Plate Cost Calculator
A plate cost calculator adds up every component on a single plate - protein, sides, sauce and garnish - plus a small waste allowance, to give the true cost of the dish and its food cost percentage at your current menu price. Enter each component's cost and see whether the plate hits your target margin.

Plate cost vs recipe cost
They're related but not the same. A recipe cost is the cost of a batch - a pot of sauce, a tray of roasted vegetables - usually divided into servings. A plate cost is what actually goes on one guest's plate as it leaves the pass: a portion of protein, a scoop of the side, a ladle of that sauce, and the garnish.
Most real dishes are built from several recipes plus à la carte items, so the plate cost is the sum of those portions rather than a single recipe divided up. That's why this tool lets you enter components directly - protein $9.35, sides, sauce, garnish - instead of a full ingredient list.
Use the recipe cost calculator to price each component batch, then bring those per-portion costs here to assemble the finished plate and check its food cost percentage against the menu price.
Worked example: steak plate
Take a steak main built from four components:
- Steak (8 oz portion): $6.50
- Potato side: $1.10
- Vegetables: $0.95
- Sauce & butter: $0.80
That's a raw plate cost of $9.35. Add a 5% garnish, waste and packaging allowance and it becomes about $9.82. At a menu price of $32, the food cost is $9.82 ÷ $32 ≈ 30.7% - comfortably inside a typical target range.
Change the menu price to $28 and the food cost jumps to about 35%; drop the steak portion cost and it falls. The calculator recomputes the percentage as you adjust each component, so you can see exactly which part of the plate is moving your margin.
Garnish and waste allowance
Even a carefully costed plate loses a little to things that are hard to portion exactly: the herb garnish, the drizzle of oil, the bread that comes alongside, the occasional remake, and packaging for takeaway. A small waste allowance - often around 3-8% - captures that so your plate cost isn't optimistic.
It's better to build a modest allowance in than to discover at inventory that your real food cost is a few points higher than your plated maths suggested. The allowance also cushions minor portioning drift on a busy service.
The calculator adds your chosen allowance percentage on top of the summed components before working out the food cost. Set it to match what your own waste tracking shows; if you don't track it yet, 5% is a reasonable starting point to refine later.
