Planning estimates
Calculator results are estimates, not guarantees. Appetite, weather, event length, menu, age, glass size and many other factors change real requirements. Keep a sensible buffer where running out would matter.
Safety and allergens
Nothing on this site replaces product instructions or advice from a qualified professional. Check ingredients and cross-contamination risks directly. Follow Food Standards Agency guidance for storage, preparation, cooking and leftovers. Do not use an online plan to decide whether questionable food is safe.
Alcohol
Alcohol outputs are stock-planning estimates and not consumption targets. Provide water and appealing alcohol-free options, never pressure guests to drink, and never serve alcohol to anyone under the applicable legal age.
Intellectual property
You may print tool results for personal use and link to public pages. Republishing substantial site copy, templates, code or paid downloads requires written permission.
Digital products
Product-specific pricing, licence, delivery, support, refund and statutory cancellation information will be shown before any checkout is launched.
