How much does a going-away party cost? A 20-guest example (2026)
For example, a farewell at home for 20 guests typically costs about $430 all-in ($22 per guest), including Extra buffer.
That total is about $0 for the home, $200 for the snacks, $120 for the drinks, $30 for the banner / decor, $20 for the farewell gift, $20 for the paper goods, $0 for the invitations, and $40 for Extra buffer.
Extra buffer is spare money on top if something runs over. It is already inside that $430. This example is a farewell at home. It is not a retirement party, and it is not a housewarming.

People quote both. All-in ($430) is money to have on hand for a farewell at home. Per guest ($22) 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 snacks
- 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

- Travel
- Sales tax if a vendor puts it on the invoice
