How HELOC Repayment Works

A HELOC repayment happens in two phases: a draw period when you can borrow money, and a repayment period when you pay it back. During the draw period—usually 5 to 10 years—you can withdraw funds as needed and make interest-only payments on what you've borrowed. Once the draw period ends, the repayment period begins, typically lasting 10 to 20 years, and you must pay back both principal and interest on the full balance.

The mechanics are straightforward: you owe money on whatever you've drawn, interest accrues on that balance, and your lender sends you a monthly bill. You can pay just the interest during the draw phase, or you can pay down principal early without penalty. Once repayment begins, you no longer draw new money—you're only paying down what you already borrowed.

Key Takeaways

  • During the draw period, you pay interest only on money you've actually withdrawn, and you can borrow more whenever you need it.
  • When the draw period ends, your monthly payment jumps because you now owe both principal and interest, and the balance is locked.
  • Most HELOCs have variable interest rates, so your payment can increase if rates rise, especially after the draw period ends.
  • You can pay down your HELOC faster than required, and most lenders do not charge prepayment penalties for doing so.
  • If you cannot afford the payment when repayment begins, contact your lender when ready—some offer options to extend or restructure the loan.

The Draw Period: Interest-Only Payments

During the draw period, you only pay interest on the money you've actually used. If you have a $100,000 HELOC but have only drawn $30,000, you pay interest on $30,000, not the full $100,000. Your monthly payment is calculated by multiplying your current balance by the interest rate and dividing by 12.

This is where a HELOC differs from a traditional loan: you control when and how much you borrow. You can draw $5,000 one month, $15,000 six months later, and nothing for a year. Each withdrawal adds to your balance, and interest starts accruing on it when ready. Most lenders let you draw money by writing a check, using a debit card, or transferring funds online.

During this phase, your payment is predictable only if your interest rate is fixed. Many HELOCs have variable rates tied to the prime rate, so if the Federal Reserve raises rates, your payment goes up even though you haven't borrowed more money. Check your loan documents to see whether your rate is fixed or variable.

When the Draw Period Ends: The Payment Shock

The draw period ends on a specific date set when you opened the HELOC. On that date, you stop being able to withdraw new money, and your monthly payment changes dramatically. Instead of paying interest only on what you've drawn, you now pay principal and interest on the full balance over the remaining loan term.

This is called payment shock, and it catches many borrowers off guard. If you've been paying $300 a month in interest-only payments, your new payment might jump to $600 or $800 once repayment begins, depending on your balance and the remaining term. The lender must notify you before this happens—usually 60 to 120 days in advance—but the increase is real and unavoidable unless you refinance or pay off the balance.

The exact new payment depends on three things: how much you still owe, what your interest rate is at that moment, and how many years you have left to repay. A $50,000 balance at 8% interest over 15 years costs roughly $477 per month. The same balance at 10% costs roughly $529 per month. If your rate is variable, it may have changed since you opened the account.

Variable Rates and Payment Changes

Most HELOCs have variable interest rates, which means your rate—and your payment—can change over time. The rate is usually tied to the prime rate published by the Federal Reserve, plus a margin set by your lender. When the prime rate moves, your rate moves with it, typically within 30 to 60 days.

During the draw period, a rate increase stings but is manageable because you're paying interest only. During repayment, a rate increase hits harder because you're paying both principal and interest. If rates rise 2%, your monthly payment on a $50,000 balance could increase by $80 to $100 per month. Over 15 years, that adds up.

Some HELOCs offer a fixed-rate option, either for the entire loan or for a portion of it. If your lender offers this, you can lock in your rate before the draw period ends, protecting yourself from future increases. Ask your lender whether this option is available and what it costs.

Making Payments: Methods and Timing

Your lender sends you a bill each month showing your current balance, the interest charged, any principal payment, and the total due. You can pay by check, automatic bank transfer, credit card (though this usually costs a fee), or through your lender's online portal. Most lenders require payment by the 15th or 20th of the month, though the exact date is in your loan agreement.

Payments are applied first to interest, then to principal. This means early in the repayment period, most of your payment goes toward interest and very little toward reducing the balance. As time passes and the balance shrinks, more of each payment goes to principal. This is normal and expected.

You can pay more than the minimum at any time without penalty. Many borrowers pay extra during the draw period to reduce the balance before repayment begins, which lowers the payment shock. Others make extra payments during repayment to finish the loan faster and pay less interest overall.

What Happens If You Cannot Afford the Payment

If your payment jumps at the end of the draw period and you cannot afford it, contact your lender before you miss a payment. Some lenders offer options: extending the repayment period (which lowers the payment but costs more interest), converting part of the balance to a fixed-rate loan, or temporarily reducing the payment while you adjust your budget.

Missing payments damages your credit score and can lead to default. Your lender can freeze your account, preventing new draws, and can eventually foreclose on your home if you fall far enough behind. The key is to communicate early—lenders are often more willing to work with you before you default than after.

If refinancing is an option, you might roll the HELOC balance into a new loan with a lower rate or longer term. This requires a new process and a credit check, but it can reduce your payment significantly if rates have fallen or if you have more equity than when you opened the HELOC.

Paying Off Your HELOC Early

You can pay off your HELOC balance in full at any time. There is no prepayment penalty on most HELOCs, so you will not be charged extra for paying it off early. This is different from some mortgages or personal loans, which may charge a fee if you pay off the loan before a certain date.

Paying off early saves you interest. If you have 10 years left on a $50,000 balance at 8% interest, you would pay roughly $28,600 in total interest over the life of the loan. If you pay it off in 5 years instead, you pay roughly $12,000 in interest—a savings of over $16,000. The faster you pay, the more you save.

Some borrowers use a HELOC as a short-term tool: they borrow for a specific purpose, like a home renovation or debt consolidation, and then pay it off within a few years. Others keep the HELOC open as a backup line of credit even after paying the balance to zero, in case they need to borrow again later.

Frequently Asked Questions

What happens if I only pay the interest during the draw period?

You will owe the full balance when the draw period ends. Your lender will then require you to pay principal and interest over the repayment period. If you cannot afford the new payment, you may need to refinance or negotiate with your lender before you fall behind.

Can my interest rate change during repayment?

Yes, if you have a variable-rate HELOC. Your rate is tied to the prime rate, which changes when the Federal Reserve adjusts rates. A fixed-rate HELOC or a fixed-rate portion of your HELOC will not change. Check your loan documents to see which type you have.

Do I have to make a payment every month?

Yes. Your loan agreement requires a monthly payment. During the draw period, this is usually interest only. During repayment, it includes both principal and interest. Missing payments damages your credit and can lead to default or foreclosure.

What if I want to borrow more money after the draw period ends?

You cannot. Once the draw period ends, the credit line closes and you can no longer withdraw new funds. You can only pay down the existing balance. If you need more money, you would need to open a new HELOC or use a different type of loan.

Is there a penalty for paying off my HELOC early?

No. Most HELOCs do not charge prepayment penalties, so you can pay off the balance whenever you want without extra fees. Paying early saves you interest and gets you out of debt faster.
