For instance, as of May 2025, if the federal funds rate was between 4.25% and 4.50%, the prime rate would be approximately 7.50%.

Why Does the Prime Rate Matter?

The prime rate is crucial because it acts as a baseline for many consumer interest rates. Here’s why it matters:

• Variable-Rate Loans: Many credit products, such as credit cards and HELOCs, have variable interest rates tied to the prime rate. This means that as the prime rate changes, so do the interest rates on these products.

• Mortgages and Loans: Adjustable-rate mortgages and other variable-rate loans will see similar adjustments. A 0.25% increase in the prime rate would add about $25 annually for every $10,000 borrowed.
