If you are running a Windows version of SAM, you can also see the calculation in Excel by clicking Send to Excel with equations from the Cash Flow tab on the Results page. We have also posted versions of this Excel workbook on the SAM website at sam.nrel.gov/financial-models/residential-and-commercial.html.
Sir, I am unable to understand Excel sheet formula (IF function) for Simple Payback Period. Can u please teach me how to calculate payback period? can you please write the formula here with explanation? Please.
The equations are described in the Help topic I provided a link to above. Please also see the Short (1995) publication mentioned at the beginning of that topic.
