How It Works
A weighted grade calculator accounts for the fact that not all assignments carry equal importance. A final exam worth 50% of your grade has five times more impact than a quiz worth 10%. Enter each category, its percentage weight, and your score to see your true overall grade.
Example:
- Homework: 20% weight, score 85% → contributes 17 points
- Midterm: 30% weight, score 78% → contributes 23.4 points
- Final Exam: 50% weight, score 92% → contributes 46 points
- Total: 17 + 23.4 + 46 = 86.4% (B)
Frequently Asked Questions
What is a weighted grade?
A weighted grade accounts for the fact that different assignments or categories count for different portions of your final grade. For example, a final exam worth 50% has more impact than a homework assignment worth 10%.
How is a weighted grade calculated?
Multiply each category's grade by its weight, add the results together, then divide by the total weight. For example: (85 × 20) + (78 × 30) + (92 × 50) divided by 100 = 86.5%.
Do the weights have to add up to 100%?
No. The calculator normalizes automatically. If your weights add up to more or less than 100%, it still calculates the correct weighted average based on the relative weights you entered.
What if I don't know all my grades yet?
Leave unknown grades blank. The calculator only uses rows where both a weight and a grade are filled in, so partial results are still accurate for the categories you've completed.
What is the difference between weighted and simple average?
A simple average treats every score equally. A weighted average gives more importance to categories with higher weights. If your final exam is worth 50%, a bad score there hurts much more than a bad homework grade worth 10%.
