How It Works

The calculator multiplies your assignment score by its weight and your exam score by its weight, then sums the two products: (assignmentScore × assignmentWeight) + (examScore × examWeight). This sum is divided by the total weight (assignmentWeight + examWeight) to produce your final weighted grade percentage. Dividing by the actual total weight — rather than assuming 100 — ensures the calculation works correctly even mid-semester when only some components are graded and weights do not yet sum to 100. For example, if you have only completed assignments worth 60% and an exam worth 40%, entering both gives a total weight of 100 and a standard result. If you have only completed the assignments so far (weight 60), the calculator divides by 60, correctly reflecting your standing on the portion of the course graded to date rather than penalizing you for the exam you have not yet taken.

Examples

Standard syllabus
Homework is 85% (weight 60), Exam is 92% (weight 40).
Result: Your final grade is an 87.80%.
Heavy final exam
Entering a 90% average for coursework (weight 30) and an 80% on the final exam (weight 70).
Result: The final grade pulls heavily toward the exam, landing at 83.00%.
Incomplete weighting
Weights don't equal 100 (e.g., Assignment weight 50, Exam weight 25).
Result: Calculates the proportional grade of 93.33% based only on the completed 75% of the class.

Frequently Asked Questions

Do my weights need to add up to 100%?
No. If you only input the assignments you have finished so far, the calculator will properly average your current standing based on the sum of the weights provided.
What if I have more than two categories?
This basic calculator handles two major categories. You can average all your minor categories into one 'Assignment' score, or use a more advanced multi-category calculator.
How do I know the weight of my assignments?
Check your class syllabus. Professors outline exactly how much percentage weight is assigned to homework, participation, midterms, and finals.
Is this the same as a GPA calculator?
No, a GPA calculator averages your letter grades across multiple different classes. This calculates your percentage score within a single class.
