Explain why percentage yield may be less than 100 Example. List the known quantities and plan the problem. So to calculate it you need to divide the total revenue that the investment makes by the number of years held.
How to calculate annual percentage yield with the APY formula The APY formula divides an interest rate by the number of periods an investment compounds in a year and adds 1.
Write down the actual yield of the experiment. The theoretical yield you calculated assumes that everything went perfectly. Yield Actual yield Theoretical Yield x 100 What you need to do is to divide the ratios of both actual and theoretical yield and then multiply the answer with 100 to get the percentage. So to calculate it you need to divide the total revenue that the investment makes by the number of years held.
