The per-head price is an output, not an input
Clients ask for a per-head price because it is the only number that lets them compare two caterers, and it is a terrible unit for building a quote. Of the six cost blocks in a typical event, exactly one scales cleanly with the head count. Rentals come in delivery minimums and crate quantities. Transport is a van and a driver regardless. Setup and breakdown hours are set by the site and the equipment, not by whether sixty or ninety people eat. Overhead is a share of a fixed annual number.
Build the sheet in dollars, add the margin, and divide at the end. The per-head figure that falls out is the one to quote, and it will move as the count moves in a way that a per-head build never captures. Quote the same menu at 60 and at 200 guests and the per-head price should differ substantially, because the fixed blocks are being spread over three times as many people.
Food cost per head in the menu block should be edible-portion cost, not invoice price. An event menu built around trimmed proteins is where the difference bites hardest, since a low yield on a main course multiplies through the entire guest count at once. Run the proteins through the portion yield calculator before they go in here, and build the component costs on the recipe cost calculator.
Door to door is the field that sinks quotes
The hours field asks for door to door because that is what you pay for, and it is routinely quoted at service hours instead. A three-hour dinner service for 120 guests is not a three-hour job. It is loading a van, driving, finding the service entrance, setting a kitchen that does not exist, staging, three hours of service, breakdown, loading out, driving back and unloading. Nine hours is not unusual, and a quote built on three is short by two thirds of its largest cost block after food.
Staff ratios are the other half of this and they depend entirely on service style. Plated service with wine, family style, a buffet with attended stations, and a drop-off with no service on site have completely different staffing, and any ratio quoted without the style attached is not information. The calculator shows guests per staff member so you can sanity-check what you entered against what the job actually requires, but the number that is right is the one your own experience of that style produces.
Whatever wage goes in the field, it is a wage you set. Overtime on a long event day, how event and on-call hours are treated, and every tipped-wage question are set by federal and state law and often by city ordinance, they differ sharply between states, and they change. The labour cost percentage calculator handles the same block for a regular schedule and takes the same position on it.
Guarantees, and who carries the count risk
The guaranteed minimum is the number the client commits to pay for regardless of who turns up, usually fixed some days before the event. It exists because you buy, prep and staff against a count and cannot unbuy any of it if fewer people arrive. Without a guarantee, the client can revise downward at will and every fixed cost in the quote lands on a smaller base.
The calculator bills on the larger of the guarantee and the guest count, and the scenario table shows what different turnouts do to the sheet. The important row is the one below the guarantee: revenue holds at the guaranteed count while the food cost holds too, because you already cooked it. That is the guarantee doing its job. Remove it and that same row shows revenue falling while every cost stays where it was.
| Term | What it does | Who it protects |
|---|---|---|
| Guaranteed minimum | Sets a floor on the billed count | You, against a short turnout |
| Final count deadline | Fixes the number at a date you can still buy against | Both, if the date is realistic |
| Overage handling | Says what happens if more arrive than the count | Both — silence here causes arguments on the night |
| Deposit and payment schedule | Funds the purchasing before the event | You, against carrying the whole cost |
What any of those clauses should say is a contract question rather than a costing one, and the contract guide covers the general shape of getting terms written down. The dollar consequence of each is what this page is for.
Margin, markup and overhead recovery
The margin field is a gross margin, meaning profit as a share of the price. Divide cost by one minus the margin to get there. It is not a markup, which is profit as a share of cost, and the two diverge fast: a 35 percent margin is a 53.8 percent markup, and a 50 percent margin is a 100 percent markup. Quoting a job at cost plus 35 percent when you meant a 35 percent margin leaves nearly a quarter of the intended profit on the table. The output shows both figures so the number you meant is visible.
Overhead recovery is separate from margin and has to be, because it is a cost rather than a profit. Your rent, commissary, insurance, vehicles, office and the time spent quoting jobs you did not win all have to be carried by the jobs you did win. Derive the percentage from your own annual figures: total overhead divided by total direct job costs across a year gives the rate to apply. Folding overhead into the margin instead is the classic way a busy catering year produces no money, because the margin looked healthy on every individual job while none of them were paying for the building. The same structure applied to trade work is on the job cost and markup calculator, and the plain margin against markup arithmetic is on the margin calculator.
What is not in this quote
No sales tax, because rates and what is taxable for prepared food and event services vary by state and often by locality, and catering is one of the areas where the rules are least uniform. No service charge or gratuity, because how those are handled, disclosed and distributed is regulated and differs between states. No alcohol, because licensing for off-premise service is its own subject and in many places requires a permit per event. No insurance beyond whatever you put in the other costs field, though venues frequently require a certificate naming them, and that has a real price.
Nothing on this page is a food safety judgement either. Transporting, holding and serving food away from your own kitchen is the part of catering with the most exposure and the least margin for improvisation, and what is required is set by your local health authority and by your own written plan. The food safety guide is an orientation to the subject and not a standard you can cater to. For working out how much food to buy for a crowd in the first place, the food per person calculator covers quantities.
Questions people ask
How much should I charge per head for catering?
The question cannot be answered from outside your own cost sheet, and any figure quoted as a general answer is describing a different event in a different market. The per-head price is your total cost divided by the billed count, then divided by one minus your margin, and every input in that chain is local: what you pay for product, what you pay staff, what rentals cost in your area, how far the venue is, and what your overhead is. Two caterers doing the same menu for the same count can be forty percent apart on cost and both be pricing correctly. Build the sheet, then compare the resulting per-head figure to what your market appears to bear, and treat a large gap as a question about your cost structure rather than about your pricing.
How much overproduction should I allow?
It depends almost entirely on service style, and this calculator asks rather than assumes. Plated service with a fixed portion needs the least, because the portion is controlled and the count is known. Family style needs more, since a table that empties a platter gets another one. Buffets need more again because guests serve themselves and the last person through has to see a full-looking display, which means food that will never be eaten. Passed items are the hardest to predict since consumption depends on how long the reception runs. Your own history is the best source: track what came back from the last dozen events by style and you will have a better allowance than any rule of thumb.
Should rentals be marked up or passed through at cost?
Both approaches are common and the difference matters more than it looks. Passing rentals through at cost keeps the quote transparent and easy to defend, but it means the time you spend specifying, ordering, counting in, counting out and settling damage claims is unpaid, and that time is real. Marking them up covers the handling but invites a client who priced the rental company directly to ask why your figure is higher. A middle position that some operators take is to pass the rental at cost and carry the handling in a coordination or management fee that is visible as its own line. Whichever you choose, the cost has to be in the sheet somewhere, because rentals are often the second largest block after labour.
What does the guaranteed minimum actually protect me from?
From carrying the whole fixed cost of an event on a smaller revenue base after you have already spent it. By the time a turnout is short, the food is bought and largely cooked, the staff are booked and will be paid, the rentals are delivered and the van has been driven. Almost none of that can be recovered. The guarantee sets a floor under the revenue that matches the floor already under your costs. Without one, the entire count risk sits with you, and the scenario table on this page shows the shape of it: costs flat, revenue falling, and the whole difference coming out of the margin. Whether a guarantee is normal in your market and what deadline it should carry is a matter for your contract.
Why is my catering margin worse than my restaurant margin on the same food?
Because the cost structure is different in a way the food cost does not show. A restaurant has a kitchen, equipment, storage and a dining room that already exist and are paid for by the rent. Catering rebuilds all of that on someone else site every time, and the rebuilding is labour, transport and rentals rather than food. It is normal for food to be a minority of a catering cost sheet where it is the largest single controllable line in a restaurant. That is also why a catering quote priced off the restaurant menu price loses money reliably: the menu price was set to cover a fixed-premises cost structure that the event does not have, and it does not cover the one the event does have.
