Calculate a weighted course grade, total a points-based gradebook, or find the score needed on a final exam. Add or remove assignments as needed and choose whether to show a common US letter grade.

Weighted grade calculation

For weighted grades, each assignment percentage is multiplied by its weight. The calculator reports the normalized average across the entered rows and the number of course percentage points earned so far. A note identifies whether the entered weights total exactly 100%.

Points-based grades

Points mode divides total points earned by total points possible. Extra credit is supported, so earned points may be greater than the possible points for an assignment.

Final grade needed

The required final exam score is calculated from the current grade, target course grade, and final exam weight. Results above 100% or below 0% are kept visible so you can tell when a target requires extra credit or has already been secured.

Letter grade boundaries vary between schools and courses. The included scales are optional display helpers; use the percentage result and your syllabus when a different grading policy applies.

Grade Calculator FAQ

What happens if assignment weights do not total 100%?

The weighted average is normalized across the weights you entered, and Entered weight shows their total. A total below 100% can represent completed work; a total above 100% usually means the weights should be checked.

Does the calculator support extra credit?

Yes. In Points mode, points earned may be greater than points possible, so extra-credit work can raise the percentage above 100%.

What does a required final grade above 100% or below 0% mean?

A required score above 100% means the target cannot be reached without extra credit under the entered assumptions. A result at or below 0% means the target is already secured even with no additional points on the final.

Do the letter grades match every school?

No. The included scales are optional display guides. Grade boundaries vary by school, course, and instructor, so use the percentage result and the scale in your syllabus when they differ.
