Quick insights

As you think about tapping into the value of your home to fund other expenses, you might be considering an interest-only HELOC. These loans are designed to provide homeowners with much-needed flexibility (along with a much lower upfront cost) compared to other traditional loans.

With a home equity line of credit, you’re borrowing against the equity in your home. You can normally borrow up to 80% of the home’s value, depending on your equity and the lender. (Not sure what your home value is? Our home value calculator may be able to help.)

An interest-only HELOC can be helpful if you’re managing higher expenses or want access to cash without committing to hefty monthly payments right out of the gate.

As appealing as it might sound, and despite the benefits, an interest-only HELOC comes with drawbacks, warranting careful planning.

What is an interest-only HELOC?

An interest-only home equity line of credit (interest-only HELOC) allows you to borrow money in chunks by tapping into your home’s equity as needed, rather than taking out a lump sum upfront. Essentially, you’re turning your home’s equity into a flexible borrowing account, from which the lender has provided you a credit limit.

The “interest-only” part means that, for a set period, you pay only the interest on the amount you’ve borrowed, with no principal included. This results in much lower payments at first, but it also means that the amount you owe (the principal) doesn’t decrease during this time.

For example, if your lender approves a $75,000 HELOC, you might pay interest only on whatever portion you decide to borrow. If you borrow $10,000 for home renovations, your payments during the first phase would only cover interest on that $10,000 unless you choose to pay back more.

The flexibility of this arrangement makes it popular for short-term financial needs, like covering college tuition, making home upgrades or managing unexpected expenses. However, because you’re delaying repayment of the principal, it’s important to plan ahead to avoid payment challenges later.

What is the interest-only HELOC repayment period?

Interest-only HELOCs have two distinct phases: the draw period and the repayment period.

Draw period

The draw period, which typically lasts 3 to 10 years, is when you can access your line of credit as needed. During this phase, you’re only required to make interest payments, which can free up cash flow for other expenses.

For example, let’s say you have a $50,000 HELOC with a 6% interest rate. If you borrow the full $50,000, an interest-only payment would amount to about $250 per month during the draw period. (Though remember that these amounts vary depending on lender terms and rate changes.)

The draw phase offers freedom but requires a heavy dose of discipline. It’s easy to borrow more than you can comfortably repay when you’re making minimal payments, so you may want to keep yourself on a strict budget to avoid overextending yourself.

Repayment period

Once the draw period ends, the repayment period begins. This lasts 10–20 years, depending on the loan terms. In this stage, your payments include both principal and interest, resulting in higher monthly payments.

Returning to the earlier example, your monthly obligation in the repayment period would be approximately $555 for a 10-year loan (more than double the amount during the draw period).

The number is significantly higher because it includes both the interest and the principal. As you might imagine, this repayment phase could feel daunting if you haven’t planned accordingly for the increase in your budget.

This is one reason many homeowners deliberately choose to pay down the principal during the draw period, even though it’s not technically required. It can dramatically reduce your financial burden in the long run and make the transition into the repayment period less jolting.

Common questions about interest-only HELOC repayment terms

Now, let’s break down interest-only HELOCs with a bit more detail to give you a better idea of how these loans might work in specific borrowing scenarios:

What is the monthly payment on a $100,000 HELOC?

For a $100,000 HELOC, assuming a 6% interest rate and a 10-year draw period, the interest-only payment during the draw phase would be approximately $500 per month.

It is important to note that this amount pays only the accrued interest and doesn’t reduce the principal owed. Once the repayment phase starts, your monthly payment will likely more than double, depending on the remaining term and interest rates, as you’ll begin repaying the principal along with the interest.

How do you calculate interest-only HELOC payments?

Calculating your interest-only payments can be tricky, but can be done by multiplying the HELOC balance by the annual interest rate and dividing that number by 12.

Just keep in mind, since most HELOCs have variable interest rates, this payment could fluctuate over time as interest rates change (and will again change once you exit the draw period).

Pros and cons of HELOC interest-only payments

Like any financial tool, interest-only HELOCs come with distinct advantages, along with some potential risks.

Far from being a cookie-cutter solution that works well for everyone, interest-only HELOCs are suitable only for certain borrowers. Understanding the advantages and disadvantages can give you a clearer picture if you happen to be one of these borrowers.

What are the advantages of interest-only home equity lines of credit?

First, the benefits:

Lower initial payments

During the draw period, you’ll only cover the interest, making monthly payments that are far smaller compared to a traditional loan. This can free up funds for other investments or expenses.

Depending on economic conditions, HELOCs tend to have lower interest rates than other types of debt, such as credit cards. During the instructional period of a HELOC, the promotional rate may be lower than that of a home equity loan. In August 2025, for example, HELOCs had average rates hovering around 8%. Even outside of home equity loans, they can be one of the cheapest ways to borrow money across the board.

Ease of access

An interest-only HELOC allows you to borrow not just how much you need whenever you need it. Unlike a standard loan that provides you with a single lump sum, you’re in control of how much of the credit line you choose to tap into (and when).

Short-term financial support

HELOCs are uniquely valuable for short-term or variable cash flow needs. You may be tackling home improvements or perhaps consolidating high-interest credit card debt. Whatever the case, interest-only HELOCs help you address your immediate goals in an accessible, practical way.

Potential tax benefits

Depending on your situation, the interest you pay on a HELOC could be tax-deductible if the funds are used for home-related expenses such as renovations. Be sure to speak to a tax professional to determine whether (and how) this applies to you.

What are the downsides of interest-only?

As with any loan, there are also some disadvantages of relying on an interest-only HELOC to help you meet your financial goals. Here are a few:

Higher payments later

One significant risk of interest-only HELOCs is the substantial increase in monthly payments after the draw period ends, as you begin repaying both principal and interest. This payment shock can strain household budgets, especially if you have not prepared for the transition.

Federal regulations require lenders to provide clear payment schedules and examples of possible payment increases, so review these carefully before proceeding.

No equity growth during the draw period

While you’re making interest-only payments, your principal balance does not decrease. As a result, you’re not building equity in your home during this time.

Variable interest rates

Most home equity lines of credit (though not all) have variable interest rates. Your payments could increase over time if market rates rise. Always check if your loan is fixed or variable before signing up for an interest-only HELOC, as this can add an element of uncertainty to the long-term affordability of your loan.

Financial discipline is required

The flexibility of interest-only HELOCs can be a double-edged sword, potentially leading to over-borrowing and financial strain. Establish a clear repayment plan and budget for possible rate increases and higher payments in the future. Federal regulations require lenders to assess your ability to repay, but personal discipline is essential to avoid excessive debt.

In summary

An interest-only HELOC can be a smart financial tool for homeowners who need flexible, low-cost access to their home equity.

That said, it’s not without its risks. If you’re a cash-strapped homeowner and expect your income to increase, this kind of loan might make sense. Similarly, if you plan to move before the HELOC draw period ends, or if interest rates are trending down long-term, you may be wise to choose this option. Otherwise, you may want to go in a different direction to avoid unnecessary risk.

If you’re curious whether an interest-only HELOC is the right choice for you, consult your lender and read all terms and disclosures carefully. The key is to carefully assess whether you can comfortably handle the shift from interest-only payments to full repayment down the line. Then, you’ll be better prepared to make a decision that aligns perfectly with your one-of-a-kind financial goals.
