Homework, quizzes, midterm, project, and so on, with the percent score you have so far.

Use the weight from the syllabus (percent or points). Partial terms are fine.

Optional: target and remaining
Add a target grade and remaining weight to see what you need on unfinished work.
Why weight categories
Syllabi rarely treat every assignment equally. Match the weights your instructor published.
Partial courses
Enter only graded categories. Weights normalize over what you include.
Same engine as class grade
This tool and the [class grade calculator](/tools/class-grade-calculator) share the same formula; this page is named for weighted-syllabus searches.
When to use weighted grades

Weighted grade formula
Grade = Σ (score × weight) ÷ Σ weight
Score is a percentage (0–100). Weight is the syllabus share for that category.

Frequently asked questions
How does a weighted grade calculator work?
Multiply each category score by its weight, add the products, divide by the sum of weights.
Example: homework 90 at 25% and exam 80 at 75% → (90×25 + 80×75) ÷ 100 = 82.5%.
Do weights need to add to 100%?
No. Enter weights as written. The calculator divides by the total of the rows you filled in.
How do I find what I need on the final?
Enter your current categories, then set target grade and remaining weight (the final’s share). Or use the dedicated final exam grade calculator.
What letter scale do you use?
A common US plus/minus scale with 4.0 GPA points. Your school may differ; trust the percentage first.
Are my grades stored?
No. Everything runs locally in your browser.
