What is a semester grade calculator?
A semester grade calculator combines several graded periods or components when they contribute different percentages to the final semester mark. Common inputs can include quarters, trimesters, projects, midterms and final exams.
For a broader set of weighted assignment categories, use the Grade Calculator.

Why must the weights total 100%?
A complete semester grade represents the full course weighting, so all included components should account for the entire 100%. If your course is still in progress and not all components are known, use the general Grade Calculator, which can normalize a partial weight.
If only the final exam remains, the Final Grade Calculator can estimate the score needed for your target.
Semester grade formula
Each component score is multiplied by its weight as a decimal. The weighted contributions are then added. For example, an 88% quarter weighted at 40% contributes 35.2 percentage points to the semester total.
For one exam measured in earned and possible points, the Test Grade Calculator is the more direct option.
Match the school’s weighting rules
Use the percentages published in the syllabus or gradebook. Schools may average quarters first, round intermediate scores, or apply special final-exam rules, which can make the official result differ from a simple weighted calculation.
For points-based coursework without category weights, use the Percentage Grade Calculator.
Worked example: Semester Grade
Enter the following values in the Semester Grade Calculator and calculate to reproduce this result.
- Item 1: Homework
- Score % (entry 1): 92
- Weight % (entry 1): 40
- Item 2: Homework
- Score % (entry 2): 92
- Weight % (entry 2): 30
- Item 3: Homework
- Score % (entry 3): 92
- Weight % (entry 3): 30
Example result: 92%. Your weighted semester grade is 92% using components that total 100%.
Calculation used: Semester grade = Σ(component score × component weight)
How to interpret this example
Use weights of 40%, 30% and 30% for the three components in this example. With every score at 92%, the weighted sum is 36.8 + 27.6 + 27.6 = 92%. A different syllabus weighting changes mixed-score results.
