HELOC vs Cash-Out Refinance: Which Is Cheaper?

Most guides stop at “a HELOC is a second loan, a cash-out refinance replaces your first one” and leave you to work out the cost yourself. That framing hides the number that actually decides it.

The HELOC vs cash out refinance choice is not about product structure. It is about the rate on the mortgage you already have. A cash-out refinance re-prices your entire balance at today’s rate. A HELOC leaves that balance alone and prices only the new money. That is the whole decision, and it has a break-even point you can calculate. DollarVisor takes no payment for placement: companies cannot pay for position in our rankings.

Here is a quick overview of the two products before we run the numbers.

1. Which One Should You Take?

Quick Answer: Our pick is the HELOC for any homeowner whose current mortgage rate is below roughly 7%. It leaves your cheap first mortgage untouched and charges the higher rate only on the money you actually draw. Take the cash-out refinance only if today’s rate would also lower your existing payment. Start with how refinancing works if that part is fuzzy.

Both products turn home equity into cash and both put your house up as collateral. The difference is what happens to the debt you already carry.

• Take the HELOC if your existing mortgage rate is below about 7%, which covers the large majority of American homeowners today.
• Take the cash-out refinance if your existing rate is above today’s market rate, or if you need a fixed payment you can plan around for 30 years.
• Take neither yet if the cash is for something that will not still exist in five years. Section 9 covers that case.

Companies cannot pay for placement in our rankings. Every figure below comes from federal data or arithmetic you can rebuild in a spreadsheet.

2. What Actually Changes in Each Deal?

Quick Answer: A cash-out refinance pays off your old mortgage and writes a new, larger one at today’s rate, so every dollar you owe gets re-priced. A HELOC sits behind your mortgage as a second lien with its own floating rate, so only the new money is re-priced. See our guide to home loans for the underlying mechanics.

That structural difference drives everything else: the rate, the fees, and how fast your payment can change.

• The rate you pay. Refinance rates are fixed for the life of the loan. HELOC rates float with the bank prime rate, which stood at 6.75% on August 11, 2026, per the Federal Reserve’s H.15 release, plus a lender margin of roughly half a point to two points.
• What you pay it on. A refinance charges interest on the full new balance from day one. A HELOC charges interest only on what you have drawn.
• The fees. A refinance carries full mortgage closing costs, commonly 2% to 5% of the loan. Most HELOCs cost a few hundred dollars or nothing.
• The timeline. A HELOC has a draw period, usually 10 years, when payments can be interest-only. After that it converts to a repayment schedule and the payment jumps.

That last point is the HELOC’s real cost, and it arrives a decade after you sign.

3. What Does Each Option Cost Right Now?

Quick Answer: On a $500,000 home with $250,000 owed at 4.25%, pulling $75,000 costs $114,046 over five years by refinance and $79,536 by HELOC. The HELOC saves $34,510 and lowers the monthly bill by $295. It also leaves you owing $17,332 less at year five, because a fresh 30-year clock restarts your amortization.

The refinance takes the market rate of 6.67% from Freddie Mac’s Primary Mortgage Market Survey on August 13, 2026. The HELOC takes prime plus one point, or 7.75%, with interest-only payments during the draw period.

The refinance loses every row, and the reason is in the second one. Refinancing drags $250,000 of 4.25% money up to 6.67%. The HELOC re-prices $75,000 only.

4. At What Mortgage Rate Does Refinancing Win?

Quick Answer: At 7.04%. Below that, keeping your mortgage and adding a HELOC costs less over five years. Above it, the refinance pulls ahead because it is now cutting your rate as well as raising cash. Federal data shows 77.9% of outstanding American mortgages sit at 6% or below, so the HELOC route wins for most homeowners.

This break-even is the number almost nobody publishes, and it is the only one that changes the answer. Draw periods and fixed-versus-floating are tiebreakers.

The break-even sits 0.37 points above the current refinance rate, not at it. That gap is the closing costs and the restarted 30-year clock working against you. Only 22.1% of outstanding mortgages carry a rate above 6%, per the FHFA’s National Mortgage Database, and only a slice of those clear 7.04%.

5. What If the Prime Rate Moves?

Quick Answer: A HELOC payment moves the month prime moves. On $75,000, every one-point rise adds $63 a month and $3,750 to five-year interest. Even a two-point jump still leaves the HELOC route cheaper than a fixed-rate refinance. The floating rate is a real risk, just a smaller one than it looks.

This is the strongest argument for refinancing in the heloc vs cash out refinance debate, and it deserves a number rather than a warning. Prime has been 6.75% since December 2025.

Compare the worst row to the refinance. Even at 9.75%, the HELOC route costs $1,964 a month against the refinance’s $2,133, and the five-year gap still favors the HELOC by $27,010.

6. Does It Matter How You Draw the Money?

Quick Answer: Enormously, and this is where the HELOC’s second advantage lives. Taking $75,000 in three $25,000 stages costs $17,438 in five-year interest instead of $29,062 all at once: an $11,624 saving for the same total cash. A refinance cannot do this. It hands you the full sum and starts amortizing it on day one.

Staged borrowing fits how equity money is actually spent: a kitchen this year, a roof in year three, tuition in year five.

Read the middle row honestly. Draw everything at once and the refinance is slightly cheaper on that slice. The HELOC still wins overall only because it protects your first mortgage.

7. How Do You Compare Two Real Quotes?

Quick Answer: Ignore both headline rates and compare total five-year cost instead. Four steps get you there: find your current rate, ask each lender for the full fee sheet, price the HELOC as prime plus its margin, then add up payments and fees for five years. Our mortgage calculator handles the arithmetic.

A refinance quote leads with the fixed rate. A HELOC quote leads with a discounted introductory rate that expires. Neither number is the cost.

1. Find your current rate and remaining term. Both sit on your monthly statement, and without them the break-even in Section 4 is unusable.
2. Get the full fee sheet in writing. On a refinance that is the Loan Estimate, due within three business days. On a HELOC, ask about annual, inactivity and early-closure fees.
3. Price the HELOC as prime plus margin, not as the teaser rate. Ask what the rate becomes when the promotion ends, and what the lifetime cap is.
4. Add up five years of payments plus fees for each route. The lower total is the cheaper product, whatever the headline rates say.

Step two catches the most money. Refinance closing costs are usually rolled into the loan, so you never write a check and never feel them: you just pay interest on them for 30 years.

8. How Much Equity Can You Actually Tap?

Quick Answer: Most lenders cap your combined borrowing at 80% to 85% of the home’s value. On a $500,000 home with $250,000 owed, an 80% cap leaves $150,000 available. Both products use the same limit, so it rarely decides between them, but it does decide whether either is possible. Check the loans hub for program-specific caps.

Equity is not scarce right now. Mortgage holders are sitting on a record amount of it, with roughly $11.7 trillion classed as tappable and an average near $212,000 per borrower, per ICE’s Mortgage Monitor.

Homeowners are using it, too. HELOC balances rose $13 billion in the second quarter of 2026 to $459 billion, $48 billion higher than a year earlier, according to the New York Fed’s household debt report. Lenders extended $19 billion more in HELOC limits in the same quarter, and borrowers moved into serious delinquency at just 1.15%, against 6.97% for credit cards.

9. When Is Neither the Right Answer?

Quick Answer: Skip both when the money is for something that will not outlast the debt, when your income is unstable, when you plan to sell within three years, or when you are borrowing to cover a shortfall rather than to fund a plan. Each of these converts a temporary problem into a permanent lien on the home you financed.

Everything on this page is secured by your home. That is why the rates are low, and it is also the risk.

• Short-lived spending. A vacation financed over 30 years costs several times its sticker price and leaves nothing behind.
• Unstable income. Missing a HELOC payment is a step toward foreclosure, not a late fee.
• A move within three years. Refinance closing costs never get earned back, and a HELOC has to be cleared at sale.
• Covering a monthly gap. If the budget does not balance, borrowing against the house delays the reckoning and raises the stakes.
• An unclear repayment plan. Our base-case $484 interest-only bill becomes $616 once the draw period ends.

If you land in one of these groups, wait. Equity is not going anywhere, and the math will still be there when your situation is steadier.

10. The Short Version

Quick Answer: Check your current mortgage rate first. Below 7.04%, take the HELOC and keep the cheap money you already have. Above it, the cash-out refinance raises cash and cuts your rate at the same time. More head-to-heads live in our loans coverage.

This question feels hard because it is usually asked backwards. People compare a 7.75% HELOC against a 6.67% refinance, pick the smaller number, and never notice they just re-priced $250,000 of 4.25% debt to do it.

So run one calculation before any lender call: your existing rate against 7.04%. That settles the heloc vs cash out refinance question in most households, and the same show-the-math habit works everywhere else, from mortgages to choosing between two travel rewards cards.

11. Frequently Asked Questions

1. Is a HELOC cheaper than a cash-out refinance?

Usually, yes. In our base case the HELOC costs $79,536 over five years against $114,046 for the refinance, a $34,510 saving. It wins because it leaves your existing mortgage rate alone. The refinance only becomes cheaper once your current rate passes about 7.04%.

2. Why is a HELOC cheaper when its rate is higher?

Because the rate applies to far less money. A HELOC charges 7.75% on the $75,000 you draw. A cash-out refinance charges 6.67% on the whole $331,633, including $250,000 you were already paying 4.25% on. The blended cost is 5.06% with the HELOC and 6.67% with the refinance.

3. What are the closing costs on a cash-out refinance?

Typically 2% to 5% of the new loan, or $6,633 on the $331,633 loan in our example. Most lenders roll it into the balance, so you pay interest on those fees for the full term. HELOC costs are far lower, often a few hundred dollars or nothing.

4. What happens to my HELOC payment when rates rise?

It changes within a billing cycle or two, because the rate is prime plus a fixed margin. On a $75,000 draw, every one-point rise in prime adds about $63 a month. Prime was 6.75% in August 2026. Ask for the lifetime rate cap before signing.

5. Can I get a HELOC and a cash-out refinance at the same time?

Yes, if your combined loan-to-value stays inside the lender’s cap, usually 80% to 85%. In practice it rarely helps: you pay full refinance closing costs and give up your old rate, then still carry a floating second lien on top.
