Enter the sum of days supply and the number of days into the Calculator. The calculator will evaluate the MPR. 

MPR Formula

MPR = SDS / D *100


  • MPR is the MPR (%)
  • SDS is the sum of days supply
  • #D is the number of days

To calculate MPR, divide the sum of days supply by the number of days, then multiply by 100.

How to Calculate MPR?

The following steps outline how to calculate the MPR.

  • First, determine the sum of days supply. 
  • Next, determine the number of days. 
  • Next, gather the formula from above = MPR = SDS / #D *100.
  • Finally, calculate the MPR.
  • After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

sum of days supply = 50

number of days = 4
