Percentage to CGPA Calculator
Convert marks into a grade point average instantly. This free percentage to CGPA calculator uses the standard CBSE rule — CGPA = Percentage ÷ 9.5 — and lets you swap in a different divisor if your university publishes its own. It also estimates the US 4.0-scale GPA that overseas applications ask for. Everything runs in your browser, so nothing you type is uploaded.
How to use it
- Type your percentage in the first card to get the CGPA on a 10-point scale.
- Change the divisor if your institution uses something other than 9.5.
- Applying abroad? Enter the percentage in the second card for the 4.0-scale GPA and letter grade.
- Check the reference table — the band matching your entry is highlighted as you type.
How percentage converts to CGPA
CGPA, or Cumulative Grade Point Average, is the average grade point across all your subjects, normally on a 10-point scale. Because CBSE converts a grade point to marks by multiplying by 9.5, going the other way simply reverses it: divide the percentage by 9.5. A student scoring 76% therefore has a CGPA of 76 ÷ 9.5 = 8.0, and 95% maps to the maximum 10. The 9.5 figure comes from the average of the upper and lower marks of the top five CBSE grade bands.
This rule is a CBSE convention, not a universal law. Plenty of universities divide by 10, subtract a constant first, or publish a conversion table with fixed bands rather than a formula. Anna University, VTU, Mumbai University and many autonomous colleges each define their own. Before you write a CGPA on an application form, check the formula printed on your marksheet or in the academic handbook — the custom divisor above exists exactly so you can match it.
A caution about the 4.0 GPA conversion
The 4.0-scale figure on this page is an estimate, not an official conversion, and it is worth understanding why. American letter grades were designed around American marking, where 90% is routine and a first class is well above 80%. Indian marking is stricter in many subjects, so a 65% from an Indian engineering programme can represent stronger work than the same number would in the United States. That is why credential evaluators such as WES, and individual admissions offices, use their own conversion tables and often assess your transcript grade by grade rather than from a single percentage. Use the number here to get a rough sense of where you stand, but always submit the official evaluation your target university asks for.
