of the default. So while you may not think about the AWG, you will face higher costs elsewhere as well.

Bottom Line

In pure monthly cash flow terms, default can look cheaper for borrowers with no garnishable wages and no tax refunds. Once collection costs and fees, lost time to loan forgiveness, and the price of damaged credit get added in, IBR at $0 wins the low-income scenario, and RAP or IBR beats default for anyone with meaningful AGI.

Default is not a repayment strategy. It is a costly penalty box.
