Home Equity Loan to Pay Off Credit Card Debt: The Real Math
If you own a home and you're carrying credit card balances at 22% to 24%, somebody has probably told you to "just pull some equity out and wipe the cards." It's not crazy advice. It's also not free. You're trading an unsecured debt for one that's attached to the roof over your head.
Brian walks through it on video.
So let's do it the way I like to do everything on this site: actual numbers, no hype, no shame. By the end you'll know whether this move saves you money, how much, and what has to be true for it to be worth the risk.
What a home equity loan is, in plain English
You have to own a home to get one. The reason it's called a home equity loan is that your house is the asset backing it — the same way your car backs a car loan. Miss enough car payments and they take the car. Miss enough payments on a loan secured by your home and they can take the house.
Equity is simply what the house is worth minus what you owe on it. Owe $300,000, house appraises at $500,000, you have $200,000 in equity. That money is locked up — you can't spend it unless you sell. A lender will do some kind of assessment and may then offer you a second loan against part of it. The mortgage stays first in line; the equity loan sits second. Borrow $100,000 against that equity and you now owe $400,000 on the house.
Why the interest rate is so much lower
This is the part worth understanding, because it explains every rate you've ever been quoted.
Unsecured debt has no asset behind it. A credit card is unsecured — if you stop paying, there's nothing specific for them to repossess. Lenders price that risk into the rate, which is why new cards commonly land around 24% when you carry a balance.
Secured debt is backed by something they can take. A car loan is secured by the car. A home equity loan is secured by your home. Because they have recourse, you get a better rate.
Rough ranges to keep in your head:
| Debt type | Secured? | Typical range |
|---|---|---|
| Credit card | No | Around 22%–24% |
| Personal loan | Often no | Depends heavily on credit score; can be ~18% |
| Car loan | Yes | Roughly 6%–12%, sometimes lower through the manufacturer |
| Home equity loan | Yes (your house) | Well below card rates with decent equity |
Notice the personal loan line. Going from a 22% card to an 18% personal loan is not much of a win. That's why people with equity look at the home option — the spread is actually large enough to matter.
The worked example: $20,000 at 24% vs 10%
Round numbers so you can follow along. You have $20,000 spread across three cards at 24% APR, and you can put $600 a month toward them.
Option 1: keep the cards, pay $600 a month
At 24% on $20,000, your first month alone costs about $400 in interest. Only about $200 of that $600 touches the balance. Keep paying $600 and you're looking at roughly 56 months — about four years and eight months — and somewhere around $13,000 in interest paid.
Option 2: home equity loan at 10%, but take the low payment
You borrow $20,000 at 10% on a 10-year term. The required payment drops to about $264 a month. That feels amazing. It is also a trap: over 120 months you'd pay roughly $11,700 in interest. You cut the rate by more than half and barely saved anything, because you stretched the time out.
Option 3: home equity loan at 10%, keep paying $600
Same loan, but you ignore the low required payment and keep throwing the $600 you were already sending to the cards. Now you're done in roughly 39 months — a little over three years — with about $3,500 in interest.
| Plan | Payment | Time | Interest |
|---|---|---|---|
| Cards at 24% | $600 | ~56 months | ~$13,000 |
| Home loan at 10%, minimum | $264 | 120 months | ~$11,700 |
| Home loan at 10%, $600 | $600 | ~39 months | ~$3,500 |
Same debt. Same payment in rows one and three. About $9,500 difference and more than a year of your life. That's the entire case for this move — and it only exists if you refuse to take the lower payment.
Plug your own balances and rates into the Debt Consolidation Calculator before you do anything. Your numbers will be different from mine, and the decision should come from your numbers.
The two ways this goes wrong
1. You run the cards back up
This is the big one. You clear three cards, see a pile of available credit, and six months later you've got balances again — plus a loan against your house. You just doubled your problem. The goal is not to move debt around. The goal is to stop carrying card balances at all so you pay zero card interest.
If spending is the actual issue, fix that first. Start with cutting expenses temporarily and build a real payment number using the Budget Calculator.
2. You take the small payment and relax
Row two of that table. A long term with a low payment feels like relief, and it's the default the lender hands you. Decide up front that your payment stays at whatever you were sending the cards, and set up the transfer so it happens automatically.
What changes on your credit report
Credit cards are revolving credit. A home equity loan is a term loan: fixed amount, fixed payment, fixed number of months. Ten years is 120 payments and then it's over. Some people find that structure easier to live with because there's a real end date instead of a balance that drifts up and down forever. You can pin that date down using the debt-free date walkthrough.
Who this actually fits
Honestly? Often the people who get steered here are people whose credit took a hit from the card balances in the first place. When your score isn't great, unsecured borrowing is expensive or simply unavailable — a personal loan at 18% doesn't solve anything. If you have real equity, a secured loan may be the only option with a rate low enough to matter.
Before you commit, check three things:
- Your equity. Home value minus mortgage balance. Expect an appraisal or assessment.
- Your ability to pay. Run your Debt-to-Income Ratio Calculator number. Adding a secured payment you can't reliably make is the worst version of this.
- Your alternatives. A 0% balance transfer, a car refinance, or just attacking the highest rate first might get you there without touching the house. Compare with the Debt Avalanche Calculator and read up on using an auto refinance to pay off credit card debt.
A simple checklist
- List every card: balance and APR.
- Figure your equity and get a real quote — rate, term, and fees, not a ballpark.
- Compare total interest both ways. If the savings are small, skip it.
- Borrow only enough to clear the cards. Not a dollar more for a kitchen or a boat.
- Keep the old payment amount. Automate it.
- Use the cards for nothing you can't pay off in full that month.
- Pay the home equity loan off as fast as you can — it's secured by your house.
Bottom line
A home equity loan doesn't reduce what you owe. It changes the price of what you owe. Moving $20,000 from 24% to 10% while keeping the same monthly payment can save thousands in interest and over a year of payments — and that's a genuinely good trade for a lot of people.
But it converts debt that could never cost you your home into debt that can. So the test is simple: does this help me get out of debt faster and save real money, and can I make that payment every single month no matter what? If both answers are yes, it's worth considering. If either one is shaky, keep looking at the other free calculators and find a path that doesn't put the house on the table.
This is general education, not financial advice. Run your own numbers before you sign anything.
