To calculate an average percentage, you first add up all the individual percentages you want to average. Then, divide that total by the number of percentages you added together. This gives you the average.

For example, if you have three percentages like 70%, 80%, and 90%, you add them up (240) and then divide by 3, which gives you an average percentage of 80%.

In this article, we will learn about Average Percentage and it's calculation in detail.

Average Percentage Formula

An average percentage is the mean of multiple percentage values. It's calculated by summing the individual percentages and then dividing by the number of values.

Average Percentage = Sum of All Percentage/ Number of Items × 100

For example - If you have three percentages: 50%, 60%, and 70% then the average percentage would be:

Average Percentage = (50% + 60% + 70%)/3 = 180% / 3 = 60%

Note: It's important to note that if you're working with different-sized groups (for example, percentages representing different total amounts), you may need a weighted average instead of a simple average.

Steps to Calculate Average Percentage

We can use the following steps for calculating the Average Percentage:

Step 1: Gather the Percentages Identify all the percentages you want to calculate the average for. Let's assume we have the following percentages:

  • 50%
  • 75%
  • 60%

Step 2: Convert Percentages to Decimal Form (Optional)If preferred, you can convert percentages to decimals for easier calculations:

  • 50% = 0.50
  • 75% = 0.75
  • 60% = 0.60

This step is not always necessary because percentages can be calculated directly.

Step 3: Add the Percentages Add all the percentages together:

  • 50% + 75% + 60% = 185%

Step 4: Count the Number of Percentages

Determine how many percentages are involved. In this case, there are 3 percentages.

Step 5: Divide the Total by the Number of Percentages

  • Divide the total sum of percentages by the number of percentages:( \frac{185%}{3} = 61.67% )
  • Final Result The average percentage is 61.67%.

Conclusion

In conclusion, calculating the average percentage is a simple process that helps us understand overall performance or trends. All you need to do is add up the individual percentages and divide the total by the number of percentages.
