By using percentages.co.uk, including all calculators, worksheets, practice questions, revision resources, embeddable calculators and the API, you agree to these terms. If you do not agree, please do not use the site.

2. Use of calculators

All calculators are provided free of charge for personal, educational and professional use. Results are provided for informational and educational purposes only and must not be relied upon for financial, legal, tax, medical or academic decisions without independent verification. We make every effort to ensure accuracy but cannot guarantee results are error-free in all circumstances.

All worksheets and revision resources on the site are free to print and use for personal and classroom educational use. Teachers may print and distribute worksheets to their students at no charge.

Worksheets must not be sold, repackaged or published on other websites without our written permission. The percentages.co.uk credit on worksheets must be retained when printed and distributed.

Third parties may embed our calculators on their own websites using the iframe embed code provided on the site. The following conditions apply to embedding:

• The embed must not be used on websites containing illegal content, adult content, hate speech or content that promotes harm
• We reserve the right to withdraw embed access at any time
• We accept no responsibility for how embedded calculators are used on third-party sites
• Embedding a calculator does not create any partnership or endorsement relationship with percentages.co.uk

5. API usage

The free API at /api/calculate is provided for non-commercial use only. Commercial use requires written permission. We reserve the right to rate-limit or withdraw API access at any time.

The API must not be used in a way that places unreasonable load on our servers. We accept no liability for any decisions made based on API results.

7. Accuracy and liability

We take care to ensure all calculations and educational content are accurate and aligned to the UK national curriculum and current UK rates including VAT and tax rates. However, we accept no liability for any errors, omissions or outdated information. Users should verify any important calculations independently.

Results from grade calculators are indicative only. Actual grade boundaries are set by exam boards and universities after each assessment period and may differ. Always refer to your official exam board or institution for confirmed grade boundaries.
