About the GPA Calculator
This calculator turns a list of courses into a semester grade point average on the standard 4.0 scale. Enter each course's credit hours and letter grade, and the totals update as you type. Add the optional prior GPA and prior credit fields and the tool also reports a cumulative GPA that blends earlier coursework with the semester you just entered.
It suits students checking where they stand before finals, advisors modelling a retake, and anyone comparing scholarship requirements. Course names are labels only: they help you read the table but never affect the arithmetic, and nothing is saved between visits.
How to use the calculator
- Type a course name in the first column as a reminder of which class the row belongs to.
- Set the credit hours. New rows default to 3, and half credits such as 0.5 are accepted.
- Pick the letter grade from the dropdown. A+ and A are both worth 4.0, A- is 3.7, and the scale steps down to F at 0.0.
- Press Add course for another row, or the remove button to delete one. At least one row always stays.
- Optionally enter a prior GPA and prior credits to see the cumulative figure beside the semester result.
Worked example
Suppose four courses: 3 credits at A (4.0), 4 credits at B+ (3.3), 3 credits at B (3.0), and 2 credits at A- (3.7). Grade points are 12.0 + 13.2 + 9.0 + 7.4 = 41.6 over 12 credits, so the semester GPA is 3.47. If you already hold a 3.20 GPA across 45 credits, the cumulative figure becomes (3.20 x 45 + 41.6) / 57 = 3.26.
Limitations and privacy
The scale is unweighted: honours, AP, and IB courses receive no extra points, and percentages are not converted automatically. A+ is capped at 4.0 rather than 4.3. If you enter a prior GPA but leave prior credits at zero, the cumulative field repeats that prior GPA. Everything runs in your browser, so results vanish on reload and no transcript data leaves your device.
Frequently asked questions
Does the course name affect my GPA?
No. The name column is only a label. Only credit hours and the selected grade are used in the calculation.
Can I calculate a cumulative GPA across semesters?
Yes, one semester at a time. Enter your existing GPA and total earned credits in the prior fields, then add the current courses above.
Why is A+ not worth 4.3?
Most US institutions cap the 4.0 scale at A, so the tool treats A+ and A alike. Check your registrar's policy if yours differs.
