You can add custom fields to your reports by clicking on the Custom Field menu. Choose "Create Custom Measure" to create a custom number, "Create Custom Grouping" to create a custom text field, or "Create Custom Date" to create a custom date:
Once in the custom field editor, you'll first need to give the custom field a name.
After giving the field a name, you need to create a calculation for the custom field. For example, you might calculate sell through rate value by doing stock subtracted - (stock level start + stock added) * 100 as in the example below:
You can drag fields from the lefthand field tree into the calculation area to simplify things. Highlighting below the calculation area will show possible errors in red to help you track down syntax problems.
After you click on Save to create the calculation, the new field will be available under Report Custom Fields. You can also do Save and Add to Report to immediately add the new field to your report. You can add it to your report like any other field at this point.

After the report is run, you can click on a cell in the report and do 'Explain Value':
