Plan wedding reception food and beverage quantities from attendance, service duration, servings per guest, and a practical contingency allowance. The calculator converts the guest plan into total servings, reserve servings, and hourly service demand so caterers can order with a transparent buffer instead of relying on a vague head-count multiplier.
The totals include the selected contingency and are rounded up to whole servings. They are planning quantities; menu composition, guest ages, dietary needs, weather, and service style can change actual demand.
Planning estimate only. Confirm vendor terms, contracts, venue rules, accessibility requirements, and local safety limits before committing.
For 180 attendees, 2.5 food servings and 3 drinks each, a 10% allowance produces ceil(495) = 495 food servings and ceil(594) = 594 drinks.
Choose a percentage that reflects RSVP certainty, vendor policy, menu flexibility, and the cost of shortages; the calculator does not prescribe a universal rate.
Yes, if they will receive the same catering. Otherwise add their meals as a separate line in the vendor order.
Not necessarily. A serving may be a course, tray portion, snack, or meal depending on how you define the input.
Catering cannot usually be ordered in fractional servings, so the calculator rounds the final quantity upward.
No. It affects the hourly drink-demand output, while food and drink totals come from per-guest assumptions.
