HELOC vs 401(k) loan: What's the safer option in 2026?

When you need access to a significant amount of money, two options that often come up for homeowners are a home equity line of credit (HELOC) and a 401(k) loan. Both are ways to borrow against assets you've already built: your home equity or your retirement savings. Each comes with benefits and drawbacks. 

HELOC vs 401(k) loan: a quick comparison of the risks that matter

Before diving into the details, here's how these two options compare:

How a HELOC works (and what to know about the risks)

A HELOC is a second mortgage against the equity in your home. Most HELOCs have variable interest rates, which means your payment could change over time. Some lenders offer fixed-rate options. Before signing, ask your lender how the rate is structured and how payments could change.

A typical HELOC has two phases: a draw period, during which you access funds, and a repayment period, during which you pay back what you borrowed. Costs may include an appraisal, closing costs, and annual fees, all of which vary by lender.

HELOC risks

If you miss payments, your home could be at risk. A HELOC also affects your debt-to-income ratio (DTI), which matters if you plan to apply for other credit. Your DTI is the percentage of your income that is spoken for by your debts and housing expenses. If your required monthly payments are too high, relative to your income, it could be harder to get approved for a new loan.

Questions to ask your lender

• How is my rate calculated?

• When and how could my payment change?

• What fees apply?

• What are the draw rules?

How a 401(k) loan works (and the rules risk worth knowing)

A 401(k) loan is a loan from your own retirement account, with no credit check required. Repayment terms depend on your specific employer's plan, though federal law sets limits on how much you may be able to borrow.

Generally, you may borrow up to 50% of your vested account balance or $50,000, whichever is less. If 50% of your vested balance is under $10,000, you may be able to borrow up to $10,000. Repayments are often deducted directly from your paycheck.

If you leave your job for any reason, your plan may require you to repay the outstanding balance quickly. If you are unable to repay, the remaining amount could be treated as a taxable distribution. If you are under age 59½, you may also face a 10% early withdrawal tax.

401(k) loan risks

Lost compounding. Money borrowed from your 401(k) is not in the market.  No earnings happen. You can repay what you borrowed, but you can’t get lost growth back.

Double-taxation. The money in your 401(k) was pre-tax. When you pay it back, you’re using after-tax dollars. Then you’ll pay income taxes on that money when you withdraw it in retirement. A 401(k) loan creates double-taxation on the repaid amount.

Reduced contributions. Many people don’t make their normal contributions while they’re paying their loan back. Those loan payments are going into the account, so it might feel like a contribution. But it’s not. It’s just getting you back to where you were. If you don’t make new contributions, you could lose out on your employer match.

Opportunity cost if you leave your job. If you separate from your employer for any reason, the full balance could become due. If you can’t afford to pay it back, you could pay taxes and penalties on the amount you borrowed. 

Questions to ask your plan administrator

• What is the maximum I can borrow?

• What are the repayment terms?

• What happens if I leave my employer before the loan is repaid?

Which could be less risky: a checklist to help you decide

Use these questions to help think through which option may fit your situation better:

1. How long do you need the money? HELOCs often work well for longer timelines; 401(k) loans are typically better suited for shorter-term needs.

2. How stable is your income and employment? If you separate from your job before the loan is repaid, the balance could become a taxable distribution.

3. Can your budget absorb payment changes? If you have a variable-rate HELOC, your payment amount could change if rates change.

4. How much do you have in each asset? The size of your home equity and your vested 401(k) balance may determine which option is even available to you.

When a HELOC could be the less risky fit

A home equity line of credit may work better for you if you want to preserve your retirement savings, have sufficient equity and a clear repayment plan, and can manage a potentially variable payment over time—or are able to get a fixed-rate line of credit.

When a 401(k) loan could be the less risky fit

A 401(k) loan may be a better fit if you:

• Need the money for a short period

• Are confident you can repay within your plan's rules

• Do not have sufficient home equity or prefer not to go through the HELOC application process

• Prefer not to put your home up as collateral

• Are willing to accept the retirement trade-offs

Alternatives to consider before you borrow

It may be worth exploring other options before tapping into home equity or retirement savings. A personal loan for debt consolidation could make sense if it reduces your overall borrowing cost compared with what you are currently paying. Temporary adjustments to your budget or using existing savings for part of the expense are also worth considering.

If you have heard of a 401(k) hardship distribution, note that it is different from a loan and may carry its own tax consequences.
