How to calculate percentage of marks

Published 3 October 2026. Last updated 3 October 2026.

Whether it is a board result, a university transcript or a job form asking for your percentage, the calculation is the same.

The formula

Percentage = marks obtained ÷ total marks × 100

Examples

Marks obtainedTotal marksWorkingPercentage
8501100850 ÷ 1100 × 10077.27%
432550432 ÷ 550 × 10078.55%
687568 ÷ 75 × 10090.67%

Rounding

Most forms ask for two decimal places. Keep the full number while you calculate and round only at the end, otherwise small errors add up.

Two other everyday percentages

A percent of a number: multiply the number by the percent and divide by 100. A 15% discount on 2,400 is 2,400 × 15 ÷ 100 = 360.

Percentage change: subtract the old value from the new one, divide by the old value and multiply by 100. A salary that rises from 50,000 to 60,000 has gone up by 20%.

Converting a CGPA

Each university sets its own rule for turning a CGPA into a percentage, so there is no single formula that works everywhere. Check your university's transcript or website for the method it uses.
