Weighted Grade Calculator
Calculate your overall course grade from scores with different weights.
How to Use the Weighted Grade Calculator
Enter each grade and its weight to calculate the weighted course average.
Practical Example
A score of 80 worth 40% and a score of 90 worth 60% produce a weighted grade of 86.
Factors That Affect the Result
Weights must match the course structure. Missing categories, bonus points and dropped assignments can change the official result.
Frequently Asked Questions
Must weights total 100%?
For a full-course estimate, usually yes.
Can weights be decimals?
Yes.
Is this the same as a simple average?
No. Higher-weight items influence the result more.

How Weighted Grades Are Calculated
A weighted grade gives different assignments, exams or categories different levels of importance. The general method multiplies each score by its weight and then adds the weighted results. For example, if exams are 60% of the course and assignments are 40%, an 80 exam average and 90 assignment average produce 80 × 0.60 + 90 × 0.40 = 84. Weights should normally total 100% unless the course uses extra credit or another special system. If some categories have not yet been graded, check whether your instructor excludes them temporarily or treats them as zeros. A calculator can estimate your current standing, but the official course grade depends on the syllabus rules, rounding policy, dropped scores, extra credit and any minimum requirements. Use the exact weights published by the instructor for the most meaningful result.
