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.
How to Calculate Your Grade Using a Points-Based System
Many professors grade using total points instead of weighted categories. In a point-based system, each assignment has a set number of points, and your final grade is the percentage of total points earned. This grade calculator handles points-based grading just as easily as weighted categories.
Grade = (Total Points Earned ÷ Total Points Possible) × 100
Example: 425 earned out of 500 total = (425 ÷ 500) × 100 = 85.0% (B)
To use this calculator with a point system, convert each category to a percentage first. If you earned 85 out of 100 on a midterm, enter 85% as the score. If homework was 180 out of 200, enter 90%. Then set each category weight to reflect its share of total points — the midterm is 100 out of 500 total, so its weight is 20%. The grade calculator by points works the same way because percentages and point totals are interchangeable once you do this conversion.
• Labs (150 points, 25% weight): scored 135/150 = 90%
• Quizzes (100 points, ~17% weight): scored 82/100 = 82%
• Midterm (150 points, 25% weight): scored 123/150 = 82%
• Final (200 points, ~33% weight): scored 172/200 = 86%
Jake enters these four categories with their percentages and weights. His overall grade: 85.5% (B).
Using This Grade Calculator for College Classes
College courses typically break grades into 4-6 weighted categories listed in the syllabus: participation, homework, quizzes, a midterm exam, and a final exam. This college grade calculator matches that structure exactly. Enter each category from your syllabus, set the weight, and type your current score to see your standing in the course.
Most college courses weight the final exam between 25% and 40% of the total grade, which means one exam can swing your letter grade by a full level. Use the what-if scenarios above to see what final exam score you need to hit your target. If you need your GPA across multiple college classes rather than a grade in a single class, use our college GPA calculator instead.
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.
