Percentage to CGPA Calculator
Convert percentage marks into CGPA on a 10, 5 or 4-point scale using the ÷9.5 rule, a proportional formula or your own divisor, with the working shown.
How this was calculated
78 ÷ 9.5 = 8.21
Percentage-to-CGPA conversion is not standardised, and admissions offices often insist on their own formula. Treat this as an estimate and confirm with your institution. Nothing you type leaves your device.
What is the Percentage to CGPA Calculator?
To convert a percentage into CGPA, divide your percentage by the factor your institution uses — commonly 9.5 for a 10-point scale — or divide by 100 and multiply by the scale maximum for a proportional result.

About the Percentage to CGPA Calculator
The ByteTools Percentage to CGPA Calculator does the reverse of the usual conversion: you have marks out of 100 and need a grade point average for an application, a transfer form or a foreign university portal. Enter your percentage, pick the scale and the formula, and the CGPA appears with the arithmetic beside it.
Three methods are built in — divide by a factor such as 9.5, convert proportionally against the scale maximum, or add a fixed offset after dividing by ten. Each mirrors a rule published by a real board or university, and every number in them is editable so you can match your own regulations exactly.
The tool checks your input, refuses percentages above 100 and flags any result that lands above the scale you chose, which almost always means the divisor belongs to a different system. It runs entirely in your browser and nothing you enter is uploaded.
Frequently asked questions
How do I convert percentage to CGPA?
Divide your percentage by 9.5 if your institution follows the CBSE convention — 76% becomes 8.0 CGPA. For a proportional conversion, divide by 100 and multiply by the scale maximum, which turns 76% into 7.6 on a 10-point scale.
What is 75 percent in CGPA?
Using the ÷9.5 rule, 75% is a CGPA of 7.89. A proportional conversion on a 10-point scale gives 7.5, and the (percentage ÷ 10) + 0.75 rule gives 8.25. Pick whichever your institution publishes.
Is percentage to CGPA conversion accurate?
It is an approximation. Grade points are awarded band by band, so two students with the same percentage can hold different CGPAs. Treat the result as an estimate and quote the CGPA on your transcript wherever one exists.
How do I convert percentage to GPA on a 4.0 scale?
Set the target scale to 4 and use the proportional method: 85% becomes 3.4. Many US universities instead map percentage bands to letter grades first, so check whether the institution wants a band-based conversion.
Which formula should I use on an application form?
Use the one printed in your university's regulations or on the back of your marksheet. If none is given, state both the percentage and the conversion method you used — admissions offices prefer transparency over a bare number.
