About Average Percentage Calculator
An average percentage calculator helps you combine several percentage values into one clear result. Instead of calculating each value manually, you can enter all percentages in one place and instantly get the average. This is helpful when comparing academic performance, sales growth, attendance rates, project completion, survey results, or any percentage-based data.
The tool also supports optional weights. A weighted average is useful when each percentage does not have the same importance. For example, a final exam may carry more weight than a quiz, or one business metric may be more important than another.
Average Percentage Formula
To calculate a simple average percentage, add all percentages together and divide the total by the number of values.
Example: 80%, 90%, and 70% gives: 240 ÷ 3 = 80%.
Weighted Average Formula
A weighted average gives more importance to selected values. Multiply each percentage by its weight, add the results, then divide by the total weight.
This is best for grades, reports, evaluations, and performance calculations.
