# Calculate An Average Daily Expense Cell

Feb 6, 2009I've set up a simple spreadsheet to keep track of my food expenses every month. The first column is for the date, the second is for the daily total expenses and then the next three columns are where I add the data which is then calculated into the daily total column.

I also have a total at the bottom for the entire month. Now what I want to do is I want to also have underneath the grand total, a cell which keeps track of my average daily expenses. Basically I want to divide the total expenses by the number of days which I've entered data. Now normally this would be fine but because I've applied the formula to all the cells in the expense column, it automatically lists every day as "0" rather than leaving it blank. So when it does the average calculation it's dividing my total by 30 days rather than by only the 7 days I have data for.
