How do I calculate my GPA?
Multiply each course’s grade points by its credits, add the results, and divide by the total credits. An A (4.0) in a 3-credit course, a B+ (3.3) in a 4-credit course and a C (2.0) in a 2-credit course give 29.2 quality points over 9 credits, a GPA of 3.24. Grading scales vary by institution.
- Choose letter grades on the 4.0 scale, or grade points if your institution uses another scale, such as 5 or 10.
- For each course, enter the credits and the grade. Add rows as needed; empty rows are ignored.
- Read your GPA with the total credits and quality points. For a CGPA, enter each term’s GPA and credits instead of courses.
Formulas & Methods
Quality points for a course
Example: B+ (3.3) × 4 credits = 13.2
GPA
Example: (12 + 13.2 + 4) ÷ 9 = 3.24
CGPA
Example: (3.5 × 18 + 3.8 × 17 + 3.2 × 16) ÷ 51 = 3.51
Key features
Letter grades or grade points
Use the 4.0 letter table, or type grade points on your own scale and set its maximum, so nothing is forced onto one country’s system.
GPA and CGPA
The same credit-weighted calculation works for courses in a term or for terms across a degree.

The 4.0 letter-grade table used here
Letter grades use a widely used US table. Some schools give A+ 4.33, leave out minus grades or round differently, and many countries use other scales entirely, such as 5-point or 10-point systems. If your institution publishes its own conversion, choose “Grade points” and enter its values.
- A+ and A: 4.0
- A−: 3.7 · B+: 3.3 · B: 3.0 · B−: 2.7
- C+: 2.3 · C: 2.0 · C−: 1.7
- D+: 1.3 · D: 1.0 · D−: 0.7 · F: 0
Frequently Asked Questions
Do pass/fail courses count towards a GPA?
Usually not: a pass carries credits but no grade points. Leave such courses out, unless your institution’s rules say otherwise.
Can I convert a GPA to a percentage?
Only with your institution’s own formula. Conversions such as multiplying a 10-point CGPA by 9.5 are rules set by specific boards and universities, not general maths, so check the one that applies to you.
Why is my official GPA slightly different?
Institutions may round each course, truncate rather than round the final figure, weight honours courses or exclude repeated courses. This calculator rounds only the displayed result to two decimals.
