Food cost percentage for caterers: the 28–35% rule

If you only remember one number in this business, make it this one: your food should cost about 28–35% of what you charge. Get that right and most other pricing problems solve themselves. Here's what the rule means, how to run it on a real plate, and what to do when your number lands outside the band.

The rule, in one line

Food cost percentage = ingredient cost ÷ menu price.

Multiply by 100 to get a percentage. If a plate costs you $9 in ingredients and you charge $30, that's:

$9 ÷ $30 = 0.30 → 30% food cost. Right in the pocket.

Most caterers aim to keep that figure between 28% and 35%. Below 28% you either have great buying power or your portions are getting thin. Above 35%, the food is eating your profit and you'll feel it at the end of the month even when the calendar looks full.

To go the other way — from cost to price — divide instead of multiply:

Price = ingredient cost ÷ target food-cost %.
$9 ÷ 0.30 = $30 per plate.

That single division is the fastest honest price you can quote.

Why 28–35%, and not lower

New caterers sometimes ask why they can't push food cost down to 20% and pocket the difference. Two reasons.

First, catering isn't a restaurant with a fixed menu and repeat volume. You're buying for one event, often at retail or near-retail prices, sometimes with specialty items and always with waste built in. Squeezing food cost too hard usually shows up as skimpy portions, and portions are the one thing clients and their guests actually judge.

Second — and this is the part that sinks people — food is not your only cost. The 28–35% band exists precisely because it leaves room for the other lines:

• Labor: your prep hours and service hours. For catering, labor commonly runs another 25–35% of the price.
• Overhead: insurance, packaging, fuel, software, licenses, the phone.
• Profit: what's left, and the reason you're doing this.

Food and labor together are your prime cost, and for most catering jobs prime cost lands somewhere around 55–65% of the price. Overhead and profit share the rest. If food alone is already at 45%, there is no math left over for you.

How to calculate food cost on a real plate

Don't estimate — build it from ingredients. For one serving of one dish:

1. List every ingredient, with the quantity that actually goes on the plate.
2. Price each at what you paid, converted to the unit you use (per ounce, per each, per cup).
3. Add them up. That's your plate food cost.
4. Add a small allowance for waste and consumables if you don't already (trim, spills, sternos, foil).

Worked example — a pulled-pork buffet plate:

At $4.00 food cost, here's what different prices do to your percentage:

• Charge $12 → 33% food cost. Healthy.
• Charge $10 → 40% food cost. Tight — check your labor still fits.
• Charge $16 → 25% food cost. Room for staffing or a richer menu.

What to do when the number is too high

Your plate comes out at 42% food cost. Don't panic, and don't just slash portions. Work the levers in order:

• Reprice first. If 42% is the honest cost, the price may simply be too low. Raise it. A pulled-pork plate at $12 instead of $10 moves you from 40% to 33% and no guest notices.
• Swap the cost driver. One or two ingredients usually drive most of the cost. Chicken thighs instead of breasts, a seasonal vegetable instead of an out-of-season one, a house sauce instead of a bottled specialty.
• Right-size the portion. Not thinner — accurate. Many caterers over-portion out of fear. A measured 5 oz protein instead of an eyeballed 7 oz is both cheaper and more consistent.
• Buy differently. Case pricing, a restaurant-supply membership, or a different vendor can move food cost several points on high-volume items.

Reprice before you touch the plate. The client is buying an experience, and thin portions cost you the next referral.

Food cost is the start, not the finish

The 28–35% rule gives you a fast, defensible price. But a real quote also has to carry your labor and overhead, and those are the lines caterers most often forget (see Catering labor cost: the % solo caterers forget). Once you know your food cost, the honest next question is: does the price also pay me for the day? If you want to see where a whole job's money actually goes, walk one through the breakdown (see What a $2,500 catering job actually costs).

And when the inquiry is for a headcount, not a single plate, the same math scales up cleanly (see How much to charge for catering for 50 guests).

Run your own plate

Reading about the rule is one thing; seeing your real margin is another. Drop your ingredient cost, labor %, and overhead % into the calculator and it returns your food-cost percentage and a suggested price — built on the same costing math as CaterKit, so there's zero drift between the tool and a real quote.
