Frequently asked questions

Common questions about the GPA Calculator.

What is the difference between SGPA and CGPA?

SGPA is your grade-point average for a single semester, while CGPA is the cumulative average across all semesters. This tool gives you the SGPA per term and the overall CGPA together.

Which grading scales are supported?

You can calculate on the 4.0, 5.0 or 10.0 scale, so it works for US-style GPAs as well as many Indian and other institutions that use a 10-point system.

How do course credits affect the result?

Grades are weighted by the credit hours of each course, so a high-credit course moves your average more than a low-credit one. That is why you enter credits alongside each grade.

How do I convert my CGPA to a percentage?

There is no universal formula — each university defines its own conversion (a common rough one multiplies a 10-point CGPA by 9.5). Always use your institution's official rule for anything formal.

Can I calculate across multiple semesters at once?

Yes. Enter grades and credits per semester to get each term's SGPA, and the tool rolls them up into your overall CGPA.
