How the Party Food Calculator works

Enter the guest count, how hungry they will be and how long the event runs.

The calculator applies common caterer rules of thumb per person.

Round up and add a small buffer for events with big eaters or no other food.

The formula

Protein = guests × 0.5 lb × appetiteSides = guests × 0.75 lb × appetite

Worked example

Using the default values shown in the calculator:
