Most university courses do not grade you on one exam. Assignments, quizzes, a mid-term, projects and a final each count for a set percentage. Knowing your weighted grade during the semester tells you exactly where you stand and how much the remaining work matters. This guide explains the method with examples, using our free Grade Calculator.
The formula
Weighted grade = Σ (score × weight) ÷ Σ weight of graded work
Scores are percentages; weights are the share each item has in the final grade.
Example course outline
| Component | Weight | Your score |
|---|---|---|
| Assignments | 15% | 88% |
| Quizzes | 10% | 75% |
| Mid-term | 25% | 70% |
| Project | 10% | not graded yet |
| Final exam | 40% | not taken yet |
Calculating your current grade
Only the graded items count so far:
- Assignments: 88 × 15 = 1,320
- Quizzes: 75 × 10 = 750
- Mid-term: 70 × 25 = 1,750
- Total: 3,820 ÷ 50 (weights so far) = 76.4%
So you are currently at 76.4% on the half of the course that has been graded.
Why weights matter
A 90% on a 10% quiz adds only 9 points to the final grade, while a 60% on a 40% final costs you a lot. Focus your effort on the heaviest components.
Points instead of percentages
If you got 18 out of 25 on an assignment, convert it first: 18 ÷ 25 × 100 = 72%. The Percentage Calculator does this quickly.
Turning the grade into a letter and GPA
Your university’s scale converts the final percentage into a letter grade and grade points. Those feed into your semester GPA; use the GPA Calculator after results.
Plan the rest of the semester
Once you know your current grade, you can work out what you need on the remaining items. Read what you need on your final exam for that calculation.
Frequently asked questions
How do I calculate a weighted grade?
Multiply each score by its weight, add them and divide by the total weight of graded items.
What if my weights do not add up to 100%?
Use only graded items for your current grade, and check the course outline for the full weights.
How do I convert points to a percentage?
Divide your points by the maximum points and multiply by 100.
