Terms of use

Last updated: June 2026

By using Wedding Math, you agree to these terms. If you do not agree, please don't use the site.

Estimates only — not professional advice

All calculators provide planning estimates based on common rules of thumb. They are not financial, legal, catering, or event-planning advice. Real costs and quantities vary by region, vendor, season, and many factors the calculators cannot know. Always confirm final numbers, contracts, and quantities with your venue and vendors before making purchases or commitments.

No warranty

The site and its results are provided “as is,” without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or availability. We do not guarantee that any estimate will match your actual needs or costs.

Limitation of liability

To the fullest extent permitted by law, Wedding Math and its creators are not liable for any loss or damage arising from your use of the site or reliance on its estimates, including over- or under-purchasing, budget overruns, or planning decisions.

Responsible use

Some tools (such as the alcohol calculator) relate to activities with legal and safety considerations. You are responsible for complying with local laws, serving alcohol only to guests of legal drinking age, and arranging responsible service and transportation.

Changes

We may update these terms and the calculators over time. Continued use after changes means you accept the updated terms.
