Semester Grade Calculator

It combines every graded item in a class into one overall percent for the semester. Points mode adds your earned points across all items, divides by total possible points, and converts to a percent. Weighted mode treats each item or category as its own percent and combines them by weight, which is what most syllabi do.

Use points mode when the syllabus says everything counts the same per point. Add up all earned and possible points and you have your grade. Use weighted mode when the syllabus assigns each category a percent of the course grade, like homework 20 percent, midterm 25 percent, final 30 percent. Weights do not have to sum to 100; the calculator normalizes them.

This calculator uses a standard scale: A is 90 to 100, B is 80 to 89.99, C is 70 to 79.99, D is 60 to 69.99, and F is below 60. Some courses use plus and minus letters; this estimate uses whole letters only. Check your syllabus for the exact cutoffs your instructor uses.

Yes. Use the Add item button to insert as many rows as you need. Empty rows or rows with zero possible points are ignored, so the result only reflects the items where you have entered numbers.

In points mode, extra credit shows up automatically: earned points can exceed possible points, which lifts the overall percent. In weighted mode, you can model extra credit by adding a small extra row with a small weight and a high percent. The result respects the relative weights you enter.
