Enter the output and input values into the calculator to determine the work efficiency as a percentage. This calculator helps to evaluate the efficiency of a process or system.

Work Efficiency Formula

The following formula is used to calculate the work efficiency:

E = (O / I) * 100

Variables:

  • E is the efficiency (%)
  • O is the output (units)
  • I is the input (units)

To calculate work efficiency, divide the output by the input and then multiply by 100 to get the percentage.

What is Work Efficiency?

Work efficiency is a measure of the effectiveness of a process or system in converting input into output. It is often expressed as a percentage to indicate how much of the input is effectively turned into useful output. High efficiency means that the system or process is performing well with minimal waste, while low efficiency indicates that there is room for improvement.

How to Calculate Work Efficiency?

The following steps outline how to calculate the Work Efficiency.


  1. First, determine the output (O) in units.
  2. Next, determine the input (I) in units.
  3. Use the formula from above = E = (O / I) * 100.
  4. Finally, calculate the Work Efficiency (E) 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.

Output (O) = 150 units

Input (I) = 200 units
