How GPA is calculated
On the 4.0 scale each letter grade is worth grade points. Multiply the grade points by the course credits to get quality points, add them up, and divide by the total credits:
GPA = Σ (grade points × credits) ÷ Σ credits
For a cumulative GPA, add your earlier quality points (previous GPA × previous credits) to the new ones and divide by all credits taken. Fill in the optional previous-record boxes and the calculator does this for you.
Grade points on the 4.0 scale
| Grade | Points | Grade | Points |
|---|---|---|---|
| A+ / A | 4.0 | C | 2.0 |
| A− | 3.7 | C− | 1.7 |
| B+ | 3.3 | D+ | 1.3 |
| B | 3.0 | D | 1.0 |
| B− | 2.7 | D− | 0.7 |
| C+ | 2.3 | F | 0.0 |
This is the common US-style scale. Some schools give an A+ 4.3 or use a different table, so check yours before relying on the result.
Worked example
| Course | Grade | Credits | Quality points |
|---|---|---|---|
| Course 1 | A (4.0) | 3 | 12.0 |
| Course 2 | B+ (3.3) | 4 | 13.2 |
| Course 3 | A− (3.7) | 3 | 11.1 |
| Course 4 | B (3.0) | 3 | 9.0 |
| Total | 13 | 45.3 |
Semester GPA = 45.3 ÷ 13 = 3.48. If your previous record was a 3.20 GPA over 30 credits (96.0 quality points), your cumulative GPA becomes (96.0 + 45.3) ÷ 43 = 3.29.

Frequently asked questions
How do I calculate GPA on the 4.0 scale?
Convert each letter grade to grade points, multiply by the course credits to get quality points, add the quality points, and divide by the total credits.
How do I calculate my cumulative GPA?
Add your previous quality points (previous GPA × previous credits) to the new quality points, then divide by the combined credits. Enter your previous GPA and credits in the calculator to do this automatically.
What is the difference between GPA and CGPA?
GPA is usually the average for a term or a whole programme on a 4.0 scale, while CGPA in India is the cumulative average on a 10-point scale. For the 10-point system use our CGPA calculator.
Do all schools use the same grade points?
No. This calculator uses the common 4.0 scale where A is 4.0 and A− is 3.7. Some schools give A+ 4.3, use plus and minus differently or have their own scale, so confirm with your institution.
Is the result from this GPA calculator official?
No. It is an estimate. Your institution or a credential evaluator decides the GPA that appears on your transcript or application.
