CGPA to Percentage Calculator
Convert CGPA to percentage free with the CBSE 9.5, standard 10-point or VTU formula — plus percentage back to CGPA, and CGPA from grade points and credits.
Percentage = CGPA x 9.58.20 CGPA → 77.90%CBSE derived the 9.5 multiplier from the average marks of students in its top grade band (91-100), whose grade point is 10. A perfect 10.0 therefore maps to 95%, not 100%.
The 4.0-scale figure is a straight linear map (CGPA / 10 x 4) shown for reference only, and only for a 10-point CGPA. Credential evaluators such as WES and individual admissions offices apply their own grade tables, so use the number on their conversion, not this one, for applications. Conversion rules differ by board and university — always check your marksheet or academic regulations first, and pick “Custom multiplier” if yours is not listed.
Frequently asked questions
- Which CGPA to percentage formula should I use?
- The one your own board or university publishes, because there is no single national rule. CBSE and CISCE multiply the CGPA by 9.5; many 10-point universities multiply by 10; VTU subtracts 0.75 first and then multiplies by 10. All three are in the dropdown, and if yours uses a different multiplier — a 4-point scale, for instance, where the equivalent is 25 — pick 'Custom multiplier' and type it in.
- How do I calculate CGPA from grade points and credits?
- Switch to the 'Grades → CGPA' tab and enter one row per subject with its grade point and credit value. The CGPA is the credit-weighted average: multiply each grade point by its credits, add those products up, and divide by the total credits. The same arithmetic gives SGPA when the rows are the subjects in one semester, and CGPA when the rows are your semesters weighted by their credits.
- Is the 4.0-scale GPA accurate for university applications?
- No — treat it as a rough orientation figure only. It is a straight linear map (CGPA divided by 10, times 4), while credential evaluators such as WES and individual admissions offices apply their own grade-band tables that are rarely linear. Send them your official transcript and use whatever number their conversion produces.
