A grade point average (GPA) sums up your grades in a single number. It's used in the US, Canada and many other countries, and by some UK universities alongside degree classifications. Our GPA Calculator works it out.
How to use the calculator (GPA Calculator)
- List each course as its name, letter grade and credits, separated by semicolons. For example: Maths A 4; English B+ 3.
- To see your cumulative GPA, add your current GPA and credits so far.
The 4.0 scale
| Grade | Points | Grade | Points |
|---|---|---|---|
| A+ or 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 |
How GPA is worked out
Multiply each grade's points by the course's credits, add them up, then divide by the total credits:
GPA = Σ (points × credits) ÷ Σ credits
A worked example
With the calculator's default settings, five courses worth 16 credits earn 57 quality points, giving a GPA of 3.56.
