Assignment Weight Calculator
Calculate your overall grade when assignments are weighted differently (e.g., homework 20%, exams 50%).

Calculate your final grade based on weighted assignments
Final = Σ (Score * Weight%) / Σ Weight% No calculations yet.
How to Calculate
Weighted Grade = Σ (Category Score % × Category Weight %)
Weighted Grade = Σ (Category Score % × Category Weight %) ÷ 100. Total Course Weight must sum to 100%.
* Example: Homework 90% (worth 20%) + Exam 80% (worth 80%) → 82% final
Step-by-Step Manual Calculation Guide
Step 1: Multiply each assignment score percentage by its syllabus weight percentage.
Step 2: Sum all weighted category products together.
Step 3: Divide by total weight percentage (usually 100%) to get your final course grade.

Syllabus Grade Tracking
Computing course grade with Homework (20% weight, 90% score), Midterm (30% weight, 80% score), and Final (50% weight, 85% score) = 84.5% final grade.

Frequently Asked Questions
How do weighted grades work?
Weighted grades assign relative importance to different assignment categories regardless of raw point counts. An exam weighted at 40% has twice the impact of a paper weighted at 20%.
How do I calculate weighted grade manually?
Multiply each percentage grade by its decimal weight and add the results together. Example: (90% × 0.20) + (80% × 0.80) = 18 + 64 = 82%.
What if my weighted categories don't add up to 100% yet?
Divide your current weighted sum by the sum of completed category weights to find your current course standing.
Why is a 100-point final exam worth more than 100 points of homework?
Because the syllabus assigns a higher category weight percentage to the final exam.
Can a high final exam score save a low overall grade?
Yes, if the final exam carries a heavy category weight (such as 40% or 50% of the course grade).
