average that includes estimates if data not available
I need a formula that totals 12 cells in a row ( the row is monthly sales)
for an annual total. However if the row doesn't have a full 12 months worth of data I need to estimate the annual sales by taking an average of the available months and multiplying them by 12. (the available months will vary on each row- some may have only the first 3 months or 7 months etc) Thanks for any help on this. -- Billy Rogers Dallas,TX Currently Using SQL Server 2000, Office 2000 and Office 2003 |

With your months in say B2:M2, then in N2 =SUM(B2:M2). In O2
=COUNTIF(B2:M2,"") to count the number of months with totals, and in P2 =N2/(12-O2)*12 -- Hth Kassie Kasselman Change xxx to hotmail "BillyRogers" wrote: I need a formula that totals 12 cells in a row ( the row is monthly sales) for an annual total.

One way (assuming the cells without data are blank):
=AVERAGE(A1:L1)*12 In article , BillyRogers wrote: I need a formula that totals 12 cells in a row ( the row is monthly sales) for an annual total.
