Relative Percentages
Many areas of Gaidge use a relative percentage, this calculates the percent of the current month completed, takes that percentage of the same month last year and compares it to this month's value.
Math
Go to your Monthly Summary
In our example we are looking at June through the 12th.
For the RELCHG percentage: 12/30 = .4 * 100 → 40%
To get the number for 40% of SMLY Net Prod: 468,556 * .40 = 187,422.40
This month divided by SMLY %: 185,087 / 187,422.40 = 0.9875
If this is less than one subtract from 1:
1 - 0.9875 = 0.0124 ... multiply by 100 → 1.2%
Please note that your numbers may be slightly off due to rounding.
