In this example, we want to calculate the annual interest rate for 5-year, $5000 loan, and with monthly payments of $93.22. The RATE function is used like this: The function arguments are configured as follows: nper - The number of periods is 60 (5 * 12), and comes from cell C7. pmt - The payment is $93.22, and comes from cell C6. Note pmt is input as a negative value. In annuity functions, cash paid out is represented by a negative number. Note: If pmt is not provided, the optional fv argument must be supplied. pv - The present value is $5000, and comes from C5.  With these inputs, the RATE function returns 0.375%, which is the periodic interest rate. To get an annual interest rate, we multiply by 12: With the percent number format applied to cell C10, the result is displayed as 4.50%.
