How does a 401(k) loan work?

Workers contribute to 401(k) plans as a way to save for retirement automatically through payroll deductions. With regular contributions, these retirement accounts tend to grow into one of the largest assets you own. But many workers are unaware that you can actually borrow money from your retirement account.

So, how does a 401 (k) loan work? Learn about eligibility rules, maximum loan amounts, repayment terms, and other important details you need to know before borrowing.

How does a 401(k) loan work?

A 401(k) loan lets you borrow money from your own retirement savings and pay it back over time—essentially making you both the lender and the borrower. Adding to its appeal, approval typically doesn’t depend on credit scores or debt-to-income ratios like traditional loans. While it can feel like an easy way to access cash, it’s important to weigh both the short- and long-term impact before tapping into your nest egg.

The key features of a 401(k) loan are:

• Loan amount. The maximum you can borrow from a traditional lender is determined by your existing debt and ability to repay the loan. A 401(k) loan maximum is set by law at 50% of your vested account balance or $50,000, whichever is less.
• Repayment period. Loans taken against your 401(k) must be repaid within five years, unless you're using the funds for a home purchase.
• Interest rates. Traditional lenders set interest rates using current market conditions, your credit history, the loan amount, repayment term, and other factors. Interest rates on 401(k) loans are set by the plan. A common interest rate is Prime + 1%. Any loan interest is returned directly to your account.
• Payments. Payment amounts are usually based on the loan amount, interest rate, and loan term. Traditional lenders typically require monthly payments, while 401(k) loans are often repaid through regular paycheck deductions. However, the IRS only requires that you pay a 401(k) loan at least once a quarter.
• Can have multiple loans. You can get approved for multiple 401(k) loans. However, the maximum combined loan amount is the lesser of $50,000 or 50% of your account balance. The exception is if you apply for a second loan within one year of your original loan request. Then, the maximum combined loan amount is based on the original loan amount of the first loan, not its current balance, even if you've paid down the balance significantly or paid it off.
• The loan can be refinanced. Borrowers may refinance their 401(k) loan and replace it with a new one to take advantage of lower interest rates.

401(k) loan pros and cons

401(k) vs. alternatives

A 401(k) loan offers many advantages, but with major downsides. It's wise to explore all options before risking a serious retirement savings gap.

401(k) hardship withdrawal

A 401(k) hardship withdrawal allows you to take money from your retirement account that isn’t paid back. To qualify, you must be facing an immediate and heavy financial need—like medical expenses, tuition, funeral costs, home repairs, or avoiding eviction or foreclosure.

• Withdrawals before age 59½ usually incur a 10% penalty
• Hardship withdrawals waive the 10% penalty
• You still owe income taxes on the amount withdrawn
• Important to factor in taxes when deciding how much to take

Personal loan

A personal loan provides a lump sum of cash with a fixed interest rate that you repay over time. Approval is based on your credit history and ability to repay, rather than collateral.

• Approval based on creditworthiness and income
• Lower credit scores may result in higher interest rates
• Often offers longer repayment terms than a 401(k) loan
• Missed payments impact credit score

Home equity investment

A home equity investment (HEI) gives homeowners a lump sum of cash upfront in exchange for a portion of their home's future appreciation. There are no monthly payments. An HEI does not require proof of income, and you can get approved even if you have less-than-perfect credit.

• No monthly payments
• Won't impact your mortgage rate
• Repayment happens when you sell, refinance, or end the term
• Flexible 30-year term; no prepayment penalty

Home equity line of credit (HELOC)

A more traditional way to tap your home's equity is to take out a home equity line of credit (HELOC). A HELOC is a revolving line of credit based on your home equity. You can borrow as needed and make interest-only payments during the draw period.

• Good to excellent credit and stable income are needed to qualify
• Variable interest rate means payments can change over time
• Draw period typically lasts 10 years
• Converts to a repayment period with fixed payments afterward

Home equity loan

A home equity loan provides a lump sum that you repay over time with a fixed interest rate and set monthly payments.

• Usually requires good to excellent credit and sufficient income
• Loan terms typically range from 5 to 20 years
• Interest rate is more competitive than credit cards and personal loans

The bottom line

A 401(k) loan can be a convenient way to access cash when you need it, with simple approval and repayments going back into your own account. While it’s important to consider the impact on your long-term retirement growth, it can be a useful tool for short-term financial needs. Always review your retirement plan rules and repayment terms before borrowing.
