How It Works
To find the average of a set of percentages, you add them all together and divide by how many values there are. This is the arithmetic mean, the same method used for finding the average of any set of numbers.
The Formula
Average = Sum of Percentages ÷ Number of Values
When to Use This
Averaging percentages is useful when you want an overall picture from several percentage readings, for example: averaging test scores, survey response rates, monthly growth rates, or conversion rates across different channels.
Note: a simple average of percentages is only meaningful when each percentage is based on the same sample size. If the underlying totals differ significantly, a weighted average may be more appropriate.
Worked Examples
Example 1: Three test scores
Scores: 70%, 85%, 90%. Sum = 245. Average = 245 ÷ 3 = 81.67%
Example 2: Four survey response rates
Rates: 45%, 60%, 55%, 70%. Sum = 230. Average = 230 ÷ 4 = 57.5%
Example 3: Two conversion rates
Rates: 3.2%, 4.8%. Sum = 8. Average = 8 ÷ 2 = 4%
Example 4: Five monthly growth rates
Rates: 2%, 5%, 3%, 8%, 7%. Sum = 25. Average = 25 ÷ 5 = 5%
Example 5: Three discount rates
Discounts: 10%, 15%, 25%. Sum = 50. Average = 50 ÷ 3 = 16.67%
