Calculate semester GPA from credits and letter grades, then combine every semester into an accurate cumulative CGPA on the 4.0 scale. Free and instant.
The GPA & CGPA Calculator works out a semester GPA from your course credits and letter grades, then lets you combine multiple semesters into an accurate cumulative CGPA on the standard 4.0 scale. Enter each course's grade and credit hours, and the calculator applies the credit-weighted average automatically rather than requiring you to work through the arithmetic by hand.
It's built for students who need to track their academic standing across a semester or an entire degree, whether checking eligibility for a scholarship, monitoring progress toward a target GPA, or simply understanding how a single course's grade will affect the overall average. The CGPA panel takes semester GPAs and credit totals to roll everything up into one cumulative figure.
Each course's grade point is multiplied by its credit hours before averaging, so a 4-credit course correctly counts more toward the overall GPA than a 1-credit elective, matching how universities actually calculate it.
Both a single semester's GPA and a full multi-semester CGPA can be calculated without switching to a separate spreadsheet or tool partway through.
Adding, editing or removing a course updates the GPA immediately, making it easy to see how a hypothetical grade change would affect the overall average before grades are finalised.
Each course's grade point value is multiplied by its credit hours, all of these are added together, and the total is divided by the sum of all credit hours. The calculator performs this automatically as courses are entered, removing the risk of an arithmetic slip when averaging several different credit weights.
GPA reflects performance in a single semester, while CGPA is the credit-weighted average across every semester completed so far. To get an accurate CGPA, enter each semester's GPA along with that semester's total credit hours into the CGPA panel, since semesters with more credits should carry proportionally more weight.
Most letter grades map onto the 4.0 scale with A as 4.0, B as 3.0, C as 2.0 and so on, though plus/minus grading can shift this slightly depending on the institution. If your school uses a non-standard scale, check its official grade-point table to make sure the values entered match its specific conversion.
Multiply each course's grade point by its credit hours, add them all up, then divide by the total credit hours. The calculator does this automatically as you type.
GPA covers a single semester, while CGPA is the credit-weighted average of every semester you have completed. Enter your semester GPAs and credits in the CGPA panel to get it.
