Course Grade Calculator

The course grade calculator at allgradecalculator.com follows the standard syllabus structure — homework, quizzes, midterms, projects, the final exam — each with its own weight. Rename each row to match your course, type the score and weight, and the calculator returns your overall course grade and a US letter grade. The right-hand panel also tells you the score you need on the final to hit a target.

Course grade vs single assignment

A course grade is the weighted combination of every graded item in a class. A single assignment grade is just one row of that. For one assignment, use the assignment grade calculator; to combine the whole semester, use this page.

How to use it

  1. List every category from the syllabus as a row.
  2. For each row, enter the score and maximum points.
  3. Enter the weight (%) — typically the syllabus prints these explicitly.
  4. Confirm the total weight indicator stays at 100%.
  5. Read the overall course grade and letter grade.

Tips

  • Pull weights directly from the syllabus, not from your gradebook software (the LMS sometimes rounds).
  • Use the "target final grade" panel mid-semester to plan study time.
  • Combine the result with the GPA calculator for a 4.0-scale equivalent.

Frequently asked questions

How is a course grade calculated?

Each component contributes in proportion to its weight: overall = Σ(score × weight) ÷ Σ(weight). The calculator normalises by total weight automatically, so weights don’t have to sum to exactly 100.

What if my instructor drops the lowest quiz?

Omit that row from the calculator (or reduce that quiz’s weight to zero). The result is the post-drop course grade.

How is this different from the grade calculator?

Same engine, different framing. The course grade calculator focuses on the syllabus structure of a single class. The grade calculator at /grade-calculator is a more general weighted-grade tool.
