Adding Calculated Fields to PivotTable

[BillCodd]

I have fields "Day", "Posts", "Impressions" in a pivot table and I need to create a new metric for the average Impressions per Post. Ideally, this new metric should function just like the other fields in the pivot table, and not just static, because I'd like to break it out not just by Day, but also Time, etc.

How can I do this?

Day Count of Posts Sum of Impressions Impressions Per Post Monday 52 1,881,468 Tuesday 81 5,339,207 Wednesday 78 4,349,817 Thursday 82 4,527,542 Friday 56 2,025,492 Saturday 47 1,620,026 Sunday 45 2,152,364 <tbody> </tbody>

Hi

Click on your pivot and "Add Calculated Field" (In 2010 it is 'Options'...'Fields items & sets'...'Calculated Field')
then...

Name: - Type the name of your 'new' field 'Impressions per post'

Formula: - Easiest way is to delete the "= 0" that shows as default then...
1. Type "="
2. Double click on the fieldname in the field list below 'Sum of impressions'
3. type "/"
4. Double click fieldname 'Count of Posts'
5. Click 'Add'
6. Click 'OK'

I say do it this way as it ensures you have the correct fieldnames (and in the single quote) in the formula. Any typo and the formula won't work.
