How weighted GPA is calculated

Grade point average on the 4.0 scale is a weighted average of your grades, where courses worth more credits count for more. This calculator multiplies each course's grade points by its credit hours to get quality points, adds those across all your courses, then divides by the total number of credits.

Because it is weighted, a strong grade in a four-credit course moves your GPA more than the same grade in a one-credit course. You can add or remove course rows to match your exact transcript, and the average updates as you go.

How to use the GPA calculator

  1. Enter each course with its credit hours and pick the letter grade from the dropdown.
  2. Use add course to include every class and remove to delete any you do not need.
  3. Read your weighted GPA, total credits and total grade points at the top of the results.

Worked examples

Three courses with mixed grades

Inputs: A 3-credit A at 4.0, a 4-credit A- at 3.7 and a 3-credit B at 3.0.

Result: Total grade points of 35.8 over 10 credits, giving a weighted GPA of 3.58.

Why credits matter

Inputs: Swapping the A onto the 4-credit course instead of the A-.

Result: The GPA rises because the higher grade now carries more credit weight, which is the whole point of a weighted average.

Limitations and common mistakes

Edge cases and limitations

  • It uses the common plus and minus 4.0 scale shown in the dropdown. Schools that weight honours or AP courses differently will not match exactly.
  • Credits accept half values, so enter your institution's actual credit hours rather than rounding.
  • It calculates a single term or cumulative figure from the rows you enter and does not store past semesters automatically.

Common mistakes

  • Entering all courses as one credit each, which turns the weighted average into a simple average and changes the result.
  • Picking the wrong grade band, since the gap between a B and a B- of 0.3 points can move a borderline GPA.

Frequently asked questions

How is GPA calculated?

Multiply each course's grade points by its number of credits to get quality points, add those up across all courses, then divide by the total number of credits. Heavier courses count more, which is why it is called a weighted average.

What grade points are used on a 4.0 scale?

An A is 4.0, A- is 3.7, B+ is 3.3, B is 3.0 and so on down to F at 0.0. Schools vary slightly, but this calculator uses the common plus and minus scale shown in the grade dropdown.

What counts as a good GPA?

On a 4.0 scale, 3.5 and above is usually considered strong, 3.0 is solid, and many programmes set a minimum of 2.0 to remain in good standing. Requirements differ by school and course, so check your own guidelines.
