Well, well, well! I apologize for not providing more info. However, I thought
it was trivial in Days Supply calculation. In any case, here is what I have:
Column C2 D2 E2 F2 G2
...........................
5-Jan 12-Jan 19-Jan 26-Jan 2-Feb .........................
Sales 2,500,000 2,900,000 2,600,000 3,200,000 2,800,000 ...................
Inventory 8,000,000 8,700,000 9,100,000 9,400,000 10,300,000
...................
Production 3,200,000 3,300,000 2,900,000 4,100,000 4,000,000
.....................
Inv+Prod 11,200,000 12,000,000 12,000,000 13,500,000 14,300,000 .............
My formula for calculating Days Supply is:
=IF(C6>SUM(C3:H3),(6+(C6-SUM(C3:H3))/I3),IF(C6>SUM(C3:G3),5+(C6-SUM(C3:G3))/H3,IF(C6>SUM(C3:F3),4+(C6-SUM(C3:F3))/G3,IF(C6>SUM(C3:E3),3+(C6-SUM(C3

3))/F3,IF(C6>SUM(C3

3),2+(C6-SUM(C3:E3))/E3,0)))))
I hope this helps.
