A typical home equity line of credit tends to have a variable rate that changes based on market conditions. However, some lenders allow you to lock in a fixed APR, meaning that you'll continue to pay the same rate for each fixed withdrawal. Fixed-rate and variable-rate HELOCs each have their own advantages, so compare lender options before deciding.

Fixed rates vs. variable rates

A typical HELOC has an introductory rate that increases or decreases based on market conditions. As these loans can last for decades, it’s difficult to predict how your rate will change. Lenders have ceilings for APR (usually around 18%), but it’s unlikely you’ll ever pay the maximum.

Still, some people are uncomfortable with this level of uncertainty. Fixed-rate HELOCs allow you to lock in some or all of your loan at a specific APR, giving you predictable payments. If you choose to freeze the APR for part of the loan only, the rate will vary for subsequent draws.

Lenders each have their own guidelines around fixed-rate HELOCs, so it’s important to read the fine print. Bank of America, for instance, requires a minimum outstanding balance of $5,000 to convert from a variable rate to a fixed one. You also may be limited in the number of times you can choose a fixed-rate option. For example, Truist allows for a maximum of five open fixed-rate withdrawals at a time.

Pros of getting a fixed-rate HELOC

For risk-averse borrowers exploring HELOC options, there are benefits to selecting a fixed rate that are worth considering.

  • Fixed-rate HELOCs safeguard your loan from rising interest rates. This can save you money in the long run if interest rates go up.

  • You know exactly what you’ll be paying, making long-term financial planning easier.

  • Some lenders allow you to revert to a variable rate if rates go down, so locking your APR doesn’t necessarily mean gambling on a rate increase.

Cons of getting a fixed-rate HELOC

Borrowers who want to maximize lender options and avoid high introductory costs may opt for a variable rate instead.

  • Fixed-rate options could have a higher initial APR than variable-rate HELOCs. If you think that you’ll be paying off your HELOC quickly, the risk mitigation offered by a fixed rate may not be worth this pricier fee.

  • You’re limited in your lender selection, since not all HELOC lenders offer a fixed-rate option.

  • You may be limited in the number of times that you can lock a rate.

How to get a fixed-rate HELOC

Fixed-rate options are a unique feature that not every HELOC lender will offer. Out of nearly 20 lenders surveyed by NerdWallet, about half confirmed that consumers could lock in their loan at a fixed rate. If a fixed-rate HELOC is something that you want (or may want), you should ask about it when getting quotes from potential lenders. NerdWallet’s roundup of the best HELOC lenders is a good place to start your search. It notes which lenders offer a fixed-rate option.

Once you get a HELOC, the window to withdraw from your equity (known as the draw period) usually lasts around 10 years. The repayment period varies depending on the lender and the terms of your loan, but it can be as long as 20 or even 30 years.
