What this website provides
Gradebook Tools is an independent collection of free grade calculators and reference charts for students and teachers. No account or purchase is required.
Use the gradebook calculator for weighted course averages, the final grade calculator for one remaining final exam, or the teacher grader for a class taking the same test.
Publishing and maintenance
Gradebook Tools is the publishing and maintenance identity for this website. We maintain its formulas, worked examples, input checks, and documentation. The site is not affiliated with a school, and its results are estimates rather than official academic records.
Our calculation checks explain the examples we verify. The correction log records material calculation corrections. Your school’s syllabus remains the authority for grading rules.
Data and transparency
Calculations run in your browser. Local saves require an explicit Save action and do not sync between devices. Read the privacy and storage explanation, terms of use, and reference sources.
