Average IF Within 30 days

Julie Boss

Hello,

I am trying to figure out a formula to average a particular column of information, but only within the last 30 days. I have a "Todays Date" Formula/column already created, but not sure how to write the formula to be able to read my whole column of data but only pull from the past 30 days.

I appreciate any help in advance.

Thank you,

Paul Newcome

Try something similar to...

=AVG(COLLECT([Column to Average]:[Column to Average], [Date Column]:[Date Column], AND(@cell >= TODAY(-30), @cell <= TODAY()))

Try something similar to...

=AVG(COLLECT([Column to Average]:[Column to Average], [Date Column]:[Date Column], AND(@cell >= TODAY(-30), @cell <= TODAY()))

@Paul Newcome trying to do something similar here. I am tracking go live dates, total implementation days. I want to average the total days to implement of those with a go live date in the last 90 days only. I tried: =AVG(COLLECT([Est Total Imp Days]:[Est Total Imp Days], [Go-Live Date (Actual)]:[Go-Live Date (Actual)], >TODAY(), [Go-Live Date (Actual)]:[Go-Live Date (Actual)], <=TODAY())) but am returning #DDIVIDE BY ZERO error when there are definitely go live dates within the past 90 days.

@jcouncil Your criteria for the date range would be

@cell>= TODAY(-90)

@Paul Newcome - I was hoping to attempt this on the Sheet Summary, would that still work?

@jcouncil Yes. It should still work in a sheet summary field.
