A HELOC is a credit line secured by your home whose rate floats with the prime rate; a home equity loan is one lump sum at a fixed rate. Both borrow against the same equity and both put the house on the line. The real difference is who carries the rate risk: with the loan the lender does, and with the HELOC you do.

Most comparisons stop at “variable versus fixed.” This page measures what “variable” meant in practice, using the Federal Reserve’s prime rate month by month through the fastest run of hikes in four decades and the cuts that followed.

What each one is

A home equity line of credit (HELOC) works like a card with your house behind it. During a draw period, often 10 years, you borrow what you need, repay it and borrow again, and many lines ask only for interest. Then the draw period ends and a repayment period begins, often 20 years, in which principal and interest are both due. The rate is an index, almost always prime, plus a margin the lender sets. Under Regulation Z (12 CFR 1026.40), the lender may only change the rate by an index it does not control and the public can see.

A home equity loan is a second mortgage paid out once. The rate is usually fixed, and the payment is the same every month until the balance is gone, like a car loan with a much longer term. If rates fall you can refinance it; if they rise, nothing changes for you.

Both stack on top of your first mortgage, and lenders cap the combined balance at a share of the home’s value. For how the underlying rates are set, see interest rates rather than a repeat here.

Where they differ

Price today versus price later. The HELOC average sat 1.28 points below the 10-year loan on 4 Nov 2026. That is a discount for taking on rate risk, and the rest of this page is about what that risk looked like.

Paying for unused money. A loan charges interest on all of it at once. A line charges only on the drawn balance, which matters when the cost arrives in stages, such as a remodel paid as each contractor finishes.

The line can shrink. Regulation Z lets a lender block new draws or reduce the limit while the home’s value is significantly below the appraisal the line was based on, or if it reasonably believes a material change in your finances means you cannot keep up the payments. A loan already paid out cannot be taken back that way.

A worked example: $50,000 at today’s averages

Take $50,000 borrowed at Bankrate’s national averages for 4 Nov 2026 (Bankrate surveys $30,000 lines and loans), with nothing else changed. Your own offer depends on credit and lender; this shows the shape, not a quote.

The math is the standard loan payment: rate divided by 12, over the number of months. Two things stand out. Paid off on the same 10-year schedule, the HELOC is $33.92 a month cheaper and saves $4,070.88 of interest, but only if prime stays at 7.00%. Paying interest only for the full draw period makes the lifetime interest 3.3 times the 10-year loan’s, because none of the $50,000 shrinks for ten years.

Where is the break-even? Both repaid over 10 years, the HELOC costs about the same as the 8.77% loan if its rate averages 8.77%, which at a 0.49-point margin means prime averaging about 8.28%, 1.28 points above today. That threshold is the number to keep in mind for the history below.

The original data

What prime actually did. The Federal Reserve’s daily bank prime loan rate (FRED series DPRIME) was 3.25% at the start of 2022. It then rose 11 times, reaching 8.50% on 27 Jul 2023 and staying there until 18 Sep 2024. Six cuts followed, to 6.75% on 11 Dec 2025, and one hike on 17 Sep 2026 put it at 7.00%, still the rate in the latest data (27 Oct 2026).

What that did to a $50,000 HELOC. We added an example margin of 0.49 points, the gap between Bankrate’s 4 Nov 2026 HELOC average (7.49%) and today’s prime (7.00%), to each month’s average prime rate (FRED MPRIME), Jan 2022 to Oct 2026, 58 months, and held that margin the same throughout. Real lines reset on their own billing dates and margins vary by lender, so read the result as the shape of the risk.

• January 2022: 3.74%, so $155.83 a month in interest.
• August 2023 to August 2024: 8.99%, so $374.58 a month for 13 straight months, 2.4 times the starting payment on exactly the same balance.
• January to August 2026: 7.24%, so $301.67 a month after the cuts.
• October 2026: 7.49%, so $312.08 a month.

Over the 58 months the interest-only payments added up to $18,377.50, and the balance was still $50,000 at the end.

How rare was that rise? Measured on monthly averages since Jan 1949, prime rose 4.50 points in the 12 months from Apr 2022 to Apr 2023. The only bigger 12-month rises began in 1978, 1979 or 1980, the largest being 9.38 points from Aug 1980.

How often did prime clear the break-even? We took every month from Jan 1949 to Oct 2016 that has ten full years of data after it (814 starting months) and asked whether prime’s average over the next 120 months beat the starting rate by more than 1.28 points, the gap between today’s two averages. It did in 224 of them, 27.5%. From 1990 starts only, it did in 53 of 322, 16.5%.

That is history, not a forecast. The windows overlap heavily, so they are far from 814 separate tests, and most of the hits come from the inflation of the 1970s. What it does show is that a rise big enough to erase the HELOC’s head start has happened in real decades, not only in theory.

The payment jump when the draw period ends

The draw period hides the principal. While a line is interest-only, the payment tells you nothing about the debt. When the repayment period starts, the same $50,000 has to be paid down over whatever years are left.

At today’s 7.49%, moving to a 20-year repayment lifts the payment from $312.08 to $402.49, a 29% rise with no change in rates. Had the switch landed in the peak months at 8.99%, it would have gone from $374.58 to $449.54. Both shocks stack: a borrower who drew in Jan 2022 at $155.83 a month and reached repayment at the peak would have nearly tripled the payment.

Regulation Z requires lenders to show a historical example in the HELOC disclosures, based on a $10,000 line and the last 15 years of the index. That table is the lender’s own version of the chart above, so read it before signing.

Is the interest tax-deductible?

Only when the money goes into the house. IRS Publication 936 (2025 edition) says that, no matter when the debt was taken on, you can no longer deduct interest on a loan secured by your home to the extent the proceeds were not used to buy, build or substantially improve that home. Qualifying debt counts toward the $750,000 mortgage limit ($375,000 married filing separately), and you have to itemize.

The rule is the same for a HELOC and a home equity loan, so it does not pick a side. It does mean a HELOC used to pay off cards gets no tax help; for that use, compare against the plans on paying off debt.

Which one to use: HELOC or home equity loan?

Use the home equity loan when the amount is known and the budget is tight. A roof, a one-time bill, a fixed project quote: one sum, one payment you can plan around, and no exposure to the next Fed decision. You pay 1.28 points more at today’s averages for that certainty.

Use the HELOC when the spending comes in stages and you will repay fast. If you only draw what each phase costs and pay it back in a few years, the lower starting rate and interest on the drawn balance only both work for you, and a rate rise has little time to bite.

Use neither for a payment you could only afford at today’s rate. Before taking the line, work out the payment at prime plus two or three points. From 2022 to 2023 prime rose 5.25 points in 16 months, and the house is the collateral.

When it fails

The HELOC fails when the borrower treats the draw-period payment as the real one. The 2022 borrower who planned around $155.83 faced $374.58 19 months later, and repayment still lay ahead.

The fixed loan fails when rates fall and you do not move. Prime fell 1.75 points from Sep 2024 to Dec 2025; a fixed borrower kept the old rate unless they paid to refinance.

Both fail when the home’s value falls. A line can be frozen exactly when you wanted the cash, and either debt can leave you owing more than the house is worth if you need to sell.

Both fail on unsecured debt that comes back. Moving credit card balances onto the house turns unsecured debt into debt secured by your home; if the cards fill up again, you owe both.

Questions people ask

Is a HELOC or a home equity loan cheaper right now?

On Bankrate’s 4 Nov 2026 averages the HELOC starts cheaper, 7.49% against 8.66% to 8.77% for fixed loans. Whether it stays cheaper depends on where prime goes, which nobody knows in advance.

Why do HELOC rates change?

Because they are tied to an index, usually the prime rate, which banks move when the Fed moves its target. In the data prime changed 18 times from Mar 2022 to Sep 2026.

Can I switch part of a HELOC to a fixed rate?

Some lenders let you lock part of the balance at a fixed rate, sometimes for a fee. It is a lender feature, not a rule, so check the agreement.

What happens at the end of the draw period?

You can no longer borrow, and the balance is repaid with principal and interest, often over 20 years. On $50,000 at 7.49% that lifts the payment by 29%.
