Is There a Standard Way to Calculate Salary Raises from Performance Scores? Seeking Advice!

Hi senior, is there a standard computation for salary increments based on the results of performance evaluations? Our evaluation is based on a scoring system. I would like to propose to our management a corresponding increase for the following scoring results:

EXCEEDS EXPECTATIONS (100%): 4 – 4.9

MEETS EXPECTATIONS (75%): 3 – 3.9

NEEDS IMPROVEMENT (50%): 2 – 2.9

UNACCEPTABLE (below 50%): 1 – 1.9

I would appreciate it if you could send me a sample of your computation. 

Regards,

Hi, I also want to know if there is a computation based on performance evaluation. If there is, could you teach me how? Thank you for your help.
