Percentage to CGPA Calculator

Convert percentage to CGPA

This calculator converts an overall percentage into a cumulative grade point average, or CGPA, on the ten-point scale widely used in India. The common convention, used by the Central Board of Secondary Education, is to divide the percentage by 9.5 to obtain the CGPA, so 85 percent corresponds to a CGPA of about 8.95. The tool also gives a rough equivalent on the four-point scale used by many universities abroad, which is helpful when applying internationally.

The 9.5 factor comes from the board's observation of the average relationship between marks and grade points across subjects.

Understanding CGPA conversions

Students frequently need to move between percentages and CGPA when filling in application forms, comparing results or meeting eligibility criteria stated in one system or the other. The divide-by-9.5 rule is a quick, widely accepted approximation for the ten-point scale, though individual institutions may publish their own exact conversion tables.

The four-point GPA estimate here is a simple proportional approximation; universities often use detailed grade-band tables instead, so use it only as a rough guide. Always check the specific conversion required by the institution you are dealing with. All calculation happens locally in your browser.
