GPA / CGPA Calculator
Calculate SGPA, combine semesters into CGPA, and estimate percentage.
Enter credits and grade points on whatever scale your institution uses (commonly 10-point or 4-point).
Frequently asked questions
The SGPA and CGPA math here (credit-weighted average of grade points) is the standard formula almost every university uses. What differs between universities is the grade-point scale itself and how failing grades or backlogs are handled — always cross-check against your own institution's official rules for anything that affects your transcript.
No. There's no single universal formula — different universities and boards use different multipliers (×9.5 is the most commonly cited approximation, but some use ×10 or their own certified formula). CBSE itself used a ×9.5 formula for Class 10 only from 2011-2018 and has given direct percentages since; it does not apply to current CBSE results. Treat this as a rough estimate and check your institution's official conversion for anything that matters.
Enter grade points on whatever scale your institution uses — commonly 10-point or 4-point. The calculator doesn't assume a scale; it just computes a credit-weighted average of whatever numbers you enter.
No. Every calculation happens entirely in your browser.

Gpa Calculator
Calculate SGPA from subject credits and grade points, combine semesters into an overall CGPA, and estimate percentage.
Most university and college results report a grade point average rather than a direct percentage, and combining several semesters into one overall CGPA by hand is easy to get wrong. This calculator does the standard credit-weighted average for both: enter each subject's credit and grade point to get that semester's SGPA, then enter each semester's SGPA and credit total to get the overall CGPA. A third tab gives a rough CGPA-to-percentage estimate, clearly marked as an approximation since there's no single formula every institution uses.
How to use this tool
- Use the SGPA tab: enter each subject's credits and grade point for one semester.
- Use the CGPA tab: enter each semester's SGPA and total credits to combine them.
- Use the CGPA to % tab for a rough percentage estimate.
Why users choose this tool
- Focused workflow for checking a semester result, tracking overall CGPA across semesters, or getting a rough percentage estimate.
- Helps meet assignment formatting and length limits.
- Improves writing awareness with instant metrics.
- Supports faster editing and revision cycles.
- Reliable SGPA, CGPA, and an estimated percentage generation with fewer manual steps.
Common use cases
- Check a semester's SGPA from subject-wise credits and grade points.
- Track overall CGPA across multiple semesters.
- Get a rough percentage estimate from a CGPA for a form that asks for one.
When to choose this tool
Gpa Calculator is usually faster than manual student workflows because it reduces repetitive steps and keeps the complete flow in one interface. Compared with heavyweight desktop software, this tool prioritizes speed, accessibility, and simpler controls so users can finish routine tasks quickly without installation or licensing friction. For users who mainly need checking a semester result, tracking overall CGPA across semesters, or getting a rough percentage estimate, this focused approach often gives better execution speed and cleaner day-to-day usability, while still producing SGPA, CGPA, and an estimated percentage that is suitable for practical work.
