Compa Ratios
Using Excel to calculate Compa Ratios:
Compa ratio (CP) is a salary expressed as a percentage of or indexed to the salary range midpoint/market rate (salary/midpoint or market rate = compa ratio).
The CP may be used as an indicator of how an individual is doing against plan. If the CP = 100, the salary of the individual is equal to the midpoint/market point (MP/MR). This may also be used to assess incumbents in a job, job family or entire organization by dividing the collective salaries by the collective MP/MR.
When the CP is significantly below 100, an increased risk of turnover exists. Conversely, if the CP is significantly above 100 you may be overpaying and driving unnecessary costs into the business. If your CP is significantly above 100 and turnover is high, check your source of market data and look for other contributing factors.

Use the following formula in F2:F9 to calculate Compa ratio based on Mid point of grade in above table:
=(1+((E2-VLOOKUP(A2,$A$14:$D$19,3,FALSE)))/(VLOOKUP(A2,$A$14:$D$19,3,FALSE))))*100 |
