Weighted Grade Calculator guide
Combine assignment or category scores using explicit weights and compare the result with an unweighted points percentage.
What this tool does
The Weighted Grade Calculator accepts up to ten grade components. Each row contains points earned, maximum points, and a relative weight. The tool converts each component to a percentage, multiplies it by its weight, and divides the total weighted points by the sum of entered weights.
Because the result is normalized, weights do not have to total exactly 100. Weights of 3, 3, and 4 produce the same normalized grade as 30, 30, and 40. The report displays the entered weight total so you can detect an incomplete category list or a mistaken value.
It also reports the unweighted points grade by dividing all points earned by all possible points. That number can differ from the weighted grade when components have different weights relative to their point totals.
How to use it
- Enter the score earned and maximum score for each component.
- Enter the relative weight specified by the course or assessment plan.
- Add or remove rows as needed.
- Select Calculate weighted grade.
- Compare the normalized weighted grade with the points-based result and verify the weight total.
Scores above the maximum are allowed because some systems use extra credit. Confirm how the actual gradebook treats those points.
Use the Percentage Calculator for one score as a share of a total. To summarize an unweighted list of numeric results, use the Statistics Calculator.
Benefits
- Supports one to ten independently weighted components
- Normalizes weights that do not sum to 100
- Shows the entered total weight prominently
- Compares weighted and raw points percentages
- Performs all grade calculations locally
Policy and rounding differences
This calculator applies a direct mathematical weighted average. It does not know whether an institution drops the lowest score, caps a category, treats missing work as zero, rounds intermediate values, adds extra credit separately, or requires a minimum exam score. Gradebook software may also retain more decimal places than the displayed interface.
Enter category averages when the syllabus weights categories, and enter individual assignments only when each assignment has its own weight. Mixing both levels can count the same work twice.
Educational notice: The result is an estimate, not an official grade. The instructor or institution's published policy and gradebook determine the recorded result.
