Add each course's credit units and grade. Your GPA updates as you go. To get your CGPA, add your earlier semesters under the courses.

Universities can apply their own rules, for example a Senate review near a class boundary. Check yours.

How GPA and CGPA are calculated

GPA = Σ (grade points × credit units) ÷ Σ credit units. The result is rounded to two decimal places. For CGPA, include the quality points and units from your earlier semesters.

Frequently asked questions

How is GPA calculated?

Multiply each course's grade points by its credit units, add those up, and divide by the total credit units. On the 5.0 scale an A is 5, B is 4, C is 3, D is 2, E is 1 and F is 0. Failed courses still count in the total units.

What is the difference between GPA and CGPA?

GPA covers one semester. CGPA, the cumulative grade point average, covers all your semesters so far. To get it, add up the quality points from every semester and divide by every credit unit taken.

How do I add my earlier results?

Open "Include earlier semesters", then enter your previous CGPA and the total credit units it covers. The calculator weights them by units and combines them with the courses you entered.

What CGPA do I need for a First Class?

On the commonly used 5.0 scale, a First Class is a CGPA from 4.50 to 5.00. Second Class Upper is 3.50 to 4.49, Second Class Lower is 2.40 to 3.49, Third Class is 1.50 to 2.39 and a Pass is 1.00 to 1.49. Universities can apply their own rules, so check with yours.

Why is there no degree class for the 4.0 scale?

Some universities use a 4.0 scale, but the class bands differ between them and we have no reliable source for a single set. The calculator gives your GPA and CGPA on the 4.0 scale and leaves the class to your university.

Does this site store my grades?

No. The calculation runs in your browser and nothing you enter is sent or saved.
