Percent Increase calculation

[uvic_coop]

A report I'm generating features four columns: year1, year2, difference and percent increase. difference is simply year2 - year1, while percent_increase is (year2 - year1)/year1.

Subtotals for year1, year2 and difference are no problem using summary fields. However, I'm unsure how to calculate percent_increase per subtotal. (Using summary fields *adds* percent_increase values, which I don't want.)

Any suggestions?

You will need to define what you want the percent increase to mean across a number of records. One way is to add up the percents of increase and divide by the number of records. This will give an AVERAGE percent increase. Another way is to perform your calculations on the totals for year1 and year2. It greatly depends on what the numbers represent as to whether either gives a meaningful result. -bd
