CGPA Calculator
Calculate your Cumulative Grade Point Average on the 10-point scale used by IITs, NITs, VTU, Anna University, and most Indian universities. Includes conversion to US 4.0 GPA.
How to Use This CGPA Calculator
Enter each subject with its grade points (on a 0–10 scale) and the number of credits assigned to that subject. The calculator instantly computes your CGPA using the weighted average formula adopted by most Indian universities under the UGC and AICTE grading framework, including IITs, NITs, and VTU-affiliated colleges.
Use the Calculate CGPA tab to get your CGPA from individual subject grades. Switch to the Convert to US GPA tab to see how your CGPA translates to the 4.0 scale used by US universities — useful when applying abroad or submitting transcripts to credential evaluation agencies like WES or ECE.
CGPA Formula
Example: Subject A (8 GP × 4 credits) + Subject B (7 GP × 3 credits)
= (32 + 21) ÷ (4 + 3) = 53 ÷ 7 = 7.57 CGPA
CGPA is a weighted average of grade points across all subjects, where each subject's contribution is weighted by its credit load. A 4-credit subject has twice the influence on your CGPA as a 2-credit subject. This is why lab courses and electives with fewer credits have less impact on your overall CGPA.
CGPA to US GPA Conversion Formula
US GPA is capped at 4.0
Example: CGPA 8.0 → (8.0 − 0.5) × 10 ÷ 25 = 75 ÷ 25 = 3.00 US GPA
Example: CGPA 9.5 → (9.5 − 0.5) × 10 ÷ 25 = 90 ÷ 25 = 3.60 US GPA
This formula is one widely referenced approximation. The World Education Services (WES) and Educational Credential Evaluators (ECE) use their own internal scales which may differ. When submitting applications to US graduate programs, always clarify the conversion methodology with the receiving institution.
CGPA Grading Scale (India)
O (Outstanding): 9.0–10.0 | A+ (Excellent): 8.0–8.9
A (Very Good): 7.0–7.9 | B+ (Good): 6.0–6.9
B (Above Average): 5.5–5.9 | C (Average): 5.0–5.4
P (Pass): 4.0–4.9 | F (Fail): Below 4.0
Note: individual universities may use slightly different cutoffs. IITs, for example, often define their own grading scales with letter grades like AA (10), AB (9), BB (8), BC (7), CC (6), CD (5), DD (4), and F (0).
Step-by-Step Example
Scenario: Priya is a third-year B.Tech student at an NIT with these semester results:
Mathematics III (4 credits, grade 8) → 32 points
Thermodynamics (4 credits, grade 7) → 28 points
Fluid Mechanics (3 credits, grade 9) → 27 points
Engineering Materials (3 credits, grade 6) → 18 points
Machine Drawing Lab (2 credits, grade 8) → 16 points
Total: 121 points ÷ 16 credits = CGPA: 7.56
US GPA equivalent: (7.56 − 0.5) × 10 ÷ 25 = 2.82
