Catering quotes are famous for looking like one number and arriving as another. The menu price you negotiated per person is almost never the bill you actually pay. On top of the food charge, caterers add a service fee or gratuity, pass through sales tax on prepared food, and tack on flat delivery and setup or rental charges. By the time the invoice lands, a quote of $45 per head can easily feel like $54 or more.
This catering cost calculator takes the per-person menu price and rebuilds the full event bill the way a caterer actually prices it: food and beverage first, then service fee, then tax, then the flat extras. The result card shows you the food total, the service fee, the tax, the delivery-and-setup line, the all-in cost per guest, and the grand total — so you can compare two caterers on a true per-head basis instead of comparing apples to their marketing headline.
How to Use
- Enter the Number of Guests — the confirmed or expected headcount you are feeding. If you are still planning, use your best estimate; most caterers require a guaranteed count about 72 hours before the event.
- Set the Cost per Person (Food & Beverage) — the caterer's quoted per-head menu price before any fees. This is the headline number on most proposals.
- Set the Service Fee / Gratuity. The industry norm is 18%–22% of the food total. Treat it as a separate line: a "service charge" is not the same as a discretionary tip, and it is rarely optional.
- Add the Sales Tax if your locality taxes prepared food (most do, at roughly 6%–10%). In many states, tax is applied to the food total and sometimes to the service fee too; this calculator applies tax to food plus service fee, which matches the common invoice structure.
- Enter flat Delivery Fee and Setup / Rental Fee amounts if the caterer quoted them separately. These are the line items most often forgotten when people mentally multiply "guests × per-person price."
- Read the result card. The highlighted Total Catering Bill is what you will actually pay, and the All-In Cost per Guest is the honest number to compare against other quotes.
How Catering Prices Actually Build Up
Underneath every quote is a simple stack. The food charge is just the bottom layer:
- Food & Beverage Total = Number of guests × cost per person.
- Service Fee / Gratuity = Food total × service fee percent. This covers waitstaff, chefs on site, and overhead; it is normally 18%–22%.
- Sales Tax = (Food total + service fee) × tax percent. Rules vary by state — some tax only the food, some tax the service fee as well.
- Delivery + Setup = flat charges for transport, arrival, table, linen, and equipment setup.
- Total Catering Bill = food + service fee + tax + delivery + setup.
- All-In Cost per Guest = total bill ÷ guests.
Worked example on a 100-guest event at $45 per person with a 20% service fee and no tax or extras: food is $4,500, the 20% service fee adds $900, and the grand total is $5,400 — which comes out to $54 per guest, not the $45 you started with. That $9 difference is why comparing headline per-person prices misleads so often.
Examples
Example 1 — The baseline wedding or corporate lunch. 100 guests at a $45-per-person buffet, 20% service fee, no separate tax or flat charges. Food = $4,500; service fee = $900; total = $5,400; all-in cost per guest = $54. If a second caterer quoted $52 per head with a 22% service fee and a $500 setup charge, run that through the calculator to see which is genuinely cheaper once fees are layered on.
Example 2 — A taxed event with delivery and setup. 150 guests at a $60-per-person plated dinner, 20% service fee, 8% sales tax, $250 delivery, and a $500 setup/rental fee. Food = $9,000; service fee = $1,800; tax on ($9,000 + $1,800) at 8% = $864; extras = $750; grand total = $12,414, or about $82.76 per guest. Notice how the $60 headline becomes $82.76 once everything is included.
Example 3 — Budget-conscious backyard party. 50 guests at a $20-per-person drop-off buffet, no service fee, no tax, no delivery. Food = $1,000; total = $1,000; per guest = $20. Drop-off catering skips the service-fee layer, which is why it can cost less than half per head compared with fully staffed service.
FAQ
How do I calculate catering cost per person?
Multiply the number of guests by the per-person menu price to get the food total, then add the service fee (usually 18%–22% of food), sales tax (often 6%–10%), and any flat delivery or setup fees. Divide the grand total by the guest count to get the true all-in cost per guest. This calculator does that build-up for you instantly.
What is a typical service fee for catering?
Most caterers charge a service fee or gratuity of 18%–22% of the food and beverage total. A 20% service fee on a $4,500 food order is $900. Be aware that a mandatory service charge is different from an optional tip, and in many venues it is added automatically whether or not you intended to tip.
How much does catering cost for 100 guests?
For a typical buffet at $45 per person with a 20% service fee, 100 guests costs about $5,400 total. Add sales tax and a delivery or setup fee and the bill usually lands between $5,500 and $6,500. Plated dinners and open-bar service push the per-person price higher, often into the $80–$150 range.
Is sales tax charged on catering?
In most US states, prepared food and catering are subject to sales tax, typically 6%–10%. Some states tax only the food charge, while others also tax the service fee. This calculator applies tax to food plus service fee, which matches the most common invoice structure; check your caterer's line items to confirm.
What is the difference between a service fee and a tip?
A service fee (or service charge) is a mandatory, non-negotiable percentage built into the contract, usually 18%–22%, and it goes toward staffing and overhead. A tip is a discretionary amount paid directly to staff at the end of the event. Do not double-pay: if a service charge is already on the bill, a separate tip is optional rather than expected.
Why is my catering quote higher than "guests times price per person"?
Because the headline per-person price is only the food layer. Caterers almost always add a 20% service fee, pass through sales tax on prepared food, and charge flat delivery and setup or rental fees. A $45-per-head quote commonly arrives as a $54-per-head bill once those layers are included — which is exactly what this calculator surfaces before you sign the contract.
