How to use the online CGPA calculator

  1. Choose your scale

    Select the maximum grade-point scale used by your school or university.

  2. Enter each course

    Add the grade point and credit hours for every course that should count.

  3. Review the result

    Check the weighted CGPA and breakdown, then copy or download the report.

How is weighted CGPA calculated?

Weighted CGPA is the sum of each grade point multiplied by its course credits, divided by the total included credits. A higher-credit course therefore has more influence than a lower-credit course.

CGPA = Σ (grade point × credit hours) ÷ Σ credit hours

The selected scale only sets the valid maximum grade point. It does not convert grades between different institutional systems.

Worked CGPA calculation example

On a 4.0 scale, three courses with different credit values produce this weighted calculation:

Example course quality-point calculation
Course Grade point Credits Quality points
Mathematics 3.70 3 11.10
Physics 3.30 4 13.20
English 4.00 2 8.00
Totals 9 32.30

Weighted CGPA: 32.30 ÷ 9 = 3.588…, displayed as 3.59 out of 4.00 .

CGPA calculator FAQs

How does this calculator calculate CGPA?

It multiplies every valid course grade point by its credit hours, adds the resulting quality points, and divides by the total included credits.

What is the difference between GPA and CGPA?

GPA often describes one term, while CGPA usually combines multiple terms. Institutions may define these terms differently.

Can I enter letter grades?

No. Enter the numeric grade point assigned to each letter grade by your institution so the calculation follows the correct local scale.

Can CGPA be converted directly to a percentage?

There is no universal conversion. Use only the conversion formula published by the relevant institution or awarding body.

Can I use decimal credit hours?

Yes. Positive decimal credit values are accepted for institutions that use fractional credits.

Does Tool Radar 360 store my course data?
