Calculate Grade
Grade Breakdown
What is a Weighted Grade?
In a standard class, every assignment is worth the same amount. You can simply add up your scores and divide by the number of assignments (which is a simple mathematical mean). If your syllabus is structured this way, use our Average Percentage Calculator instead.
However, in a weighted class, certain categories impact your final grade significantly more than others. For example, your nightly homework might only be worth 10% of your total grade, while your final exam is worth 40%. A weighted grade calculator accurately accounts for these proportions to tell you exactly where you stand in the class.
New Advanced Features!
We upgraded this tool based on student feedback to save you even more time:
- Point-Based Inputs: You no longer have to convert raw scores to percentages first. You can type fractions directly into the grade box (e.g., 45/50), and the calculator will automatically process it as 90%.
- Built-in Target Goal Seeker: Enter your desired target grade at the bottom, and the calculator will automatically figure out exactly what percentage you need to score on the remaining unassigned weight of the syllabus to achieve it!
How to Calculate a Weighted Grade Manually
Formula: (Grade₁ × Weight₁) + (Grade₂ × Weight₂) ÷ Total Weight
To calculate a weighted grade by hand, you must first convert all of the category weights into decimals (e.g., 20% becomes 0.20). Multiply each individual grade by its respective decimal weight. Finally, add all of those resulting numbers together.
Step-by-Step Example:
Homework: You scored 90%, and it's worth 20% of the class. (90 × 0.20 = 18)
Midterm: You scored 80%, and it's worth 30% of the class. (80 × 0.30 = 24)
Final Exam: You scored 85%, and it's worth 50% of the class. (85 × 0.50 = 42.5)
Total Grade: 18 + 24 + 42.5 = 84.5% (B)

The "Borderline" Grade: Will an 89.5% Round Up?
One of the most frequently asked questions at the end of every semester is whether an 89.5% or 89.9% will automatically round up to an A (90%). Here is the reality of college and high school grading policies.
🧮 The Syllabus Rule
There is no universal mathematical law that forces a teacher to round up. Your teacher's syllabus is a binding contract. If the syllabus explicitly states "A = 90.0% to 100%", then an 89.9% is technically a B+.
🎓 The "Significant Figures" Argument
In science and math classes, students often argue using significant figures. If assignments are graded in whole numbers, the final grade shouldn't be calculated to two decimal places. An 89.5 mathematically rounds to 90.
Pro Strategy: If you are sitting at an 89.4% before the final, use our Required Marks Calculator to see exactly what you need to hit a pure 90.0% so you don't have to rely on the teacher's mercy!
Frequently Asked Questions
1. What happens if my total weight isn't 100% yet?
It is perfectly normal for your current weights to add up to less than 100% if the semester isn't over yet. Our calculator automatically scales your entered assignments to give you your current standing. For example, if you've only completed assignments making up 60% of the syllabus, the tool calculates your grade solely based on that 60%.
2. How do I figure out what I need on the Final Exam?
Just use the "Target Class Grade" input box right below the calculator! If you also need to calculate your overall academic standing across multiple semesters, try our CGPA to Percentage Calculator.
3. Can I use points instead of percentages?
Yes. The tool now supports fractional inputs! If your syllabus uses a point system (e.g., you scored 45 out of 50 possible points on a project), simply type 45/50 directly into the Grade box, and the system will automatically parse it as 90%.
