Marks to GPA, done right
Convert your marks into percentage, CGPA and grade for CBSE, ICSE and State Boards.
How the calculator works
Enter your marks obtained and the total marks. The percentage updates live, and the board you choose decides how it maps to a CGPA and grade. For CBSE, the widely used rule is percentage ÷ 9.5 = CGPA.
Use it to sanity-check a report card, set a target for the next unit test, or convert a percentage back into the grade band your board uses.
Common questions
How is CBSE CGPA calculated?
CBSE uses a 9.5 multiplier: your overall percentage divided by 9.5 gives an approximate CGPA. This tool applies that rule automatically when you pick CBSE.
Does this work for ICSE and State Boards?
Yes. Percentage is the same everywhere; the grade and GPA estimate adjust to the board you select.
Is my data saved anywhere?
No. The calculation runs entirely in your browser — nothing is uploaded or stored.
