Using a HELOC to Pay Off Credit Cards: Lower Rate, Higher Stakes

By LoansGenerator.com · Last updated October 26, 2026

A home equity line of credit (HELOC) usually costs less than credit card debt, because your house secures it. That same fact is the risk. Card debt that you cannot pay leads to collections and credit damage. HELOC debt that you cannot pay can lead to foreclosure.

This page walks through what a HELOC is, how the cost compares with your cards and with an unsecured personal loan, the specific ways a HELOC can go wrong for debt payoff, and when an unsecured loan is the better fit. Figures come from the Federal Reserve, the CFPB, the FTC and the IRS, checked on October 26, 2026. For the full range of consolidation paths, see our debt consolidation guide.

Key takeaways

• A HELOC turns unsecured card debt into debt secured by your home. The CFPB: "If you fall behind or can't repay the loan on schedule, you could lose your home."
• HELOC rates are usually variable, built from an index such as the prime rate plus a lender margin. The prime rate was 7.00% on October 22, 2026, per the Federal Reserve.
• Interest-only draw periods can make the payment look small while the balance barely moves.
• The IRS says HELOC interest is deductible only if the money is used to buy, build or substantially improve the home. Paying off cards does not qualify.

How does a HELOC work?

The CFPB defines a HELOC as "an 'open-end' line of credit that allows you to borrow repeatedly against your home equity," where equity is "the value of your home minus the amount you owe on your mortgage." It has two phases:

• Draw period. You can borrow up to your limit. The CFPB gives 10 years as an example. Some plans allow interest-only payments during this period, "which means that you pay nothing toward the principal," per the CFPB's HELOC booklet.
• Repayment period. "Monthly payments are often significantly higher once you enter repayment," the CFPB says. Some plans require a balloon payment of the whole balance at once.

The rate is usually variable. The CFPB booklet explains that a variable rate "generally has two parts: the index and the margin," and that common indexes include "the U.S. prime rate." The Federal Reserve's H.15 release shows the bank prime loan rate at 7.00% on October 22, 2026. Your HELOC rate would be that index plus whatever margin your lender adds, and it moves when the index moves.

Lenders' equity, credit score and debt-to-income rules for opening a line are in HELOC requirements.

HELOC vs credit cards vs personal loan: what does $20,000 cost?

Here is $20,000 of card debt under four approaches. Card and personal loan rates are the Federal Reserve G.19 averages for August 2026, the third-quarter reading in the October 7, 2026 release: 22.36% on card accounts assessed interest, and 11.90% on 24-month personal loans at commercial banks. G.19 publishes no 60-month personal loan rate. For the HELOC we assume prime (7.00%) plus a 1-point margin, so 8.00%, and show what happens if it rises to 10.00%. That margin is an assumption for illustration; lenders set their own.

Figure: Interest only, excluding fees and closing costs. Rates from Federal Reserve G.19 (August 2026, release of October 7, 2026) and H.15 (prime 7.00%, October 22, 2026); the 1-point HELOC margin is an assumption.

What the numbers say:

• Repaid on a five-year schedule, the HELOC is cheapest on interest, by $2,301.00 against the personal loan at these rates. Closing costs reduce that gap. The CFPB says closing costs on a home equity loan "can be hundreds or thousands of dollars."
• A 2-point rate rise costs $1,164.60 more over five years on this balance, and the borrower does not control it.
• The interest-only path is the expensive one. Paying $133.33 a month feels easy, but after 10 years you still owe the full $20,000. Total interest reaches $36,149.20, more than five times the personal loan. Most of the low-rate advantage disappears when the repayment is stretched out.

What are the real risks of using home equity for card debt?

The CFPB lists them directly on its consolidation page: "using a home equity loan to consolidate credit card debt is risky. If you don't pay back the loan, you could lose your home in foreclosure." The FTC says the same about consolidation loans that use your home as collateral. The specific risks:

1. Foreclosure replaces collections. Unpaid cards damage credit and can lead to a lawsuit. An unpaid HELOC puts the house at stake.
2. Variable rates. The CFPB notes that with a variable rate, "your monthly payments may change even if you don't draw more money."
3. Payment shock at repayment. Payments "are often significantly higher" when the draw period ends, and some plans require a balloon payment. The CFPB booklet: "If you are unable to pay the balloon payment in full, you could lose your home."
4. Going underwater. The CFPB warns that borrowing against equity "could put you at risk for being 'underwater' on your home if your home value falls," which can make it harder to sell or refinance.
5. The line can be frozen. HELOCs "generally permit the lender to freeze or reduce your credit line if the value of your home falls" or your finances worsen, per the CFPB booklet.
6. Your emergency cushion is gone. The CFPB points out that equity used for cards "may not be available in an emergency or for expenses like home renovations or repairs."
7. The cards are still open. The CFPB warns that "taking on new debt to pay off old debt may just be kicking the can down the road." If the cards fill up again, you have card debt and a lien on your home.

Ask yourself the CFPB's question. The CFPB HELOC booklet asks: "Am I comfortable with the worst-case scenario, where I could lose my home?" If the honest answer is no, stop here and look at unsecured options.

Is HELOC interest tax deductible when you pay off cards?

No. The IRS answers this exact question in its FAQs. Asked about a home equity loan used "to pay off personal debts," the IRS says interest on a loan secured by your home may be deductible "only if the proceeds of the loan are used to buy, build, or substantially improve the taxpayer's residence." Publication 936 repeats it: interest on home equity loans and lines of credit is deductible "only if the borrowed funds are used to buy, build, or substantially improve the taxpayer's home that secures the loan." Do not count a tax deduction in your comparison if the money goes to cards. If you are weighing a HELOC for a renovation instead, our home improvement loan vs HELOC page covers that case.

For personal loans requested through the form below:

Representative example. For a $5,000 loan at a 10% APR over 36 months, the monthly repayment would be $161.34. Over the term, the total repayment would amount to $5,808.24, with $808.24 in interest. The loan terms range from 6 months to 12 years, with APRs between 5.99% and 35.99%. The exact rate you receive depends on factors like your creditworthiness, loan size, and repayment schedule. Better rates are typically offered to those with excellent credit.

When does an unsecured personal loan fit better?

An unsecured personal loan usually costs more in interest than a well-priced HELOC, but it keeps your home out of the deal. It tends to fit better when:

• Your job or income is less stable, so the risk of missing payments is real.
• You have little equity, or home values in your area have been falling.
• You want a fixed rate and a fixed end date with no draw period to tempt re-borrowing.
• The balance is modest. For a mid-size balance, see what a $25,000 personal loan typically involves.
• You are weighing other secured sources too. Borrowing from retirement savings has its own trade-offs, covered in our page on using a 401(k) loan to pay off credit cards.

A HELOC can make sense when you have stable income, substantial equity, a plan to repay on a short fixed schedule (not interest-only), and closed or frozen card accounts so the balances cannot return.

If you do use a HELOC, how do you protect yourself?

• Get three estimates. The CFPB booklet includes a worksheet for comparing offers on fees, margins, draw period and repayment terms.
• Ask about the index, the margin and the cap. The CFPB's earlier HELOC booklet says variable-rate plans secured by a dwelling must by law have a ceiling on how far the rate can rise. Know that number.
• Ask about a fixed-rate option. The CFPB notes some HELOCs let you convert a balance to a fixed rate, which is "typically higher than the variable rate" but more predictable.
• Pay principal from day one. Set your own payment to clear the balance in five years or less, even if the plan only requires interest.
• Use your right to cancel. If the home is your principal dwelling, Regulation Z generally lets you cancel a new line in writing until midnight of the third business day after it opens, and the lender must return the fees you paid to open it.

Common questions

Is it smart to use a HELOC to pay off credit cards? It can lower interest, but it moves the risk onto your home. The CFPB calls using home equity to consolidate card debt "risky." It fits best with stable income, plenty of equity and a short repayment plan.

Is a HELOC or a home equity loan better for debt consolidation? The CFPB booklet describes a home equity loan as fixed-rate with equal payments that pay off the whole loan, and a HELOC as typically variable with a draw period. For a one-time payoff, the fixed schedule removes the interest-only trap. Both put your home at risk.

What is the HELOC rate right now? It depends on the lender's index and margin. Many use the prime rate, which was 7.00% on October 22, 2026, per the Federal Reserve. Your rate would be the index plus the lender's margin.

Can I deduct HELOC interest if I use it for credit cards? No. The IRS limits the deduction to money used to buy, build or substantially improve the home securing the loan.

What happens if I can't pay my HELOC? The CFPB says you could lose your home. Contact the lender immediately. The FTC also points homeowners to free HUD-approved housing counselors.
