Semester Grade Calculator
The Semester Grade Calculator computes semester grade from the relation semester grade = sum of (component grade x weight) / sum of weights. It takes 6 inputs (component 1 grade in percent, component 1 weight in percent, component 2 grade in percent, component 2 weight in percent, component 3 grade in percent, component 3 weight in percent) and returns the semester grade. Students, parents and teachers use these calculators to see where a mark or attendance record currently stands and, where a target matters, what still needs to be achieved, whether that is planning a study workload, deciding which assessment to prioritise, or preparing for a progress meeting. Enter your values below and the result updates instantly, and you can share a permalink that pre-fills the exact calculation. Grading scales, credit weightings and attendance rules vary by school, district and country, so enter the scale, weights or threshold your own institution actually uses, keep every entry on that same scale rather than mixing points with percentages, and include only the assessments or sessions already recorded so a partial term is not read as a final result. For example, with component 1 grade = 88 percent, component 1 weight = 50 percent, component 2 grade = 92 percent, component 2 weight = 50 percent, component 3 grade = 0 percent, component 3 weight = 0 percent, the semester grade works out to 90, and the worked example further down the page shows every step so you can follow the arithmetic and reproduce it by hand. The method is the standard form documented by CalculatorHub methodology, and the figure above each result carries the date it was last verified. The output is an arithmetic result from the figures you supply and not an official academic record: your institution's own policy on rounding, dropped or replaced scores, credit values and excused absences governs the mark or attendance figure that is formally reported, so treat this as a working estimate rather than the final entry on a transcript.
With Component 1 grade = 88 percent, Component 1 weight = 50 percent, Component 2 grade = 92 percent, Component 2 weight = 50 percent, Component 3 grade = 0 percent, Component 3 weight = 0 percent, the result is 90.

The formula
semester grade = sum of (component grade x weight) / sum of weights
Worked example
With Component 1 grade = 88 percent, Component 1 weight = 50 percent, Component 2 grade = 92 percent, Component 2 weight = 50 percent, Component 3 grade = 0 percent, Component 3 weight = 0 percent:
- Weighted sum = 88x50 + 92x50 + 0x0 = 9000
- Total weight = 100
- Semester grade = 9000 / 100 = 90
- Semester Grade = 90
This worked example is one of the automated golden-value tests this calculator must pass before it can publish.
What this assumes
- Inputs are real numbers in the units shown.
- The result is the exact value of semester grade = sum of (component grade x weight) / sum of weights; general information, not professional advice.
Frequently asked questions
What formula does this use?
semester grade = sum of (component grade x weight) / sum of weights, the standard form documented by CalculatorHub methodology.
Does the result ever change over time?
No. This is a pure formula with no external rate, so the same inputs always give the same result.
