A HELOC is a line of credit secured by your home's value

HELOC stands for Home Equity Line of Credit. It is a borrowing tool that lets you access money based on how much your home is worth minus what you still owe on your mortgage. Unlike a home equity loan, which gives you one lump sum upfront, a HELOC works like a credit card — you can borrow, repay, and borrow again during a set period called the draw period.

The lender uses your home as collateral, which means if you stop making payments, the lender can foreclose. Because your home backs the loan, HELOCs typically carry lower interest rates than credit cards or personal loans. The rate is usually variable, meaning it changes over time based on market conditions.

Key Takeaways

  • A HELOC lets you borrow against your home's equity — the difference between what your home is worth and what you owe on your mortgage.
  • You can draw money as needed during the draw period (usually 5 to 10 years), then enter a repayment period where you pay back what you borrowed.
  • Interest rates on HELOCs are typically variable and lower than credit cards, but your rate can rise if market rates increase.
  • Your home secures the HELOC, so missing payments can result in foreclosure.

How the draw period and repayment period work

A HELOC has two phases. During the draw period, you can withdraw money up to your credit limit whenever you need it. You typically pay only interest during this time, not principal. Draw periods usually last 5 to 10 years, though the exact length depends on your lender and the terms you agree to.

After the draw period ends, you enter the repayment period, which usually lasts 10 to 20 years. During repayment, you can no longer withdraw new money. Instead, you must pay back the full balance — both principal and interest — on a set schedule. Your monthly payment will be much higher during repayment than it was during the draw period, because you are now paying down the actual debt.

Some HELOCs convert to fixed-rate loans at the end of the draw period, while others keep a variable rate. Read your agreement carefully to understand what happens when your draw period ends.

What determines how much you can borrow

The amount you can borrow depends on your home's current value, what you still owe on your mortgage, and your credit history. Most lenders let you borrow up to 80 or 85 percent of your home's total value, minus your mortgage balance. For example, if your home is worth $300,000 and you owe $150,000 on your mortgage, your equity is $150,000. A lender might let you borrow up to $90,000 (60 percent of the home's value).

Lenders also look at your credit score, income, and debt-to-income ratio. A higher credit score and stable income make you more likely to get approved and receive a lower interest rate. If your home's value drops significantly, your lender may reduce your available credit or freeze your account.

HELOC versus a home equity loan

Both tools use your home as collateral, but they work differently. A home equity loan gives you one large payment upfront and requires fixed monthly payments over a set term. A HELOC is more flexible — you draw money as you need it and pay interest only on what you use.

Home equity loans have fixed interest rates, so your payment never changes. HELOCs have variable rates, which means your payment can increase if interest rates rise. If you need a specific amount for a single purpose (like a renovation), a home equity loan may be simpler. If you want ongoing access to money for multiple needs over time, a HELOC offers more flexibility.

Interest rates and how they change

HELOC interest rates are almost always variable, tied to a benchmark rate like the prime rate. When the benchmark rises, your rate rises. When it falls, your rate falls. This means your monthly payment can change, sometimes significantly. During periods of rising rates, borrowers with HELOCs often see their payments jump.

Your actual rate depends on the benchmark plus a margin set by your lender. A lender might charge prime rate plus 1 percent, for example. Some HELOCs include a rate cap — a maximum rate you will never exceed — but not all do. Before opening a HELOC, ask your lender what the current rate is, what the margin is, whether there is a rate cap, and what the highest possible rate could be.

Risks and costs to understand

The biggest risk is foreclosure. If you cannot pay back what you borrowed, the lender can take your home. This makes a HELOC riskier than unsecured debt like credit cards, even though the interest rate is lower.

Variable rates create payment uncertainty. If rates spike, your monthly payment could double or triple, straining your budget. Some borrowers borrow heavily during the draw period, then face unaffordable payments when the repayment period begins and rates are higher.

HELOCs also come with fees: application fees, appraisal fees, annual fees, and sometimes early closure fees if you pay off the line before a certain date. Ask your lender for a full list of costs before you commit.

When people typically use a HELOC

Homeowners use HELOCs for major expenses: home renovations, medical bills, education costs, or debt consolidation. Because the interest rate is lower than credit cards, consolidating high-interest debt into a HELOC can reduce what you pay overall — but only if you do not borrow more during the draw period.

Some people use a HELOC as emergency backup, opening one and leaving it unused until they need it. This gives them access to money without taking on debt upfront. Others use it to fund a business or investment. The flexibility of drawing money as needed makes it useful for expenses that happen over time rather than all at once.

Frequently Asked Questions

Can I lose my home if I do not pay back a HELOC?

Yes. A HELOC is secured by your home, so if you stop making payments, the lender can foreclose and take the house. This is the main risk of a HELOC compared to other types of borrowing.

What happens if my home's value drops?

Your lender may freeze your account or reduce your credit limit. If you owe more than your home is worth, you may not be able to borrow more. Some lenders also require you to pay back part of what you borrowed.

Can my interest rate go down as well as up?

Yes, because HELOC rates are variable. If the benchmark rate falls, your rate falls too. However, most HELOCs have a floor — a minimum rate you will never go below — so your rate will not drop indefinitely.

What if I cannot afford my payment when the repayment period starts?

Contact your lender immediately. Some lenders offer options like extending the repayment period or converting to a fixed rate. Waiting until you miss a payment makes your options much smaller and damages your credit.

Do I have to use the full credit limit?

No. You only pay interest on the money you actually borrow, not on your full credit limit. Many people open a HELOC and use only part of it, keeping the rest available for emergencies.
