HELOC vs Cash-Out Refinance: The 30-Second Answer

If your current mortgage rate is below 5.5%, choose a HELOC. If your current rate is at or above today's refinance rate (5.5–6.5% in May 2026), a cash-out refinance is almost always cheaper. The break-even point is simple math: a cash-out refinance forces you to refinance your entire mortgage balance at today's rate, so you only win if today's rate beats your existing rate. A HELOC leaves your first mortgage alone and charges interest only on the second-lien balance.

For a homeowner with a $400,000 mortgage at 3.25% who needs $75,000, a cash-out refinance at 6.25% costs roughly $148,000 in extra lifetime interest compared to a HELOC at 8.5% paid off over 10 years. The math is brutal and counterintuitive — the "lower" 6.25% rate is more expensive because it resets your entire $475,000 balance, not just the $75,000 you actually need.

The Two Products in Plain English

A HELOC (Home Equity Line of Credit) is a second mortgage that works like a credit card secured by your house. You're approved for a credit limit — say $100,000 — and you draw against it as needed. You pay interest only on what you've drawn. Most HELOCs have a 10-year draw period followed by a 20-year repayment period, and rates are variable, tied to the Prime Rate (currently 7.5% in May 2026). Typical HELOC rates are Prime + 0.5% to Prime + 2%, so 8.0%–9.5% today.

A cash-out refinance replaces your existing mortgage with a new, larger one. If you owe $300,000 on a $600,000 home and want $75,000 cash, you'd take out a new $375,000 mortgage at today's rate (6.0%–6.5% for a 30-year fixed in May 2026). You get the $75,000 difference at closing, minus 2%–5% in closing costs.

The Real Cost Comparison: A Worked Example

Let's compare both options for a homeowner who needs $75,000 to renovate a kitchen and finish a basement. Their current situation: $400,000 remaining balance on a 30-year mortgage at 3.25%, originated in 2021, with 25 years left. Home value: $720,000. Available equity (at 85% combined loan-to-value): $212,000.

Option A: Cash-Out Refinance at 6.25%

Option B: Keep the 3.25% Mortgage, Add an $75K HELOC at 8.5%

Even though the HELOC carries a higher headline rate (8.5% vs 6.25%), it costs dramatically less because you're only paying that rate on $75,000 — not on $400,000 of mortgage you already locked in at 3.25%.

When Cash-Out Refinance Actually Wins

Cash-out refinances are the better choice in three specific situations:

1. Your existing rate is higher than today's rate. If you have a 7.5% mortgage from 2023 and today's rate is 6.0%, refinancing your whole balance at 6.0% saves money on the existing debt while also funding the cash-out. Run the numbers — the savings from the rate reduction can completely offset the cost of the larger balance.

2. You need a large amount relative to your existing balance. If you owe $50,000 but need $200,000 cash, you're borrowing 4x your existing balance. The rate reset penalty becomes less painful because most of the new loan is the new money anyway.

3. You want a fixed rate for predictability. HELOCs have variable rates. If the Fed hikes again, your HELOC payment goes up. A cash-out refinance locks in today's rate for 30 years. Risk-averse borrowers may pay the premium for certainty — use our refinance breakeven calculator to quantify the tradeoff.

When HELOCs Win (Most of 2026)

HELOCs beat cash-out refinances in these situations, which describe most American homeowners right now:

1. You have a pandemic-era ultra-low mortgage. The roughly 60% of US mortgages with rates below 4% would be insane to refinance into a 6%+ environment. Keep that golden rate untouched.

2. You need flexibility on draw timing. Renovating in phases? Paying college tuition over four years? A HELOC lets you draw as needed and only pay interest on the outstanding balance. Cash-out gives you all the money on day one — and you start paying interest on the full amount immediately.

3. You plan to pay it back fast. Borrowing $40,000 to bridge a six-month liquidity gap? The HELOC's interest-only draw period and ability to repay early without resetting your first mortgage make it ideal. Cash-out refinance closing costs alone (2–5% of the loan) often exceed the total interest on a short-term HELOC.

4. You want to preserve your tax deduction. HELOC interest is tax-deductible only when used for home improvements (IRS Publication 936). Cash-out refinance interest follows the same rule. But because a HELOC's balance is cleanly separated from your first mortgage, it's easier to track and document for tax purposes.

The Closing Cost Wedge

This is the factor most online comparisons skip. A cash-out refinance has typical closing costs of $8,000–$18,000 on a $400,000+ loan (appraisal, title insurance, origination, recording fees). A HELOC typically has $0–$1,500 in closing costs — many lenders waive them entirely.

If you're borrowing $50,000, paying $12,000 in closing costs is a 24% upfront cost before you've spent a dollar of the actual cash. The HELOC's higher rate has to overcome a $12,000 head start to lose. At 8.5% on $50,000, that's roughly 2.8 years of interest. If you'll pay the HELOC off in under three years, the closing-cost savings alone make it the winner — regardless of the rate differential.

HELOC Rate Risk: The Variable-Rate Trap

The biggest HELOC downside is variable rates. Your payment can increase if the Prime Rate rises. In 2022–2023, Prime jumped from 3.25% to 8.5% in 18 months — HELOC payments more than doubled for many borrowers.

HELOC vs Home Equity Loan vs Cash-Out: The Three-Way Comparison

There's a third option people often forget: a fixed-rate home equity loan (HEL). It's a second mortgage like a HELOC, but you take a lump sum at closing with a fixed rate, typically 7.5%–9% in May 2026.

For a homeowner who knows the exact amount needed (e.g., $80,000 to pay off a known renovation contract) but has an ultra-low first mortgage, the fixed-rate home equity loan often beats both alternatives.

Tax Implications in 2026

Under the Tax Cuts and Jobs Act provisions still in effect through 2026, interest on HELOCs, home equity loans, and cash-out refinances is tax-deductible only if the funds are used to "buy, build, or substantially improve" the home securing the loan. Using the money for credit card payoff, college tuition, or a new car? No deduction.

Combined mortgage debt deductibility is capped at $750,000 (or $375,000 married filing separately) for loans originated after December 15, 2017. If your total debt across first mortgage plus second lien exceeds this, you can only deduct interest on the first $750,000.

Decision Framework: Run These Five Numbers

Before signing anything, calculate:

  1. Current mortgage rate — if below 5.5%, default to HELOC unless you have a compelling reason otherwise
  2. Cash needed — under $50K favors HELOC; over $150K may favor cash-out
  3. Payback timeline — under 5 years strongly favors HELOC (closing cost amortization)
  4. Variable rate tolerance — if a 50% payment increase would break your budget, choose fixed-rate options
  5. Closing costs as % of loan — if cash-out closing costs exceed 8% of the cash received, the math is broken

Frequently Asked Questions

Can I get both a HELOC and a cash-out refinance?

Technically yes, but rarely a good idea. Combined loan-to-value (CLTV) limits typically cap your total borrowing at 80–85% of home value. If you cash-out refi to 80% CLTV, you've used up your equity — no HELOC capacity remains. Most lenders also won't approve a HELOC within 6 months of a cash-out refinance because it looks like serial equity stripping.

What credit score do I need for each option?

Cash-out refinance: 620 minimum for conventional, 580 for FHA, 720+ for best rates. HELOC: 680 minimum for most lenders, 740+ for the lowest margins above Prime. HELOC underwriting is generally stricter because lenders take second-lien risk. Both require debt-to-income ratios under 43–50%.

How long does each one take to close?

HELOC: 2–6 weeks from application to first draw. Cash-out refinance: 30–60 days. HELOCs are faster because they don't require the full underwriting cycle of a new first mortgage. If you need money urgently, HELOC wins on speed too.

What happens to my HELOC if home values drop?

Lenders can freeze or reduce your HELOC credit limit if your home value declines, even on lines you haven't fully drawn. This happened to roughly 5 million American homeowners in 2008–2010. If you anticipate needing the money, draw it before a downturn rather than relying on availability later. Already-drawn balances cannot be called back, but unused capacity can be revoked with as little as 30 days' notice.

Is it ever smart to use a cash-out refinance to pay off credit cards?

Mathematically, swapping 24% credit card debt for 6.25% mortgage debt looks like a win — but you're converting unsecured debt into debt secured by your home. If you can't pay, the bank forecloses. You also lose the credit card interest deduction (which doesn't exist) but the mortgage interest from cash-out used for debt consolidation is also not deductible. Only do this if you've completely solved the spending behavior that caused the credit card debt. Otherwise you'll re-accumulate the cards within 2 years and now have both problems.
