How it works

Understand the calculation

Useful for grades, evaluations and blended metrics where components contribute unequally.

PercentWise performs the arithmetic directly in your browser and shows a readable result without sending the numbers you enter to a server. The formula above is the core relationship used for this calculator.

Example80×30%, 90×40%, 70×30%

Weighted result = 81%

Example60×50%, 80×50%

Weighted result = 70%

Using the result

Check that the values you enter use the same units and that the reference value matches the question you are trying to answer. Different percentage formulas can look similar while using different denominators, so choosing the right calculator matters.
