See what your party really costs

Party budgets have a way of creeping up long after you have booked the venue. A little more on food here, an extra round of drinks there, and suddenly the friendly get-together costs twice what you pictured. This calculator adds up your five main spending buckets — food, drinks, decorations, venue, and everything else — and shows the total alongside the number that actually matters when you are comparing plans: the cost per guest.

Why cost per guest is the number to watch

Per-guest cost is how caterers, party planners, and venues quietly price everything, and it is the fastest way to sanity-check a plan. Once you know you are spending, say, $28 a head, it is easy to decide whether trimming the guest list, swapping the menu, or moving the venue is the smartest cut. The tool also flags your biggest single category so you know where the money is really going before you commit.

How to use it

Enter the number of guests you expect to attend.
Type an estimate into each cost box — food, drinks, decorations, venue, and other.
Leave any category at zero if it does not apply to your event.
Read your total budget, cost per guest, and biggest expense — they update live as you type.
Adjust the numbers to test cheaper or fancier versions of the same party.

These figures are planning estimates to guide your decisions, not professional financial or catering advice — always confirm real quotes before you book.

FAQ

What should go in the "Other" box?: Use it for costs that do not fit the main categories — cake, entertainment, party favors, rentals, staff tips, or a cushion for last-minute extras.
How many guests should I count?: Use the number you actually expect to show up, not everyone invited. A good rule is to assume roughly 10 to 20 percent of invitees will decline.
Does it save my numbers?: No. Everything runs in your browser and nothing is sent anywhere or stored, so your budget stays completely private.
Can I use it for weddings or corporate events?: Yes. The five categories cover most events; just fold specialized costs like a photographer or DJ into the "Other" field.
