All-in vs per guest

People quote both. All-in ($5,060) is money to have on hand for a milestone anniversary reception. Per guest ($127) is for comparing catering menus or grocery lists. This page does not add a third “average.”

What would change your number

  • A different guest count
  • A nicer or simpler catering
  • A quote you already have from a vendor

Change those amounts on the calculator — do not add a mental extra percent on top of Extra buffer.

Not in this number

  • Guest gifts and the host's outfit
  • Travel
  • Sales tax if a vendor puts it on the invoice

How to use the calculator

  1. Enter how many guests you are hosting. This example starts at 40.
  2. Open a cost row and tap a starting-price button, or type the quote you already have.
  3. Tap Calculate. The all-in and per-guest figures update together.
