This is the classic type of problem that we can quickly approximate using the Rule of However, we can easily find the exact answer using the NPer function. As the name suggests, this function is designed to solve for the number of periods and is defined as:.
NPer ratepmtpvfvtype. Select B5 and type: You can see that it will take 8. One important thing to note is that you absolutely must enter your according to the cash flow sign convention. If you don't make either the PV or FV a negative number and the other one positivethen you will get a NUM error instead of the answer.
That is because, if both numbers are positive, Excel thinks that you are getting a benefit without making any investment. If you get this error, just fix the problem by changing the sign of either PV or FV.
