Enter the cumulative frequency and the number of observations into the Calculator. The calculator will evaluate the Cumulative Percentage. 

Cumulative Percentage Formula

CP = CF / O * 100

Variables:

  • CP is the Cumulative Percentage (%)
  • CF is the cumulative frequency
  • O is the number of observations

To calculate the Cumulative Percentage, divide the cumulative frequency by the number of observations, then multiply by 100.

How to Calculate Cumulative Percentage?

The following steps outline how to calculate the Cumulative Percentage.

  1. First, determine the cumulative frequency. 
  2. Next, determine the number of observations. 
  3. Next, gather the formula from above = CP = CF / #O * 100.
  4. Finally, calculate the Cumulative 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.

cumulative frequency = 675

number of observations = 1000
