How to Calculate SGPA Online Free
SGPA is your Semester Grade Point Average — the weighted average of your grades for one semester, where each subject counts according to its credits. This guide shows how to calculate SGPA from your subjects, credits and grades, on a 10-point, 4.0 or custom scale, with the equivalent percentage. Use the free SGPA calculator below to work out your SGPA in seconds.
How to Calculate SGPA — step by step
- Pick your grade scale — 10-point, 4.0, or custom grade points.
- Add a row for each subject and enter its credits and grade.
- Remove any row you do not need with the × button.
- Read your SGPA: it updates live as you change anything.
Tips
- Use the 10-point scale if your university grades O to F on 10 points, and the 4.0 scale if it grades A to F on 4 points — or Custom to enter grade points directly.
- Credits weight the average: a 4-credit subject counts twice as much as a 2-credit one.
- The formula is (grade points × credits for each subject, added up) ÷ total credits — for example, 4 credits at 8 points and 2 credits at 10 points gives (32 + 20) ÷ 6 = 8.67.
Frequently asked questions
How is SGPA calculated?
Multiply each subject's grade points by its credits, add those up, then divide by the total credits. For example, 4 credits at 8 points and 2 credits at 10 points gives (32 + 20) ÷ 6 = 8.67.
What is the difference between SGPA and CGPA?
SGPA covers one semester. CGPA covers all your semesters so far, weighting each semester by its credits.
Which grade scale should I pick?
Use the 10-point scale if your university grades O to F on 10 points, and the 4.0 scale if it grades A to F on 4 points. If your university uses another scale, pick Custom and enter the grade points directly.
