What is a weighted grade?
A weighted grade gives some parts of a class more influence than others. If exams are 50% of the grade and homework is 10%, a 70 on an exam pulls your grade down five times as much as a 70 on homework. To calculate it, multiply each category score by its weight, add the products and divide by the total of the weights. This weighted grade calculator does that for any number of categories, and it also works when your teacher uses points instead (each assignment is weighted by its points possible). It handles weights that add up to less or more than 100%, and it tells you the average you need on the categories you have not finished yet.
How to calculate a weighted grade
- Add a row for each category in your syllabus, for example Homework 20, Quizzes 15, Midterm 25, Final 25.
- Enter your score for each category. If the category has several assignments, use their average or the total points such as 186/200.
- Leave the score blank for categories that are not graded yet. Your weighted grade is calculated from the rest.
- Switch to Points if your teacher grades by total points instead of percentages, then enter points earned and points possible for each assignment.
Why use this weighted grade calculator
- Weights that do not add to 100If your weights add to 85%, the missing 15% is treated as work still to come. If they add to 120%, each weight counts as its share of 120. A note under the result says which.
- Type scores the way you have themEnter 88, 88%, 44/50, 18 out of 20 or a letter like B+. Extra credit above 100% is allowed. You never have to convert anything first.
- What you need for every letterInstead of one answer for one target, you get a table with the score needed for an A, A-, B+ and every other grade, marked as already secured, reachable or not possible without extra credit.
- Weights or pointsSwitch between percent weights and points-based grading without retyping your categories. The same rows keep both sets of numbers.
- Your school’s grading scaleChoose plus/minus with or without A+, or a simple 10-point scale, then edit any cutoff to match your syllabus. Every result updates at once.
- Saved on your device, privateYour classes and scores are kept in this browser, so they are still there next time. Nothing is sent to a server and there is no account to create.
Common uses for a weighted grade calculator
- Checking your grade against the syllabus. Copy the categories and weights from the syllabus, add your scores from Canvas, Blackboard or Google Classroom, and see where you stand.
- Missing or late work. Leave a score blank to see the grade without it, or enter 0 to see what a missing assignment really costs.
- What-if scenarios. Try a 70, an 85 and a 95 on the next test and watch the course grade change before you decide whether to retake a quiz or drop a class.
- Comparing two syllabi. See how the same scores turn into different grades when exams count 40% in one section and 60% in another.
- Planning for finals week. See which classes need a big score on the final and which are already safe, so you can spend your study time where it matters.
- Parents following progress. Enter the scores from the parent portal and see what your child needs on the rest of the term, explained in plain numbers.
Grade formulas, with examples
These are the formulas the calculator uses. Weights are percentages, or decimals where the formula says so (25% = 0.25).
- Weighted grade
- (score₁ × weight₁ + score₂ × weight₂ + …) ÷ (weight₁ + weight₂ + …)
- Example: (95 × 20 + 88 × 15 + 82 × 25 + 90 × 15) ÷ 75 = 88.27%
- Points grade
- total points earned ÷ total points possible × 100
- Example: 405 ÷ 450 × 100 = 90%
- Score needed on the final
- (target - current × (1 - final weight)) ÷ final weight
- Example: (90 - 88 × 0.75) ÷ 0.25 = 96%
- Grade after the final
- current × (1 - final weight) + final score × final weight
- Example: 88 × 0.75 + 80 × 0.25 = 86%
- Test score
- (questions - wrong) ÷ questions × 100
- Example: (20 - 3) ÷ 20 × 100 = 85%
Letter grade scale: percentages for A to F
Most US high schools and colleges use the plus/minus scale below. Some stop at A (no A+), and many high schools use a simple 10-point scale (A 90, B 80, C 70, D 60). Your syllabus has the final word, and you can change every cutoff in the calculator.
| Letter | Percentage | Letter | Percentage |
|---|---|---|---|
| A+ | 97 to 100 | C | 73 to 76.99 |
| A | 93 to 96.99 | C- | 70 to 72.99 |
| A- | 90 to 92.99 | D+ | 67 to 69.99 |
| B+ | 87 to 89.99 | D | 63 to 66.99 |
| B | 83 to 86.99 | D- | 60 to 62.99 |
| B- | 80 to 82.99 | F | Below 60 |
| C+ | 77 to 79.99 |

Example: weights that add up to 75%
Homework 95 at 20%, quizzes 88 at 15%, midterm 82 at 25% and projects 90 at 15%. That is 75% of the course. Weighted grade: (95 × 20 + 88 × 15 + 82 × 25 + 90 × 15) ÷ 75 = 6,620 ÷ 75 = 88.27%. The missing 25% is the final. Add it as a row with no score, or leave it out: either way you need 95.2% on it for an A- and 83.2% for a B+.
What to expect from the result
The result is only as accurate as the weights and scores you enter, so check them against your syllabus and gradebook. Some teachers drop the lowest quiz, curve a test, round 89.5 up or weight categories by points instead of percent; the calculator does not guess any of these. Letters typed as scores count as the middle of their range. Your school’s official grade is the one in its gradebook.
Weighted Grade Calculator questions
How do I calculate my weighted grade?
Multiply each category score by its weight, add the results, and divide by the total of the weights. For homework 95 (20%), quizzes 88 (15%), midterm 82 (25%) and projects 90 (15%): (95×20 + 88×15 + 82×25 + 90×15) ÷ 75 = 88.27%, a B+.
What if my weights do not add up to 100%?
If they add to less than 100%, the rest of the course is treated as not graded yet, and the calculator tells you what you need on that remaining part. If they add to more than 100%, each weight counts as its share of the total, so weights of 60 and 60 are treated as 50% each. A note under the result says which rule was used.
What is the difference between weighted and points grading?
With weights, each category counts for a fixed percentage no matter how many assignments it has. With points, every assignment counts by its points possible, so a 200-point exam counts twice as much as a 100-point one. Switch between the two with the Weights and Points buttons.
How do I calculate a category average?
Add the points you earned in the category and divide by the points possible, or enter the total as a fraction such as 186/200. If every assignment in the category is worth the same, the average of the percentages gives the same result.
