Using a 401(k) Loan to Pay Off Credit Cards: The Costs Nobody Lists
A 401(k) loan looks like the easiest consolidation loan there is. No credit check, the interest goes back into your own account, and the payment comes straight out of your paycheck. For some people it works. But the costs that matter are not on the loan statement. They show up if your investments would have earned more, if you leave your job, or if a payment slips.
This page covers what the IRS rules actually say, what a 401(k) loan costs compared with a personal loan and a debt management plan, and the situations where borrowing from retirement savings turns into a tax bill. IRS and Federal Reserve figures were checked on October 1, 2026. It is part of our debt consolidation guide.
Key takeaways
- Your plan does not have to offer loans. If it does, the IRS caps the loan at the lesser of $50,000 or the greater of $10,000 or 50% of your vested balance.
- Repayment must generally happen within 5 years, in substantially equal payments made at least quarterly.
- If a loan defaults, the unpaid balance is generally taxed as a distribution, and if you are under 59½, a 10% additional tax can apply.
- Leaving your job is the main danger point. If the loan is offset and not rolled over by your tax-filing deadline, it becomes taxable.
How much can you borrow from a 401(k)?
The IRS is clear that "a qualified plan may, but is not required to provide for loans." If yours does, the maximum is "(1) the greater of $10,000 or 50% of your vested account balance, or (2) $50,000, whichever is less." The IRS example: with a $40,000 account balance, the most you can borrow is $20,000.
Other IRS rules worth knowing before you ask HR:
- Repayment within 5 years, "in substantially equal payments that include principal and interest and that are paid at least quarterly." Loans for a principal residence can run longer, but that does not apply to card payoff.
- Spousal consent may be required. "A plan may require the spouse of a married participant to consent to a plan loan."
- No IRA loans. "Loans are not permitted from IRAs or from IRA-based plans such as SEPs, SARSEPs and SIMPLE IRA plans."
- Purpose does not matter. The IRS says the purpose of the loan is "irrelevant" as long as the plan provides for loans, unlike a hardship withdrawal.
- Repayments are not contributions. The IRS states that "loan repayments are not plan contributions."
401(k) loan vs personal loan vs DMP: a side-by-side comparison
| 401(k) loan | Personal loan | Debt management plan | |
|---|---|---|---|
| Credit check | Not part of the IRS rules; set by your plan | Yes | No new credit issued |
| Who gets the interest | Your own account | The lender | Your creditors, at reduced rates if they agree |
| Maximum term | Generally 5 years (IRS) | Set by the lender | 36 to 60 months (NFCC) |
| What you risk | Retirement savings and their growth; taxes if it defaults | Credit damage and collections if you default | Plan cancellation; accounts usually closed |
| If you leave your job | Balance may be offset and become taxable unless rolled over in time | No change | No change |
| Tax risk | Yes, on default (plus 10% if under 59½) | No | No |
What does a 401(k) loan cost on $15,000 of card debt?
Take $15,000 of card debt. The Federal Reserve's G.19 release of September 8, 2026 puts the average rate on credit card accounts assessed interest at 22.15% for the second quarter of 2026, and the average 24-month personal loan rate at commercial banks at 11.86%. Your plan document sets your 401(k) loan rate; we use 8.00% for illustration.
- 401(k) loan at 8.00% over 60 months: $304.15 a month, $3,249.00 in interest, paid into your own account.
- Personal loan at 11.86% over 60 months: $332.61 a month, $4,956.60 in interest, paid to the lender, before any origination fee.
Representative example. For a $5,000 loan at a 10% APR over 36 months, the monthly repayment would be $161.34. Over the term, the total repayment would amount to $5,808.24, with $808.24 in interest. The loan terms range from 6 months to 12 years, with APRs between 5.99% and 35.99%. The exact rate you receive depends on factors like your creditworthiness, loan size, and repayment schedule. Better rates are typically offered to those with excellent credit.
On these numbers the 401(k) loan looks cheaper. That comparison leaves out three costs. You can run any loan's payment yourself with the personal loan payment calculator, and test it against your current card payments with the consolidation break-even calculator.
Cost 1: what your money would have earned
While the $15,000 is lent to you, it is not invested. Your account earns the loan's interest rate on that amount instead of whatever the investments would have returned. If the investments would have done better than the loan rate, the difference is a real cost. If they would have done worse, it is not. Nobody knows which in advance, which is the point: you are swapping a known result for an unknown one, with your retirement money.
The interest itself is not free money either. You pay it from your paycheck, so it is your own cash moving into your account, not a return on your investments.
Cost 2: leaving your job with a balance
This is the cost most people miss. Plans can handle an unpaid loan by reducing your account balance, which the IRS calls a "plan loan offset." The IRS explains that if the offset happens because of plan termination or "severance from employment," you have until "the due date, including extensions, for filing the Federal income tax return for the taxable year in which the offset occurs" to roll over the offset amount. Roll it over (by putting the equivalent cash into an eligible plan or IRA) and it is not taxed. Fail to, and it is treated as a distribution.
That means a layoff can turn a $12,000 loan balance into a cash demand at the worst possible moment.
Figure: Drawn from the IRS loan FAQs and Topic 558. \*Exceptions exist, including distributions after you separate from service with your employer after reaching age 55.
Cost 3: taxes if a payment slips
The IRS says "a loan that is in default is generally treated as a taxable distribution from the plan of the entire outstanding balance of the loan," called a "deemed distribution." A plan may give you until "the end of the calendar quarter following the quarter in which the repayment was missed" before that happens.
A deemed distribution is taxed "including any early distribution tax." IRS Topic 558 sets that tax at 10% "of the portion of the distribution that's includible in gross income" for distributions before age 59½, with exceptions such as distributions after you separate from service with your employer after reaching age 55. And a deemed distribution "is not eligible to be rolled over."
A worked example, using a 22% federal bracket as an assumption. You are 40 and $12,000 of your loan becomes a taxable distribution:
| Item | Amount |
|---|---|
| Federal income tax at an assumed 22% | $2,640.00 |
| 10% additional tax (under 59½) | $1,200.00 |
| Total federal tax | $3,840.00 |
That is before any state income tax, and it lands on top of whatever caused the missed payment. The IRS does allow missed payments to be made after a deemed distribution, which increases your tax basis in the plan, but it does not undo the tax for that year.

When does a 401(k) loan make sense, and when does it not?
The CFPB's HELOC booklet, comparing ways to raise money, lists a retirement plan loan as typically allowing "up to 50% of your vested balance or $50,000, whichever is less," with your home not at risk. That is the genuine advantage over a HELOC used to pay off credit cards: it puts retirement savings at risk instead of your house.
A 401(k) loan is more defensible when:
- Your job is stable and you have no plans to leave within the loan's term.
- You can repay well inside 5 years.
- You have stopped adding to the cards. The CFPB warns that "many people don't succeed in paying off their debt by taking on more debt unless they lower their spending."
It is a poor fit when:
- Layoffs are possible, or you are job hunting.
- The card debt comes from spending that still exceeds income.
- You are behind on payments already. In that case a nonprofit counselor may get you lower rates without touching retirement savings. Compare the approaches on our debt management plan vs consolidation loan page.
Common questions
Is a 401(k) loan a good way to pay off credit card debt? It can cost less in interest than cards or a personal loan, but it puts retirement savings and their growth at risk, and it can become taxable if you leave your job or miss payments. It suits stable jobs and short payoff plans.
Does a 401(k) loan affect my credit score? IRS rules do not involve your credit report, and the CFPB's HELOC booklet describes a retirement plan loan as having "no credit check and no impact on your credit score." Your plan's own rules control; ask your administrator.
What happens to my 401(k) loan if I quit or get laid off? The plan may offset the unpaid balance against your account. You can avoid tax by rolling over the offset amount by the due date, including extensions, of your federal return for that year, per the IRS.
How long do I have to repay a 401(k) loan? Generally 5 years, with payments at least quarterly, per the IRS.
Can I borrow from my IRA instead? No. The IRS says loans are not permitted from IRAs, and borrowing from an IRA causes the account to stop being an IRA, with its full value included in income.
Can I take a second 401(k) loan? Only if your plan allows it. The IRS says the new loan plus all outstanding loans cannot exceed the plan maximum, and the $50,000 cap is reduced by how much your highest loan balance in the past 12 months exceeds your current balance.
