What is an Index Rate and How Does It Affect Your Loans?
Definition & Meaning
An index rate is a benchmark interest rate used to determine the interest charged on variable rate loans. Unlike fixed-rate loans, where the interest rate remains constant throughout the loan term, variable rate loans have interest rates that can change periodically. The index rate serves as the foundation for calculating the interest on these loans, which means that the amount a borrower pays can fluctuate based on changes in the index rate.
Commonly used index rates include the Federal Home Loan Bank Board's cost of funds index and the National Average Mortgage Contract Rate Index. These rates are typically computed monthly and are essential for adjustable-rate mortgages, where the total payment consists of a base margin rate added to the index rate.

Legal Use & context
Index rates are primarily relevant in the context of real estate and finance law, particularly in relation to adjustable-rate mortgages and other variable rate loans. They play a crucial role in determining the financial obligations of borrowers and are often referenced in loan agreements and disclosures. Understanding index rates is essential for borrowers considering variable rate loans, as it impacts their monthly payments and overall loan costs.
Key legal elements
Real-world examples
Here are a couple of examples of abatement:
Example 1: A borrower takes out an adjustable-rate mortgage with an initial interest rate of three percent. The loan agreement specifies that the interest rate will adjust annually based on the National Average Mortgage Contract Rate Index. If the index rate rises to four percent, the borrower's new interest rate would be calculated by adding the margin rate (e.g., two percent) to the index rate, resulting in a total interest rate of six percent.
Example 2: A bank offers a variable rate loan that uses the Federal Home Loan Bank Board's cost of funds index as its index rate. If this index rate decreases, the borrower may benefit from lower monthly payments, demonstrating how index rates can directly affect loan costs. (hypothetical example)
