How plate costing works

A plate cost is the price of everything the customer eats, divided into one serving. You list each ingredient in the recipe, multiply the amount used by what you pay per unit, add the lines up for a whole batch, and split the batch across the plates it produces.

Menu cost per serving = (quantity of each ingredient x unit price you pay, adjusted for yield) all added together, times a waste factor, divided by servings per batch.

Run a batch of 10 tomato pasta plates as an example. The ingredients below cost $32.00 before any allowance for trim or staff meals. Divide by 10 plates and the plate sits at about $3.20 before waste, or $3.36 once you carry 5 percent for boots in the pot luck, dropped plates and the cook's dinner.

That $32.00 batch with 5 percent waste across 10 plates gives a plate cost of 32.00 x 1.05 / 10 = $3.36. Every pricing decision in the rest of this page hangs off that one number, which is why the recipe sheet, not the invoice, is where menu profit is won or lost.

Yield: you pay for bones, peels and trim

The number on the invoice is the as-purchased price, but the customer eats the edible portion. A whole chicken does not arrive as boneless skinless breast. Onions shed skins, pineapples lose a crown and rind, and beef brisket shrinks in the smoker. Yield, sometimes called the edible yield or yield factor, is the share of what you buy that ends up on the plate.

Cost per usable unit = as-purchased price / yield. If a whole chicken costs $2.30 per pound and breaks down to 65 percent usable cooked meat, the true cost is 2.30 / 0.65 = $3.54 per usable pound. A recipe calling for half a pound of cooked chicken carries $1.77 of bird, not the $1.15 the invoice suggests.

The tenderloin row is the one that hurts. Trim and silverskin push the working price up by more than a third, and kitchens that price from the invoice rather than the yield sheet price steaks below cost without noticing. Weigh the waste once, write the yield down, and reuse the number until the cutting spec changes.

Staff meals, waste and the batch math

Food leaves the kitchen without earning revenue. Cooks eat, trays come back, hollandaise breaks, and the till never sees it. Industry practice folds this into a waste percentage applied on top of the recipe cost. Five percent is a common planning figure for a disciplined kitchen; a sloppy one can run double that, and the menu pays for it.

Plate cost = batch ingredient cost x (1 + waste percent) / servings per batch.

The tomato pasta batch shows the whole chain. Ingredients cost $32.00. Add 5 percent for staff meals and spoilage: 32.00 x 1.05 = $33.60. Split across 10 plates: 33.60 / 10 = $3.36 per plate. If you only get 9 sellable plates because one went back, the same food now costs $3.73 per plate, and the menu price that targeted a 28 percent food cost quietly becomes 31 percent.

Three habits keep this line honest:

• Count servings as plates that sell. If the batch yields 10 but one is spoken for, use 9.
• Log staff meal separately for a week. If it runs 2 percent of purchases, carry 2 percent, not a round 5.
• Re-weigh after a recipe change. A new portion scoop moves the batch total and everything downstream of it.

Pricing the plate with a target food cost percentage

With the plate cost in hand, pricing is one division. Target menu price = plate cost / target food cost percentage. Food cost percentage is the share of the menu price that the ingredients consume, and the gap between them is the gross margin on the dish.

Most successful restaurants spend no more than 28 to 35 percent of the menu price on ingredients, according to restaurant management guidance published by Johnson & Wales University. Culinary school benchmarks from Escoffier School of Culinary Arts place the healthy band at the same 28 to 35 percent, with labor at 25 to 35 percent and net profit at 5 to 10 percent.

The $3.36 pasta plate priced at four common targets:

Ten points of target, from 25 to 35 percent, moves the price from $13.44 to $9.60. That sensitivity is why the target is a business decision, not a formula output: a neighborhood pasta house competing on price picks 32 percent and charges $10.50, while a wine bar with the same plate picks 26 percent and charges $12.95 without losing the table.

What food cost percentage leaves out: labor, rent and true contribution

A 28 percent food cost does not mean the dish keeps 72 percent. Payroll, rent, utilities and card fees all come out of that gap before anything reaches the bottom line. The money left after food, labor and a share of overhead is the contribution margin, and it is the number that tells you whether a dish earns its spot on the line.

Contribution per plate = menu price - plate cost - labor per plate - overhead per plate. Overhead per plate is your monthly rent and fixed costs divided by the covers you do.

Take the pasta at $12.00: food $3.36, direct labor $3.20 a plate, and a storefront running $9,600 a month over 3,000 covers, which is $3.20 a plate. Contribution is 12.00 - 3.36 - 3.20 - 3.20 = $2.24, or 18.7 percent of the price. The 72 percent gross margin was true, but the dish keeps less than a fifth of it.

Ingredient inflation pushes the other way. The Bureau of Labor Statistics reported the food away from home index up 3.5 percent over the 12 months ending September 2026, with full service meals and snacks up 3.8 percent (BLS CPI, September 2026). The USDA Economic Research Service forecasts food away from home prices up 3.5 percent for 2026 in its October 2026 Food Price Outlook. A menu priced in 2024 quietly absorbs that drift until someone reruns the recipe sheets.

Menu engineering: the four quadrants

Cost and price are only half the story; sales volume is the other half. Menu engineering plots every dish on two axes, popularity against margin, and sorts the menu into four boxes. A dish with a 72 percent margin that nobody orders earns less than a 60 percent margin dish that walks out the door all night.

The quadrants talk to each other. Dropping two dogs frees prep time and cooler space for a second star. A plowhorse like the burger can fund a puzzle's marketing, because the burger's volume carries fixed costs that let the kitchen keep an 80 percent margin dish alive at low volume.

A second worked example: the cheeseburger

The burger shows where yield bites. Ground beef loses moisture and fat in cooking, so the patty you price is not the pound you bought.

The beef line is the tell: 5.0 lb x $4.90 = $24.50 on the invoice, but at 90 percent yield the kitchen needs 24.50 / 0.90 = $27.22 of beef per batch of patties. The adjusted batch totals $45.87, and with a 5 percent staff meal and waste allowance across 12 plates the plate cost is 45.87 x 1.05 / 12 = $4.01.

At a 30 percent target the formula says $13.38, so the menu prints $13.50, which puts the real food cost at 4.01 / 13.50 = 29.7 percent. Side by side with the pasta:

The burger has the higher food cost and the lower margin, yet it contributes $0.55 more per plate because of its price point. Margin percentage and contribution dollars disagree, and the till takes dollars.

When to reprice and what the model misses

Johnson & Wales guidance recommends revisiting the menu at least once a year, and sooner when a key input jumps. A practical trigger list: beef or dairy up more than 10 percent since the last costing, a new distributor contract, a rent renewal, or a food cost report running a full point above target for two months straight. Rerun every recipe sheet in an afternoon using the calculator above; the plates that moved more than a quarter get repriced, the rest wait.

The model on this page has known edges:

• It prices one plate, not the menu. A 30 percent average with a 45 percent steak still loses money on that steak if the side dishes that offset it sell badly.
• Labor is entered as a flat per-plate figure. Real kitchens spread salaried staff across everything, so the per-plate labor number is an allocation, not a measurement.
• Prices are a snapshot. With USDA ERS forecasting a 3.5 percent rise in food away from home prices for 2026, a costing done in January drifts by year end.
• Sales mix is missing. Menu engineering needs order counts, which come from your point of sale, not from a recipe sheet.

Used with those limits in mind, plate costing turns menu pricing from a guess into a spreadsheet you can defend, and the four quadrants tell you which plates deserve the next round of attention.
