Terms of Use

By using Guest Formula, you agree to use the calculator as a general planning aid and to exercise your own judgment before making purchases or serving guests.

Planning estimates only

All quantities, portions, costs and budget comparisons are estimates based on generalized assumptions. Actual needs and prices vary with guest preferences, age, event length, weather, menu, portion size, local prices, waste and other circumstances. Results are not guarantees.

No professional advice

Guest Formula does not provide catering, dietary, nutritional, medical, allergy, food-safety, legal, financial or alcohol-consumption advice. Consult an appropriate qualified professional when your event involves specialized needs or material risk.

Food safety and dietary needs

You are responsible for food storage, preparation, temperature control, allergen precautions, dietary accommodations and compliance with applicable health and safety requirements.

Alcohol

Alcohol estimates are intended only for lawful planning by adults of legal drinking age. You are responsible for verifying age, complying with local laws, preventing service to minors or visibly impaired people, arranging safe transportation and serving responsibly.

Acceptable use

You may use the site for lawful personal or business planning. You may not misuse the site, interfere with its operation, attempt unauthorized access, or use automated activity that unreasonably burdens the service.

Disclaimer of warranties

To the maximum extent permitted by applicable law, the site is provided “as is” and “as available,” without warranties of accuracy, fitness for a particular purpose, merchantability or non-infringement.

Limitation of liability

To the maximum extent permitted by applicable law, Guest Formula and its operator will not be liable for indirect, incidental, special, consequential or punitive damages, or for losses arising from reliance on an estimate, purchasing decisions, food handling, dietary issues, alcohol service or inability to use the site.

These terms may be updated as the site changes. Continued use after an update constitutes acceptance of the revised terms. If you do not agree, do not use the site.
