This semester grade calculator combines two term grades and a final exam using your school's exact weights, or finds the final-exam score needed for a target semester grade. The weights stay visible because semester formulas vary by school.
Copy the formula your school actually uses
A 40/40/20 split is common enough to be a useful example, but it is not a default rule. The three visible weights make the calculation auditable.
The calculator rejects incomplete or overlapping formulas instead of silently normalizing them.
Enter term and final scores as percentages, not letters, GPA points, or raw points.
Semester grade calculates an overall mark from a final score. Final score needed works backward from the overall mark you want.
Example: 86%, 92%, and 88% under 40/40/20
- The weighted contributions are
86 × 0.40 = 34.4,92 × 0.40 = 36.8, and88 × 0.20 = 17.6. - Their sum is 88.80%, which is the semester grade.
Semester grade is not semester GPA
This page returns one course percentage. A GPA combines course grades after converting them through a school-specific grade-point scale and may apply course-credit or honors weights. Use the GPA tools only after you have the course grades your school records.
Why required-final results can exceed 100%
The two completed terms may leave a gap larger than the final exam can close. When the required result is above 100%, the target is outside the range produced by a standard 0–100 final under the entered weights. The displayed outcome range makes that boundary visible.
Frequently asked questions
How does a quarter grade affect a semester grade?
Its effect equals its semester weight. A quarter worth 40% contributes 0.40 times its percentage, so one point on that quarter changes the semester result by 0.4 .
What grade do I need on the final to reach my target?
Choose Final score needed, enter both term grades and all three weights, then enter the target semester percentage. The calculator returns the exact final score required under those weights.
How do I calculate my semester grade without the final?
Use Final score needed to test a target, or use Semester grade with an expected final score. A completed semester grade cannot be known until a final score or an official policy for omitting it is available.
