Find the weights in your syllabus
Look for the percentage assigned to homework, quizzes, projects, midterms, and finals. You can also enter individual assignments when each one has its own weight.
Add your graded work
Use either categories or individual assignments.
% weights mode — use this when your syllabus gives each category a percentage weight (e.g. Homework 20%, Final 40%). Enter each score as a percentage.
| Item or category | Grade | Weight |
|---|
Grades may be above 100% for extra credit. Weights should be between 0% and 100%.
| Item or category | Earned pts | Possible pts |
|---|
Enter the points you earned and the points possible for each item. Extra credit is fine — earned points may exceed possible points.
How to use it
From syllabus to answer in three steps.
Enter each score and weight
A score of 88% in a category worth 25% contributes 22 points to the course grade: 88 × 0.25 = 22.
Read the right result
If your weights total less than 100%, “current grade” normalizes only the work entered. “Course points earned” shows how many points those items contribute to the full course.
Worked example
How a weighted grade is calculated
Suppose homework is 20% of the course, quizzes are 30%, and a midterm is 50%. Multiply each score by its decimal weight and add the contributions.
Homework90 × .20 = 18.0
Quizzes82 × .30 = 24.6
Midterm88 × .50 = 44.0
Weighted grade86.6%
Points mode
How a points-based grade is calculated
Switch the calculator above to Points mode when your syllabus lists raw points instead of percentage weights. Add up all earned points, add up all possible points, and divide. Larger assignments automatically count more because they contribute more possible points.
When to use which mode: use % weights when the syllabus says "Final = 40%"; use Points when it says "Final = 200 points out of 1000 total". Both modes give the same answer whenever the weights match the point proportions.
Exam 142 / 50
Exam 247 / 50
Quiz 318 / 20
Homework95 / 100
Points grade202 ÷ 220 = 91.8%
Weighted grade
Some work counts more than others. A final worth 40% affects your result more than a quiz worth 5%, even if both are scored out of 100.
Unweighted average
Every score counts equally. Add the scores and divide by the number of scores. This only works when all items carry the same importance.

Common questions
Weighted grade calculator FAQ
How do I calculate a weighted grade?
Convert every weight from a percentage to a decimal, multiply each grade by its weight, and add the products. If the entered weights total less than 100%, divide the result by the total weight as a decimal to get your current grade on completed work.
What if my grade weights do not add up to 100%?
That is normal when some work is not graded yet. This calculator shows both the normalized current grade and the points earned toward the full course. If all categories are included, recheck the syllabus because the weights should usually total 100%.
What score do I need on my final exam?
Use the “Final grade needed” tab. The calculation is: required final score = (desired overall grade − current grade × remaining course weight) ÷ final exam weight. Enter weights as percentages; the calculator handles the conversion.
Can a required final score be over 100%?
Yes. A result above 100% means the target is not reachable under a standard 100-point final unless extra credit is available. A result below 0% means you have already secured the target even with a zero on the final.
How much will one assignment change my grade?
Multiply the difference between the new score and your current grade by the assignment’s decimal weight. For example, scoring 10 points above your current grade on an assignment worth 20% raises the final course grade by about 2 points.
Is a weighted grade the same as a weighted GPA?
No. A weighted grade combines course components into one percentage. A weighted GPA adds extra grade points for honors, AP, or advanced courses according to a school’s own scale.
What letter-grade scale does this calculator use?
The displayed letter is a general reference: A = 90 and above, B = 80–89.99, C = 70–79.99, D = 60–69.99, and F = below 60. Your school or instructor may use a different scale, plus/minus grades, or rounding rules.
Is this a grade calculator weighted by class category?
Yes. Enter each category — homework, quizzes, labs, exams — with its weight from your syllabus, and this grade calculator weighted by category computes your overall percentage instantly.
How does a weighted average grade calculator work?
A weighted average grade calculator multiplies each score by its category weight, adds those products, and divides by the total weight. That is exactly what the calculator above does — your syllabus weights decide how much each part counts.
Is this a grade calculator with weighted categories?
Yes — as a weighted class grade calculator, it accepts any categories your class uses — participation, projects, midterms — with any weights. If your weights do not total 100%, it normalizes the result so you see your current standing on completed work.
