Party Food Quantity Calculator
Planning a party? Estimate how much appetizer, main, sides, dessert, drinks and ice you need from your guest count and event type.
How it works
Each item = guests × per-guest amount for the event type · Drinks = guests × (hours + 1) · Ice = guests × 1.5 lb
Caterers plan by per-guest amounts that shift with the style of event. A cocktail party leans on many appetizers and little else, a buffet needs a solid main plus sides, and a plated dinner uses slightly less of everything because portions are controlled. Drinks track time rather than food: budget about two servings in the first hour and one for every hour after, which is where the "hours + 1" comes from. These are planning averages — heavy drinkers, all-day events or a crowd of big eaters push the numbers up, so round generously for staples that keep.
Worked example
You are hosting 20 guests at a 3-hour buffet. Appetizers at 6 pieces each is 120 pieces; main protein at 0.5 lb each is 10 lb; drinks at 20 × (3 + 1) = 80 servings; and ice at 1.5 lb each is 30 lb.
Frequently asked questions
How much meat should I plan per person?
For a buffet with sides, about half a pound of raw meat per adult is a safe estimate, dropping to roughly a third of a pound of cooked protein at a plated dinner. Bump it up for a meat-focused menu or big appetites.
How many drinks per guest?
A common rule is two drinks in the first hour and one per hour after, so a 3-hour event is about 4 servings per guest. Provide extra non-alcoholic options and round up — running out is worse than a few leftovers.
Should I add extra for leftovers or no-shows?
Plan for your confirmed count and add roughly 10% for shelf-stable staples and drinks, which keep. Avoid over-buying perishable mains; it is cheaper to top up appetizers and sides than to waste cooked protein.
