How to Use Grade Calculator
Grade Calculator Formula / How It Works
The tool uses client-side JavaScript to perform calculations instantly inside your browser. For weighted grades, it calculates the sum of all weighted scores divided by total weights. For point-based grades, it divides total earned points by total max points. For final exam planning, it back-calculates the required final score to achieve the target class grade based on the relative weights.
For example, in weighted mode, if your Homework grade is 90% (weighted at 30%) and your Exams grade is 80% (weighted at 70%), the tool computes: (90 × 30 + 80 × 70) / 100 = 83.00% (B-).
Frequently Asked Questions
It calculates a weighted average of all your assignments, quizzes, and exams based on the percentage weights you assign to each category. The final grade equals the sum of (category score × category weight) across all categories.
By default it uses the standard US letter grade scale (A = 90–100, B = 80–89, C = 70–79, D = 60–69, F = below 60). You can adjust the weights to match your specific course grading policy.
Yes. Enter only the assignments you have received grades for and set their weights accordingly. The calculator will compute your current grade based on completed work only.
The calculation is mathematically exact using standard weighted average arithmetic. Results match what your teacher or professor would calculate using the same weights and scores you provide.
No. All calculations run locally in your browser. Your grades and course data are never sent to any server or stored anywhere.
