- Cost per guest

- Food and drinks (incl. service)

Food and drinks: 50 × ($20 + $8) = $1,400.00
Fixed: $150 cake + $300 rentals + $0 venue + $150 other = $600.00
+ 10% cushion = $2,200.00, or $44.00 per guest
- Fixed costs work out at $12 per guest. They do not shrink when guests cancel, so they weigh more on a small party.

A party budget has two kinds of cost. Per-guest costs — food, drinks, plates, favors — grow with every name on the list. Fixed costs — the venue, the tent, the DJ, the cake table, decorations — barely change whether thirty or sixty people come. This calculator keeps them apart, so you can see which lever moves the total.
How the calculation works
food & drinks = guests × (food + drinks per guest) × (1 + service charge) fixed = cake + rentals + venue + other total = (food & drinks + fixed) × (1 + cushion) cost per guest = total ÷ guests
The prices already filled in are examples to show how the math works, not typical costs where you live. Replace each one with a real quote, a menu price or your grocery list. Catering quotes are often written per person, with a service charge, gratuity or tax added on top; ask exactly what the per-person price includes before you compare two caterers.
Working out the per-guest numbers
If you are cooking yourself, the per-guest food cost is easiest to build from a shopping list. Use the quantity calculators — food per person, meat per person, side dishes and drinks — add each result to the project list, price the list, and divide by the guest count. Drinks include ice, coffee and soft drinks as well as anything from a bar.
Ways to bring the total down
- Guests first. Every guest you cut saves their whole per-guest cost, and at a catered event that is usually the biggest single figure.
- Time of day. A brunch, lunch or dessert reception needs less food and drink than a dinner party, and an afternoon party ends before people expect a second meal.
- Serving style. A buffet or family-style meal needs fewer staff than a plated dinner; a grazing table or heavy appetizers can replace a meal entirely.
- Rentals. Count tables and chairs carefully with the table calculator — renting ten too many is money for nothing. Borrowed folding tables with floor-length tablecloths look the same as rented ones.
- The cushion. Keep it. Something always costs more than planned, and 10% is a reasonable allowance for a small event.

Frequently asked questions
How do I work out party cost per person?
Add every cost — food, drinks, cake, rentals, venue, decorations and supplies — and divide by the number of guests. Keep per-guest and fixed costs separate so you can see what changes when the guest list does.
Why does a small party cost more per person?
Because fixed costs — a venue, a tent, a DJ — are shared among fewer people. A $600 tent adds $20 per guest at thirty guests and $6 at a hundred.
Should I add a contingency to a party budget?
Yes. Ten percent is a reasonable cushion for small events: extra ice, a forgotten serving utensil, a last-minute guest. If you do not spend it, you are under budget.
Are the prices on this calculator real costs?
No. They are examples to show how the math works. Prices vary widely by region and season, so replace them with your own quotes or shopping list.
