Performance appraisal - KRA formats with some calculations examples on the basis of increments?

I have to design performance appraisal policy. So i want some KRA formats with some calculations examples on the basis of increments will be given to employees.

KRA is Key Result Area, and KPI is Key performance index / indicator. With out KRA fixed at the beginning of the financial year, the KPI based on KRA.
For example you are fixing a KRA of 20% more profit to be achieved, and KPI could be 10% from the 'new customer' and another 10% from the 'existing customer'.
Another example is, on cost reduction of 20% KRA fixed at the beginning of the year, out of which the performer KPI could be fixed 10% from existing supplier, and 10 from the new supplier.

Its very good explaination. Thank You.
but i want some KRA and KPI format sample. how can i calculated with example.

By the way, the purpose of Performance Appraisal (PA) is not just salary increase. Just recently there was a query on PA becoming ineffective, employees just concentrated on the salary increase and did not take feedback seriously. Click the following link to refer it:
