How to use this calculator
- Home. Your home's value, what you owe, the rate and the years left.
- Cash. The cash you need and the years until you repay it or sell. Your vested 401(k) balance sets the 401(k) loan limit. Home prices (+5% a year, the long-term US average the CFPB cites from FHFA) and the multiple (2x, the CFPB's example) drive the home equity investment.
- Rates. Examples to replace with real quotes: HELOC 8%, the prime rate (7% on October 2, 2026) plus 1 point; home equity loan 8% (U.S. Bank's lowest listed 10-year rate: 7.65%); refinance 7.28%, Freddie Mac's 30-year average for the week of October 1, 2026; personal loan 11.86%, the Federal Reserve's bank average. Your plan sets the 401(k) loan rate; 401(k) growth is what the money would have earned in the plan.
- Results. The lowest yearly cost, or a close call within a quarter point, and each monthly payment. The breakdown explains every number.
How the options are compared
Cost in dollars = payments + what you still owe at the end − the cash
Yearly cost = the rate at which the cash equals those payments, like an APR over your years
Example ($50,000 for 10 years, 3% mortgage): HELOC $40,000 at 8.0%, 401(k) loan $10,829 at 8.0%, cash-out refinance $157,121 at 24.5%
Options are ranked by yearly cost because dollars favor whatever is repaid fastest: the 401(k) loan costs fewer dollars only because it must be paid off in 5 years. A refinance's cost includes the higher rate on your old balance; a 401(k) loan's is the growth the money misses.
The terms of each option are fixed (see the breakdown). To change them, use the HELOC calculator, the home equity loan calculator or the cash-out refinance vs. HELOC calculator.
The options at a glance
| Option | How you get the money | Payments | Limit used here | Main risk |
|---|---|---|---|---|
| HELOC | A credit line you draw as needed | Can be interest-only at first | 85% of value minus what you owe (Bank of America, PenFed) | Variable rate; the line can be frozen |
| Home equity loan | One lump sum | Equal payments | Same as the HELOC | Need more later: apply for a new loan |
| Cash-out refinance | A bigger mortgage replaces yours | One mortgage payment | 80% of value, one-unit main home (Fannie Mae) | The new rate applies to everything you owe |
| Home equity investment | Cash for a share of your home's future value | None, then one lump sum at sale or term end | Set by each company; here, the stake must fit within your equity | Hard-to-predict settlement; you may have to sell |
| 401(k) loan | A loan from your retirement plan | At least quarterly, repaid within 5 years | Lesser of 50% of vested balance or $50,000 (IRS) | Leaving your job can make the balance due |
| Personal loan | A lump sum, not secured by your home | Fixed monthly payments | Wells Fargo: up to $100,000 | A higher rate than home-secured loans |
Your home secures the first three, and a home equity investment company takes a lien on it too. If you fall behind on a home-secured loan, you could lose your home.
When a cash-out refinance comes out ahead
A cash-out refinance moves your whole mortgage to the new rate. In the example, $250,000 goes from 3% to 7.28% to raise $50,000, so the cash costs about 24.5% a year. With everything else the same, the refinance costs less per year than the HELOC once your current rate is above about 7.67%; at 8%, the cash costs about 6.6% a year.
HELOC vs. 401(k) loan
At the example rates both cost about 8.0% a year, but the payments differ. The $50,000 HELOC costs $333 a month in interest for 10 years, then $418, at a rate that can change. The 401(k) loan takes $1,014 a month, because the IRS requires repayment within five years. Its real cost is the growth the money misses in your plan.
The HELOC is secured by your home. The 401(k) loan is not, but your plan may require full repayment if you leave your job. If you cannot repay, the balance is taxed as income, and you may owe an additional 10% tax if you are under 59½; rolling it over to an IRA by your tax filing deadline avoids the immediate tax.
Home equity investment vs. HELOC
A home equity investment pays cash now with no monthly payments; in return you owe one lump sum later, based on your home's value. In the CFPB's illustration, a homeowner gets $50,000 on a $500,000 home for a 20% stake, with a 20%-a-year cap. Settling after 3 years costs $86,400; after 10 years of 6% growth, $179,085; with no growth at all, $100,000. A $50,000 HELOC at 9%, interest only, costs $375 a month, $45,000 of interest over 10 years, and you still owe the $50,000. Counting total dollars, the CFPB found the contract would cost less only if the home lost at least 5% of its value over those 10 years. The yearly cost here also credits paying later, so with flat prices over many years a contract can rank lower than a loan.
Where it can help is approval: the CFPB notes HELOCs often have stricter underwriting, and these contracts are marketed as available to homeowners with no income and low credit scores.
Costs and risks to check
- Up-front costs. Refinancing costs 3% to 6% of the loan, according to Freddie Mac. Home equity investment processing fees are often 3% to 5%, plus third-party fees. Several large lenders advertise no closing costs on home equity loans.
- A cost that moves. HELOC rates are usually variable. A home equity investment's settlement moves with your home's value up to any cap, and some contracts have no cap.
- Your plan's rules. Employers do not have to offer 401(k) loans, and some plans need your spouse's written consent for a loan over $5,000.
Questions about tapping home equity
What is the cheapest way to take equity out of your home?
It depends on your mortgage rate and how long you need the money. With our example rates and $50,000 for 10 years, a HELOC and a home equity loan each cost about 8.0% a year, a home equity investment about 12.7% if home prices rise 5% a year, and a cash-out refinance of a 3% mortgage about 24.5%, because the whole balance moves to 7.28%. The refinance only costs less per year than the HELOC once your current rate is above about 7.67%.
Is tapping into your home equity a good idea?
It can cost less than unsecured credit: the Federal Reserve's average rate on 24-month personal loans at banks was 11.86% in the second quarter of 2026, against 8% for our HELOC example. But your home secures the debt: if you fall behind, you could lose it. Interest is tax-deductible only if you use the money to buy, build or substantially improve the home, according to the IRS. Payments differ too: in our example, from $0 extra a month with a home equity investment to $931 with a cash-out refinance.
What is the monthly payment on a $50,000 home equity loan?
At a fixed 8%, about $1,014 a month over 5 years, $607 over 10 years, $478 over 15 years and $418 over 20 years. That is principal and interest only. As a HELOC at 8%, the same $50,000 would cost $333 a month while you pay interest only.
What is the monthly payment on a $50,000 401(k) loan?
$50,000 is the most the IRS allows, and only if your vested balance is at least $100,000. The loan must be repaid within 5 years in payments at least every quarter, so at 8% it takes about $1,014 a month. Your plan sets the rate, which federal rules require to be in line with what lenders charge, and the interest goes back into your own account.
What are the downsides of a 401(k) loan?
The money stops growing in the market while it is out. If your plan would earn 10% a year, the growth missed on a $50,000 loan comes to about $13,536 over 5 years, more than the $10,829 of interest you pay back in at 8%. Your plan may require full repayment if you leave your job; if you cannot, the balance is taxed as income and you may owe an additional 10% tax if you are under 59½.
What is the downside of a home equity investment?
The CFPB found that under many contracts the settlement grows 19.5% to 22% a year in the early years, more than most home-secured credit, and that the total paid is often higher than with a mortgage-secured loan. You repay it all at once, at the end of a 10- to 30-year term or when you sell, generally with no partial payments. If you cannot pay, you may have to sell or face foreclosure. In our example it costs about 12.7% a year against 8.0% for a HELOC.
What is the cheapest way to borrow $100,000?
On our example home ($450,000, $250,000 owed) with the example rates, for $100,000 over 10 years the HELOC and home equity loan tie at about 8.0% a year. A 401(k) loan cannot go above $50,000, a cash-out refinance tops out near $99,200 under Fannie Mae's 80% limit, and a 5-year personal loan at 11.86% would cost $2,217 a month.
