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

CGPA = Σ(Grade Points × Credit Hours) ÷ Total Credit Hours

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 = (CGPA − 0.5) × 10 ÷ 25
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

Frequently Asked Questions

SGPA (Semester Grade Point Average) is calculated for a single semester only. CGPA (Cumulative Grade Point Average) is calculated across all semesters completed so far. Your CGPA is typically a weighted average of all your SGPAs, weighted by the number of credits in each semester. Use the SGPA Calculator to compute individual semester GPAs, then use this CGPA calculator for your overall academic performance.
Most top Indian IT companies and PSUs set a CGPA cutoff between 6.0 and 7.5. Companies like TCS, Infosys, and Wipro typically require a minimum CGPA of 6.0–6.5. Premium companies like Google, Microsoft, and Goldman Sachs recruiting from IITs and NITs generally look at students in the 8.0+ range. A CGPA of 7.5 puts you in a competitive position for most campus placements at tier-1 and tier-2 engineering colleges.
The most common formula used in India is: Percentage = CGPA × 9.5 (recommended by CBSE for school boards). For engineering colleges, VTU uses CGPA × 10 − 7.5, while Mumbai University uses a different multiplier. Use our dedicated CGPA to Percentage Calculator to get results for your specific university system, since the formula varies by institution.
Yes. When you clear a backlog subject, the new grade typically replaces the previous fail grade in the CGPA calculation at most Indian universities. However, some universities record both attempts and use the better grade, while others average both. The presence of a back paper itself (even if cleared) may affect job eligibility at certain companies that have "no arrears" policies at the time of joining.
US graduate programs that receive Indian transcripts are generally familiar with the 10-point CGPA scale. Many universities either convert internally or ask for a credential evaluation from agencies like WES (World Education Services). The formula used in this calculator is an approximation — the official evaluation may differ. A CGPA of 8.0+ on a 10-point scale is typically considered equivalent to a 3.0 or above on the US 4.0 scale, which is the common graduate school floor.
