Enter the total parts and the whole amount into the Calculator. The calculator will evaluate the Parts To Percentage. 

Parts To Percentage Formula

PTP = P / W * 100


  • PTP is the Parts To Percentage (%)
  • P is the total parts
  • W is the whole amount

To calculate Parts To Percentage, divide the number of parts by the total amount, then multiply by 100.

How to Calculate Parts To Percentage?

The following steps outline how to calculate the Parts To Percentage.

  1. First, determine the total parts. 
  2. Next, determine the whole amount. 
  3. Next, gather the formula from above = PTP = P / W * 100.
  4. Finally, calculate the Parts To Percentage.
  5. 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.
