CGPA Calculator

CGPA (Cumulative Grade Point Average) is a 10-point scale used by the Central Board of Secondary Education (CBSE) to express a student's overall academic performance across subjects. This calculator converts CGPA to an indicative percentage (and vice versa) using the official CBSE multiplier of 9.5.

CBSE defines the conversion formulas as:

• Overall indicative percentage = 9.5 × CGPA
• Subject-wise indicative percentage = 9.5 × Grade Point of the subject

Enter your grade points for up to five main subjects (or your overall CGPA) and the tool instantly shows the corresponding indicative percentage. For the reverse direction, type a percentage figure to see the equivalent CGPA.

The 9.5 multiplier originates from CBSE's Continuous and Comprehensive Evaluation (CCE) scheme, which graded Classes 9 and 10 on a point scale from 2010 until it was discontinued after the 2017–18 academic year. CBSE now reports results in percentage for all classes; however, the 9.5 formula continues to apply to older mark sheets and any CGPA-based results still in circulation for Classes 9, 10 and 12.

Per CBSE, CGPA is the average of the grade points of your five main subjects. Enter your main subjects first, choose a grade for each, and the calculator averages those five grade points and multiplies by 9.5 for the indicative percentage. A sixth or seventh subject is treated as an additional subject and is excluded from the CGPA — CBSE excludes the designated additional subject, not whichever subject scored lowest. Main subjects are outlined in green; additional (excluded) subjects in amber, so you can see exactly which grades drive your result.

• Grade points: A1 = 10, A2 = 9, B1 = 8, B2 = 7, C1 = 6, C2 = 5, D = 4. Grades E1 and E2 are failing grades (grade point 0).
• An E1/E2 in a main subject marks it Eligible for Improvement of Performance (EIOP). The same grade in an additional subject is excluded and needs no improvement exam.
• You can rename any subject, and two subjects may share the same name; every row you grade is counted independently.

Since 2010, CBSE stopped declaring “Pass / Compartment / Fail” at the secondary level. The Statement of Subject-wise Performance now shows one of two results (CBSE Circular No. 24 / 28-05-2010):

• QUAL — Eligible for Qualifying Certificate. You obtained the qualifying grade (minimum grade D) in all main subjects, excluding the additional 6th subject. You are eligible for admission to higher classes.
• EIOP — Eligible for Improvement of Performance. You obtained grade E1 or E2 in one or more main subjects (again excluding the additional 6th subject) and must improve those subjects.

A candidate eligible for Improvement of Performance can reappear to improve any or all of the E1/E2 subjects — CBSE allows up to five chances until grade D or above is secured in every main subject. There is no limit on the number of E-grade subjects that bars you from improving; you are always eligible to reappear.

This CGPA calculator works for any 10-point grading scale, which most Indian boards and universities use. CGPA itself is calculated the same way everywhere: the average of grade points earned across subjects or semesters.

The CGPA-to-percentage conversion factor, however, varies by institution. CBSE specifies 9.5; many universities multiply by 10; others define their own formula, such as (CGPA − 0.75) × 10. If you are converting a university CGPA, check the conversion rule printed on your marksheet or published by your institution. The 9.5 figure on this page is the official CBSE multiplier and applies to CBSE Class 9, 10 and 12 results.
