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


  • 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

Frequently Asked Questions

What is cumulative frequency?

Cumulative frequency is the sum of all frequencies up to a certain point in a data set. It helps in understanding the distribution and trends within the data.

Why is the Cumulative Percentage important in statistical analysis?

The Cumulative Percentage provides insights into the proportion of data points that fall within certain categories or intervals, allowing for easier comparison and trend analysis across different sets of data.

Can the Cumulative Percentage exceed 100%?

No, the Cumulative Percentage cannot exceed 100% as it represents the portion of the total observations up to a certain point, with the total being represented as 100%.

How can the Cumulative Percentage be used in real-world scenarios?

It can be used in various fields such as finance for analyzing cumulative returns, in education for understanding grade distributions, and in market research for analyzing customer response rates, among others.
