GPA Calculator
Work out a GPA as the credit weighted mean of the grade points you enter, on your own scale.
Worked example
A 3 credit course with 3.7 grade points and a 4 credit course with 3.0 grade points give 3.7 × 3 = 11.1 and 3.0 × 4 = 12. The total is 23.1 across 7 credits, and 23.1 ÷ 7 = 3.3.
How we calculated this
The GPA is the sum of each course's grade points multiplied by its credits, divided by the total credits. A course with more credits therefore counts for more.
This calculator does not have a scale of its own. It uses the grade points you enter, so the answer is on the same scale. If your top grade is worth 4.0, the GPA is out of 4.0. If your scale tops out at 5 or 10, so does the result. Enter grade points, not percentages or letters, and use the values your own school or university publishes.
Credits must be above 0, and grade points can be 0 or more. Institutions differ in how they count credits, repeated courses and pass or fail results, and many round a GPA to two decimal places. This calculator makes no claim about how yours does it, and it does not convert grades between systems.
A result written as a plain number is exact. A result starting with “≈” has been rounded to 10 significant figures, because its exact decimal never ends or is too long to read comfortably. When an exact value is long, its full digits are shown underneath. The calculation itself is never rounded: only the display is.
What this result means
The result is the credit weighted mean of the grade points you entered, on the same scale as those grade points.
Common mistakes
- Entering percentages or letters instead of grade points. Use the grade point values your own school or university publishes.
Assumptions and limitations
- It covers the courses you enter and nothing else. To work out a cumulative GPA, add courses from earlier terms as extra rows.
