GPA Calculator Online — Free Tool
Accurately calculate your Grade Point Average (GPA) using a standard 4.0 scale based on your course credits and letter grades.
About this tool
This GPA calculator estimates your grade point average on the common 4.0 scale used by many colleges and universities. Each course is weighted by its credit hours, so a three-credit class affects your GPA more than a one-credit lab.
Letter grades are converted to grade points (for example, A = 4.0, B = 3.0), then multiplied by credits and averaged across all courses you enter. Use it to project semester GPA, cumulative GPA, or to see how one grade change would move your average.
Common use cases
- Planning course loads before registration
- Checking whether you meet scholarship or program GPA minimums
- Comparing semester results to your cumulative average
- Seeing how retaking a course could lift your overall GPA
How to use
- Add each course with its letter grade and credit hours.
- Include all courses for the period you want to calculate—semester or cumulative.
- Review the weighted GPA result that updates as you edit entries.
- Adjust a single grade to model how it would change your average.

Understanding the result
- GPA is credit-weighted: higher-credit courses pull the average more than low-credit electives.
- A 4.0 scale maps letter grades to fixed point values; plus/minus variants may use intermediate values depending on your school.
- Semester GPA covers only the courses you entered; cumulative GPA requires every term you want included.
- Small changes in high-credit courses move GPA faster than the same letter change in a one-credit class.

FAQ
How is GPA calculated on a 4.0 scale?
Each letter grade converts to grade points, multiplied by credit hours, summed, then divided by total credits attempted.
Do pass/fail courses affect my GPA?
Pass/fail courses are usually excluded from GPA calculations. Only graded, credit-bearing courses should be entered.
Can I calculate cumulative GPA across multiple semesters?
Yes. Enter every graded course from all semesters you want included and the tool averages them by total credits.
What if my school uses a different scale?
This tool uses the standard 4.0 mapping. If your institution uses 5.0 for honors or a custom scale, treat results as an estimate.
