What is cof in loan?

Written by Editorial Team | Last Updated: August 2026

"COF" in the context of loans and finance stands for "Cost of Funds." It is the interest rate that a financial institution pays to borrow the money that it subsequently lends to its customers. The Cost of Funds is a critical benchmark for banks, as it directly impacts their net interest margin—the difference between the interest income generated by their loan portfolio and the interest expense paid to fund those loans. For a borrower, understanding a bank's COF can provide insight into the institution's pricing power and its competitive position in the market. In some adjustable-rate loan agreements, the interest rate charged to the borrower may be tied to a specific "Cost of Funds Index" (COFI), meaning that as the bank's own borrowing costs fluctuate due to changes in market interest rates or the broader economic environment, the interest rate on the borrower’s loan will fluctuate as well.
