Is a HELOC Cheaper Than a Fixed Home Equity Loan for a $40,000 Renovation?

A homeowner planning a $40,000 renovation usually checks one number first: which loan has the lower rate today. Right now that is the home equity line of credit, not the fixed-rate home equity loan. But a HELOC's rate is variable for the full repayment period, while a fixed home equity loan locks in today's rate for the life of the loan. Financed over 10 years, that difference can flip the real cost in either direction. So the honest way to read the comparison is not "which rate is lower" but "what is the one number that separates them actually made of." That number is $3,256.70, and the rest of this post takes it apart.

Key takeaways

  • As of November 4, 2026, the national average HELOC rate is 7.49%, versus 8.77% for a 10-year fixed home equity loan, per Bankrate's lender survey.
  • On a $40,000, 10-year loan, a HELOC that never changes rate costs $56,951.80 total versus $60,208.50 for the fixed loan — a $3,256.70 edge for the HELOC.
  • If the HELOC's rate rises just 2 percentage points after 24 months (to 9.49%), its 10-year total cost becomes $60,322.60 — slightly more than the fixed loan, erasing the entire advantage.
  • The break-even isn't about which rate is lower today. It's about whether you believe HELOC rates will stay within roughly 1 percentage point of today's level for the next decade.

$3,256.70 — where the HELOC's head start comes from

Every argument for the line of credit in this scenario reduces to one figure: on a $40,000 balance repaid over 120 months, the HELOC's starting rate saves $3,256.70 against the fixed loan. It is a real number, it is arithmetic rather than opinion, and it is also the most fragile number in the comparison. Taking it apart in four pieces — the two rates it rests on, the two totals it is the difference of, the assumption that holds it still, and the single rate move that spends it — is more useful than any verdict.

The two rates the number is built on

The rates used are Bankrate's national average, $30,000-loan-amount survey figures published for the week of November 4, 2026: 7.49% for a HELOC and 8.77% for a 10-year fixed home equity loan. Actual offers vary by credit score, combined loan-to-value ratio, and lender; Bankrate's own published range for HELOCs that week was 3.99% to 11.95%. Both averages were still the published figures when this post was re-checked on November 6, and the home equity loan survey had moved the other way from the HELOC that week: the 5-year average slipped three basis points to 8.66% while the 10- and 15-year averages each dipped two, to 8.77% and 8.76%.

Side A: the fixed loan at 8.77%

At a fixed 8.77% APR, a $40,000 loan amortized over 120 months carries a monthly payment of $501.74. Over the full term, the borrower pays $20,208.50 in interest, for a total cost of $60,208.50. That payment and that total never change, regardless of what happens to interest rates elsewhere in the economy. The actual rate a specific borrower is offered will move up or down from that 8.77% average depending on credit score, combined loan-to-value ratio (the first mortgage plus the new loan, measured against the home's value), and the lender's own pricing; Bankrate's published range for the 10-year product that week ran from 6.25% to 10.54%.

Side B: the HELOC at 7.49%, if it never moves

At 7.49% APR on the same $40,000 balance and 120-month schedule, the monthly payment is $474.60. Total interest over 10 years is $16,951.80, for a total cost of $56,951.80 — $3,256.70 less than the fixed loan. This is the number that makes the HELOC look like the obvious choice, and if the rate truly never changed for 10 years, it would be. In practice, most HELOCs also charge only interest during an initial draw period, often the first 10 years, before a separate repayment period begins; the full-amortization model used here is a simplification chosen specifically to isolate the rate-risk question, not a description of how every HELOC is structured.

The two totals, side by side

ScenarioMonthly paymentTotal interestTotal cost of $40,000
Fixed home equity loan, 8.77%$501.74$20,208.50$60,208.50
HELOC, flat at 7.49% for 10 years$474.60 (then unchanged)$16,951.80$56,951.80
HELOC, +2 points after year 2$474.60, then $509.71$20,322.60$60,322.60

The spread between the best case and worst case for the HELOC is $3,370.80 — roughly 8% of the amount borrowed — and it depends entirely on a single rate move that is well within the range HELOC rates have already covered in recent years. The fixed loan has no spread at all; its cost on day one is its cost in year ten.

What the $3,256.70 quietly assumes

A fixed home equity loan and a HELOC both let a homeowner borrow against equity without touching the first mortgage. The difference that matters for a 10-year renovation loan is not the starting rate — it's what kind of rate each product carries for the full term. A fixed home equity loan's rate is locked at closing and never moves again. A HELOC's rate is tied to the prime rate and can move every time the Federal Reserve changes the federal funds rate, for as long as a balance is outstanding. The Consumer Financial Protection Bureau's consumer guide on HELOCs describes this directly: the rate "can change over time," which is the entire source of the risk modeled below.

Assume a homeowner needs $40,000 for a kitchen or bathroom renovation and wants it fully paid off in 10 years (120 months), the same term Bankrate publishes an average rate for on both products. To make the two loans comparable, this model treats the HELOC as if it amortizes on the same fixed 120-month schedule as the home equity loan, rather than using a typical HELOC's interest-only draw period followed by a separate repayment period. That assumption understates a real HELOC's flexibility (a borrower could pay interest-only for years and owe more later) but it isolates the one variable this article is about: the cost difference that comes from a variable rate versus a fixed one, holding the repayment schedule constant.

Two of those assumptions deserve to be stated plainly, because both of them cut in the borrower's favor. The model gives the HELOC a fixed 120-month amortization it would not normally have, which removes the risk that an interest-only draw period leaves a large balance outstanding later. And it compares survey averages rather than two quotes from the same lender on the same day, which is the only comparison a borrower can actually act on. If anything, then, $3,256.70 is a generous version of the HELOC's head start.

The rate move that spends the entire $3,256.70

HELOC rates have moved by more than 2 percentage points within a two-year window before; Bankrate's own weekly tracking shows the national average HELOC rate climbing for five straight months into this November. To test the downside, this model holds the HELOC at 7.49% for the first 24 payments, then steps the rate up to 9.49% for the remaining 96 months, re-amortizing the remaining balance so the loan still pays off in the original 120-month term.

PhaseRateMonthsPaymentInterest paid in phase
Phase 17.49%1–24$474.60$5,586.18
Phase 29.49%25–120$509.71$14,736.42

Total interest across both phases is $20,322.60, for a total cost of $60,322.60 — $114.10 more than simply taking the fixed home equity loan on day one. A rate increase of just 2 points, two years into a 10-year loan, is enough to erase the HELOC's entire starting advantage and leave the borrower slightly worse off than if they had locked a fixed rate from the start.

What the number cannot price

If a homeowner is confident they can pay off the balance quickly — within a year or two, before a rate increase has time to compound — the lower HELOC rate is close to a free option, since there isn't enough time for rate risk to matter much. For a renovation loan meant to be paid down slowly over a full decade, the calculation changes: the fixed home equity loan is effectively buying insurance against rate risk, and the question is whether roughly $3,250 of potential savings is worth giving that insurance up. A homeowner who already carries a low fixed-rate first mortgage and wants to avoid refinancing it may still prefer a HELOC for its flexibility to draw only what is needed, but that flexibility is a separate benefit from the rate math above, not a reason the rate math changes.

One more factor belongs in the decision but isn't part of the cost table: interest on either a HELOC or a home equity loan is only deductible on a federal return when the loan proceeds are used to buy, build, or substantially improve the home that secures the debt, under rules the IRS has applied since the 2017 tax law changes. A $40,000 kitchen or bathroom renovation generally qualifies as a substantial improvement; using the same loan to consolidate credit card debt or cover a vacation generally would not. That distinction doesn't change which product costs less, but it can change the after-tax gap between them for a borrower who itemizes deductions, and it's worth confirming with a tax professional before assuming either loan's interest is deductible.

FAQ

Is a HELOC always cheaper than a home equity loan?

Not necessarily over a long repayment term. A HELOC's rate is usually lower at the start because it's variable, but a fixed home equity loan's rate cannot rise later. Whether the HELOC stays cheaper depends on where rates go over the life of the loan.

How much would HELOC rates need to rise to erase the savings on a $40,000, 10-year loan?

Based on the rates in this article, a roughly 2-percentage-point increase starting in year two is enough to make the HELOC's total cost exceed the fixed loan's, as shown in the side-by-side table above.

Can a homeowner convert a HELOC to a fixed rate later?

Some lenders offer a fixed-rate conversion option on part or all of a HELOC balance, often for a fee or a slightly higher locked rate. This isn't modeled above; a borrower considering it should ask their specific lender whether that option exists and what it costs.

Does this math include closing costs or appraisal fees?

No. This article isolates the interest-rate variable only. Closing costs and fees differ by lender and loan amount and should be added to either option's total cost separately.

Why use a 10-year, $30,000 rate survey for a $40,000 loan?

Bankrate's published national averages are tied to a $30,000 reference loan amount and, for home equity loans, specific terms (5, 10, and 15 years). This article uses the 10-year figure as the closest published benchmark; an actual $40,000 quote may differ slightly by lender.

Tip: Before committing to either option, it helps to run the amortization yourself and track the monthly payment month by month. A financial calculator makes the rate-change scenarios easy to test, and a budget planner keeps the renovation draw schedule and the payments side by side.

Correction November 6, 2026: the paragraph on the fixed-rate option originally gave Bankrate's 6.00%–10.49% average rate range, which is the range Bankrate publishes for the 5-year home equity loan, alongside the 10-year 8.77% average used in every calculation here. The 10-year product's published range that week was 6.25%–10.54%, and the text now says so. Source: Bankrate, Current Home Equity Loan Rates, survey of November 4, 2026.
