401(k) Loans: How They Work, Rates, and Repayment Rules

A 401(k) loan lets you borrow money from your own retirement savings, typically up to $50,000 or 50% of your vested balance, whichever is less. You repay the loan through payroll deductions, and the interest you pay goes back into your own account.

Unlike traditional loans, 401(k) loans don't require a credit check, won't show up on your credit report, and generally have lower interest rates than personal loans or credit cards. But borrowing from your retirement account comes with real risks, including lost investment growth and potential tax penalties if things go wrong.

What Is a 401(k) Loan?

A 401(k) loan is a loan you take out against your vested balance in an employer-sponsored 401(k) retirement plan. The money comes from your own contributions and any vested employer match, and you pay it back with interest over a set period.

Not all 401(k) plans allow loans. According to the Bureau of Labor Statistics, roughly 86% of 401(k) plans with more than 100 participants offer a loan provision. Your plan documents will specify whether borrowing is available and under what terms.

The IRS sets the borrowing limits and repayment rules, but your employer's plan may impose additional restrictions. Some plans limit the number of outstanding loans, require a minimum loan amount, or restrict the purposes for which you can borrow.

How Does a 401(k) Loan Work?

When you take a 401(k) loan, the money is withdrawn from your retirement account and deposited into your bank account, usually within a few business days. You then repay the loan through automatic payroll deductions that include both principal and interest.

Here's the basic process:

1. Check your plan's loan provisions. Contact your plan administrator or log into your retirement account to confirm loans are allowed and review the terms.

2. Submit your loan request. Most plans let you apply online through the plan's website. You'll choose a loan amount and repayment term.

3. Receive the funds. Once approved, the money is typically deposited into your bank account within a few business days.

4. Repay through payroll deductions. Payments are automatically deducted from your paycheck on each pay period. Both principal and interest flow back into your 401(k) account.

401(k) Loan Borrowing Limits

The IRS caps 401(k) loans at the lesser of:

There's one exception: if 50% of your vested balance is less than $10,000, you can still borrow up to $10,000 (as long as the total doesn't exceed your vested balance).

For example, if your vested 401(k) balance is $80,000, you could borrow up to $40,000 (50%). If your vested balance is $120,000, you'd be capped at $50,000 (the IRS maximum). And if your vested balance is only $15,000, you could borrow up to $10,000 under the small-balance exception.

Keep in mind that "vested balance" matters here. If your employer contributes to your 401(k) with a vesting schedule, you may not have access to those funds yet. Only the portion you've fully vested in counts toward your borrowing limit.

401(k) Loan Requirements

The requirements for a 401(k) loan are relatively straightforward compared to traditional bank loans:

Most plans don't require you to explain why you need the money. However, some plans restrict loans to specific purposes like preventing eviction, medical expenses, or education costs.

401(k) Loan Interest Rates

The interest rate on a 401(k) loan is typically set at the prime rate plus 1% to 2%. Your plan documents specify the exact formula.

As of early 2026, the U.S. prime rate sits around 7.5%, which means most 401(k) loan rates fall in the 8.5% to 9.5% range. That's generally lower than what you'd pay on a credit card or an unsecured personal loan, especially if you have fair or poor credit.

The key difference from other loans: the interest you pay doesn't go to a bank or lender. It goes back into your 401(k) account. You're essentially paying interest to yourself. This makes 401(k) loans feel less expensive, though there's a hidden cost: the money you borrowed stops earning investment returns while it's out of your account.

401(k) Loan Repayment Rules

The IRS requires that 401(k) loans be repaid within five years, with payments made at least quarterly. Most employers set up automatic payroll deductions so you don't miss payments.

There is one exception: if you use the loan to purchase your primary residence, many plans allow a longer repayment period (often 10 to 15 years, but up to 25 years in some cases).

What counts as repayment? Each payment includes both principal and interest. The full amount goes back into your 401(k), restoring your retirement savings over time.

Can you pay off early? Most plans allow early repayment without any prepayment penalties. Paying off the loan faster means getting your money back into the market sooner.

What if you miss a payment? If payments aren't made on schedule, the outstanding balance may be treated as a distribution. That triggers income taxes on the full amount, plus a 10% early withdrawal penalty if you're under age 59 and a half.

Benefits of 401(k) Loans

401(k) loans have several advantages over traditional borrowing options:

Drawbacks of 401(k) Loans

Despite the appeal, 401(k) loans carry significant risks that can hurt your long-term financial health:

What Happens If You Leave Your Job With a 401(k) Loan?

This is one of the biggest risks of borrowing from your 401(k). If you leave your employer for any reason, whether you quit, get laid off, or retire, your plan may require you to repay the outstanding loan balance within 60 to 90 days.

If you can't repay it in time, the remaining balance is treated as a distribution. That means:

For example, if you have $20,000 remaining on your 401(k) loan when you leave your job and can't repay it, you might owe $5,000 to $7,000 in combined taxes and penalties (depending on your tax bracket).

Some plans do allow you to continue making loan payments even after you leave, but this is not common. It's worth checking your plan's specific rules before borrowing, especially if you think a job change could be on the horizon.

401(k) Loan vs. Hardship Withdrawal

If you need cash from your retirement account, you generally have two options: a loan or a hardship withdrawal. They work very differently.

A 401(k) loan is temporary. You borrow the money and pay it back with interest, and your retirement balance is eventually restored. No taxes or penalties apply as long as you repay on time.

A hardship withdrawal is permanent. The money leaves your account for good. You'll owe income taxes on the full amount, and if you're under 59 and a half, you'll pay the 10% early withdrawal penalty as well. You also can't repay or roll over a hardship withdrawal.

The IRS requires that hardship withdrawals meet specific criteria, such as unreimbursed medical expenses, costs to prevent eviction, funeral expenses, or certain repair expenses for your primary residence.

In most cases, a 401(k) loan is the better option if your plan offers one. You keep your retirement savings intact (eventually), avoid taxes and penalties, and pay a lower total cost.

Alternatives to 401(k) Loans

Before tapping your retirement savings, consider these alternatives:

Personal loan. If you have good credit, a personal loan can offer competitive rates without touching your retirement funds. You'll typically get $1,000 to $50,000 with repayment terms of 2 to 7 years.

Home equity loan or HELOC. Homeowners can borrow against their equity at rates that are often lower than personal loans. The interest may be tax-deductible if used for home improvements.

0% APR credit card. For shorter-term needs, a 0% intro APR credit card can give you 12 to 21 months of interest-free borrowing. Just make sure you can pay off the balance before the promotional period ends.

Emergency fund. If you haven't built one yet, this is a strong reminder to start. Financial experts recommend keeping 3 to 6 months of living expenses in a readily accessible savings account.

Side income. Depending on the amount you need and the timeline, earning extra money through freelancing, selling unused items, or picking up temporary work may be a better path than borrowing from your future self.

Is It Smart to Borrow Against Your 401(k)?

It depends on your situation. A 401(k) loan can make sense when:

A 401(k) loan is probably a bad idea when:

The bottom line: a 401(k) loan should be a last resort, not a first option. The long-term cost of pulling money from your retirement account is almost always higher than it appears on the surface.
