Some applications ask for a CGPA even though your result is stated as a percentage. This tool converts a percentage into a 10-point CGPA using the commonly quoted CBSE factor, and lets you substitute your own factor when your institution uses a different one.
The formula
The conversion divides your percentage by a fixed factor:
CGPA = Percentage ÷ factor (CBSE uses 9.5)
For example, for a percentage of 78 with the CBSE factor of 9.5:
- Calculation = 78 ÷ 9.5 = 8.21
When this helps
- Applications — provide a CGPA when a form expects one but your marksheet shows a percentage.
- Eligibility checks — compare your score against a CGPA cut-off.
- Consistency — state a CGPA that lines up with a percentage you already report.
The 9.5 rule is a convention
Dividing by 9.5 is the CBSE convention for a 10-point scale, not a universal law. Other boards and universities publish their own factors or exact tables, and some do not allow a simple divisor at all. Use your institution's official rule wherever one exists, and treat this figure as an approximation otherwise. To reverse the calculation, use the CGPA to percentage calculator; to compute a percentage directly from marks, the marks percentage calculator does that.
