When to use this calculator
Courses with more credits have more influence. Enter matching grade-point and credit lists instead of averaging course grades without weighting. Institutional exclusions and repeat policies must be applied separately.

Convert grades with your institution’s official scale
A letter grade or percentage does not map to the same grade points everywhere. First obtain the official points for each course, then enter matching credits and points in order. Courses excluded from GPA, repeat policies and pass/fail modules need the institution’s own treatment.
PUTTING IT INTO PRACTICE
GPA: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Grade points, in course order | 4,3,2 |
| Course credits, in the same order | 3,3,3 |
| Result | 3 grade points |
- Check the input labels and enter the example values above.
- Apply the relationship: GPA = sum(grade points × credits)/sum(credits).
- The result is 3 grade points, rounded for display.
How to interpret your result
Accepts up to 1,000 courses with matching lists. Use your institution’s grade-point scale and positive credit amounts. Exclude courses or apply repeat rules before entering data. This tool does not convert percentages or letter grades.
Use the grade scale and credit rules supplied by your institution. A required exam grade above the available maximum signals an unattainable target under the entered assumptions. Repeated-course and extra-credit rules need separate handling.
Frequently asked questions
Is an unweighted average the same as GPA?
Only if all included courses have equal credits. A course carrying twice the credits contributes twice as much to the weighted average.
Can this convert every institution’s grades automatically?
No. Grading scales and policies differ. Enter the grade points, weights and included credits that match your institution.
When is the gpa calculator useful?
Courses with more credits have more influence. Enter matching grade-point and credit lists instead of averaging course grades without weighting. Institutional exclusions and repeat policies must be applied separately.
How do I use the gpa calculator?
Enter grade points, in course order, course credits, in the same order. The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
GPA = sum(grade points × credits)/sum(credits).
What should I check before using the result?
Accepts up to 1,000 courses with matching lists. Use your institution’s grade-point scale and positive credit amounts. Exclude courses or apply repeat rules before entering data. This tool does not convert percentages or letter grades.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
