Should I Use a HELOC to Pay Off Credit Card Debt?

If you're carrying a few thousand dollars on credit cards at 20-something percent, and you've built up real equity in your home, you've probably had the thought: what if I just move this debt somewhere cheaper? A home equity line of credit (HELOC) at around 9% instead of 22% sounds like an obvious win.

Sometimes it is. Sometimes it quietly makes things worse. The difference comes down to a few things about your situation — and one habit. Let's walk through it honestly, with real numbers, so you can judge your own case.

What you're actually doing

Using a HELOC to pay off cards doesn't erase the debt — it movesit, and changes what's backing it. Right now your card debt is unsecured: if everything fell apart, the worst the card company can do is damage your credit and send it to collections. A HELOC is secured by your house. Move the debt there and you've traded a lower rate for a real risk — miss enough payments and the lender can foreclose.

That's not a reason to never do it. It's the reason to be honest about whether you can handle the new payment before you sign. The upside is the rate: credit cards routinely charge 18–26%, while a HELOC is usually single digits. On a balance you can't clear in a month or two, that gap is real money.

The math, with real numbers

Say you owe $15,000 on cards at 22%, and you can put $400 a month toward it. Paying it off on the cards, that takes roughly five years and about $10,000 in interest— and that's only if you never charge another dollar. Pay just the minimum instead, and you're looking at 20-plus years.

Move that same $15,000 to a HELOC at 9%and keep paying $400 a month, and it's gone in under four years for roughly $2,600 in interest. Same payment, same discipline — about $8,000 less interest, and out of debt sooner. That, in a sentence, is the case for doing it.

Whether a HELOC is even on the table depends on your equity. Lenders let you borrow up to a combined loan-to-value (CLTV) limit — often 80–90% of your home's value, minus what you still owe on the mortgage. If your home is worth $500,000 and you owe $300,000, an 85% limit means a line of up to about $125,000 — far more than enough for a $15,000 balance.

The trap that turns this into a mistake

Here's the part that sinks people. You move $15,000 off the cards and onto the HELOC. The cards now show a $0 balance — and they feel like free money again. Over the next two years you drift back to $8,000 in card debt. Now you owe the $15,000 HELOC and $8,000 on cards at 22%: more total debt than you started with, and part of it is secured by your house.

This isn't a rare edge case — it's the single most common way a HELOC payoff goes wrong. The rate savings are real, but they only matter if the cards stay at zero. If you're not certain they will, the lower rate is a trap, not a tool.

Other things people get wrong

Assuming the rate is fixed. Most HELOCs carry a variable ratetied to the prime rate. The 9% you start with can climb if rates rise — and unlike a fixed loan, your payment moves with it. Budget as if the rate could be a couple of points higher than today's.

Ignoring closing costs and fees.Some HELOCs carry appraisal, origination, or annual fees. On a modest balance, those can eat into the interest you're saving — compare the real, all-in cost, not just the headline rate.

Coasting through the interest-only period.Many HELOCs let you pay interest-only for the first several years. That keeps the payment low but doesn't reduce the balance, and the payment jumps when the repayment period begins. If you consolidate onto a HELOC, make sure you're actually paying down principal — not just servicing it.

So — should you?

For most people in this exact situation — a steady income, card debt at genuinely high rates, real equity in the home, and honest confidence you won't run the cards back up — the math favors moving the debt to a lower rate and killing the 22% first. The interest savings are large and real.

But don't do it if any of these three things is true:

1. Your income is shaky, or the payment would stretch you.You're putting your home on the line now, not just your credit score. Unsecured debt is survivable in a crisis; a secured debt you can't pay is a foreclosure risk.

2. You're not sure the cards will stay at zero.If there's a real chance you'll run them back up, this move can leave you worse off. Be honest with yourself — the trap is common for a reason.

3. The rate isn't much lower after fees, or it's variable and a rise would hurt.If a fixed-rate personal loan gets you a similar rate without putting your house on the line, that's often the safer trade.

If you're unsure, that's a good reason to slow down. A fixed-rate personal loan, a 0% balance-transfer card, or simply attacking the highest-rate card with the avalanche method can get you out of high-interest debt without secured-debt risk.
