Formula
How it works: Each grade contributes according to its assessment weight.
Worked Example
How Weighted Grade Averages Work
A weighted average gives more importance to higher-weighted assessments. This reflects how most courses structure grading: a final exam worth 40% counts more than a quiz worth 5%.
- Each grade is multiplied by its weight percentage, and the products are summed
- The sum is divided by the total of all weights to produce the weighted average
- Drop lowest option: removes the lowest-scoring assessment before averaging, which many professors offer as a grading policy
- Equal weights produce a simple average. Different weights reflect the relative importance of each assessment in the course
Use this calculator throughout the semester to track your running course average and plan which remaining assessments to prioritize.
You can also calculate changes using our Final Grade Calculator, Marks Percentage Calculator, Test Grade Calculator or Semester GPA Calculator.
Frequently Asked Questions
What is a weighted average grade?
A weighted average multiplies each grade by its assigned weight (percentage of the total course grade) before averaging. This means a test worth 30% of your grade counts three times more than a quiz worth 10%.
Can I drop the lowest score?
Yes. Enable the drop lowest option to remove your lowest assessment score before calculating the average. This mimics the common grading policy many professors use.
Do the weights need to add up to 100?
Ideally yes, if the weights represent the full course grading breakdown. If you enter partial weights (only the assessments completed so far), the calculator still computes a valid weighted average of those components.
How is this different from GPA?
This calculator averages numerical grades (like 85, 92, 78) with weights. GPA converts letter grades to grade points (A=4.0) and weights by credit hours. Both are weighted averages, but they use different scales.
