Converts letter grades to grade points, multiplies by credit hours, and computes semester or cumulative GPA on a standard 4.0 scale.
Limitations
Schools may use different scales (e.g. weighted GPA, plus/minus variations). Confirm your institution's policy.
How to Calculate GPA
Calculate semester GPA or cumulative GPA from course credits, letter grades, prior credits, and previous GPA.
Method used
The calculator multiplies each course's credit hours by the selected letter-grade points, adds the quality points, and divides by total credits.
GPA = total quality points / total credits
Practical example
A student with 4 credits of A, 3 credits of B+, and 3 credits of A- can combine credits and grade points to estimate semester GPA.
- Course credits
- Letter grade for each course
- Optional previous credits and GPA for cumulative mode
The result shows semester GPA or cumulative GPA, total credits, and quality points.
Assumptions
- Letter grades use the calculator's standard 4.0 grade-point table.
- Credits are counted as attempted credits.
- Cumulative mode combines previous GPA data with current courses.
What this includes
- Semester GPA, cumulative GPA, editable courses, credits, letter grades, and quality points.
What this excludes
- Pass/fail courses, repeated-course replacement rules, weighted high-school GPA, school-specific policies, and transcript validation.

Frequently Asked Questions
How do I calculate GPA?
Multiply each course's credit hours by its grade points, add the quality points, then divide by total credits attempted.
Can this calculate cumulative GPA?
Yes. Switch to cumulative GPA mode, enter previous credits and previous GPA, then add the current courses.
Does this support every school's grading scale?
No. It uses a standard 4.0 letter-grade scale. School-specific plus/minus rules, pass/fail courses, and repeated-course policies may differ.
What is a quality point?
A quality point is credit hours multiplied by grade points for a course. For example, 3 credits of B (3.0 points) equals 9 quality points. Semester GPA is total quality points divided by total credits attempted.
How do plus and minus grades affect GPA?
This calculator uses a standard table where A is 4.0, A- is 3.7, B+ is 3.3, B is 3.0, and so on. Some schools round differently or omit plus/minus grades, so compare your syllabus before relying on the result for academic decisions.
