Calculate Average Marks Percentage Now! →Understanding the Basics
At its core, a percentage represents a portion of a whole, with 100% representing the entire amount. Calculating the average percentage involves finding the arithmetic mean of a set of percentages.
Simple Average Percentage Calculation
When dealing with a set of percentages where each percentage carries equal weight (e.g., percentages from tests with the same maximum score), the calculation is simple:
- Add up all the percentages.
- Divide the sum by the number of percentages.
Example: Suppose you scored 75%, 80%, and 90% on three exams. The average percentage is (75 + 80 + 90) / 3 = 81.67%. Why not use our percentage calculator above to work this out?!
Weighted Average Percentage Calculation
In many real-world scenarios, percentages do not carry equal weight. For instance, different subjects may have different credit hours, or assignments may have varying point values. In these cases, you'll need to calculate a weighted average percentage.
- Multiply each percentage by its corresponding weight.
- Add up all the weighted percentages.
- Divide the sum of the weighted percentages by the sum of the weights.
Example: Consider a student with the following grades:
- Math: 90% (4 credits)
- English: 85% (3 credits)
- Science: 88% (3 credits)
The weighted average percentage is calculated as follows: [(90 * 4) + (85 * 3) + (88 * 3)] / (4 + 3 + 3) = 87.9%. Alternatively, input the values into our tool at the top of the page for instant calculations!
