A HELOC and a credit card are not the same product, even though both let you borrow money

A HELOC (home equity line of credit) is a loan secured by your home's value. A credit card is unsecured debt. That difference changes how much you can borrow, what interest rate you pay, how long you have to repay, and what happens if you stop paying. A HELOC typically offers lower interest rates and larger borrowing limits because the lender can seize your home if you default. A credit card charges higher rates but does not put your house at risk, and you can carry a balance month to month without a fixed repayment schedule.

People sometimes confuse the two because both function like a line of credit — you borrow what you need, up to a limit, and pay interest on the balance. But the terms, costs, and consequences are fundamentally different. Understanding which tool fits your situation requires knowing how each one works and what you stand to lose.

Key Takeaways

  • A HELOC is secured by your home and typically carries a lower interest rate than a credit card, but defaulting puts your house at risk of foreclosure.
  • Credit cards are unsecured, charge higher interest rates, and do not require a fixed repayment schedule, but you cannot borrow as much as you can with a HELOC.
  • HELOCs have a draw period (usually 5 to 10 years) when you can borrow, followed by a repayment period when you can only pay down the balance.
  • Credit cards let you borrow continuously as you pay down your balance, with no separate repayment phase.
  • A HELOC makes sense for large, planned expenses like home renovation or debt consolidation; a credit card works better for ongoing spending or emergencies when you cannot risk your home.

How a HELOC works and what it costs

A HELOC lets you borrow against the equity you have built in your home. If your home is worth $300,000 and you owe $200,000 on your mortgage, you have $100,000 in equity. Most lenders will let you borrow 80 to 90 percent of that equity, so in this example you might get a HELOC for $70,000 to $80,000. The lender files a lien against your home, meaning they have a legal claim to it if you do not pay.

A HELOC has two phases. During the draw period — usually 5 to 10 years — you can borrow and repay as often as you want, like a credit card. You pay interest only on what you actually borrow. After the draw period ends, the repayment period begins, typically lasting 10 to 20 years. During repayment, you cannot borrow anymore; you can only pay down the balance. Many HELOCs convert to fixed-rate loans at this point, and your monthly payment jumps because you now have a set schedule.

Interest rates on HELOCs are usually variable, tied to the prime rate. When the Federal Reserve raises rates, your HELOC rate rises too, and so does your monthly payment. Some lenders offer fixed-rate HELOCs or let you lock in part of your balance at a fixed rate, but these typically cost more upfront. Because the loan is secured by your home, rates are usually 2 to 5 percentage points lower than credit card rates.

How a credit card works and what it costs

A credit card is unsecured debt. The card issuer has no claim on your home or other assets if you do not pay. Because of that risk, card issuers charge higher interest rates — typically 15 to 25 percent, depending on your credit score and the card. You can borrow up to your credit limit, which is usually much smaller than a HELOC limit. A typical credit card limit might be $5,000 to $15,000; a HELOC might be $50,000 or more.

You can carry a balance on a credit card indefinitely, paying interest each month, with no separate repayment phase. You can also pay off the full balance each month and pay no interest at all. There is no draw period or repayment period — the terms stay the same as long as the account is open. If you stop paying, the card issuer cannot take your home, but they can sue you, report you to credit bureaus, and eventually sell your debt to a collection agency.

Credit card interest rates are usually fixed, meaning they do not change when the Federal Reserve moves rates (though issuers can raise your rate if you miss a payment or if your introductory rate expires). Some cards offer a 0 percent introductory period on purchases or balance transfers, lasting 6 to 21 months depending on the card. After that period ends, the regular rate kicks in.

When a HELOC makes financial sense

A HELOC is most useful when you need to borrow a large amount for a specific purpose and can afford the payments. Common uses include home renovation, paying for education, consolidating high-interest debt, or covering a major medical expense. Because HELOC rates are lower than credit card rates, you save money on interest if you borrow $20,000 or more.

A HELOC also makes sense if you have a predictable need to borrow over time. For example, if you are renovating your home in phases over two years, you can draw money as each phase begins and pay interest only on what you have actually used. You do not have to borrow the full amount upfront.

The trade-off is risk. If you cannot make your HELOC payments, the lender can foreclose on your home. This is a real consequence, not a theoretical one. You are also exposed to rate increases if your HELOC has a variable rate. If rates rise sharply during the draw period, your interest costs climb. And when the repayment period begins, your monthly payment can jump significantly if the lender converts the balance to a fixed-rate loan with a shorter repayment window.

When a credit card makes more sense than a HELOC

A credit card is the safer choice if you cannot afford to risk your home. If you miss payments on a credit card, your credit score drops and collectors may pursue you, but you keep your house. This matters if your income is unstable or if you are uncertain whether you can repay.

A credit card also works better for smaller purchases, ongoing spending, or emergencies. If you need $2,000 for a car repair, a credit card is faster and simpler than explore for a HELOC. You can use it when ready, and if you pay off the balance within the grace period (usually 21 to 25 days), you pay no interest. A HELOC process takes weeks and involves an appraisal and credit check.

Credit cards are also better if you want flexibility. You can pay off a credit card balance in full one month and carry a balance the next month with no penalty. A HELOC locks you into a draw period and repayment period structure. And if you are worried about rising interest rates, a fixed-rate credit card protects you; a variable-rate HELOC does not.

The real cost difference between the two

The interest rate difference is substantial for large balances. Suppose you borrow $15,000 and pay it back over three years. At a 7 percent HELOC rate, you pay about $1,600 in interest. At a 20 percent credit card rate, you pay about $4,900 in interest — three times as much. For a $5,000 balance over the same period, the HELOC costs about $530 and the credit card costs about $1,600.

But this advantage only matters if you actually borrow a large amount. If you need $1,000 and pay it back in two months, the interest cost on either product is minimal. The real cost of a HELOC is the process fee (usually $0 to $500), the appraisal fee (usually $300 to $500), and the risk that you will lose your home if you cannot pay. For small or short-term borrowing, a credit card is cheaper and safer.

What happens when a HELOC draw period ends

When your HELOC draw period ends, the terms change. You can no longer borrow new money. Your lender converts the outstanding balance to a repayment loan, usually with a fixed rate and a set monthly payment. This payment is often much higher than what you were paying during the draw period, because you now have to repay the entire balance within a fixed timeframe instead of just paying interest.

Some lenders let you renew your HELOC for another draw period, but this is not may provide. If your home value has dropped or your credit has deteriorated, the lender may refuse to renew or may offer a much smaller line. If you cannot renew and cannot afford the new repayment payment, you may have to refinance into a traditional loan or sell your home.

This is why a HELOC is riskier than it appears during the draw period. The low payments you enjoy for 5 to 10 years can jump dramatically when repayment begins. If you are counting on refinancing or selling your home to avoid that jump, you are betting on future conditions you cannot control.

Frequently Asked Questions

Can I use a HELOC like a credit card?

During the draw period, yes — you can borrow and repay repeatedly, and you pay interest only on what you use. But a HELOC is not a credit card. You cannot use it at stores or online; you typically access the money through checks, transfers, or a debit card the lender provides. And once the repayment period begins, you cannot borrow anymore.

What happens if I cannot pay my HELOC?

The lender can foreclose on your home. This is the biggest risk of a HELOC. If you miss payments, the lender will try to collect, report you to credit bureaus, and eventually file a foreclosure action. You could lose your home even if you have paid off your mortgage.

Is a HELOC a good way to pay off credit card debt?

It can be if you borrow enough to pay off all your cards at once and then do not run up new balances. You save money on interest because HELOC rates are lower. But if you pay off your credit cards with a HELOC and then run up the cards again, you end up with both debts — the HELOC and the new credit card balances. This is a common trap.

Can I get a HELOC if I have bad credit?

It is harder than getting a credit card, but possible. Most lenders require a credit score of at least 620, though some want 700 or higher. Because the loan is secured by your home, lenders care more about your home equity and income than they do about your credit score. But a lower score usually means a higher interest rate.

What is the difference between a HELOC and a home equity loan?

A home equity loan is a one-time loan for a fixed amount, with a fixed rate and a set repayment schedule. A HELOC is a line of credit you can draw from repeatedly during the draw period. A home equity loan is simpler if you need a specific amount once; a HELOC is more flexible if you need to borrow over time.
