Count number to reach a cumulative value
How can I count the number of months it takes to reach a total of 100,000.
This would in a row count fashion from left to right. Eg. Cells A1:A7 contain sales by month. Cell A8 has a count of the number of months where the cumulative sum is equal to or greater than 100,000. So; 10000, 10000, 40000, 35000, 10000, 10000, 10000 The count would be 5 Also if 0, 0, 0, 50000, 50000, 40000,40000, 40000 The count would be 2 as it ignore 0's to the left of the first value.

Try the following array formula...
=MATCH(TRUE,SUBTOTAL(9,OFFSET(A1,,,SMALL(IF(A1:A7< 0,ROW(A1:A7)-CELL("row ",A1)+1),ROW(INDIRECT("1:"&COUNTIF(A1:A7,"0"))))) )=100000,0) ....confirmed with CONTROL+SHIFT+ENTER. Hope this helps!

I think, confirmed with control+shift+enter...
=MATCH(TRUE,SUBTOTAL(9,OFFSET(A1,0,0,ROW(A1:A7)-CELL("Row",A1)+1))=100000,0) would suffice.

Hi Aladin!
Actually, the OP asked to ignore zero values. So I think my formula may be required. Although, while the OP did say that zero values prior to the first non-zero value should be ignored, it didn't say whether subsequent zero values should be ignored as well. So maybe my formula may not be appropriate. :) In article , Aladin Akyurek wrote: I think, confirmed with control+shift+enter... =MATCH(TRUE,SUBTOTAL(9,OFFSET(A1,0,0,ROW(A1:A7)-CELL("Row",A1)+1))=100000,0) would suffice. |
I see I overlooked that...
Still less costly, therefore worth posting: Not to count empty or zero-valued cells before the first positive value in an otherwise numeric range: =MATCH(TRUE,SUBTOTAL(9,OFFSET(A1,0,0,ROW(A1:A7)-CELL("Row",A1)+1))=100000,0)-MATCH(TRUE,A1:A70,0)+1 or, if needed, to exlcude text values: =MATCH(TRUE,SUBTOTAL(9,OFFSET(A1,0,0,ROW(A1:A7)-CELL("Row",A1)+1))=100000,0)-MATCH(1,ISNUMBER(A1:A7)*(A1:A70),0)+1 The formulas still need to be confirmed with control+shift+enter.

Nice! :)
