HELOC vs Home Equity Loan: The Side-by-Side Decision Guide

If you bought a house any time before 2022, you almost certainly have far more equity than you realize. ICE Mortgage Monitor's March 2026 data puts national tappable equity — the amount homeowners could borrow against while keeping at least 20% equity — at roughly $11 trillion.^[1] That is more than every American owes on every credit card and every auto loan combined.

There are two mainstream ways to tap it without selling the house. A home equity line of credit (HELOC) is a revolving line — like a giant secured credit card — with a variable interest rate tied to the Wall Street Journal prime rate. A home equity loan (often called a HEL or "second mortgage") is a fixed-rate installment loan: lump sum at closing, equal payments for 5 to 30 years.

The marketing pages make them sound interchangeable. They are not. The difference between variable and fixed rate, between revolving and installment, between interest-only-then-balloon and full amortization, between "no closing costs as long as you keep it open three years" and "2% to 5% of the loan amount today," produces measurably different total costs and measurably different cash-flow shapes. Pick the wrong one and you can pay tens of thousands more for the same dollars of borrowed equity.

This guide walks the decision in full. We compare both products against the live 2026 rate environment, run the math on a $55,000 kitchen renovation under both products, walk through what happens to a HELOC borrower when the Fed tightens mid-draw, explain when a cash-out refinance actually beats a HELOC, and close with an 8-item checklist you can act on this week. When you are ready to run your own numbers, the CalcLeap HELOC calculator and home equity loan calculator do the arithmetic.

What separates them in one paragraph

A HELOC is a revolving, variable-rate, open-end credit line. You're approved for a maximum, you draw what you need, you pay interest only on what you drew, and the rate floats with the prime rate. A home equity loan is a non-revolving, fixed-rate, closed-end installment loan. You take the full amount at closing, the rate is locked, and the payment never changes. Both are second-lien mortgages, both use your home as collateral, both let the lender foreclose on default, both are governed by the same TCJA interest-deductibility rules,^[2] and both give you a three-business-day right of rescission after closing.^[3]

The side-by-side, by dimension

Twelve dimensions distinguish the two products. The table below is the entire decision tree on one page — every other section in this guide expands one row.

The 2026 rate environment, in numbers

Both products are second-lien mortgages, so they price off the same risk profile. Both are nonetheless tied to different underlying benchmarks, and the spread between them tells you something about where lenders think rates are going.

All rates verified June 3, 2026 against Bankrate's national lender survey and Freddie Mac PMMS for the week ending May 14, 2026. Individual rate offers depend on credit score, CLTV, occupancy, and lender margin.

The Federal Open Market Committee held its target range at 3.50%–3.75% at the April 28–29, 2026 meeting on an 8–4 vote — the most divided FOMC since October 1992.^[7] That leaves the WSJ prime rate at 6.75% (federal funds upper bound + 3 percentage points^[8]). The four dissenters favored a 25-basis-point cut, so the rate path implied by the May 2026 dot plot has more downside than upside for the rest of the year. A HELOC borrower who locks in today is effectively betting that the dissenters win the next two meetings; a home equity loan borrower is accepting the current rate as final.

How a HELOC actually works (the parts the brochure skips)

A HELOC has two phases: the draw period (usually 10 years) and the repayment period (usually 15 to 20 years). During the draw period you can borrow and repay against the line as many times as you like, like a credit card. The minimum payment during draw is typically interest-only on the average daily balance. At the end of the draw period — usually exactly 120 months after origination — the line closes to new advances and the outstanding balance amortizes over the remaining 15 to 20 years.

The interest rate is set at closing as WSJ prime rate + margin. The margin is fixed; the prime rate moves. In June 2026 a typical investment-grade borrower might be offered prime + 0.50% = 7.25%, but some lenders advertise prime + 0% promotional rates for the first six months.^[9] Most HELOCs include a floor (often 4%) and a lifetime cap (often 18%) disclosed at closing per TILA §1026.40.^[10]

Worked example: you draw $50,000 against a $100,000 HELOC priced at prime + 0.50% in June 2026. Prime is 6.75%, so your rate is 7.25%. Interest-only monthly payment = $50,000 × 7.25% ÷ 12 = $302.08. If you draw another $25,000 next month for a renovation phase 2, your balance becomes $75,000 and the next month's payment rises to $453.13. The line responds to your actual usage — and to Fed policy. If the FOMC cuts 25 bp at the June 16–17 meeting, your July payment falls about $10 per $50,000 drawn.

The end-of-draw cliff

The hidden risk of the HELOC structure shows up exactly 120 months after closing. Your interest-only minimum vanishes and the lender begins amortizing the balance over the remaining repayment-period months.

Take that same $50,000 outstanding balance at end of draw. The line converts to a 20-year fully amortizing loan at the then-current rate. Assume rates have held at 7.25%: the new payment is $50,000 × r·(1+r)^n / ((1+r)^n − 1) with r = 7.25%/12 = 0.006042 and n = 240, which gives $395.45. The interest-only payment was $302.08; the amortizing payment is $395.45 — a 31% increase. If the prime rate has drifted up over the decade — say to 9% — the payment becomes $449.86, a 49% jump in one billing cycle. The CFPB issued a 2014 supervisory alert specifically about this end-of-draw payment shock after the wave of 2003–2005 HELOCs reset around 2014.^[11]

How a home equity loan actually works

A home equity loan is conceptually identical to a first mortgage, just in second-lien position. You apply, the lender appraises the home and pulls credit, you close, and the entire approved amount is wired to your account on day one. The rate is fixed, the term is fixed (most commonly 10, 15, or 20 years), and the monthly payment is computed at closing using the standard amortization formula.

Where M is the monthly payment, P is the principal, r is the monthly rate (annual rate ÷ 12), and n is the number of payments. Worked example: a $50,000 home equity loan at 7.36% for 15 years (180 months). Monthly rate r = 7.36% ÷ 12 = 0.006133. Payment = $50,000 × 0.006133 × (1.006133)¹⁸⁰ / ((1.006133)¹⁸⁰ − 1) = $50,000 × 0.006133 × 3.0181 / 2.0181 = $458.78 per month. Total interest over 15 years = $458.78 × 180 − $50,000 = $32,580. The payment never changes. If you lose your job in month 137 of a 180-month term, the payment is still $458.78. Same if the Fed cuts rates by 200 basis points — your locked rate stays at 7.36%.

Closing costs and the "no-cost" HELOC

Home equity loans are full second-lien mortgages and carry the full settlement-process cost stack: lender origination fee (often 1% of loan amount), title search ($150–$400), title insurance ($300–$800), appraisal ($400–$700), recording fee ($25–$250), credit report ($25–$75), and any state mortgage tax. On a $50,000 loan this typically totals $1,500–$2,500 (3%–5% of loan amount) — and lenders generally do not waive it.

HELOCs are different. Because the lender keeps the line on its books, doesn't sell it into a mortgage-backed security, and can pull the line for cause if your equity disappears, many large lenders waive all third-party closing costs. The catch is the early-closure fee (sometimes called an "account termination fee" or "reimbursement of waived fees"). Read the disclosure carefully — most are structured as "if you close the HELOC within 36 months of origination, you reimburse the lender up to $500 of waived fees" or similar. The fee makes economic sense for the lender because the waived closing costs were the cost of acquiring you as a customer; it makes the "no cost" HELOC effectively a 36-month commitment.

The TCJA tax rules everyone gets wrong

Before 2018 you could deduct interest on up to $100,000 of "home equity debt" used for any purpose. That deduction is gone. The Tax Cuts and Jobs Act, signed December 22, 2017, rewrote IRC §163(h)(3) to eliminate the separate home-equity-debt category and consolidate all home-secured debt under one rule: interest is deductible only if the borrowed money is used to buy, build, or substantially improve the home that secures the loan.^[2] The IRS calls this "acquisition indebtedness." The total cap is $750,000 ($375,000 if married filing separately) for loans originated after December 15, 2017 — or $1 million ($500,000 MFS) for loans originated before that date.

The form of the loan does not matter. A HELOC used to buy a roof is acquisition debt and the interest is deductible (subject to the cap). A home equity loan used to pay off credit cards is home-equity debt for non-acquisition purposes and the interest is not deductible. The IRS made this explicit in Publication 936 starting with the 2018 edition and has not relaxed it since.^[2]

If you're itemizing in 2026, the standard deduction is $15,000 single / $30,000 MFJ — meaning the home-mortgage-interest deduction only matters if your itemized total exceeds those thresholds. About 90% of taxpayers take the standard deduction post-TCJA, so the interest deductibility argument is moot for most borrowers. Run the numbers before assuming HELOC interest will reduce your taxes; for most filers it will not.

Three case studies that show when each one wins

Case 1: The Olsons — $55,000 kitchen renovation, one-shot

Profile. The Olsons own a $620,000 home in suburban Minneapolis. They have $200,000 left on a 3.25% fixed-rate first mortgage taken out in 2021. Combined household income $182,000, credit score 780. They have a single signed contractor estimate for a complete kitchen tear-out at $55,000, scheduled to start August 1, 2026.

The two options at June 2026 rates.

Why the home equity loan wins this one. The Olsons know the exact amount, they know exactly when they need it, and they value payment certainty. The HEL's $504.66 payment is just $172 higher than the HELOC's interest-only minimum but locks in the rate. If they take the HELOC and prime rises 100 bp over the next decade — well within the historical normal range — they pay $6,300 more in interest and face a 31% payment shock at end of draw. The home equity loan eliminates both risks. The $1,750 in closing costs amortizes to under $10 per month over the 15-year term and recovers in the first interest-rate cycle.

The 3.25% first mortgage matters. The Olsons should not consider a cash-out refinance even at the lower 6.61% cash-out rate, because the rate on their $200,000 first mortgage would jump from 3.25% to 6.61% — costing roughly $6,700 of extra interest per year just on the existing balance. The cash-out refi math only works when the current first-mortgage rate is at or above market rates. The HELOC and home equity loan both preserve the 3.25% rate.

Case 2: Daniel — $80,000 unknown-cost gut renovation, payment-sensitive

Profile. Daniel owns a $480,000 house, $180,000 first-mortgage balance at 5.875% (taken out in 2024), credit score 740. He's planning a phased renovation: master bathroom this summer ($28,000), basement next spring ($35,000), kitchen the year after ($17,000). The contractor told him the bathroom number is firm but the basement number depends on whether the joists need sistering — a $12,000 swing.

Why the HELOC wins this one. Daniel's costs are uncertain in timing and in amount. The HELOC structure pays him for that uncertainty in two ways: (a) he only pays interest on what he has actually drawn, so he is not amortizing the basement money during the year before he draws it; (b) he keeps optionality — if the kitchen project gets postponed indefinitely, he never draws that portion of the line.

The math at prime + 1.00% = 7.75% June 2026 rate, $100,000 line, $28,000 drawn for bathroom: month-1 interest-only payment = $28,000 × 7.75% ÷ 12 = $180.83. The next April, after the basement is finished, balance is $63,000 and payment rises to $407. If Daniel had taken an $80,000 home equity loan up front to cover the full renovation budget, his payment from day one would be $80,000 × 0.007360 × (1.00736)¹²⁰ / ((1.00736)¹²⁰ − 1) ≈ $952/mo on a 10-year fixed term — and he would be paying interest on $52,000 he hasn't yet spent.

The risk Daniel accepts. If the FOMC reverses course and raises 100 basis points over the next 24 months, his rate climbs to 8.75% and his payment on the $63,000 balance jumps from $407 to $459. Daniel should explicitly stress-test his cash flow against a "rate up 150 bp" scenario before signing.

Case 3: The Rodriguezes — $35,000 to consolidate credit card debt

Profile. Combined income $128,000, $35,000 in credit card debt across four cards at an average APR of 22.5%, monthly minimum payments of about $1,250. Their $410,000 home has a $230,000 first mortgage at 4.5% from a 2022 origination. Credit scores in the low 700s.

Why neither home equity product is obviously right. A $35,000 home equity loan at 7.36% for 10 years has a payment of $412/mo and total interest of $14,440, versus the credit cards' implied $48,500+ in interest if paid via minimums. The savings are real. But there are three things to consider before they sign:

1. The interest is not tax-deductible. Debt consolidation fails the "buy, build, or substantially improve" TCJA test. They get zero tax benefit from the home equity loan even if they itemize.
2. The collateral changes character. Their credit card debt is unsecured. The bank cannot take their house if they miss a card payment. Converting to a home equity loan secures the same debt with their primary residence. If they lose income in a recession, the credit card lenders would have offered a hardship workout; the home equity lender forecloses.
3. The behavior risk. The CFPB's research on home-secured debt consolidation finds that 30%–40% of borrowers who consolidate credit card debt into a home loan run the credit cards back up to roughly the original balance within 5 years, ending up with both debts.^[12] If the Rodriguezes do not freeze the cards or close some of them after the consolidation, they end up worse off, not better.

The verdict. If the Rodriguezes are confident they will not re-load the cards and they can stomach the secured-debt risk, a fixed-rate home equity loan at 7.36% beats 22.5% credit card debt by an enormous margin. If either condition is uncertain, a 0% balance-transfer card or a 36-month personal loan at 12% may be the better tool even though the headline rate is higher. The home is not a piggy bank; it is the floor of their financial life.

How lenders decide how much to give you

The constraining number for home equity borrowing is the combined loan-to-value ratio (CLTV): the sum of your first mortgage balance and the new home equity product, divided by the current appraised value of your home. Most lenders cap CLTV at 80% or 85%; aggressive credit unions go to 90% and a handful of programs reach 95% for borrowers with high credit scores.

Worked example: a $500,000 home, $300,000 first mortgage. At an 85% CLTV cap, your maximum new home equity borrowing = $500,000 × 0.85 − $300,000 = $125,000. At 90% it rises to $150,000. At 95% it rises to $175,000. Note the leverage in that calculation: every 5 percentage points of allowed CLTV adds $25,000 of borrowing capacity on this profile.

The appraisal matters. Most home equity lenders use either a desktop appraisal (free, based on automated valuation models) or a drive-by appraisal ($150–$300) rather than the full interior appraisal common on first-mortgage purchases. If your home's tax-assessed value lags actual market value — common in slow-revaluation jurisdictions — ask for a comparable-sales analysis at application.

When a cash-out refinance beats both

A cash-out refinance is a third option that's worth mentioning specifically because the marketing aimed at home equity borrowers often conflates it with HELOC and home equity loan offers. A cash-out refi replaces your existing first mortgage with a new, larger first mortgage; you walk away with the cash difference. The rate is whatever the current 30-year first-mortgage rate is, plus a small cash-out add-on (~25 basis points per Freddie Mac historical data).^[6]

Cash-out wins on three specific profiles:

• Your current first mortgage rate is above market. If you took out your mortgage at 7.5% in late 2023 and current rates are 6.36%, cash-out lets you refinance the existing balance to a lower rate and extract equity in one transaction. The rate reduction on the existing balance often pays for the cash-out cost.
• You want one payment, not two. A HELOC or home equity loan stacks a second monthly bill on top of your first mortgage. A cash-out refi keeps it to one.
• You want a 30-year amortization on the new borrowing. Home equity loans typically max out at 20 years; HELOCs amortize over 15–20 years after draw. A cash-out refi at 30 years has the lowest monthly payment of the three, though the highest total interest.

Cash-out loses when your current first-mortgage rate is below today's market rate. Every dollar of acquisition balance you refinance pays a rate premium for the rest of the term. A homeowner with a 3% mortgage from 2021 who cash-out refis to 6.61% to extract $50,000 has paid roughly $36,000 of extra interest over 30 years on the existing $200,000 balance just for the privilege of the extraction — a cost that dwarfs the $32,000–$36,000 interest on the new $50,000.

Your three-day right to cancel — and when it doesn't apply

Both HELOCs and home equity loans on your principal residence are subject to a federal three-business-day right of rescission. The rule comes from the Truth in Lending Act §125 as implemented in Regulation Z §1026.23 (closed-end home equity loans) and §1026.15 (open-end credit, including HELOCs).^[3] If you change your mind for any reason, you can rescind the loan and the lender must return all fees, including the appraisal and origination fee.

The clock starts after the latest of three events:

1. You sign the credit agreement.
2. You receive your final Truth-in-Lending disclosures (the Closing Disclosure for most consumer mortgages).
3. You receive two copies of the notice describing your right of rescission.

You must notify the lender in writing (e-mail counts at most lenders, certified mail is safer) before midnight of the third business day. Sunday and federal holidays don't count as business days; Saturday does count under Reg Z. If the lender fails to provide proper disclosures, the rescission window extends to three years from closing — a powerful consumer protection that has voided lender claims long after the fact.^[3]

Qualifying — what underwriters actually look at

Home equity products use a tighter version of the standard mortgage underwriting box. Five variables drive the decision:

• Credit score. Most large banks set a 680 floor for any home equity product; the best rates require 740+. Credit unions sometimes go to 660. Below 660 you'll either be denied or routed to a much higher rate tier.
• Debt-to-income ratio (DTI). The total of all your monthly debt payments (first mortgage P+I+T+I, new home equity payment, car, student loans, minimum credit card payments) divided by gross monthly income. The CFPB's Qualified Mortgage rules cap DTI at 43% for QM-eligible first mortgages;^[13] home equity underwriters generally use 45%–50%.
• CLTV. Discussed above. 80%–85% is the common cap.
• Stable income. Most lenders want two years of documented income at the current source. Self-employed borrowers need two years of Schedule C or K-1 returns plus year-to-date P&L.
• Equity cushion. Even within the CLTV cap, lenders prefer to leave 15%–20% of unborrowed equity. A 95% CLTV approval at a 720 credit score and 35% DTI is rare; the same profile at 80% CLTV is routine.

Plan on supplying: most recent two pay stubs, two years of W-2s or 1099s (Schedule C/K-1 if self-employed), two months of bank statements, current mortgage statement, property tax bill, and homeowners insurance declaration page. Self-employed borrowers should expect two years of complete federal tax returns. Allow 30 to 45 days from application to closing for most home equity loans; HELOCs sometimes close in 15–25 days at large national banks because the line is easier to underwrite.

Six mistakes that cost real money

1. Taking the HELOC for one fixed-amount expense. The flexibility costs you 7-to-25 basis points and exposes you to rate risk. If you know the amount, take the fixed-rate product.
2. Ignoring the end-of-draw payment shock. A 31%–49% payment increase in a single billing cycle wrecks budgets. Run the projection at application.
3. Assuming HELOC interest is always deductible. Since 2018 the test is the use of funds, not the form of the loan. Credit card consolidation gets zero deduction.
4. Refinancing a low-rate first mortgage to cash-out. Every dollar of the existing balance pays a rate premium. Use HELOC or home equity loan instead.
5. Closing a "no-cost" HELOC within 36 months. The waived closing costs become payable as the early-closure fee. Plan to keep the line at least three years or accept the recoupment fee at application.
6. Securing unsecured debt without changing behavior. The CFPB finds 30%–40% of credit-card-to-home-equity consolidators re-load the cards within five years.^[12] Close at least half the accounts at consolidation.

Action checklist — what to do this week

1. Estimate your tappable equity. Pull a current Zillow or Redfin valuation, subtract your first mortgage balance, multiply the home value by 0.85 and subtract the first mortgage. That number is your realistic borrowing capacity.
2. Define the use of funds in writing. One sentence — "$X for [purpose]." If the purpose passes the "buy, build, substantially improve" test, the interest may be deductible. If it doesn't, don't plan on the deduction.
3. Pull three rate quotes. Your existing mortgage servicer, one large bank (Bank of America, Chase, US Bank), and one credit union. Compare rate, margin (HELOC), closing costs, early-closure fee, lifetime cap, and DTI cap on the same day so the rate environment doesn't move between quotes.
4. Run both products through our calculators. Use the HELOC calculator for variable-rate scenarios and the home equity loan calculator for fixed-rate. Compare 5-year and 15-year total interest at the rate you'll actually be quoted.
5. Stress-test against a 200-bp rate increase. If you're considering a HELOC, calculate the payment with prime at 8.75% rather than 6.75%. If that payment doesn't fit, downsize the line or take the fixed loan.
6. Get the end-of-draw amortized payment in writing. Ask the HELOC lender for a written projection at the assumed rate and assumed end-of-draw balance. Confirm it fits your retirement-era cash flow.
7. Confirm your right of rescission. At closing you should receive two copies of the rescission notice for a HELOC or home equity loan on your principal residence. If you don't, do not sign — the clock cannot start without the notice.
8. Plan the debt-payoff escape route. If you're consolidating credit card debt, close or freeze at least half the cards the day the consolidation funds. Set a calendar reminder one year out to verify the cards haven't crept back up.
