What this GPA calculator does

This tool figures your weighted grade point average on the standard 4.0 scale. Every course you take is worth a different number of credit hours, so a 4-credit chemistry class should count more toward your GPA than a 1-credit seminar. A simple average of your letter grades ignores that. A weighted GPA multiplies each grade's point value by its credit hours, adds those up, and divides by your total credits — giving each class its fair share of influence.

How the 4.0 scale works

Each letter grade maps to a grade-point value: A+ and A are 4.0, A- is 3.7, B+ is 3.3, B is 3.0, B- is 2.7, and so on down to F at 0.0. Your GPA is sum(grade points × credits) ÷ sum(credits). For example, an A (4.0) in a 3-credit class and a B (3.0) in a 4-credit class gives (12 + 12) ÷ 7 = 3.43. Schools vary slightly on plus/minus values, so treat the result as an estimate and confirm against your registrar's scale.

How to use it

  1. Pick the letter grade for your first course from the dropdown.
  2. Type the number of credit hours that course is worth.
  3. Click + Add course to add another row, and repeat.
  4. Remove any row with the × button; your GPA updates instantly as you go.
  5. Read your weighted GPA and total credits at the bottom.

FAQ

Is this a weighted or unweighted GPA?
It is weighted by credit hours, which is how colleges compute a cumulative GPA. It does not add extra points for honors or AP classes — that is a different high-school "weighted" system.
Does my data get uploaded anywhere?
No. Everything runs in your browser. Nothing you type is sent to a server or saved after you close the page.
How do I handle a semester GPA vs cumulative?
For a semester GPA, enter only that term's courses. For cumulative, enter every course across all terms, or enter each term's total credits and average grade.
Why does my school's GPA differ slightly?
Some schools use different plus/minus point values or cap A+ at 4.0 vs 4.3. Results here are an estimate; check your official transcript for the exact figure.
