What is a GPA?

A GPA / CGPA Calculator computes your Grade Point Average (GPA) or Cumulative Grade Point Average (CGPA) from your subjects' credit hours and grade points. It reflects your academic performance as a weighted average, where subjects with more credit hours have a larger impact on the final CGPA.

In India, the 10-point CGPA system under the UGC Choice Based Credit System (CBCS) is now the standard at most universities, IITs, NITs, central universities, and most state universities including Anna University (Tamil Nadu), VTU (Karnataka), JNTU (Andhra Pradesh), and Mumbai University. This calculator covers both the 10-point Indian scale and the 4-point international scale.

Along with the CGPA, the calculator converts your grade to a percentage using the official UGC formula: Percentage = (CGPA − 0.75) × 10, so you can easily translate your CGPA for job applications, competitive exam forms, and foreign university applications that ask for percentage.

See the Grade Calculator for converting raw marks to grades, and the Percentage Calculator for other percentage calculations.

Why Use a CGPA Calculator?

Manual CGPA calculation is tedious when you have 5–6 subjects with different credit weightings. Mistakes in weighting are common, many students incorrectly calculate a simple average of grade points rather than credit-weighted average, which gives a wrong result.

A student with subjects of 4, 4, 3, 3, 2 credits who grades 9, 8, 7, 8, 9 GP:

  • Simple average: (9+8+7+8+9) ÷ 5 = 8.2 (wrong)
  • Weighted average: (36+32+21+24+18) ÷ 16 = 131 ÷ 16 = 8.19 (correct)

The difference may seem small, but it matters for eligibility cutoffs.

Who Should Use This Calculator?

Engineering and science students at VTU, JNTU, Anna University, Mumbai University, and other universities using 10-point CBCS who need to track semester CGPA for placement eligibility.

Students applying for campus placements who need to verify their CGPA meets the minimum cutoff (commonly 6.0 or 7.0) at recruitment drives.

Students applying for higher education (GATE, GRE, GMAT, CAT) who need to report CGPA on application forms and verify the equivalent percentage for eligibility.

International students studying in India on a 10-point system who need to understand their GPA equivalent for home country recognition or international scholarships.

Frequently Asked Questions

What is CGPA and how is it calculated?

CGPA (Cumulative Grade Point Average) is a weighted average of grade points earned across all subjects, where each subject's grade point is weighted by its credit hours. Formula: CGPA = Total (Credits × Grade Points) ÷ Total Credits. For example, if you earned 9 GP in a 4-credit subject and 8 GP in a 3-credit subject: CGPA = (4×9 + 3×8) ÷ (4+3) = (36+24) ÷ 7 = 60 ÷ 7 = 8.57.

How do I convert CGPA to percentage for Indian universities?

The UGC (University Grants Commission) formula for 10-point CBCS scale is: Percentage = (CGPA − 0.75) × 10. So a CGPA of 8.5 = (8.5 − 0.75) × 10 = 77.5%. Some universities use their own conversion: Anna University uses CGPA × 10 − 0.5; Mumbai University uses (CGPA − 0.5) × 10; VTU uses CGPA × 10. Check your university's specific conversion formula. This calculator uses the UGC formula by default for 10-point scale.

What is the UGC-CBCS grading system?

CBCS (Choice Based Credit System) was introduced by UGC in 2015 and adopted by most central universities and many state universities across India. It uses a 10-point grading scale with letter grades: O (Outstanding) = 10 GP, A+ (Excellent) = 9 GP, A (Very Good) = 8 GP, B+ (Good) = 7 GP, B (Above Average) = 6 GP, C (Average) = 5 GP, P (Pass) = 4 GP, F (Fail) = 0 GP. Credit hours range from 1–6 per subject depending on contact hours.

What is the difference between CGPA and SGPA?

SGPA (Semester Grade Point Average) is the GPA for a single semester, calculated the same way as CGPA but only using that semester's subjects and credits. CGPA is the cumulative GPA across all semesters completed so far, it is the weighted average of all SGPAs, weighted by semester credits. On your marksheet, you will see both: SGPA for the current semester and CGPA cumulative to date. CGPA is what matters for job eligibility criteria and postgraduate admissions.

What CGPA is required for jobs and higher studies in India?

For campus placements at IT companies (TCS, Infosys, Wipro, Accenture): minimum CGPA of 6.0 on 10-point scale or 60% equivalent. For product companies (Google, Microsoft, Amazon): no stated CGPA cutoff typically, but effective minimum is around 7.5–8.0. For IIM MBA admissions (CAT): no formal CGPA cutoff, but shortlisting for PI rounds typically requires 6.5+ CGPA. For IIT/NIT M.Tech (GATE): CGPA 6.0–7.0 is typically the minimum for admission. For PSUs (UPSC, BHEL, NTPC): typically require 60% or CGPA 6.5+ on 10-point scale.

How does the 4-point GPA scale work for international universities?

The 4-point scale is used by US, UK, Canadian, and many other international universities. Letter grades map as: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, D = 1.0, F = 0. A 4-point GPA is calculated the same way as CGPA, weighted by credit hours. For converting Indian CGPA (10-point) to 4-point GPA for international applications: approximate conversion = (CGPA − 0.5) × 0.4, or use WES (World Education Services) for official evaluation.

How do I find my grade point for each subject?

Your grade point is shown on your marksheet or semester report card beside each subject. On 10-point CBCS scales, it is typically a value from 0–10. Some universities show the letter grade (O, A+, A, B+ etc.) and you convert it: O=10, A+=9, A=8, B+=7, B=6, C=5, P=4, F=0. Credits per subject (typically 2–6) are also shown on your marksheet or in the course structure document. Enter these values into the calculator for each subject.

How do I use the GPA/CGPA Calculator?

Select your grading scale (10-point for most Indian universities, 4-point for US/international). For each subject, enter the credit hours and your grade point. Set credits to 0 for Subject 6 if you have only 5 subjects. The calculator shows your CGPA/GPA, percentage equivalent (using UGC formula for 10-point scale), total credits, and total grade points. The Steps panel shows the credit × grade calculation for each subject.

Which Indian universities use the 10-point CGPA system?

Most Indian universities that follow UGC-CBCS now use the 10-point CGPA system: IITs, NITs, central universities (Delhi University, Hyderabad University, Jadavpur University), VTU (Karnataka), Anna University (Tamil Nadu), JNTU (Andhra Pradesh/Telangana), Mumbai University, Pune University, and hundreds of state universities. CBSE schools also switched to a 10-point CGPA system for Class 10 (replaced by percentage in 2017, but CGPA was used 2010–2016).

How is CGPA different from percentage?

Percentage is the absolute marks obtained as a fraction of total marks (marks obtained ÷ total marks × 100). CGPA is a normalised grade point on a fixed scale (0–10 or 0–4), computed as a credit-weighted average of grade points, not marks. Two students with 75% may have different CGPAs depending on credit distribution. CGPA is more standardised across institutions, which is why employers and universities increasingly accept it, but many older organisations still ask for percentage, hence the need for a conversion formula.

What is the minimum passing CGPA in Indian universities?

Under UGC-CBCS, the minimum passing grade point is 4.0 (P grade = Pass). A student must secure at least 4.0 GP in each subject to pass. If the CGPA falls below 4.0 due to backlog subjects (F grade), the student is not eligible to receive the degree. Most universities also require a minimum CGPA of 4.0 or 40% aggregate to pass a semester. Engineering universities (VTU, JNTU, Anna University) typically require 5.0 GP (C grade) as the minimum for passing each subject.

Can CGPA be improved after a semester?

Yes. CGPA is cumulative, each subsequent semester's results change the overall CGPA. If you scored 6.0 in Semester 1 (on 20 credits) and score 8.0 in Semester 2 (on 24 credits): CGPA = (6.0×20 + 8.0×24) ÷ (20+24) = (120 + 192) ÷ 44 = 312 ÷ 44 = 7.09. Better performance in later semesters with more credits can meaningfully improve CGPA. Backlogs (F grades) in earlier semesters pull down CGPA significantly, clearing them as early as possible is important.
