Weight assignments inside one course: add a row per assignment with your score, max points, and weight %. Use the sample preset for 30%+30%+40% splits. Get a weighted percentage and reference letter band.
What to enter
Each row is one graded item: score, max points, and weight %. Weights are relative—they do not have to sum to exactly 100.
vs GPA
GPA calculator is for multiple courses and credit hours; this page weights items within a single course.
Letter grades
Cutoffs are generic—follow your syllabus.
vs test score tool
One quiz with correct/total only? Use the test grade calculator.
Frequently asked questions
Final grade with 30% homework, 30% midterm, 40% final?
Convert each part to percent (score ÷ max), then combine: e.g. 85/100×30% + 92/100×30% + 78/100×40% = 84.3%. Enter three rows with score, max, and weight % on this page.
Weighted course grade formula
Course % = Σ(score ÷ max × weight) ÷ Σ weights. Different max points per item are fine—each becomes a percentage first.
Combine homework, quizzes, and exams into one grade?
Add one row per graded item: score, max, weight % from the syllabus. For a single correct/total quiz, use the test grade calculator instead.
Assignment out of 20 or 50 points?
Enter the real max (e.g. 20) and your score (e.g. 18) plus weight %. The tool uses score ÷ max—no need to convert to /100 first.
Do weights have to add up to 100?
No—30/30/40 and 3/3/4 give the same result. Only the ratio matters.
Grade calculator vs GPA calculator?
This page weights items inside one course. The GPA calculator combines multiple courses with credit hours.
What letter grade is my percentage?
The page shows a reference letter band (generic US-style cutoffs). Follow your syllabus—do not rely on it alone for pass/fail.
Can I save my inputs?
Yes. Copy link below the form keeps your current inputs so you can share the scenario or save it for later.
