The array formula in B10:B13 is

=TREND(B2:B9, A2:A9, A10:A13)

Select all four of those cells, paste the formula in the formula bar, and confirm with Ctrl+Shift+Enter.

wow that was great thank you so much.

how exactly does this function? thxs alot!

 

[shg]

You're welcome.

Have a look in Help for the TREND function, and post back if there's anything you don't understand.

Hello shg

quick question. if i wanted to do the trend for the last 3 months, is that okay to do?

i.e. if i wanted a more accurate picture using the past 3 months, can i use the formula you provided but instead of counting 1-8, is it correct if i count 5-8 (months) and the respective performance?

kindly let me know. thx u

cheers

 

[shg]

Yes, you can do that. I don't know why you would consider it more accurate.

 

[bluepenink]

i should rephrase that, not more accurate but, basically im trying to understanding how many sales ppl will qualify for our year end trip (its based on their performance), so the number normally starts off high in the earlier part of the year and shrinks as the months progress.

so my senior wants to factor taking the past 3 months, cause using the full year we had a really high number.

final question, there are instances where it's going into negative.

is it possible to integrate like if trend = 0 then 0 otherwise trend?

this ismy formula for month 9 - using past 3 months
=TREND(I16:K16,I$14:K$14,L$14:$O$14)

month 10
=TREND(J16:L16,J$14:L$14,M$14:$O$14)

etc

thx u sir!
