How it works
Each letter maps to a point value (often A=4, B=3, etc.). The calculator sums quality points and divides by total attempted credits per your inputs.
Formula
GPA = Σ (grade points × credits) ÷ Σ credits
How to use GPA Calculator
- Add each course with letter grade and credit hours.
- Include labs and seminars with their actual credit values.
- Read semester GPA and total quality points if displayed.
- Use test or weighted grade tools for in-progress course estimates.
Worked examples
Concrete numbers and cases you can check against the tool above.
Three courses, 4 credits each
Grades A (4.0), B+ (3.3), B (3.0) with 4 credits each → (16+13.2+12)/12 = 3.43 semester GPA.
When to use GPA Calculator
Scholarships and probation rules hinge on GPA; hand spreadsheets mis-weight labs vs seminars. Enter credits once per course for an accurate weighted mean.
Common use cases
- Project GPA after hypothetical grade changes.
- Combine transfer credits with local courses for cumulative GPA.
- Check eligibility for honors or athletic requirements.
Inputs and outputs
- Letter grades mapped to 4.0 scale points
- Credit hours per course

Frequently asked questions
- Do plus/minus grades count?
- Only if the tool’s scale includes them (e.g. B+ = 3.3). Match your school’s registrar table.
- Are pass/fail courses included?
- Pass/fail usually does not affect GPA; omit them unless your policy says otherwise.
- Weighted vs unweighted GPA?
- This tool typically uses standard 4.0 unweighted points unless a weighted AP/honors mode is offered on the page.
