Calculate weighted grades from editable categories and scores. Choose how missing scores are handled and review each category contribution before using the result.
Edit category weights and percentages. Missing-score handling is explicit; no official policy or conversion table is assumed.
Grade Calculator supports customizable weighted grading instead of assuming one policy fits every class. Edit category names and weights, enter each category percentage, and see the weighted contribution and overall result. The tool warns when weights do not total 100 percent and lets you choose whether missing category scores are excluded, treated as zero or flagged as incomplete. It does not apply an official transmutation table by default. If your school uses a conversion table, enter and verify it yourself. Keep student data private; calculations remain in this browser.
Use the tool as a starting point, verify outputs before relying on them, and keep a separate copy of important source data. The interface is designed to work in the browser without an account. The calculations and file checks are intended to make routine work easier, not replace professional judgment or your organization's policies. Before printing, sharing, or issuing an output, review the details carefully and keep a separate backup of important records. This beta release should be tested with representative examples before you depend on it for time-sensitive work. Features that are not yet implemented are disclosed in the interface rather than shown as working controls.
Practical, plain-language advice written alongside the tool.
No official policy is assumed. Configure the weights and conversion rules required by your school.
Choose whether missing categories are excluded, treated as zero or flagged as incomplete; the tool does not silently decide.
