Combined percentage
Divides all entered earned points by all entered possible points.
Enter earned and possible points for up to five graded items to calculate your combined percentage and a reference letter grade.
Percentage grade = total earned points / total possible points x 100. This page's reference letter grade uses a common 97/93/90 scale, which may differ from a course's official scale.
Divides all entered earned points by all entered possible points.
Maps the percentage to the displayed common letter scale.
Shows the combined earned and possible points for an audit trail.
Enter the points earned and points possible for each completed item. The calculator adds the earned points, adds the possible points, then divides the two totals to produce one percentage. This point-total approach is useful only when each point has the same course value or when your instructor has already converted categories into comparable points.
A percentage and a letter grade are not always interchangeable. This page shows a common letter-grade reference scale, but many schools use different cutoffs, plus/minus policies, pass/fail marks, curves, or rounding rules. Treat the letter output as a check, then use the syllabus or official gradebook for the course rule.
Do not enter category percentages into this points calculator unless their possible-point values reflect the intended weighting. When homework, tests, labs, and a final each have separate syllabus weights, use the Weighted Grade Calculator instead. For an upcoming final target, use the Final Grade Calculator.

|---|---|---|
| Earned points | Points awarded for an item | Use the gradebook value after any instructor adjustment. |
| Possible points | Maximum regular points for the same item | Keep points and possible points in the same grading basis. |
| Percentage | Earned total divided by possible total | Official rounding may differ. |
| Letter grade | Reference category based on the displayed scale | Confirm course-specific cutoffs separately. |
