As of September 3, 2026, the average interest rate for a home equity line of credit (HELOC) is 8.09%, according to Money.com. A HELOC is a type of loan that allows homeowners to borrow against the equity in their homes, typically with a variable interest rate that can change over time. Because the rate can fluctuate monthly, it makes it harder for borrowers to predict their monthly payments or total repayment amounts. For example, if someone takes out a $150,000 HELOC and repays it over 10 years, their monthly payment would be around $1,827. If they choose a longer 15-year repayment period, the payment would drop to about $1,441, assuming the rate remains the same and the full amount is borrowed and repaid. In October 2025, when interest rates were lower, a 10-year HELOC at 7.89% would have required a monthly payment of $1,811.21, while a 15-year HELOC at the same rate would have cost $1,423.97 per month. However, by July 2025, rates had risen slightly, and a 10-year HELOC at 8.27% would have cost $1,841.38 per month, with a 15-year HELOC at that rate costing $1,456.96. This shows that even small changes in interest rates can affect monthly payments significantly. Currently, HELOC payments are lower than they were in the summer of 2025 but higher than they were in the fall of 2025. This fluctuation highlights the uncertainty that comes with variable-rate loans. Homeowners are encouraged to plan carefully, factoring in the potential for future rate changes that could affect their monthly budgets or the total amount paid over time. Despite this uncertainty, HELOCs can still be a cost-effective way to borrow large sums, especially when used wisely and repaid strategically. Experts suggest that borrowers should consider their financial goals and repayment plans before taking out a HELOC. While the variable rate introduces risk, the flexibility of a HELOC can make it a useful tool for managing large expenses, such as home improvements or medical costs. Borrowers should also be aware of the potential for higher payments in the future and ensure they can handle any changes in their monthly obligations.
