Food cost percentage, the short course

What plate cost actually means

Plate cost is what the ingredients on a plate cost you, at wholesale, before labor, rent, or anything else. If a burger uses a beef patty, a bun, cheese, and a few condiments, plate cost is the sum of what each of those items costs per portion.

It sounds simple because it is simple. The hard part is keeping the inputs current. Wholesale prices move week to week, and a menu priced against last quarter's dairy or egg numbers can drift out of line without anyone noticing until the P&L shows it.

Food cost percentage, the formula

Food cost percentage takes plate cost and compares it to what you charge:

Food cost percentage = plate cost ÷ menu price

If a dish costs $4.50 to plate and sells for $15, that's 30 percent. Flip it around and you can also solve for price: menu price = plate cost ÷ target percentage. Same arithmetic, different variable held fixed.

That's the whole pattern. Everything else on a spec sheet, plus-based pricing, contribution margin, ideal versus actual cost, is a variation on this ratio.

Target bands, by kitchen type

There's no single correct number. Different formats run different bands because their labor and volume structures are different:

• Casual and fast casual kitchens often work toward the high 20s to mid 30s percent range, since higher volume and simpler prep can absorb a slightly richer ingredient cost.
• Full service and fine dining kitchens tend to aim lower, often high teens to mid 20s percent, because labor, service, and lower turns carry more of the weight.
• Bar and beverage-driven menus sometimes let food run a bit higher if drinks pull the blended percentage back down.

These are starting points, not laws. A kitchen with tight labor and strong volume can run a higher food cost percentage and still hit its margin. The band is a planning tool, not a grade.

The two levers: portion and price

Once you know your target band, you only have two things to pull:

1. Portion. Change how much of an ingredient goes on the plate. A slightly smaller pour of cream sauce or a tighter cheese portion changes plate cost directly.
2. Price. Change what you charge. If wholesale costs move and portion is already tight, price is the remaining lever.

Most kitchens use both, in small moves, rather than one big swing. A menu that reprices everything at once looks reactive to guests. Small, regular portion checks against current wholesale numbers keep the ratio in range without a visible jump on the menu.

Where to run the numbers

The arithmetic here is easy by hand once you have current prices. The part worth automating is keeping those prices current. PlateCost pulls live USDA wholesale series, shell eggs, CME cash dairy, and Northeast cream, so the plate cost side of the equation reflects this week's market, not last quarter's.

Start with the plate cost calculator to build a dish from current wholesale prices, then check the ratio with the food cost percentage calculator against your target band. If a single ingredient is driving the swing, the egg price tracker and dairy price tracker show what moved and when.
