HELOC vs Cash Out Refi: Which Taps Your Equity Smarter?

Your existing mortgage rate is the single most important variable when choosing between a HELOC and a cash-out refinance. If your current mortgage is at 4% or below, keep it and take a HELOC for the cash you need, because the cash-out refi forces you to refinance the entire balance at today's rates, wiping out a below-market asset. If your current mortgage is at 6.5% or higher, a cash-out refi can produce a lower blended rate and may be the smarter move.

The decision is rarely about the absolute rate on the new debt. It's about what happens to the rest of your mortgage. A HELOC adds a second loan on top of your existing mortgage, leaving your first lien untouched. A cash-out refi replaces your entire mortgage with a new, larger one at current market rates. For the roughly 60% of U.S. homeowners sitting on sub-4.5% mortgages locked in during 2020–2022, that replacement is enormously expensive.

This guide works through both options on a concrete scenario ($100,000 in equity to access on a $600,000 home) and runs the cost under different existing-mortgage assumptions. We also cover closing costs, rate risk, tax treatment, and the common mistakes that cost borrowers the most. If you're deciding between a heloc vs cash out refi, start by finding your current mortgage rate on your most recent statement. That one number points you toward the right answer.

HELOC vs Cash Out Refi: How the Two Products Work

Understanding the structural difference between these products is essential before running any numbers.

HELOC (Home Equity Line of Credit)

A HELOC is a revolving line of credit secured by your home, structured similarly to a credit card. The lender extends a maximum credit limit, and you draw against it as needed during a "draw period" (typically 10 years). During the draw period, you pay interest only on the amount actually drawn.

• Rate: Variable, tied to the prime rate. The current formula is typically prime plus a margin of 0.5 to 2.0 points. With prime at 6.75%, top-tier HELOC rates run approximately 8.20% as of June 2026. You can compare current HELOC offers by rate and lender.
• Closing costs: Typically $0–$2,000. Many HELOCs have no closing costs at all if you keep the line open for a minimum period (usually 3 years).
• Time to close: 2–4 weeks.
• Payment structure during draw period: Interest only on the drawn balance. If you draw $100,000 at 8.50%, the monthly interest payment is roughly $708. You can pay down principal anytime, then re-borrow up to the limit.
• Repayment period: After the draw period ends (typically year 11), the HELOC converts to amortizing payments over the remaining 10–20 years. Monthly payment increases substantially at that point.
• What it does NOT touch: Your existing first mortgage. The HELOC is a second lien; the original mortgage stays as it was.

Cash-Out Refinance

A cash-out refi is a new mortgage that replaces your existing mortgage entirely. The new loan amount equals your existing mortgage balance plus the cash you want to take out. The lender pays off the old mortgage and disburses the difference to you.

• Rate: Fixed (most common) or adjustable. Current 30-year fixed cash-out refi rates run approximately 6.72%, typically 15–30 basis points above purchase-mortgage rates of 6.72%.
• Closing costs: Typically 2–5% of the new loan amount. On a $400,000 cash-out refi (paying off $300,000 mortgage and disbursing $100,000), closing costs of $8,000–$20,000 are common.
• Time to close: 30–60 days.
• Payment structure: Standard amortizing mortgage. Fixed monthly principal and interest payment over the new loan term (typically 30 years, reset).
• What it touches: Everything. Your old mortgage is paid off and replaced with a new one. Whatever rate you had, even if it was 3% from a 2021 origination, is gone.

The Scenario Math: $100,000 Draw on a $600,000 Home

Three scenarios capture most readers' situations. Common assumptions across all three:

• Home value: $600,000
• Cash needed: $100,000
• Borrower: 740+ credit score, 35% debt-to-income ratio, owner-occupied primary residence
• 30-year loan terms throughout

What differs is the existing mortgage balance and rate. This is where the heloc vs cash out refi decision actually lives.

Scenario A: You Have a 3.5% Mortgage From 2021

Consider a homeowner named Sarah who bought in 2021 and refinanced at a great rate. Her current mortgage:

• Balance remaining: $320,000
• Rate: 3.50%
• Monthly principal and interest: $1,438
• Remaining term: 26 years

Option 1: HELOC for $100,000:

• HELOC rate: 8.20%
• Monthly HELOC interest (draw period): ~$708
• Original mortgage payment: $1,438 (unchanged)
• Total monthly payment: $2,146
• Closing costs: $0–$2,000

Option 2: Cash-Out Refi to $420,000 at 6.95%:

• New mortgage: $420,000 over 30 years at 6.95%
• Monthly principal and interest: $2,776
• Closing costs: $10,000–$15,000
• Total monthly payment: $2,776 (about $630 more per month)

The HELOC wins by approximately $630 per month (over $7,500 per year) for as long as the draw period lasts. On a 10-year draw, that's $75,000+ in cash-flow advantage. The cash-out refi is the wrong answer here.

This pattern is dominant for anyone who locked in a sub-5% mortgage during 2020–2022. For those borrowers, the cash-out refi is almost always the wrong choice. The HELOC preserves the asset they have: a below-market fixed-rate mortgage.

Scenario B: You Have a 6.5% Mortgage From 2024

• Balance remaining: $380,000
• Rate: 6.50%
• Monthly principal and interest: $2,402

HELOC total monthly payment: $3,110 | Cash-out refi total monthly payment: $3,172

The gap narrows to just $62 per month. Secondary factors (rate volatility tolerance, closing cost sensitivity, and how long you plan to stay) now drive the decision. For most readers in this scenario, the HELOC is still slightly favored because the closing-cost differential ($12,000–$18,000 vs. near-zero) is large.

Scenario C: You Have a 7.2% Mortgage From Late 2023

For example, consider David and Maria, who purchased their home when rates peaked. Their current mortgage:

• Balance remaining: $390,000
• Rate: 7.20%
• Monthly principal and interest: $2,651

HELOC total monthly payment: $3,359 | Cash-out refi total monthly payment: $3,238

The cash-out refi wins by $121 per month, about $1,450 per year. Over 30 years, that's $43,500 in cumulative savings even after closing costs. Because the existing mortgage rate (7.20%) is higher than the cash-out refi rate (6.95%), David and Maria benefit from refinancing the existing balance to the lower rate on top of accessing the equity.

Dollar-Impact Ladder: How Borrowing Amount Changes the Math

The size of your equity draw shifts the break-even between a heloc vs cash out refi. Here's how monthly interest-only HELOC payments compare at different draw amounts, using a current HELOC rate of 8.20%:

At smaller draw amounts ($10K–$50K), cash-out refi closing costs are a punishing percentage of the amount borrowed. The HELOC is almost always the better choice for draws under $50,000 regardless of your existing mortgage rate. At $100,000, the closing costs become more proportional, and the decision depends on your existing rate as shown in the scenarios above.

The Decision Framework: Choose HELOC If… / Choose Cash-Out Refi If…

This framework summarizes the heloc vs cash out refi choice:

Choose the HELOC if:

• Your current mortgage rate is below 5%; protecting that rate is worth more than any other factor
• You need flexible, ongoing access to funds (draw and repay as needed)
• You plan to sell or move within 3–5 years (avoids large closing costs)
• You expect to repay the borrowed amount within 5–10 years
• You can absorb potential rate increases on the variable HELOC

Choose the cash-out refi if:

• Your current mortgage rate is above 6.75%; you improve your rate on the existing balance while accessing cash
• You want a single, fixed monthly payment with no rate surprise risk
• You plan to stay in the home 10+ years (closing costs amortize over a longer period)
• You want to consolidate a first and second mortgage into one loan
• You prefer predictability over flexibility

This is especially important if you're someone who already feels stretched by monthly housing costs: the HELOC's variable rate could push you past comfortable limits if the Fed raises rates, while the cash-out refi locks in certainty.

Marketing-Hook Deconstruction: "Low Monthly Payment" Claims

Lenders advertising cash-out refinances often lead with the headline monthly payment, something like "Access $100,000 at just $2,776/month." That number looks manageable because it spreads repayment over a fresh 30-year term. But the hook obscures three realities:

1. You're resetting the clock. If you had 26 years left on your mortgage, the cash-out refi restarts at 30 years. You've added 4 years of payments, and on a larger balance.
2. You're repricing your entire balance. The "low monthly payment" doesn't mention that your existing $320,000 at 3.5% just became $420,000 at 6.95%. The payment on the existing portion alone jumped from $1,438 to roughly $2,112.
3. Closing costs are buried. The $12,000–$18,000 in fees is often rolled into the loan balance, meaning you're paying interest on the closing costs for 30 years.

The HELOC's marketing hooks are subtler but also deserve scrutiny. "Interest-only payments" during the draw period sounds appealing, but it means you're not reducing principal. When the draw period ends and amortization kicks in, the monthly payment can double or triple. Plan for that transition before you draw; most borrowers don't.

Always request the full Loan Estimate from the CFPB's standard form before committing to either product. It shows the true cost including fees, rate, and total interest paid over the life of the loan.

Where Each Option Wins and Falls Short

HELOC: Pros

• Preserves your existing mortgage rate: the single biggest advantage for sub-5% borrowers
• Near-zero closing costs: no large upfront fee
• Flexible draw and repayment: borrow only what you need, pay back and re-borrow
• Faster closing: 2-4 weeks vs. 30-60 days for a refi
• Interest potentially tax-deductible if funds are used for home improvements (consult a tax professional; see IRS guidance on home equity debt)

HELOC: Cons

• Variable rate risk: if the Fed raises rates, your payment rises. A move from 3.75% to 5.50% on the fed funds rate could push HELOC rates to 9.5-10.5%, adding ~$158/month on a $100,000 balance
• Repayment shock: interest-only payments during the draw period jump to fully amortizing payments after 10 years
• Second lien position: some lenders restrict HELOCs or charge higher rates for second-position loans
• Temptation to over-borrow: revolving access can lead to drawing more than planned

Cash-Out Refi: Pros

• Fixed rate for 30 years: complete payment predictability
• Single monthly payment: simplifies budgeting vs. managing two separate loans
• Rate improvement possible: if your existing rate is above today's market, you save on the full balance
• Potentially lower rate than a HELOC for the new cash: current cash-out rates of 6.72% vs. HELOC rates of 8.20%

Cash-Out Refi: Cons

• Destroys a low-rate mortgage: the most costly drawback for sub-5% borrowers
• High closing costs: $12,000-$18,000 on a $400K+ loan is common
• Resets your loan term: 30 years starts over, increasing total interest paid
• Slow closing process: 30-60 days with full underwriting
• Inflexible: you receive the cash once and cannot re-borrow

How to Decide Between a HELOC and a Cash-Out Refi

Follow these steps to make the right choice for your situation:

1. Find your current mortgage rate. Check your most recent mortgage statement or log into your servicer's portal. This single number determines which direction the math leans. If it's below 5%, you can likely stop here: the HELOC is almost certainly the better option.
2. Calculate the monthly cost of both options. Use the SwitchWize mortgage calculator to model a cash-out refi at today's rate of 6.72% on your new total balance. Compare that to your current mortgage payment plus estimated HELOC interest on the draw amount.
3. Get Loan Estimates from at least three lenders. Request formal Loan Estimates (not just quotes) for both a HELOC and a cash-out refi. Compare the total closing costs, APR, and monthly payments side by side. The CFPB's Loan Estimate explainer walks you through reading the form.
4. Stress-test the HELOC rate. Ask yourself: if HELOC rates rose 2 full points, could I still afford the payment? If not, the fixed-rate certainty of a cash-out refi may be worth the higher upfront cost.
5. Factor in your time horizon. If you plan to sell within 3–5 years, the HELOC's low closing costs give it a strong edge. If you're staying 15+ years, the cash-out refi's closing costs amortize over enough time to soften the impact.
6. Confirm tax deductibility with a professional. Under current tax law, interest on home-secured debt is deductible only if the funds are used to buy, build, or substantially improve the home. Using HELOC or cash-out refi funds for debt consolidation, education, or other purposes makes the interest non-deductible. Don't assume; verify.

The Variables That Shift the Answer

How Long Will You Keep the Home?

If you plan to sell within 3–5 years, the closing costs of a cash-out refi become a much larger percentage of effective cost. A $15,000 closing cost on a $100,000 draw is 15%; over 5 years, that's 3% per year in amortized cost. The HELOC's near-zero closing cost wins decisively for short holds. If you plan to stay 15+ years, the closing cost amortizes enough that its impact softens.

What's the Plan for the Borrowed Money?

If the $100,000 is for a one-time use (home renovation, business launch), either product works. If the $100,000 is for ongoing access over years (college tuition, medical expenses, business cash flow), the HELOC is structurally superior. You only pay interest on the amount drawn, and you can pay back and re-borrow.

If you're a homeowner planning a major renovation, our home improvement financing guide breaks down additional options.

Are You Planning to Pay It Down Quickly?

If you expect to repay the $100,000 within 3–5 years (from a bonus, asset sale, or income increase), the HELOC's interest-only structure during the draw period works in your favor. A cash-out refi locks you into amortizing payments and a 30-year term.

Other Options to Consider

Home Equity Loan (Fixed-Rate Second Lien)

A home equity loan is a fixed-rate, fixed-term second lien, essentially a cash-out refi structure applied to a second mortgage. Rates as of June 2026 are approximately 8.20%, slightly higher than a HELOC's current rate but with the rate fixed for the life of the loan. Best for borrowers who want a fixed rate on the new debt without giving up their low-rate primary mortgage. We compare the two directly in HELOC vs home equity loan.

Personal Loan

For draws under $50,000, an unsecured personal loan can be competitive. Rates today are typically 8–14% for 700+ credit borrowers, comparable to a HELOC for shorter terms. The upside: no lien on your home. The downside: shorter terms (3–7 years) and higher monthly payments. For $100,000, home-equity-secured options usually win. See our personal loan comparison for current rates.

The Mistakes That Cost the Most

Cash-out refinancing a sub-5% mortgage. The single most expensive mistake in home-equity decisions. A homeowner with a 3.5% mortgage who cash-out refis to 6.95% on the entire balance pays approximately $700–$1,000 more per month than necessary for the entire life of the new loan. Over 30 years, this is a six-figure cost.

Treating HELOC interest as deductible without verifying use. Under current tax law, HELOC interest is deductible only if the funds are used to buy, build, or substantially improve the home that secures the loan. Using HELOC funds for debt consolidation, education, or other purposes makes the interest non-deductible. The IRS updated guidance after the 2017 tax law changed the rules, and many borrowers still operate on outdated assumptions.

Ignoring the HELOC repayment shock. The HELOC's interest-only payment during the draw period (years 1–10) is small. When the draw period ends, the loan amortizes over the remaining 10–20 years, and the monthly payment can double or triple. Plan for that transition before you draw.

Underestimating cash-out refi closing costs. Online quotes often show only the rate, not the closing costs. On a $400,000 cash-out refi, $12,000–$18,000 in costs is normal but feels surprising in the closing documents. Always get a full Loan Estimate before committing.
