How HELOC payments work

A HELOC payment is money you send to your lender each month, usually starting after you stop borrowing. The payment covers interest on what you've borrowed, and may also cover principal (the amount you actually owe). The exact payment amount depends on how much you've drawn, the interest rate at that moment, and whether you're in the draw period (when you can still borrow) or the repayment period (when you cannot).

Most HELOCs work in two phases. During the draw period — typically 5 to 10 years — you can borrow and reborrow as you need it, and you usually pay interest only, which keeps monthly payments low. Once the draw period ends, the repayment period begins, and your payment jumps because you now owe both interest and principal, usually over 10 to 20 years. Understanding which phase you're in matters, because your payment can double or triple when you switch.

Key Takeaways

  • During the draw period, you typically pay interest only on what you've borrowed, which is why payments stay low; once repayment starts, you pay both interest and principal, and your payment rises sharply.
  • Your monthly payment changes if the interest rate changes, because most HELOCs have variable rates that move with the market, unlike a fixed-rate mortgage.
  • You can choose to pay more than the minimum at any time, and paying principal early reduces the total interest you'll owe over the life of the loan.
  • If you stop borrowing but don't make payments, the lender can freeze your account and demand full repayment, or begin foreclosure proceedings against your home.

Interest-only payments during the draw period

During the draw period, your monthly payment usually covers interest only. This means if you've borrowed $25,000 at 8% annual interest, your monthly payment is roughly $167 (that's $25,000 × 0.08 ÷ 12). You're not paying down the $25,000 itself — you're just paying the cost of borrowing it.

This structure keeps early payments low, which is why people use HELOCs for short-term needs like home repairs or debt consolidation. But it also means the full $25,000 is still owed when the draw period ends. If you've been paying interest-only for 7 years and then the repayment period begins, your payment suddenly includes principal repayment, and it can jump 50% or more.

Some lenders let you pay principal during the draw period even though it's not required. Doing so reduces the balance and the interest you'll owe later, but it's optional. Most people in the draw period pay only the interest-only minimum.

Principal and interest payments during repayment

When the repayment period begins, your payment changes to cover both principal and interest. The lender calculates a new monthly payment that will pay off the entire remaining balance over the repayment term — often 10, 15, or 20 years, depending on your loan agreement.

If you owed $25,000 at the start of repayment and the rate is 8%, a 15-year repayment term means your new monthly payment is roughly $186. That's higher than the $167 interest-only payment, but it actually pays down the debt. After 15 years of these payments, the HELOC is closed and you owe nothing.

The exact payment depends on three things: the remaining balance, the current interest rate, and the length of the repayment term. If rates have risen since you opened the HELOC, your payment will be higher. If rates have fallen, it will be lower. This is why variable-rate HELOCs feel unpredictable — you don't know what your payment will be until the repayment period starts and the lender calculates it.

Variable interest rates and payment changes

Most HELOCs have variable interest rates, meaning the rate changes when the market changes. Your lender ties your rate to a public index — usually the prime rate — and adds a margin on top. If the prime rate goes up 1%, your rate goes up 1%, and your monthly payment goes up too.

During the draw period, a rate increase might raise your interest-only payment from $167 to $180. During repayment, the same rate increase could raise your payment from $186 to $210, because you're paying both interest and principal on a higher rate. Over a 15-year repayment period, a 2% rate increase can add hundreds of dollars to your total cost.

Some HELOCs have a rate cap — a maximum rate your lender can charge — but not all do. Read your loan documents to see whether your rate can rise indefinitely or whether there's a ceiling. If rates are historically low when you open the HELOC, the risk of future increases is real.

Minimum payments versus paying more

Your lender sets a minimum monthly payment, but you can pay more at any time without penalty. Paying extra principal reduces the balance faster and cuts the total interest you'll owe. If your minimum payment is $186 and you send $250, the extra $64 goes straight to principal.

This matters most during the draw period, when you're paying interest-only. If you pay $300 a month instead of the required $167, you're building equity in the HELOC and reducing what you'll owe when repayment begins. By the time the repayment period starts, your balance might be $15,000 instead of $25,000, and your repayment payment will be lower.

During repayment, extra payments also help, but the math is different. Your regular payment already includes principal, so extra money accelerates payoff and saves interest, but the benefit is smaller than during the draw period. Still, paying $250 instead of $186 means you'll finish paying off the HELOC years earlier.

What happens if you miss a payment

Missing a HELOC payment has serious consequences because your home is collateral. If you miss one payment, your lender typically charges a late fee and reports the miss to credit bureaus, which damages your credit score. If you miss several payments in a row, the lender can freeze your account, preventing you from borrowing more, and can demand that you pay the entire remaining balance immediately.

If you don't pay after the lender demands it, they can begin foreclosure — a legal process to take your home and sell it to recover what you owe. This is different from a credit card default, where the worst outcome is a lawsuit and wage garnishment. With a HELOC, the worst outcome is losing your house.

If you're struggling to make payments, contact your lender before you miss one. Some lenders will work with you to lower your payment temporarily, extend your repayment term, or convert your HELOC to a fixed-rate loan. These options are easier to arrange before you default than after.

Paying off a HELOC early

You can pay off a HELOC in full at any time. Some lenders charge a prepayment penalty if you pay off during the draw period, but many don't — check your loan documents. If there's no penalty, paying off early saves you all the interest you would have paid over the remaining term.

If you're in the draw period and you pay off the full balance, the account closes and you can no longer borrow from it. Some people close the account intentionally to avoid temptation; others keep it open (by not borrowing) in case they need emergency funds later. Keeping it open costs nothing if you're not using it.

If you're in the repayment period and you pay off early, you save interest on the remaining balance. If you have 10 years left on a 15-year repayment term and you pay the full balance, you avoid 5 years of interest payments. The exact savings depends on your rate and remaining balance — your lender can calculate it if you ask.

Frequently Asked Questions

What's the difference between a HELOC payment and a home equity loan payment?

A home equity loan has a fixed payment from day one, because it's a lump sum with a fixed rate and term. A HELOC has a low interest-only payment during the draw period, then a higher payment during repayment. Home equity loans are predictable; HELOCs are flexible but riskier because the payment can jump.

Can my HELOC payment go down if interest rates fall?

Yes, if your HELOC has a variable rate and rates fall, your payment goes down. During the draw period, a lower rate means a lower interest-only payment. During repayment, a lower rate means your new payment (recalculated by the lender) is lower. But the opposite is also true — rates can rise and your payment can increase.

What happens to my HELOC payment if I stop borrowing?

If you stop borrowing but keep the account open, your payment stays the same as long as you're in the draw period — you pay interest on what you've already borrowed. Once the draw period ends, your payment changes to include principal repayment. Stopping borrowing doesn't change the payment schedule; only the end of the draw period does.

Do I have to make a payment during the draw period?

Yes. Even during the draw period, you must make the interest-only payment each month. If you don't borrow anything, your payment is zero, but as soon as you draw money, you owe interest on it. Missing payments during the draw period has the same consequences as missing them during repayment — late fees, credit damage, and eventually foreclosure.

Can I convert my HELOC to a fixed-rate loan?

Some lenders allow you to convert part or all of your HELOC balance to a fixed-rate home equity loan, which locks in your rate and payment for the rest of the term. This is useful if rates are rising and you want to protect yourself from future increases. Ask your lender whether conversion is an option and what fees apply.
