Grade Calculator
Calculate a weighted course percentage from scores and weights, with the grading scale shown clearly.
Scores and weights
Use any positive weights: percentages, points, or credits. Only their relative size matters.

How it works
Grade Calculator: a practical guide
A weighted grade calculator combines scores that do not all count equally. Enter a score and a positive weight for each assignment, exam, or category to calculate the weighted percentage; the page then applies its stated A–F scale as a quick reference.
- STEP 01
Enter each score as a percentage from 0 to 100.
- STEP 02
Enter a positive weight beside every score. The weights can be percentages, points, or credits.
- STEP 03
Calculate the weighted percentage, then compare it with your course's actual grading policy.
What this tool does and its limits
Each score is multiplied by its weight, then the weighted scores are divided by the total weight. The weights do not need to add to 100: 20, 30, and 50 produce the same result as 2, 3, and 5. The displayed A–F label is only this page's simple reference scale. It does not account for dropped work, curves, category minimums, rounding policies, extra credit, incomplete grades, or any instructor-specific rules.
Inputs, selected files, and results stay in your browser. The tool does not upload them to Got A Tool or save them to persistent storage.
Questions
Grade Calculator details
Do my weights need to total 100?
No. The tool divides by the total weight you enter, so any positive proportional weights work. For example, 25/25/50 and 1/1/2 represent the same weighting.
Which letter-grade scale is used?
This page uses A at 90 or above, B at 80 or above, C at 70 or above, D at 60 or above, and F below 60. A course can use a different scale.
Can I calculate a final grade with one missing assignment?
You can include a placeholder score to explore a scenario, but the calculator does not predict future scores or infer missing work.
Does this replace my course gradebook?
No. Treat it as a transparent check. The instructor's grading policy, official gradebook, rounding, curves, and adjustments determine the actual grade.
