Weighted Grade Calculator
Calculate your final grade using weighted categories, score percentages, and optional missing-category handling
Estimated time
2 min
Weighted Categories
Add each grade category with its weight and current score percentage.
Formula Summary
Category contribution = (weight% x score%) / 100
Include missing ON: final grade = sum of contributions
Include missing OFF: final grade = (sum of contributions / total entered weight) x 100
How It Works
Use this calculator to estimate your final course grade when each category has a different weight.
Add as many categories as needed, then choose whether missing weight should be treated as zero or ignored.
- Category contribution = (weight% x score%) / 100.
- If "Include missing categories" is ON, final grade = sum of category contributions.
- If it is OFF, final grade is normalized to entered categories only.
- Entered weights below 100% are treated as incomplete weighting and shown as missing weight.
- Weights above 100% are allowed but flagged so you can correct category setup.
Example Calculations
Full weighted grade (100% entered)
Final grade = 86.40%
Partial grading period, normalize entered categories
Final grade = 86.00% (based on 50% entered weight)
Partial grading period, count missing as zero
Final grade = 43.00% (remaining 50% treated as 0)
Frequently Asked Questions
Should my category weights add up to 100%?
Yes for a full-course estimate. If they do not total 100, use the missing-categories toggle based on how your teacher handles ungraded categories.
What does "Include missing categories" do?
When enabled, any unentered weight below 100% is counted as zero in your final grade. When disabled, only entered categories are used.
Can I use points instead of percentages?
Yes. Convert each category score to a percentage first, then enter that percentage in the score field.
Why is my grade above 100%?
That can happen if entered weights exceed 100% or if categories include extra credit. The calculator flags overweight totals so you can review them.
