How to Use the Grade Calculator
Whether you need a school grade calculator for high school or a college grade calculator for university courses, this gradebook calculator works for any course. Start by entering each grading category from your syllabus. Type the category name (such as Homework, Quizzes, or Final Exam), set the weight as a percentage of your final grade, and enter your current score. The calculator loads three default categories to get you started, but you can add or remove categories to match your specific course.
Your overall grade updates instantly as you type — no button needed. Use it to check your grades at any point during the semester. The weight bar at the top turns green when your weights total exactly 100%, yellow when under, and red when over. If your weights do not add to 100%, the calculator still works by proportionally scaling the entered weights. To see what you need on your final exam, use our final grade calculator after finding your current standing here.
How to Calculate Your Course Grade
Multiply each category score by its weight, then divide by the sum of all weights. Here is a worked example:
• Homework (20% weight): 92%
• Midterm (30% weight): 78%
• Final Exam (50% weight): 85%
Weighted Grade = (92 × 0.20) + (78 × 0.30) + (85 × 0.50) = 18.4 + 23.4 + 42.5 = 84.3%
Sarah’s overall grade is 84.3%, which is a B.
If your course uses a points-based system instead of weights, try our test grade calculator for quick score grading. Calculate your GPA across all courses with our GPA calculator, or for courses with complex weighting, use the weighted grade calculator.
What to Do If Your Weights Don’t Add to 100%
During the semester, you may not have all categories graded yet. If you have only entered Homework (20%) and Midterm (30%), your weights total 50%. The calculator handles this by dividing the weighted sum by 50% instead of 100%, giving you an accurate current grade based on available work.
As you add more categories throughout the semester, your grade becomes increasingly accurate. Once all categories are entered and weights total 100%, the result matches exactly what your professor will calculate. Need to figure out a specific target? Our what grade do I need calculator shows exactly what score you need on upcoming assignments. You can also check where your grade falls on the grading scale guide.
