Enter the number of successful events and the total number of events into the calculator to determine the success ratio. The success ratio is expressed as a percentage.

Success Ratio Formula

The following formula is used to calculate the success ratio:

SR = (SE / TE) * 100

Variables:

  • SR is the success ratio (%)
  • SE is the number of successful events
  • TE is the total number of events

To calculate the success ratio, divide the number of successful events by the total number of events and then multiply by 100 to get a percentage.

What is a Success Ratio?

A success ratio is a measure of the number of successful outcomes relative to the total number of attempts or events. It is often used to evaluate the effectiveness or performance of a process, activity, or system. The success ratio is typically expressed as a percentage, indicating the proportion of successful events out of the total events.

How to Calculate Success Ratio?

The following steps outline how to calculate the Success Ratio.


  1. First, determine the number of successful events (SE).
  2. Next, determine the total number of events (TE).
  3. Next, gather the formula from above = SR = (SE / TE) * 100.
  4. Finally, calculate the Success Ratio (SR) in 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.

Number of successful events (SE) = 80

Total number of events (TE) = 200
