The amount of interest you will pay on a home improvement loan can vary depending on various factors such as the loan amount, term, interest rate, and your creditworthiness. Typically, home improvement loans have fixed interest rates that range from 5% to 36%. If you have good credit, you may qualify for a lower interest rate, which means you'll pay less in interest over the life of the loan. On the other hand, if your credit is not as strong, you may end up with a higher interest rate and thus pay more in interest. It's essential to shop around for different loan options and compare interest rates to ensure you're securing the best possible deal.
