All Party Calculators

How to pick the right calculator

There are four ways to start, and the best one depends on what you already know. If you have settled on a dish, use a food calculator like pizza and let it scale to your headcount. If you only know your guest list, start from a party size page and build the menu outward. Watching your spend? A budget calculator works backward from a dollar amount.

Every tool runs the same simple math: a typical per-person serving multiplied by your guest count, then rounded up so nobody goes hungry. Adjust for appetite, time of day, and whether other dishes share the table, and the numbers update with you.
