What is the Grade Calculator?

The Grade Calculator has two modes. Weighted Grades adds up your assignments, tests, and categories along with their percentage weights to give you your current overall course grade and letter grade. Final Exam Needed works backward from your current grade, the final's weight, and your target grade to tell you exactly what score you need on the final.

How to Use It

In Weighted Grades, add a row for each graded item, enter its score and weight percentage (weights should total 100%), and press Calculate. In Final Exam Needed, enter your current grade, how much the final counts for, and the grade you want to end up with — the tool tells you the required score and whether it's realistically achievable.

When to Use It

Use it mid-semester to check where you stand once you know a few grades, before a final exam to figure out the minimum score you need, or when deciding whether extra credit or a retake is worth pursuing. It also helps when a syllabus lists category weights and you want your real-time grade rather than waiting for the instructor's gradebook to update.

Who Benefits

Students in any weighted-grading course, from high school to college, get a fast way to track their standing without manual math. It's also useful for tutors and parents helping a student plan study priorities based on which category weighs most heavily on the final grade.

Frequently Asked Questions

Weighted grade = Σ(grade × weight) ÷ Σ(weights). Example: if homework (30%) = 85, midterm (30%) = 78, final (40%) = 90: weighted average = (85×0.3) + (78×0.3) + (90×0.4) = 25.5 + 23.4 + 36 = 84.9.
Use the 'Final exam needed' feature: enter your current grade, the weight of the final exam, and your target course grade. The calculator tells you exactly what score you need. If the required score exceeds 100, it means the target grade is mathematically impossible.
In most US colleges and universities, a D (60–69%) is the minimum passing grade for credit, but many programs require a C or higher. For graduate school, B (80%) or higher is typically required to receive credit.
