How it works
Enter a label and minimum score for each grade. The calculator orders valid boundaries from highest to lowest and selects the highest minimum that your score meets.

The quick guide
Make the boundaries explicit
A boundary describes the minimum score at which a grade begins.
Example
With A at 80 and B at 70, a score of 76 matches B because it reaches 70 but not 80.
Institution-neutral by design
Use the boundaries from your course
Institutions may use letters, numbers, plus/minus grades, pass bands, or other rules. The example is editable and illustrative only. Check your syllabus, transcript guidance, or official policy before relying on the result.
FAQ
What makes two boundaries invalid?
Blank labels, invalid scores, duplicate minimums, and boundaries that are not strictly ordered are rejected. Duplicate minimums would make two grades claim the same starting point.
Can I edit the example boundaries?
Yes. Use the example as a starting point, then change labels and minimum scores to match your own institution.
What if my grading system uses a different scale?
Enter the scale’s values if they can be represented as a 0–100 score. If your system uses a table or rules beyond minimum boundaries, use its official method instead.
