Average Percentage Calculator

Calculate the average of multiple percentages instantly. Enter two or more percentage values to find their average.

Minimum: 2 percentages. Example values are pre-filled; replace them with your own.

This calculator finds the simple average of percentages. If your percentages represent different total marks, credits, or weights, a weighted calculation may be more appropriate.

What Is an Average Percentage?

An average percentage is found by adding several percentage values and dividing the sum by the number of values. It gives a single representative percentage from multiple equal-weight percentages.

How to Calculate the Average of Percentages

The formula is:

Average Percentage = Sum of Percentages ÷ Number of Percentages

Example:

Percentages: 80%, 90%, and 75%

(80 + 90 + 75) ÷ 3 = 245 ÷ 3 = 81.67%

Average Percentage Example

Suppose you have three test scores:

Test	Percentage
Test 1	80%
Test 2	90%
Test 3	75%

The average is:

(80 + 90 + 75) ÷ 3 = 81.67%

Can You Average Percentages Directly?

Yes, you can directly average percentages when each percentage has equal importance or is based on the same total. For example, three equally weighted test scores can be averaged using the simple average formula.

However, if the percentages come from different total marks or have different weights, a simple average may be misleading.

When Should You Use a Weighted Average?

Use a weighted average when the percentages are based on different total marks, credit hours, or weights. For example, if one test is worth 100 points and another is worth 200 points, a simple average of their percentages does not reflect the actual overall performance. In that case, you would need to combine the actual marks. Our Weighted Grade Calculator can help with weighted grade calculations.

Average Percentage vs Overall Percentage

Average percentage treats each percentage equally.

Overall percentage may depend on total marks. For example:

Test 1: 80/100 = 80%
Test 2: 90/200 = 45%

Simple average of percentages: (80 + 45) ÷ 2 = 62.5%

Actual overall percentage: (80 + 90) ÷ (100 + 200) × 100 = 56.67%

This shows why simple averaging can be misleading when totals differ.

Frequently Asked Questions

How do you calculate the average percentage? +

Add all the percentage values together, then divide by the number of percentages. For example, (80 + 90 + 75) / 3 = 81.67%.

Can I average more than two percentages? +

Yes, you can average any number of percentages. Enter them all in the calculator and it will compute the average.

Can percentages include decimals? +

Yes, the calculator accepts decimal values like 87.5 or 92.25. They are handled correctly.

Can you simply average percentages? +

Yes, when all percentages have equal weight (e.g., equally weighted test scores), you can simply average them by adding and dividing by the count.

What is the average of 80%, 90%, and 70%? +

The average is (80 + 90 + 70) / 3 = 240 / 3 = 80%.

What is the difference between an average percentage and an overall percentage? +

Average percentage treats each percentage equally. Overall percentage may depend on total marks or weights; if the bases differ, you need a weighted calculation.

When should I use a weighted average instead? +

Use a weighted average when percentages represent different total marks, credits, or importance. This calculator is for simple equal-weight averages.
