Semester Grade Calculator
Combine weighted assessment components into an overall semester grade.
About Semester Grade Calculator
Normalising by the total weight entered means the result stays meaningful even when components are missing. The contribution figures show where the grade actually comes from rather than which score is highest. A high score on a lightly weighted component contributes little, so effort is best allocated by weight rather than by how much a component is worth in isolation.
Formula
Semester Grade
Overall = Σ(score × weight) ÷ Σ(weight)
- weight
- Share of the final grade each component contributes
- normalisation
- Dividing by total weight so the result holds even if weights do not sum to 100

Assumptions and limits
- The result is derived only from the 6 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Semester Grade calculated?
Overall = Σ(score × weight) ÷ Σ(weight) Normalising by the total weight entered means the result stays meaningful even when components are missing. The contribution figures show where the grade actually comes from rather than which score is highest.
Why does Semester Grade matter?
A high score on a lightly weighted component contributes little, so effort is best allocated by weight rather than by how much a component is worth in isolation.
What values do I need to enter?
This calculator takes 6 inputs: Assignment score, Assignment weight, Midterm score, Midterm weight, Final exam score, Final exam weight. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
