Grade Calculator explained clearly
Quick answer: Use the Grade Calculator to combine assessment scores with their course weights. It is useful when essays, exams, projects, and quizzes each count for different parts of the final mark.
Examples are rounded where needed, so final values may differ slightly from payroll, school, or accounting systems.
Use the result as a decision aid, then confirm important school, work, or payroll decisions with the official source.
Common mistakes to avoid
- Adding scores without weights
- Using raw marks in one field and percentages in another
- Forgetting that missing assessments mean part of the course is still ungraded
Methodology
The calculator multiplies each score by its assessment weight, adds the weighted points, and shows how much of the course has been entered. Invalid scores or weights outside 0–100 are rejected.

FAQ
Do the weights need to add up to 100?
For a full course grade, yes. If not all assessments are graded yet, the calculator still shows the entered weight so you know how much of the course is covered.
Can I use decimals?
Yes. Decimal percentages are useful for detailed marking schemes.
