Marks Percentage Calculator
Convert marks obtained across subjects into an overall percentage.
About the Marks Percentage Calculator
List each subject on its own line with the marks you got and the maximum marks, for example “Maths 92 100”. The calculator adds them up and gives your overall percentage.
When subjects have different maximums, this weights each by its maximum, which is how boards and universities usually calculate it.
The formula
Percentage = Σ marks obtained ÷ Σ maximum marks × 100
Worked example
Five subjects out of 100 each: 78, 92, 85, 74, 81
- Total: 410 out of 500
- 410 ÷ 500 × 100 = 82%
Things to keep in mind
- Grace marks and moderation are not applied; enter the final marks shown on your mark sheet.
