Terms of Use — 5 Key Rules for Using Our Calculators
Last updated: July 2026
These Terms of Use apply to gradecalculator360.com and every calculator, page, and resource published on GradeCalculator360. By using this website, you agree to the terms described below. If you do not agree with any part of these terms of use, please discontinue using the site. We've kept this page as clear and short as possible while still covering what you should know before relying on any of our tools.
Clear rules, no surprises — how our calculators may be used
Terms of Use: Rule 1 — Free Use of the Service
GradeCalculator360 provides free online grade calculators — including our final grade calculator, weighted grade calculator, and semester grade calculator — for personal, educational use. You may use every tool without creating an account, for any lawful purpose, on any device. Under these terms of use, you may not attempt to disrupt the site, scrape it at abusive volume, reverse-engineer the calculators for republication, or misrepresent the results as official school records.
Terms of Use: Rule 2 — Educational Estimates, Not Official Records
All results produced by our calculators are estimates based on the numbers and weights you enter and on standard US grading conventions. Schools, districts, and instructors apply their own policies — rounding rules, dropped scores, extra credit, category caps, and replacement policies — which can change the actual outcome. Your institution's gradebook and syllabus are the only official record. Always verify important results with your teacher, professor, or registrar before making academic decisions based on any calculator output. This same principle is covered in more detail in our Disclaimer.
For general context on how grading conventions can vary between institutions, Wikipedia's overview of academic grading in the United States may be helpful — though as always, your own school's specific policy governs your actual recorded grade, not any external resource or calculator.
Terms of Use: Rule 3 — No Warranty
The service is provided "as is," without warranties of any kind, express or implied. We work hard on accuracy and show every formula so results can be independently verified, but we do not guarantee that the service will be error-free or uninterrupted, and we accept no liability for decisions made based on calculator output. Using this site under these terms of use means accepting that all results are informational, not a substitute for official academic advice.
Terms of Use: Rule 4 — Intellectual Property
The design, text, and code of GradeCalculator360 are the property of the site owner. You are welcome to link to any page on this site from your own website, blog, or resource list. You may not copy our pages, calculators, or written content for republication elsewhere without permission. If you'd like to request permission to reuse any content, you can reach us through our Contact page.
Terms of Use: Rule 5 — Advertising
This site displays third-party advertising, which funds free access to every calculator we publish. Advertisers are responsible for their own content, offers, and landing pages — we do not control or endorse individual ads shown through our advertising partners.
