Weighted Grade Calculation by points
Step-by-Step Method: Ensure Curve +points and Curve +percent are set to 0.
- List each category and its weight
Example:- Assignments→ 20%
- Quizzes → 30%
- Exams → 50%
- For each category, find your total points earned and total points possible
Example:- Assignments → 180 / 200
- Quizzes → 135 / 150
- Exams → 400 / 500
- Find your percentage in each category
- Assignments → 180 ÷ 200 = 0.9 (or 90%)
- Quizzes → 135 ÷ 150 = 0.9 (or 90%)
- Exams → 400 ÷ 500 = 0.8 (or 80%)
- Multiply each percentage by its weight
(Make sure weights are in decimals, e.g., 20% → 0.2)- Assignments: 0.9 × 0.2 = 0.18
- Quizzes: 0.9 × 0.3 = 0.27
- Exams: 0.8 × 0.5 = 0.40
- Add them all up
→ 0.18 + 0.27 + 0.40 = 0.85 (or 85%)
Final Grade: 85%
How was this grade calculated?
Formulas
- Weighted Grade = Sum of (Points Earned ÷ Points Possible × Category Weight)
- Weighted Grade=(90%×20%)+(90%×30%)+(80%×50%)
- Assignments → 180 out of 200 (weight = 20%)
- Quizzes → 135 out of 150 (weight = 30%)
- Exams → 400 out of 500 (weight = 50%)
- Final Grade=(180/200×0.20)+(135/150×0.30)+(400/500×0.50)
- Final Grade=(0.9×0.20)+(0.9×0.30)+(0.8×0.50)
- Final Grade=0.18+0.27+0.40=0.85
Final Grade = 85%
Weighted grade calculation by percent.
Step-by-Step Method
- List your categories and weights
Example:- Homework → 20%
- Quizzes → 30%
- Final Exam → 50%
- Find your average score in each category
Example:- Homework average = 85%
- Quiz average = 90%
- Final Exam = 80%
- Convert each weight into a decimal
- Homework: 20% → 0.20
- Quizzes: 30% → 0.30
- Final Exam: 50% → 0.50
- Multiply each category average by its weight
- Homework: 85 × 0.20 = 17
- Quizzes: 90 × 0.30 = 27
- Final Exam: 80 × 0.50 = 40
- Add them up
17+27+40=8417 + 27 + 40 = 8417+27+40=84
Final Weighted Grade = 84%
How was this Calculated?
Formulas
Weighted Grade=∑Weights∑(Score×Weight)
- If weights already add up to 100%, you can skip dividing by the total weight.
Final Grade=(w1×g1)+(w2×g2)+(w3×g3)+…
- But only if the weights add up to 1 (or 100%)
(85×0.2)+(90×0.3)+(80×0.5)=17+27+40=84
- Homework = 85% × 0.2
- Quizzes = 90% × 0.3
- Final Exams = 80% × 0.5
Final Grade = 84%
Weighted grade calculation by letter A-F
Step-by-Step Guide
How to assign grade points on the grade calculator
First, understand the Letter and grade point values with the grade calculator. You can check the edit thresholds above and set your desired ones if you wish.
| Letter | Grade Points |
|---|---|
| A | 4.0 |
| B | 3.0 |
| C | 2.0 |
| D | 1.0 |
| F | 0.0 |
Some schools use plus/minus (like A– = 3.7, B+ = 3.3,
Multiply by Credit Weight
Each course or assignment has a weight, which could be in percentage or credit hours.
To get the weighted score, multiply:
Grade Points × Weight
| Course | Letter Grade | Grade Points | Weight | Weighted Points |
|---|---|---|---|---|
| Math | A | 4.0 | 40% | 1.6 |
| English | B | 3.0 | 30% | 0.9 |
| History | C | 2.0 | 30% | 0.6 |
Add all weighted points, then divide by the total weight.
That is a B overall since 3.1 falls between 3.0 (B) and 4.0 (A).
Convert back to a letter grade using a standard scale
| GPA | Letter |
|---|---|
| 3.5–4.0 | A |
| 2.5–3.49 | B |
| 1.5–2.49 | C |
| 0.5–1.49 | D |
| 0–0.49 | F |
Weighted Grade Formula A–F system
Turn each letter grade into a number
A = 4, B = 3, C = 2, D = 1, F = 0
Formula
- G1,G2,G3,… = grade points (A=4, etc.)
- W1,W2,W3,…= weights (like % or credit hours)
| Subject | Grade | Grade Point | Weight |
|---|---|---|---|
| Math | A | 4 | 3 |
| English | B | 3 | 2 |
| History | C | 2 | 1 |
That is the result that comes to 84.00% (B) ✨
