How to use this tool

1
Enter the guest count

Type how many people are coming.

2
Set donuts per person

1.5 per person is a common party figure; use 1 for a light snack and 2 for a donut-focused event.

3
Add a buffer

A 10% buffer covers late guests and big appetites without much waste.

4
Read boxes and cost

Donuts are rounded up to whole dozens, since bakeries sell by the box.

Formula & worked example

Donuts needed = round up (guests × donuts per person × (1 + buffer)). Dozen boxes = round up (donuts / 12). Cost = boxes × price per dozen.

24 guests at 1.5 donuts each need 36 donuts, or 3 dozen boxes; at $12 a dozen that costs $36.

Limitations — read this before you rely on it

This is a planning guide, not a guarantee: appetite, time of day, other food and dietary needs all change how many donuts are actually eaten.

Twelve, though some bakeries add a thirteenth — the baker’s dozen — so ask when ordering.

Order a small separate box of gluten-free or vegan donuts if any guests need them, rather than guessing from the main count.

They are best the same day; store leftovers airtight at room temperature and eat within a day.
