The annual rate of earnings on an investment equates the value of cash returns with the cash invested,taking into consideration the power of compounding interest.The following formula requires a trial-and-error method for solution.

Using this formula,CF is the cash flow in each period,with one subpart of the formula for each investment year until you reach n,the final year of the investment.You have to solve for R, the annual rate, by trial and error.
