Cash-out refinance vs. HELOC in 2026: which costs less?
With 30-year rates near 7.3% and the prime rate at 7.00%, a HELOC usually costs less than a cash-out refinance if your mortgage rate is low. Worked comparison and rules.
The short answer
In 2026, a HELOC usually costs less than a cash-out refinance if your current mortgage rate is well below today's average, because a cash-out refinance reprices your whole balance. With the 30-year average at 7.32% (Freddie Mac, October 22, 2026) and the prime rate at 7.00% (Federal Reserve, Oct. 20, 2026), taking $60,000 out of a home with a $300,000 balance at 3.5% raises the monthly payment far less through a HELOC than through a cash-out refinance.
Key numbers
- 30-year average
- 7.32% (Freddie Mac)
- Prime rate
- 7.00% (Oct. 20, 2026)
- Cash-out max LTV
- 80% (conventional 1-unit and FHA)
- HELOC rate basis
- Prime + margin, usually variable
Side-by-side comparison
| Cash-out refinance | HELOC | |
|---|---|---|
| What happens to your first mortgage | Replaced by a new, larger loan at today's rate | Stays in place at its current rate |
| Rate | Fixed or adjustable first-mortgage rate | Usually variable: prime rate plus a margin |
| Maximum borrowing | 80% of value on a 1-unit primary home (Fannie Mae, FHA) | Often 80% to 90% combined loan-to-value, set by the lender |
| Closing costs | Typically 2% to 5% of the whole new loan | Often low; some charge annual fees |
| Payments | One fixed payment | Interest-only possible during the draw period, then principal and interest |
| Best when | Your current rate is at or above today's rates, or you need a large fixed-rate sum | Your current rate is low and you want to keep it |
Worked example at this week's rates
You owe $300,000 at 3.50% with 25 years left (principal and interest about $1,502 a month) on a $500,000 home and want $60,000.
- Cash-out refinance: new loan of $360,000 plus about $10,800 in closing costs (3%), so about $370,800 at 7.32% for 30 years. Payment: about $2,547 a month, roughly $1,045 more than today.
- HELOC: keep the $300,000 first mortgage and draw $60,000. At an illustrative 8.50% (prime of 7.00% plus a 1.50% margin), interest-only payments are about $425 a month during the draw period, or about $521 a month if repaid over 20 years at that rate.
The HELOC adds roughly $425 to $521 a month; the cash-out refinance adds about $1,045. The HELOC rate can rise if the Fed raises rates again, so stress-test the payment at a rate 2 points higher. HELOC margins vary by lender and credit score; the 1.50% margin here is an illustration, not a quote.
When a cash-out refinance wins
- Your current mortgage rate is close to or above today's average.
- You want one fixed payment and no rate risk on the borrowed amount.
- You're also consolidating high-rate debt and can lower your overall monthly payments. Run the numbers in the cash-out refinance calculator.
Rules that apply to both
- Interest deductibility: interest on home equity debt is deductible only if the money buys, builds or substantially improves the home securing the loan (IRS Publication 936).
- Waiting periods: a conventional cash-out refinance needs the existing first mortgage to be at least 12 months old (Fannie Mae B2-1.3-03); FHA needs 12 months of living in the home.
- Your home is the collateral. Missing payments on either can lead to foreclosure.
Frequently asked questions
Is a HELOC or cash-out refinance better in 2026?
If your current rate is well below today's roughly 7% average, a HELOC usually costs less because your low-rate first mortgage stays. If your rate is already near today's level, a cash-out refinance gives one fixed payment.
Are HELOC rates higher than mortgage rates?
Usually yes. HELOCs are typically priced at the prime rate (7.00% on Oct. 20, 2026) plus a margin, and they are variable.
How much can I borrow with a cash-out refinance vs. a HELOC?
A conventional or FHA cash-out refinance is capped at 80% of your home's value on a 1-unit primary home. HELOC limits are set by each lender, often 80% to 90% combined loan-to-value.
Do HELOC rates go up when the Fed raises rates?
Yes, for variable-rate HELOCs. Banks move the prime rate with the federal funds rate, so a quarter-point Fed hike usually raises HELOC rates a quarter point.
Which has lower closing costs?
HELOCs, usually. A cash-out refinance charges 2% to 5% of the entire new loan amount.
