Catering Business Calculator

Catering economics work per event rather than per month. Each booking brings in a number of guests at a price, spends food money on every one of them, and carries a labour bill that barely moves with headcount. What survives is that event's contribution, and the month's fixed costs come out of the total. At the defaults below, one event contributes 4,000: 100 guests at 75 leaves 5,500 once 20 a head of food is taken off, and 1,500 of labour takes it to 4,000.

Which makes the fixed costs look small, and at this size they are. 5,000 a month is covered by 1.25 events, and the remaining 6.75 bookings account for the whole result: 6.75 multiplied by 4,000 is exactly the 27,000 the calculator returns. It also explains why catering swings so hard when bookings thin out. The same 5,000 against two events a month is a different business.

Two things go wrong most often, and they cost about the same. Underpricing is the first: drop price per guest from 75 to 60, a 20% discount, and profit falls from 27,000 to 15,000. Labour underestimation is the second. A head chef at 400, two sous chefs at 200 each, six servers at 100 each and a 200 setup and cleanup crew comes to 1,600 for a single event, already above the 1,500 the defaults assume, and travel, transport and overrun push it higher. At 3,000 an event the same eight bookings return 15,000 instead of 27,000.

Quick example

With events per month of 8 and avg guests per event of 100 (plus price per guest of 75 and food cost per guest of 20), the result is 27,000.00.

Revenue is 60,000. Food takes 16,000, and labour of 12,000 alongside fixed costs of 5,000 make up the 17,000 the result card shows as Labour + Fixed, leaving 27,000 at a 45% net margin. That is a high-ticket scenario running at full booking, not a typical month.

Which inputs matter most

You enter Events per Month, Avg Guests per Event, Price per Guest, Food Cost per Guest, Labour Cost per Event, and Fixed Costs Monthly.

Guest count and price are the sharp ones, because the gap between them is what every guest contributes and labour does not shrink to match. Halve guests to 50 and profit falls from 27,000 to 5,000, since the 1,500 of labour still turns up for a smaller room. Events per month is gentler once fixed costs are covered: four bookings rather than eight return 11,000, not the 13,500 a straight halving would suggest, because the 5,000 of fixed costs does not halve with them.

What's happening under the hood

Revenue is events multiplied by guests multiplied by price. Food is events multiplied by guests multiplied by food cost per guest. Labour is events multiplied by labour per event. Profit is revenue minus food, labour and fixed costs, and net margin is that profit over revenue.

The model treats labour as a flat cost per event, which is close to how catering actually staffs but not exact, since a 300-guest booking needs more servers than a 60-guest one. Food cost per guest is held constant, so bulk purchasing on larger events does not show up. Nothing here covers waste or spoilage, travel and transport, deposits and cancellations, tax, or seasonality, and a single month read in isolation will mislead in a trade where bookings cluster. The one figure worth carrying away is the contribution each event makes after its own food and labour: at the defaults that is 4,000, and fixed costs are simply how many of those a month has to absorb.
