## Overview

This calculator finds your overall course grade by combining each graded category — homework, quizzes, exams, and any other component — according to the weight your instructor assigns to it. Enter a category name, its percentage weight, and the score you earned, then add as many rows as your syllabus requires. Unlike a simple average, the weighted method reflects how much each component actually counts toward your final mark.

## How to read your result

The headline figure is your overall course grade as a percentage, followed by the equivalent letter grade (A/B/C/D/F). The stacked bar beneath the result shows each category's proportional contribution to that grade: a wider segment means the category carries more weight or a higher score. When the total of your weights does not equal 100%, the calculator normalises by the actual total — so the grade is still correct, but a note appears reminding you that weights are incomplete. The legend lists each category's name and the exact number of percentage points it contributed.

## Method

The weighted grade formula is grade = Σ(wᵢ × sᵢ) / Σwᵢ, where wᵢ is the weight of category i and sᵢ is the score earned. Dividing by the actual sum of weights rather than a fixed 100 ensures the result is defined and correct even when categories are incomplete. A parallel quantity, the raw weighted sum = Σ(wᵢ/100 × sᵢ), shows each category's direct contribution to a 0–100 grade scale under the assumption that all weights will eventually total 100; when they do, both quantities are equal.

## Example

- **Setup:** Three categories: Homework worth 20% with a score of 90, Quizzes worth 30% with a score of 80, Final Exam worth 50% with a score of 70.
- **Result:** The calculator returns an overall grade of 77% (letter grade C). Homework contributes 18 points, Quizzes contribute 24 points, and the Final Exam contributes 35 points, summing to 77.

## Frequently asked questions

### How is the weighted grade calculated?

Each category's score is multiplied by its weight, and those products are summed and then divided by the total of all weights. The formula is grade = Σ(weight × score) / Σweight. Dividing by the actual total weight — rather than always by 100 — keeps the result accurate even when weights are incomplete.

### What happens when my weights do not add up to 100%?

The calculator still produces a valid grade by normalising against whatever the weights total. For example, if only three of four graded components have been entered and they total 90%, the result reflects your performance on those three components only. A warning note appears so you know the picture is partial.

### How is this different from the GPA weighted-grade calculator?

This calculator works within a single course: you enter category weights (homework 20%, exams 50%) and compute one overall course grade as a percentage. The GPA weighted-grade calculator works across multiple courses: it takes each course's grade and credit-hour weight to compute a semester or cumulative GPA.

### Can I use scores above 100 for extra credit?

Yes. The score field accepts any finite number, so entering 105 for a category with extra credit is valid. The contribution of that category will exceed its weight, which can push the overall grade above the base ceiling.

### What is the minimum grade I need on the final exam to pass?

This calculator shows your current grade. To find the required final-exam score, use the companion Final Grade Calculator, which solves for the missing score needed to hit a target.
