GPA / CGPA Calculator — Free Online

Multiply each subject's credit hours by its grade points, add all of those quality points together, then divide by the total credit hours. Example: (3 × 4.00) + (3 × 3.33) + (2 × 3.67) + (1 × 4.00) = 35.33 quality points ÷ 9 credit hours = 3.93 GPA. Adding up grade points without the credit weighting is the most common mistake.

Multiply your existing CGPA by the credit hours you have already completed, add this semester's quality points, then divide by the combined credit hours. Enter both figures in section 2 and the calculator shows the new CGPA with the working underneath.

The simple, widely used conversion is GPA ÷ 4 × 100, so 3.50 becomes 87.5%. Some universities in South Asia instead use a 10-point scale and divide the percentage by 9.5. Because the rules differ, always use your own institution's published conversion for official documents.

An F contributes its credit hours to the total but zero quality points, so it drags the average down — including it in this calculator shows the honest picture. When a course is repeated, most universities keep the better grade in the CGPA but still count both attempts in the transcript; follow your own university's repeat policy.

No. This tool uses the common scale where A = 4.00, A- = 3.67, B+ = 3.33, B = 3.00, B- = 2.67, C+ = 2.33, C = 2.00, C- = 1.67, D+ = 1.33, D = 1.00 and F = 0. Some institutions use B- = 2.50 or drop the D grades entirely. Check your student handbook for the official table before relying on the number for a scholarship or degree classification.
