Terms of Use

Last updated: November 2026.

Using TeacherCalc

TeacherCalc provides free online grade calculators and educational articles. By using this site you accept these terms. The tools are provided for personal and classroom use, for planning, estimation and checking grade arithmetic.

Accuracy

We work to keep formulas and grading scales accurate against published standards, and every tool page shows its formula and a worked example so results can be verified. Grading policies, however, vary between schools, districts, universities and individual courses, and rounding and moderation decisions can change a final recorded grade. TeacherCalc results are estimates. The official grade in any dispute is the one recorded by your educational institution, and we are not responsible for decisions made in reliance on an estimate.

Acceptable use

You may use the calculators freely, link to any page, and print grading charts for classroom use. You may not attempt to disrupt the site, scrape it at a scale that degrades service for others, or present TeacherCalc results as official institutional grades.

Intellectual property

The articles, design and code of this site belong to TeacherCalc. Short quotations with a link are welcome. The underlying grading formulas and scale tables are standard published information.

External links and advertising

Pages may contain advertisements served by Google AdSense and occasional links to external resources. We do not control the content of external sites or advertisements and are not responsible for them.

Changes

We may update these terms or modify and discontinue tools at any time; the current version will always be posted on this page. Continued use of the site after a change means you accept the updated terms.
