TL;DR — Quick Verdict
- The national average HELOC rate is 7.44% as of July 29, 2026 (Bankrate) — roughly 2 to 6 percentage points cheaper than most business lines of credit, which run 8%–20% at banks and 20%–60% online.
- Closing costs typically run 2%–5% of your credit line: on a $100,000 line, that is $2,000–$5,000, though online lenders like Figure and Aven advertise $0 upfront.
- HELOC interest used for business is not deductible as home mortgage interest — it is deductible as a business expense under IRS interest tracing rules only if you document every dollar’s use.
- A HELOC vs. SBA 7(a) comparison: the HELOC is faster and cheaper to close, but the SBA 7(a) caps at 9.75% with no personal residence on the line.
- Worth it if you have strong equity, a short payback horizon, and disciplined recordkeeping; a serious mistake if the venture is unproven and your home is the only collateral.
More than 43% of mortgaged U.S. properties were equity-rich in the first quarter of 2026, according to ATTOM Data Solutions — and a growing share of owners are eyeing that equity as startup capital. A home equity line of credit lets a business owner borrow against home value at 7.44% (Bankrate’s July 2026 national average), a rate no unsecured business product can match. The catch is structural: the loan is secured by your house, not your enterprise. This report breaks down what a HELOC actually costs when used for business in 2026 — the interest math, the closing fees, the annual charges — and the interest tracing rules that determine whether the IRS lets you deduct any of it. You will see a line-by-line cost comparison against an SBA 7(a) loan rates and fees and a bank line of credit, a worked scenario on a $75,000 draw, and the specific documentation mistakes that turn a legitimate deduction into a disallowed one. Lenders named include Figure, Aven, and traditional bank HELOC providers.
What a Business-Purpose HELOC Actually Costs in 2026
Start with the rate. HELOC pricing floats above the prime rate, which sits at 6.75% as of 2026 (effective December 10, 2025, per the Federal Reserve’s H.15 release and the WSJ bank survey). Lenders typically price a HELOC at prime plus a margin of 0.50% to 1.00% for well-qualified borrowers, which is why Bankrate’s national survey put the average at 7.44% on July 29, 2026. Credit-union pricing often runs 50 to 100 basis points below that national figure.
Upfront costs are the second cost layer. Traditional bank HELOCs carry closing costs of 2% to 5% of the credit line, covering appraisal ($300–$700), origination (0.5%–1%), title search, document prep, and recording fees. On a $100,000 line, expect $2,000 to $5,000 at signing. Online lenders such as Figure and Aven advertise zero closing costs, though they may embed the difference in a higher rate or an origination fee reaching 4.99%.
Then come the recurring charges most borrowers overlook: annual fees ($0–$100), inactivity fees ($200–$500 in some agreements), and per-draw minimums ($25–$50). A business owner who draws irregularly can trigger fees a homeowner never would.

How the Interest Math Works: A $75,000 Draw Modeled
Numbers make the trade-offs concrete. Picture a consultant who opens a $150,000 HELOC and draws $75,000 to fund inventory and a hire, at the 7.44% average rate during a 10-year interest-only draw period.
Interest-only cost in year one runs about $5,580 ($75,000 × 7.44%), or roughly $465 per month. Because a HELOC is variable, that payment moves with prime. If the Federal Reserve lifts prime by 0.50%, the same balance costs $5,955 annually — a $375 jump with no change in principal. This variability is the hidden cost of a HELOC versus a fixed-rate term product, and it matters most when a business plans to carry the balance for years rather than months.
Add the upfront drag. At a mid-range 3% closing cost on the full $150,000 line, that is $4,500 paid before a dollar is borrowed. Spread over a two-year payback, closing costs alone add roughly $2,250 per year to the effective cost — pushing the true annual expense well above the headline rate. Owners weighing a revolving facility against a lump sum should model both against a line of credit versus term loan comparison before drawing.
The offsetting advantage is that you pay interest only on what you draw. Leave $75,000 of the line untapped and it costs nothing beyond any annual fee — the flexibility a term loan cannot offer.
HELOC vs. SBA 7(a): Which Is Better for Funding a Business?
The cleanest comparison is against the most common government-backed option. An SBA 7(a) loan for amounts over $350,000 caps at prime plus 3.0% — a 9.75% ceiling at today’s 6.75% prime, per the SBA’s SOP 50 10 and lender surveys. Competitive borrowers land near 9.00%–9.50%. That is higher than the 7.44% HELOC average, but the collateral structure is entirely different.
Speed and cost of entry favor the HELOC. A HELOC can close in weeks with $2,000–$5,000 in fees; an SBA 7(a) involves a longer underwriting process, guarantee fees, and heavier documentation. The 7(a) also spreads repayment across terms up to 25 years, easing monthly cash flow that a 10-year HELOC draw period compresses.
Risk allocation is where they diverge most. A HELOC secures the debt with your primary residence; default risk runs straight to your home. An SBA 7(a) is secured by business assets and a personal guarantee, but not necessarily your house — though large loans may require a lien on real estate you own. For owners weighing what a signature commits them to, the mechanics of a personal guarantee obligation and risk deserve close reading, as does a side-by-side SBA microloan versus community bank loan for smaller needs.
Verdict
For a fast, short-horizon need under $150,000 where you hold strong equity and can repay within two to three years, the HELOC’s 7.44% rate and quick close win on total cost. For a larger, longer-term investment — or any situation where you cannot stomach your home on the line — the SBA 7(a) at a 9.75% cap is the safer structure despite its higher rate and slower funding. The deciding question is not the rate; it is which asset you are willing to lose.
The Tax Reality: When HELOC Interest Is Actually Deductible
Many owners assume HELOC interest is deductible because it once was. Under the Tax Cuts and Jobs Act — made permanent by the One Big Beautiful Bill signed July 4, 2025 — HELOC interest is deductible as home mortgage interest on Schedule A only when proceeds buy, build, or substantially improve the home securing the loan. Business use fails that test entirely.
The deduction survives through a different door: interest tracing. Under Temporary Treasury Regulation §1.163-8T and IRS Notice 89-35, deductibility follows the destination of the funds, not the loan type. Trace $75,000 of HELOC proceeds into an active trade or business you materially participate in, and the interest becomes deductible as a business expense on Schedule C — or on Schedule E for a rental or investment property. This deduction is not subject to the $750,000 mortgage-debt cap because it is treated as business, not home, interest.
One limitation applies. Business interest deductions fall under IRC Section 163(j), which the OBBBA restored to the more favorable EBITDA-based calculation of Adjusted Taxable Income starting in 2026, letting businesses deduct more interest under the 30% limitation. A small business exemption still applies to most owners below the gross-receipts threshold. Owners layering multiple debts should map the full cost against a broader merchant cash advance APR calculation and an invoice factoring effective rate to see which financing carries the lowest after-tax cost.
What Most People Get Wrong About Business HELOCs
Three mistakes recur, and each carries a specific, avoidable consequence.
Mistake 1: Commingling funds and destroying the tax trace
The error is dumping HELOC draws into a personal checking account used for groceries and bills. The consequence is that the interest tracing rule collapses — once funds are commingled, the IRS can disallow the business deduction entirely. The correct action is to deposit every HELOC draw into a dedicated business account and log each expenditure with receipts, contracts, and bank statements.
Mistake 2: Opening a HELOC for the deduction rather than the economics
Owners chase the write-off and ignore that the borrowing must make sense before taxes. The consequence is paying 7.44% interest to recover a fractional deduction — a net loss. The correct action is to treat any deduction as a secondary benefit and justify the loan on cash-flow math alone.
Mistake 3: Ignoring variable-rate risk on a multi-year balance
Because a HELOC floats with prime, a business carrying a large balance for years faces rising payments the moment the Fed hikes. The consequence is a payment shock that a fixed-rate loan would have prevented. The correct action is to reserve HELOCs for short-payback needs or model a rate-rise scenario before drawing. Newer owners without a credit history should also review startup loan requirements and alternative costs and begin building business credit from zero so future financing does not depend on home equity.
Who Should Use a HELOC for Business — and Who Should Not
Conditional logic sorts the good fits from the dangerous ones. A HELOC works when you hold substantial home equity, need under roughly $150,000, plan to repay within two to three years, and keep disciplined books that preserve the interest trace. It suits an established owner bridging a seasonal gap or funding a specific, revenue-generating purchase where the payback is visible.
It works against you in the opposite conditions. If the venture is unproven, if your home is the family’s only significant asset, or if repayment stretches beyond the 10-year draw window into an amortizing phase you have not budgeted for, the structure converts business risk into housing risk. A failed business loan damages business credit; a defaulted HELOC can cost you the house.
Owners who want to keep the business and the home financially separate have alternatives worth pricing. A dedicated business line of credit runs 8%–20% at banks — higher than a HELOC but ring-fenced from your residence. Compare that structure against revenue-based financing cost structure and equipment financing versus leasing total cost for asset-specific needs. The right choice depends less on the lowest rate than on how much of your personal balance sheet you are prepared to put at risk.
Frequently Asked Questions
Is HELOC interest tax deductible if I use it for my business?
Not as home mortgage interest, but potentially as a business expense. Under IRS interest tracing rules (Temp. Treas. Reg. §1.163-8T and Notice 89-35), if you trace HELOC proceeds into an active trade or business, the interest is deductible on Schedule C or Schedule E — outside the $750,000 mortgage cap. You must document every dollar’s use; commingling funds can void the deduction.
What is the average HELOC rate for 2026?
The national average HELOC rate is 7.44% as of July 29, 2026, according to Bankrate’s survey of the largest home equity lenders. HELOC rates float above the prime rate, which is 6.75% in 2026, typically at prime plus 0.50% to 1.00%. Credit unions often price 50 to 100 basis points below the national average.
How much does it cost to open a HELOC?
Traditional bank HELOC closing costs run 2% to 5% of the credit line — roughly $2,000 to $5,000 on a $100,000 line, covering appraisal, origination, title, and recording fees. Online lenders such as Figure and Aven advertise zero closing costs, though they may charge higher rates or an origination fee up to 4.99%.
Is a HELOC or SBA 7(a) loan cheaper for business?
By headline rate, the HELOC is cheaper: 7.44% versus an SBA 7(a) cap of 9.75% (prime + 3.0% on loans over $350,000). But the HELOC secures the debt with your home, while the SBA 7(a) uses business assets and a personal guarantee. The HELOC closes faster and cheaper; the SBA 7(a) offers longer terms and keeps your residence off the line.
How We Researched This Article
This analysis draws exclusively on primary and named institutional sources verified in July 2026. HELOC rate data comes from Bankrate’s national HELOC survey, which reported a 7.44% national average as of July 29, 2026, based on offers from the nation’s largest home equity lenders. The prime rate of 6.75% (effective December 10, 2025) was confirmed against the Federal Reserve’s H.15 Selected Interest Rates release and the Wall Street Journal bank survey.
Tax treatment reflects the interest tracing framework in Temporary Treasury Regulation §1.163-8T and IRS Notice 89-35, the mortgage-interest provisions of the Tax Cuts and Jobs Act as made permanent by the One Big Beautiful Bill (signed July 4, 2025), and the Section 163(j) business interest limitation. SBA 7(a) rate caps were verified against the SBA’s Standard Operating Procedure 50 10 and cross-checked with LendingTree’s SBA rate documentation. Closing cost ranges were compiled from Rocket Mortgage and lender fee disclosures.
The $75,000 draw scenario is modeled, not measured: it applies the verified 7.44% average to a hypothetical balance to illustrate interest-only carrying cost and rate sensitivity, and actual costs will vary by lender margin, credit profile, and prime-rate movement. Fee ranges represent national spreads and may not reflect region- or lender-specific pricing. Where sources reported differing figures, we used the most recent primary or institutional value and noted the range. This analysis was last conducted in July 2026. All figures were verified against named primary sources before publication.
