How to Calculate Cumulative Grade Point Average (CGPA)
The CGPA Calculator enables students across undergraduate (B.Tech, B.E., B.Sc, B.Com, BCA, BBA) and postgraduate (M.Tech, MBA, M.Sc) programs to compute their cumulative overall academic standing. It calculates credit-weighted CGPA across all semesters and provides instant bidirectional conversion between CGPA and percentage.
Step-by-Step Instructions:
- Choose Your Degree Template: Select a quick preset such as 4-Year Degree (8 Semesters), 3-Year Degree (6 Semesters), or 2-Year Degree (4 Semesters).
- Enter Semester SGPA & Credits: Input your SGPA obtained in each semester and the total credit hours registered for that semester.
- Select Your Conversion Formula: Choose your institution's official conversion formula (e.g. CBSE / Standard
CGPA × 9.5, UGC / AICTE(CGPA - 0.75) × 10, or Mumbai UniversityCGPA × 7.1 + 11). - Instant Real-Time Results: Your Cumulative CGPA, total degree credits, total accumulated grade points, and academic honors classification (Distinction, First Class, etc.) display immediately.
- Bidirectional Converter: Click the CGPA ↔ % Converter tab to quickly calculate percentage from a given CGPA or vice versa.
The Credit-Weighted CGPA Formula
When different semesters have varying credit weights, CGPA is computed as:
Cumulative CGPA Equation:
CGPA = ∑ (SGPA_i × SemesterCredits_i) / ∑ (SemesterCredits_i)
If all semesters have equal credit weights, CGPA is simply the arithmetic average of all semester SGPAs.
Common University Conversion Formulas
CBSE / Standard University
Percentage = CGPA × 9.5
Standard multiplier adopted by CBSE and central institutions.
UGC / AICTE / VTU
Percentage = (CGPA - 0.75) × 10
Used by engineering and technical university boards.
Frequently Asked Questions
How is CGPA calculated from SGPA?
Multiply each semester's SGPA by that semester's total credits, sum them up to get total grade points, and divide by the cumulative total credits of all completed semesters.
What is considered a good CGPA in college?
On a 10-point scale, a CGPA of 8.0 or above is generally considered First Class with Distinction, making students competitive for top campus placements and master's degree admissions. A CGPA of 9.0+ represents outstanding academic excellence.
How do I convert 8.5 CGPA to percentage?
Under the standard CBSE/UGC formula (multiplier 9.5), 8.5 × 9.5 = 80.75%. Under the AICTE formula (8.5 - 0.75) × 10 = 77.50%.
