How to calculate payback period in excel
The payback period is an important financial metric that helps businesses and investors evaluate the feasibility of an investment or project. It represents the time it takes for an investment to recover its initial cost. Excel serves as a powerful tool for calculating the payback period. In this article, we’ll demonstrate step-by-step how to calculate payback period using Excel.
Step 1: Organize your data
Begin by organizing your data in a clear and easy-to-read format. In Column A, list the years or periods for your investment/project. In Column B, input the respective cash flows for each period.
Step 2: Calculate cumulative cash flow
To calculate the payback period, it’s essential to determine the cumulative cash flow for each period. In Column C, perform this calculation as follows:
1. For the first row (usually C2), enter ‘=B2’ and press Enter.
2. For subsequent rows down Column C, input ‘=C(column-1)+B(row)’ formula.
3. Fill down the formula until to cover all rows.
Step 3: Identify when cumulative cash flow becomes positive
Create a new column (Column D) and input a formula that identifies when cumulative cash flow turns positive compared to initial investment.
1. In D2 cell, enter ‘=IF(C2>0,”Positive”,”Negative”)’
2. Drag down the formula to copy it for other corresponding cells.
Step 4: Calculate payback period
In this step, we will calculate the payback period based on our inputs and calculations so far.
1. Select an empty cell for your Payback Period calculation (for example E1)
2. Enter the following formula ‘=INDEX(A:A,(MATCH(“Positive”,D:D,0)))’
3. Press Enter.
This formula locates the first instance of “Positive” in Column D and retrieves the corresponding year/period from Column A.
Step 5: Fine-tune your calculation (Optional)
If you need to calculate the payback period more accurately to account for in-between periods, follow these additional steps:
1. In cell E2, insert this formula ‘=(INDEX(A:A,MATCH(“Positive”,D:D,0))-1)+((0-
INDEX(C:C,MATCH(“Positive”,D:D,0)-1))/(INDEX(B:B,MATCH(“Positive”,D:D,0))))’
2. Press Enter.
This formula calculates the difference in cumulative cash flow (between “Negative” and “Positive”) and divides it by the cash flow of the first positive period to determine any partial period within the payback.
Conclusion:
Calculating the payback period using Excel is an efficient way to evaluate investment opportunities or business projects. Mastering this method will allow you to make better financial decisions and increase overall business success.
