How much does a housewarming cost? A 25-guest example (2026)
For example, an open-house housewarming at the new home for 25 guests typically costs about $500 all-in ($20 per guest), including Extra buffer.
That total is about $0 for the home, $250 for the finger food, $150 for the drinks, $30 for the paper goods, $30 for the flowers / welcome, $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 $500. This example is an open-house housewarming at the new home. It is not a realtor staged open house, a sit-down dinner for 8, or a hotel welcome party.

All-in vs per guest
People quote both. All-in ($500) is money to have on hand for an open-house housewarming at the new home. Per guest ($20) 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 finger food
- 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
