Break-Even on a Catering Order: Price the Job, Not Just the Plate

Why food cost percentage fails on catering

A restaurant plate carries a share of rent, utilities and service labour that is already paid for by the dining room. A catering job carries a block of costs that exist only because you accepted it:

Those costs do not scale with the guest count, which is why a thin per-plate margin can still leave a job unprofitable. Price the job as a job.

• Prep hours on a day the kitchen is already busy.
• Transport and the staff time consumed by it.
• Disposables, chafing fuel, foil and serving equipment.
• Setup and teardown at the venue.
• The delivery window, which can consume the labour of a manager for hours.

Build the job cost stack

Separate variable costs from fixed job costs, and be explicit about both.

Variable, per guest:

Fixed, per job:

Then apply two formulas:

contribution per guest = price per guest − food and disposable cost per guest

break-even guests = fixed job costs ÷ contribution per guest

And to find the price that hits a target margin:

minimum price per guest = (fixed job costs + variable cost per guest × guests) ÷ (1 − target margin) ÷ guests

• Food cost per guest, costed from your recipes at current invoice prices.
• Per-guest disposables and serving items.
• Any per-guest rental or venue charge.
• Prep labour hours, including packing.
• Transport: fuel, mileage or driver cost, plus parking.
• Disposables bought by the job rather than by the guest: chafing dishes, foil, labels, containers.
• Setup and teardown hours, including travel time.
• Administrative time: quoting, planning, ordering, confirming.
• An overage or spoilage allowance for a production batch cooked larger than the confirmed count.

Worked example: a 100-guest job

The numbers are illustrative, with a 35% target margin on the job.

The job is viable at $22.00. It becomes fragile if the guest count drops below about 35, or if food cost per guest rises while the price stays fixed.

• Break-even guest count: $468 ÷ $13.60 = 34.4, so 35 guests. Below that, the job does not cover its own costs.
• Revenue at 100 guests: $2,200. Total costs $468 + $840 = $1,308. Contribution: $892, or 40.5% of revenue.
• Minimum price per guest for a 35% margin at 100 guests: $1,308 ÷ (1 − 0.35) ÷ 100 = $20.12.

Test the two variables that move most

Guest count and food cost per guest decide most catering outcomes. Sensitivity-test them before you quote, not after the job.

A $1.00 move in food cost per guest shifts the break-even count by four to five guests at this price. If you are quoting close to the break-even line, a single price increase on a protein can turn a profitable job into a flat one.

Set a decline threshold

The most valuable number in catering is the one that makes you say no. Write a decline rule and apply it before you quote:

Then quote with a clear structure: price per guest, inclusions, minimums, a confirmed headcount deadline, and a policy for additional guests. Ambiguity at quote time becomes a dispute at drop-off.

• Decline below the break-even guest count unless the job is strategic in a way you can name and pay for.
• Decline below the minimum price per guest that hits your target margin, unless you can remove a fixed cost instead of cutting the price.
• Decline jobs that consume a peak service window without paying for the replacement labour in the dining room.
• Decline same-day changes that require re-purchasing product without a change-order fee.

Limitations and assumptions

• Labour estimates are estimates. If prep runs long or setup takes three trips, the fixed costs grow while the price does not.
• Overtime and weekend premiums can materially change the labour line; include them if the job requires hours that are already near full-time.
• Food cost uses current invoice prices. Seasonal and market volatility means a quote for a future date carries risk, which is one reason a confirmed-count deadline and a reasonable validity window matter.
• Transport costs depend on distance, vehicle and local fuel prices, and a multi-stop route can double the hours.
• This analysis covers job profitability, not financing, deposits or tax treatment. Payment terms, deposits and cancellation fees are commercial decisions that belong in the contract.
