How to use the Weighted Grade Calculator
- Enter each category or assignment with its score and weight from the syllabus.
- Leave the score blank for anything not graded yet.
- Read your current weighted grade and how much of the course is still to come.
What does this tool do?
Most courses weight categories differently — for example homework 20%, quizzes 15%, midterm 25% and final 40%. A weighted average multiplies each score by its weight, so a high homework score can't hide a low exam score.
Ungraded items are left out, and the remaining weights are scaled up, which shows your grade based on the work marked so far.
Why use it?
- Know where you stand mid-semester.
- See which category matters most.
- Pair it with the Final Exam Grade Calculator to plan.
Example
Homework 92% (20%), quizzes 85% (15%) and midterm 78% (25%) with the final not yet taken: (92×20 + 85×15 + 78×25) ÷ 60 = 84.4%.

Frequently asked questions
Why is a weighted average different from a simple average?
A simple average treats every score equally. A weighted average gives each category its share of the final grade, so a 40% final exam counts four times as much as a 10% homework category.
How do I turn my percentage into a letter grade?
Check your syllabus, as scales differ. A common US scale is A for 90–100%, B for 80–89%, C for 70–79% and D for 60–69%.
