Use this Average Percentage Calculator to calculate either a simple average or a weighted average of multiple percentages.
Calculation Methods
Use a simple average when every percentage should count equally:
Simple average = (p₁ + p₂ + … + pₙ) ÷ n
Use a weighted average when percentages represent different sample sizes, point values, credit hours, or other weights:
Weighted average = (p₁w₁ + p₂w₂ + … + pₙwₙ) ÷ (w₁ + w₂ + … + wₙ)
Example
For percentages of 82%, 76%, and 91%:
Average = (82 + 76 + 91) ÷ 3
Average = 83%
Important Note
Do not use a simple average when the percentages represent groups of very different sizes. In that case, use meaningful weights or calculate the overall percentage directly from the original totals when available.
