Introduction

A cash-out refinance replaces your existing mortgage with a larger one and hands you the difference in cash. A HELOC (home equity line of credit) is a revolving credit line secured by your home that you can draw from, repay, and redraw during its draw period. Both convert your home equity into cash, but they price that cash very differently — and in 2026 the gap between them is wide enough to matter.

In this guide, we compare Cash-Out Refinance vs HELOC: Which Is Cheaper in 2026? using current rate data, real closing-cost numbers, the TCJA tax rules, and the repayment math. The answer is not a single winner: it depends on how much you borrow, how long you plan to hold the debt, and what your existing mortgage rate is.

Current Rates: Cash-Out Refinance vs HELOC (2025–2026)

After the Federal Reserve's rate cuts through 2025, 30-year fixed mortgage rates settled in the 6.5% to 7.5% range in early-to-mid 2026, with 15-year terms running roughly half a point lower. Lenders typically price a cash-out refinance 0.25 to 0.5 percentage points above a rate-and-term refinance because the larger loan and cash-out feature add risk, so plan on the upper end of that range.

HELOCs, by contrast, are variable-rate products tied to the prime rate, which sat near 7.5% after the 2025 cuts. Most lenders quote a margin of prime plus 0.5 to 1.5 points, putting the typical HELOC at 8% to 9% as of 2026. That is roughly 1 to 2 points above a cash-out refinance — on a $100,000 balance, every point is $1,000 a year in extra interest. HELOC rates can also move the month after any Fed decision, so today's quote is not the rate you will pay in year two or three.

Closing Costs: 2–5% vs $0–$500

The refinance's lower rate comes with a heavy upfront price. Closing costs on a cash-out refinance typically run 2% to 5% of the new loan amount: origination fees around 0.5% to 1%, an appraisal at $300 to $600, title insurance and settlement fees of $500 to $1,000, plus recording and credit report charges. On a $250,000 loan, that is $5,000 to $12,500 in cash out of pocket or rolled into the balance.

A HELOC is dramatically cheaper to open. Because the lender keeps the existing first mortgage intact and often uses an automated valuation instead of a full appraisal, typical HELOC closing costs are $0 to $500, and many lenders absorb them entirely to win the business. Watch for the two hidden fees instead: an annual fee of $50 to $100 and an early termination fee if you close the line within the first two to three years, which can be several hundred dollars.

Tax Deductibility: Both Subject to TCJA Rules

Neither product gets a blanket deduction. Under the Tax Cuts and Jobs Act (TCJA), mortgage interest is deductible only when the debt is used to buy, build, or substantially improve the home, and only on combined acquisition debt up to $750,000 for married couples filing jointly ($375,000 if married filing separately).

That rule hits both options equally — with one important difference. A cash-out refinance commingles your existing mortgage with the cash-out portion, so you must trace the funds: if a $200,000 refinance pays off a $150,000 old mortgage and $50,000 of cash-out, and only $20,000 of the cash funds a kitchen remodel, then just $170,000 of the $200,000 debt carries deductible interest. A HELOC is usually a separate, labeled account, which makes the tracing cleaner — and if you use the money for a vacation or debt consolidation, the interest is simply not deductible under either product.

Repayment Structure

A cash-out refinance is one new amortizing mortgage over 15 or 30 years, with a fixed payment that includes principal and interest from the very first month. You know the payment forever, but you also reset the clock on the entire balance — the money you already owed starts a fresh 30-year term, which dramatically increases total interest even when the rate is lower.

A HELOC has a 5- to 10-year draw period followed by a 10- to 20-year repayment period. During the draw, payments are often interest-only; when repayment begins, the payment jumps to include principal, typically 50% to 100% higher. The flexibility is real — you borrow only what you need and pay interest only on what you draw — but the payment shock is the classic trap. Stress-test the repayment-period payment before you borrow a dollar.

Cash-Out Refinance vs HELOC: Comparison Table

When the Cash-Out Refinance Wins

The refinance wins when you need a large lump sum, want a locked rate, and plan to hold the debt long enough to recover the closing costs. Run the breakeven: on a $50,000 draw with a 1.5-point rate gap, the HELOC costs about $750 more per year, but the refinance's 3% closing costs on a $250,000 loan come to $7,500 — roughly a 10-year breakeven before the refinance gets cheaper. If you are consolidating debt and keeping the new mortgage for the long haul, the fixed rate and lower APR make it the safer structural choice.

When the HELOC Wins

The HELOC wins when the amount is small, the timing is uncertain, or your current mortgage rate is low. Borrowing $20,000 for a phased renovation, paying it off in three years, and keeping a 3.5% first mortgage untouched is a decisive HELOC case: the $200 to $500 in upfront costs and roughly $900 in extra interest over the life of the draw beat paying $4,000 to $8,000 in closing costs and re-pricing your entire mortgage at 7%.

The Bottom Line for 2026

Cash-out refinance vs HELOC is not a rate contest; it is a cost-and-term contest. The refinance is cheaper per dollar only after years of repayment, and it raises the rate on money you already owed. The HELOC is more expensive per dollar but cheap to open, flexible, and leaves your first mortgage alone. As of 2026: HELOC for borrowing under roughly $50,000 or under five years; cash-out refinance for large, long-term borrowing when you can absorb the closing costs and want payment certainty.
