Folks,
In A1:A10 there are 8 values (2,4,6,8,10,12,14,16) and 2 cells with zero in each.
The average should be 9. The average I'm getting is 7.2. How does one average with zero value(s) that you do no want to be included in the average

If the cells are mathematically and legitimately zero then the average is 7.2. That is just standard mathematics.

If the cells are not relevant and just there then the formula provided above is what you need.

Ah- but you used "<>0" which is more correct if there are going to be negative values!

John,
You'd be correct if zero was part of the data stream. In this instance zero simply means that there was nothing in a particular month which would not would not be out of the ordinary.
I'd forgot that a negative value needs to be included. Although duttcome had a great solution, I'm going to go with chilternPC on this one.
