How to use the CGPA Calculator

- Enter the SGPA and total credits for that semester.
- Click Calculate to see your CGPA out of 10 and the approximate percentage.
- Check your university's rules for the exact percentage conversion.
Formula used
The × 9.5 conversion comes from CBSE and is widely used, but many universities (for example some AICTE-affiliated colleges) use their own formula such as (CGPA − 0.75) × 10.
Worked example
Four semesters
Sem 1: 8.2 × 22 credits
Sem 2: 7.8 × 24 credits
Sem 3: 8.6 × 22 credits
Sem 4: 9.0 × 20 credits
CGPA = 8.37; percentage ≈ 8.37 × 9.5 = 79.5%
SGPA vs CGPA
SGPA (Semester Grade Point Average) measures performance in one semester. CGPA (Cumulative Grade Point Average) combines all semesters, weighted by credits. Because of the weighting, a semester with more credits pulls your CGPA more than a lighter semester.
Tips for accurate results
- Use exact credits from your marksheet, not the number of subjects.
- Simple averaging of SGPAs is only correct if every semester has the same credits.
- Many placement drives ask for CGPA rounded to two decimals.
