TL;DR — Quick Verdict
- The national average HELOC adjustable rate is 7.23% as of July 17, 2026 (Curinos), while the Federal Reserve’s G.19 series puts the average 24-month personal loan APR at commercial banks at 11.40% as of February 2026 — a spread of roughly 4 percentage points.
- On a $40,000 renovation repaid over 10 years, that spread is worth approximately $10,300 in total interest, before closing costs.
- HELOC closing costs of $500–$2,000 erase the rate advantage only on small, short-term borrowing — typically under $10,000 repaid within two to three years.
- HELOC interest is deductible only if proceeds substantially improve the home securing the loan, per IRS Publication 936; the One Big Beautiful Bill Act made that restriction and the $750,000 debt cap permanent.
- Unsecured home improvement loans carry no foreclosure risk and no rate reset — a real premium worth paying when the fed funds target sits at 3.50%–3.75% with cuts uncertain.
- Borrow $25,000 or more against solid equity, take the HELOC; borrow less, need speed, or lack 20% equity, take the fixed personal loan.
American homeowners will spend a projected $518 billion on improvements and repairs by the end of 2026, according to the Leading Indicator of Remodeling Activity from Harvard’s Joint Center for Housing Studies. Most of that money is borrowed. And the choice between an unsecured home improvement loan from a lender like SoFi, LightStream, or Discover and a home equity line of credit from Bank of America, PNC, or Figure carries a four-percentage-point rate gap that compounds into five figures on a mid-size project.
That gap is not the whole story. HELOCs charge closing costs, take weeks to fund, put the house on the line, and reprice every time the Federal Reserve moves. Personal loans fund in days, cost more per dollar, and cannot cost you your home. Renovation budgets rarely account for any of this. They account for cabinets.
This analysis prices both products against verified July 2026 rate data, runs the full interest math on $10,000, $25,000, and $40,000 renovations, applies current IRS deductibility rules, and identifies the borrowing threshold where each option wins.
What Each Product Actually Costs in July 2026
Rate data diverges by source because each firm surveys a different lender panel. Curinos reported a national average HELOC adjustable rate of 7.23% on July 17, 2026, based on applicants with credit scores of at least 780 and a combined loan-to-value ratio below 70%. Bankrate’s survey of the largest home equity lenders returned 7.43% for a $30,000 HELOC as of July 15, 2026. LendingTree, which reports offers extended to its own users rather than posted rates, showed 8.23% for June 2026 originations. The honest range is 7.23% to 8.23%, and where you land depends heavily on equity and score.
Unsecured borrowing prices differently. The Federal Reserve’s G.19 Consumer Credit release recorded an average 11.40% APR on 24-month personal loans at commercial banks in February 2026. Credit unions undercut that: the National Credit Union Administration reported an average 10.64% on three-year fixed loans in its 2025 Q4 rate survey. Marketplace data tells a harsher story for anyone below excellent credit — NerdWallet’s prequalification pool showed 14.58% for borrowers scoring 720 or higher and 19.04% for the 690 to 719 band on July 1, 2026. Understanding personal loan APR by credit score matters more here than in almost any other borrowing decision.

One structural note before the math: the G.19 figure blends every credit tier at commercial banks, so it understates what a 660-score borrower will actually be quoted. The Curinos HELOC figure overstates what a typical borrower gets, since it assumes a 780 score and sub-70% CLTV. Real-world spreads are usually narrower than the headline four points.
The $40,000 Renovation: Running the Numbers
Take a kitchen remodel financed over ten years. At the Curinos HELOC average of 7.23%, a $40,000 balance amortized across 120 months carries a monthly payment of roughly $469 and total interest near $16,300. Run the same balance at the Federal Reserve’s 11.40% commercial bank average and the payment climbs to about $552, with total interest around $26,200 — a difference of approximately $9,900 in interest and $83 per month.
Closing costs narrow that gap but do not close it. HELOC origination, appraisal, and title fees typically run $500 to $2,000, though several large lenders waive them in exchange for an early-closure clawback if you shut the line within three years. Figure unavailable at publication — no federal agency publishes a national HELOC closing cost average; the range above reflects lender disclosures aggregated by consumer research firms. Subtract the high end and the HELOC still saves roughly $7,900 over the loan’s life.
Smaller balances flip the arithmetic. Borrow $10,000 over three years and the interest difference shrinks to about $650 — less than a $2,000 closing cost package. Personal loan borrowers should still check origination fees and true APR, since a 6% origination fee on an unsecured loan quietly adds $600 to a $10,000 draw and is often buried outside the quoted rate.

That last assumption is the fragile one. HELOC rates move with prime.
What Determines Your HELOC Rate — and Why It Moves
Prime rate plus a lender margin: that is the whole formula. The Wall Street Journal prime rate stood at 6.75% in July 2026, unchanged since December 2025, and the Federal Open Market Committee held its target range at 3.50% to 3.75% at its June 17, 2026 meeting. A borrower quoted 7.23% is therefore paying prime plus roughly 0.48 points. A borrower with a 680 score and 85% CLTV might be quoted prime plus 3.00 — meaning 9.75%, well above the personal loan average at a credit union.
Consider a real scenario. A homeowner in Ohio with a $310,000 home, a $190,000 mortgage balance, and a 745 credit score has $120,000 in equity. At an 85% CLTV ceiling, the maximum combined debt is $263,500, leaving a $73,500 line available. She draws $40,000 for a bathroom addition and a roof. Her margin lands at prime plus 1.25, giving her 8.00% — not the 7.23% headline, but still comfortably under any unsecured quote she received.
Here is the exposure most borrowers underweight. If the FOMC raises rates by 100 basis points over the next three years, her rate becomes 9.00% and her payment on that $40,000 balance rises by roughly $21 per month. If rates instead fall, as one cut is currently projected for 2026, she benefits automatically without refinancing. A fixed personal loan does neither. That symmetry is the actual trade, and readers weighing the broader personal loan versus HELOC cost comparison should price it deliberately rather than assume rates only fall.
Draw periods add another wrinkle. Most HELOCs allow interest-only payments for ten years before converting to a fully amortizing repayment period. Pay interest-only on $40,000 at 8.00% and you send $267 monthly while retiring zero principal — then face a payment near $485 in year eleven. Payment shock at conversion is the single most common source of HELOC distress.
HELOC vs Unsecured Home Improvement Loan: Which Is Better for a $25,000 Project?
Split the comparison across five dimensions that actually change outcomes, and the picture stops looking like a simple rate contest.
Compiled by Real Cost Report from Curinos rate data, Federal Reserve G.19, and IRS Publication 936.
Tax treatment deserves more weight than it usually gets. IRS Publication 936 permits deducting interest on home equity borrowing only when the proceeds buy, build, or substantially improve the home securing the loan — and the One Big Beautiful Bill Act made both that restriction and the $750,000 combined acquisition debt cap permanent, ending the expiration everyone had been planning around. A kitchen remodel qualifies. Repainting a bedroom generally does not. For a borrower in the 24% bracket who itemizes, deductible interest on a $25,000 HELOC at 7.23% is worth roughly $430 in year one alone.
Verdict
For a $25,000 project on a home with at least 20% equity, the HELOC wins by roughly $4,300 in interest before any tax benefit, and by closer to $5,600 for an itemizing borrower doing qualifying improvement work. Take the unsecured loan instead when the project must start within a week, when equity sits below 20%, when the work will not qualify as substantial improvement, or when a variable rate would genuinely threaten the household budget. The rate gap is real, but so is the collateral.
What Most Homeowners Get Wrong
Four errors show up repeatedly, and each one costs real money.
Treating the draw period as free money
Interest-only payments feel like a discount. Ten years of interest-only on $40,000 at 8.00% sends $32,000 to the lender while the balance stays exactly where it started. The fix: make principal payments from month one, targeting full amortization across the combined draw and repayment window.
Assuming HELOC interest is automatically deductible
The lender’s product label is irrelevant. IRS Publication 936 keys deductibility entirely to where the money went, so a borrower who draws $40,000 and spends $15,000 on a bathroom and $25,000 on credit card payoff deducts interest on $15,000 only. Keep contractor invoices and bank records tying each dollar to the property. A borrower planning to fold in old balances should model debt consolidation savings math separately rather than blending both goals into one draw.
Shopping rate without shopping fees
A 10.99% personal loan with an 8% origination fee costs more than a 13.99% loan with none, on a three-year term. The quoted rate is not the price. Confirm whether the lender deducts fees from proceeds — if so, a $25,000 request nets $23,000 and you still owe $25,000.
Ignoring prepayment terms on both sides
Several HELOC lenders claw back waived closing costs if the line closes within 36 months, functioning as a de facto exit fee. On the unsecured side, prepayment penalties by lender vary widely, and a homeowner planning to sell in two years needs that answer before signing. Read the early termination clause specifically.
Who Should Choose Which — and When Neither Fits
Equity is the first gate. A HELOC requires meaningful home equity, and most lenders cap combined loan-to-value at 80% to 85%. Buy in 2024 with 5% down and there is likely nothing to draw against, regardless of credit quality.
Choose the HELOC when three conditions hold together: you have at least 20% equity, you are borrowing $25,000 or more, and the project qualifies as substantial improvement under Publication 936. That combination captures the full rate spread plus the deduction, and the several-week funding timeline is tolerable for a planned renovation.
Choose the fixed home improvement loan when the roof is leaking now, when equity is thin, or when your household cannot absorb a payment that moves. Borrowers who need money quickly should compare same-day loan lenders and speed premiums against a two-to-six-week HELOC close — sometimes the speed is worth two extra points, sometimes it is not. Those with damaged credit should first check realistic subprime personal loan APR ranges, since a 28% unsecured quote makes the entire project worth reconsidering.
Neither product fits well in two situations. Financing under $5,000 rarely justifies either — a 0% introductory credit card handled within the promotional window usually costs less, though the personal loan versus credit card interest comparison turns sharply against cards once that window closes. And a borrower already declined once should diagnose why before reapplying; the loan denial reasons and next steps matter more than the rate, because each hard inquiry compounds the problem. Adding a co-signer’s risks and rate benefits can bridge a thin file, but it transfers real liability to someone else.
Frequently Asked Questions
Can I deduct HELOC interest if I use part of the money for something else?
Only the portion used to buy, build, or substantially improve the securing home qualifies, per IRS Publication 936. Draw $40,000 and spend $15,000 on a bathroom addition plus $25,000 on other debt, and you may deduct interest attributable to $15,000 only. The $750,000 combined acquisition debt cap — $375,000 for married filing separately — applies to your first mortgage and home equity balance together, and the One Big Beautiful Bill Act made that cap permanent.
How much can my HELOC rate rise?
HELOCs price at prime plus a margin, and prime stood at 6.75% in July 2026 with the FOMC target range at 3.50% to 3.75%. Federal law requires a lifetime cap on variable-rate HELOCs, but caps of 18% are common — far above anything you would pay today. A 100 basis point increase on a $40,000 balance adds roughly $21 to the monthly payment.
Is a fixed home equity loan a better middle ground?
Often, yes. Curinos put the national average fixed home equity loan rate at 7.36% on July 17, 2026 — just 13 basis points above the HELOC average and roughly four points below the Federal Reserve’s 11.40% personal loan figure. You get the secured rate and a fixed payment, but you take the full amount as a lump sum upfront, which is inefficient for phased projects where money is drawn over many months.
Do credit unions really beat banks on home improvement loans?
On average, modestly. The National Credit Union Administration reported an average 10.64% APR on three-year fixed loans in its 2025 Q4 survey, compared with 11.40% at commercial banks in the Federal Reserve’s February 2026 G.19 data. That 76 basis point gap saves roughly $250 on a $20,000 three-year loan. Membership requirements are usually easy to satisfy, so the comparison is worth making. Peer-to-peer platforms occasionally price lower still for strong credit profiles.
How We Researched This Article
Rate figures in this analysis come from four categories of source, each with different coverage and limitations.
Unsecured lending rates come from the Board of Governors of the Federal Reserve System’s G.19 Consumer Credit release, series TERMCBPER24NS, which measures the finance rate on 24-month personal loans at commercial banks. The most recent observation available at publication was February 2026 at 11.40%. This series is a blended average across all credit tiers and does not disaggregate by score, which means it understates costs for subprime borrowers and overstates them for prime borrowers. Credit union comparison figures come from the National Credit Union Administration Credit Union and Bank Rates report for 2025 Q4.
Home equity rates come from Curinos, a financial analytics firm whose national averages are distributed through major consumer finance publishers. Curinos figures assume a minimum 780 credit score and combined loan-to-value below 70% — a favorable profile that most applicants will not match. We cross-checked against Bankrate’s national lender survey, which returned 7.43% for a $30,000 HELOC, and against LendingTree’s originated-offer data at 8.23%. Where sources conflicted we reported the range rather than selecting a single figure.
Tax treatment reflects IRS Publication 936 and the permanent extension of the Tax Cuts and Jobs Act mortgage interest provisions under the One Big Beautiful Bill Act. Market context comes from the Leading Indicator of Remodeling Activity published by Harvard’s Joint Center for Housing Studies; we used the April 15, 2026 revised release rather than the superseded January estimate, which the Center corrected for a formula error.
All interest totals in this article are modeled, not measured. We applied standard amortization formulas to the published rates, assuming fully amortizing payments, no missed payments, no closing costs, and — for HELOCs — a static rate across the full term. That last assumption is deliberately unrealistic and is discussed in the rate-movement section. No national agency publishes an average HELOC closing cost figure, so the $500 to $2,000 range reflects aggregated lender disclosures rather than a primary statistical source, and is presented as a range for that reason. Research last conducted July 2026. All figures were verified against named primary sources before publication.
