How much does a luau cost? A 40-guest example (2026)
For example, a backyard luau for 40 guests typically costs about $790 all-in ($20 per guest), including Extra buffer.
That total is about $0 for the yard, $80 for the pulled pork, $240 for the island sides, $220 for the tiki drinks, $60 for the leis, $60 for the tiki torches, $50 for the paper goods, $0 for the invitations, and $80 for Extra buffer.
Extra buffer is spare money on top if something runs over. It is already inside that $790. This example is a backyard luau. It is not a destination Hawaii wedding, and it is not a simple backyard BBQ.

All-in vs per guest
People quote both. All-in ($790) is money to have on hand for a backyard luau. 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 island sides
- 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
If you need a tent, tables, or chairs, those are separate rental calculators -- not part of this $790.

- Enter how many guests you are hosting. This example starts at 40.
