Question

I have a table set up with Employee Start Date, Termination Dates and then monthly columns - see image below.

I am trying to calculate the Employee Tenure but based on the following scenarios:

1. An employee has started within the month or is currently employed and has no termination date - Tenure will calculate as normal with Start Date and reporting month (columns CF, CG etc)

2. An employee has terminated - Tenure will calculate with Start Date and reporting month until Termination month and then swap to calculation between start and termination date (columns E, F). Once the termination month has passed the tenure will be 0 for that employee. eg. Start 11-Jan-16, Termination 8-Jul-16, Column CF (June) & CG (July) will calculate as normal and Column CH (Aug) should be 0.

Here is an image of my current worksheet set up:

The formula I have currently is:

=IF(OR(CF$2>CurrentReportMonth,$E9>CF$2),0,IF($F9>CF$2,0,IF(OR($E9<=CF$2,$F9<CF$2),DATEDIF($E9,CF$2,"M"),DATEDIF($E9,$F9,"m"))))

Answer 1

Here is the summary of our discussion:

=IF(OR(CF$2>ReportDate,AND($F9>0,$F9<CF$2),$E9>=CF$2),"-",IF(AND($E9<=CF$2,$F9=0‌​),DATEDIF($E9,CF$2,"M"),IF(AND($E9<=CF$2,$F9>CF$2),DATEDIF($E9,CF$2,"M"),DATED‌​I‌​F($E9,$F9,"M"))))

Use this formula at cell CF9 and copy up and down, and that should get the result.

Answer 2

Try this:

=IF($A25>$F$24,0,IF(AND(LEFT(CELL("format",$B25),1)="D",$B25<$F$24),0,IF(ISNUMBER(F25),F25+1,1)))

NOTE :
My data setup in the file:

• Column A = Start Date
• Column B = Termination Date
• I had my monthly dates starting from column E

You will have to adjust the column names as per your worksheet but this should give you the results you want
