Credit card debt
Should I Use a HELOC to Pay Off Credit Card Debt?
Cutting 22% interest to 9% sounds like free money. The catch: the debt moves onto your house. Here is the honest math and a 4-question test.
Short answer: a HELOC can save you thousands, and it can also cost you your house. Both things are true, which is why this decision deserves more than a rate comparison.
A HELOC (home equity line of credit) lets you borrow against your home at rates far below any credit card. Use it to pay off the cards and your interest rate can drop by more than half overnight.
But you are not paying off debt. You are moving it, from unsecured debt where the worst case is credit damage, to secured debt where the worst case is foreclosure. Whether that trade makes sense comes down to four questions.
The 4-question test
1. Is the spending fixed?
Balances stopped growing months ago, not last week.
2. Is your income stable?
A missed HELOC payment risks your home, not just your score.
3. Is the rate gap big?
22% to 9% is worth it. 22% to 18% is not worth the risk.
4. Do you have a payoff schedule?
A fixed amortizing payment, never interest-only minimums.
Four yeses: the math is on your side. Any no: fix that first.
The math: what a HELOC actually saves
Here is $20,000 of card debt with the same $600 monthly payment, on the cards versus moved to a HELOC:
| Where the debt lives | Debt-free in | Total interest |
|---|---|---|
| Credit cards at 22% APR | ~4 yrs 4 mos | ~$11,200 |
| HELOC at 9% | ~3 yrs 3 mos | ~$3,100 |
Same $600 monthly payment on a $20,000 balance. Illustrative rates; HELOC rates are usually variable.
Roughly $8,000 saved and a year of your life back. That is the honest case for a HELOC, and it is a strong one. Which makes it easy to skip the fine print where most people get hurt.
The three ways this goes wrong
The re-spend trap
The HELOC zeroes out the cards, the cards feel usable again, and within a year or two the balances are back, on top of the HELOC payment. This is the most common failure, and it ends with double the debt and your house attached to half of it. If the spending is not already fixed, a HELOC funds the next round of it.
Interest-only minimums
Most HELOCs let you pay only interest during the draw period, often 10 years. It feels affordable. It is also a treadmill: a decade of payments and you still owe every dollar of principal. Set your own fixed amortizing payment from day one, like the $600 in the table above.
Your house becomes the collateral
Card debt cannot take your home. HELOC debt can. A layoff, an illness, or a divorce hits differently when the debt is secured by the place your family lives. This is why income stability is a hard requirement, not a nice-to-have.
Before you sign: three alternatives
0% balance transfer card
Best for balances you can clear in 12 to 21 months. A 3 to 5% fee buys you a window where every dollar hits principal, and your house stays out of it entirely.
Unsecured personal loan
Fixed rate, fixed term, no collateral. Rates are higher than a HELOC (often 10 to 15% for good credit) but the worst case is credit damage, not foreclosure. A reasonable middle path.
The no-product plan
Freeze the cards, pick avalanche or snowball, attack with a fixed monthly payment. On paper it costs more interest than a HELOC. In practice it has the highest completion rate, because there is no new credit line to misuse.

The verdict
Use a HELOC if: the spending stopped months ago, your income is solid, the rate drop is steep, and you commit to a fixed payoff schedule in writing before you sign.
Skip it if: the balances are still creeping up, your income is uncertain, or any part of you sees the freed-up cards as breathing room. The 22% is expensive. Your house is more expensive.
One more thing: the people who succeed with a HELOC treat it as step five of a payoff plan, not step one. The plan (frozen spending, one payoff order, a fixed payment) is what gets you debt-free. The HELOC just makes the ride cheaper.

Frequently asked questions
Is it a good idea to use a HELOC to pay off credit card debt?
Only if all four conditions hold: your card spending is already fixed (the balances stopped growing months ago), your income is stable, the rate gap is large (say 22% down to 9%), and you have a firm payoff schedule instead of interest-only minimums. If any one of those is missing, you are moving unsecured debt onto your house without fixing the thing that created it.
How much does a HELOC actually save compared to credit cards?
The gap is real. On $20,000 at a $600 monthly payment, a 22% card costs roughly $11,000 in interest over about 4 years 4 months, while a 9% HELOC costs about $3,100 over roughly 3 years 3 months. That is around $8,000 saved. The savings only materialize if you keep the same payment and never re-run the cards.
What is the biggest risk of using a HELOC to pay off credit cards?
The debt becomes secured by your home. Credit card debt is unsecured: miss payments and you face fees and credit damage, but nobody takes your house. Move that debt to a HELOC and a long stretch of missed payments can end in foreclosure. You are trading a lower rate for a much higher worst-case outcome.
What is the re-spend trap with a HELOC?
After the HELOC pays off your cards, the cards show zero balances and feel usable again. Studies of consolidation borrowers consistently find a large share rebuild their card balances within a year or two, ending up with the original debt amount on cards plus the HELOC payment, and their home on the line. If the spending is not fixed first, consolidation reliably makes things worse.
Why are interest-only HELOC payments dangerous?
Most HELOCs have a draw period, often 10 years, where the required payment covers only interest. Pay just the minimum and after a decade you still owe every dollar of principal, and then the repayment period starts with much larger required payments. If you use a HELOC, set your own amortizing payment from day one so the balance actually falls.
Are HELOC rates fixed or variable?
Usually variable, tied to the prime rate. The 9% you sign at can drift upward with the rate environment, which slowly shrinks your savings versus the fixed math you ran at signing. Some lenders offer fixed-rate conversion on portions of the balance; if you go this route, that option is worth prioritizing.
What are the alternatives to a HELOC for credit card debt?
Three main ones. A 0% balance transfer card is often best for balances you can clear in 12 to 21 months. An unsecured personal loan consolidates at a fixed rate without touching your house. And the no-product option: freeze spending, pick an avalanche or snowball order, and attack with a fixed monthly payment. Slower on paper, but nothing is at risk except your patience.
