Cost Per Plate Calculator

Cost per plate (also called plate cost) is what a single serving of a finished dish costs you in raw ingredients. That means every component: protein, starch, vegetables, sauce, garnish, plus extras like condiments and waste (the Q Factor).

The formula: Plate Cost = ∑ Component Costs + Q Factor. For a fully loaded view, add labor and overhead. This differs from cost per serving, which starts from total recipe cost divided by portions. Plate costing builds up from individual components, giving you more granular control over where your money goes.

The Q Factor covers costs that aren't in the recipe itself: salt, pepper, cooking oil, condiments, bread baskets, butter, garnishes, disposables, and waste from overproduction. It typically adds 5-10% to your ingredient cost.

In sit-down restaurants, the Q Factor can reach $2-3 per plate. A bread basket alone costs $0.50-0.80 per cover. Olive oil for finishing, a side of ranch dressing, extra napkins — these invisible costs are why many operators underestimate their true plate cost. Track the Q Factor monthly and cut what guests don't notice.

Traditional plate costing only counts raw ingredients. But adding a labor allocation shows what a dish really costs to put out.

To estimate: divide your kitchen labor cost for a shift by the number of covers served. If your kitchen runs $800/shift and serves 120 covers, labor is about $6.67 per plate. Food cost + labor cost = "prime cost," which most restaurants keep under 60-65% of revenue. Use our restaurant labor cost calculator to track labor separately.

Benchmarks by restaurant type:

Pizzerias: 18-22%
Fast casual/QSR: 25-28%
Full-service casual: 28-32%
Fine dining: 30-35%

Above 35% and you're likely losing money on that dish — unless it pulls in high volume or drink orders that compensate. Not every dish needs to hit the same target. Balance high-cost items (steaks, seafood) with high-margin items (pasta, salads). For more on this, see our menu engineering guide.

Divide your total plate cost by your target food cost percentage (as a decimal). The formula: Menu Price = Plate Cost ÷ Target Food Cost %.

If a plate costs $16.97 and you want 35% food cost: $16.97 ÷ 0.35 = $48.49 minimum menu price. Round up to $49 and adjust for market positioning.

Our menu pricing calculator and selling price calculator automate this math. For more context on pricing strategy, see our food cost percentage formula guide.

Weekly or bi-weekly — every time supplier prices change. A 10% jump in protein price can wipe out your margin on several dishes at once.

At minimum:

• Re-cost your top 10 sellers monthly
• Re-cost all menu items quarterly
• Re-cost whenever you change suppliers, modify a recipe, or launch a seasonal menu

A dish that cost $5.50 per plate six months ago might cost $6.25 today. Without regular updates, your food cost percentage silently climbs.

Protein is usually the most expensive plate component. A yield test tells you the real cost per usable ounce:

1. Weigh the ingredient as-purchased (e.g. 10 lb whole chicken)
2. Butcher, trim, and cook as normal
3. Weigh the edible portion (e.g. 6.5 lb)
4. Calculate yield: 6.5 ÷ 10 = 65% yield
5. Calculate true cost: $3.00/lb ÷ 0.65 = $4.62/lb edible portion

Common yields: bone-in chicken 65%, whole salmon 60%, shell-on shrimp 50%, beef tenderloin 70%. Always cost recipes at edible portion price, not as-purchased price.

Recipe cost is the total ingredient cost for the entire batch — all portions combined. Plate cost is the cost for a single serving, built up from individual components on the plate.

A recipe cost calculator starts with a list of ingredients and quantities for a full batch. This plate cost calculator starts with individual plate components (6 oz protein, 4 oz starch, 3 oz vegetable) and adds the Q Factor. Both should arrive at the same number — if they don't, check your portion sizes against the recipe yield. The plate-level view makes it easier to spot which component is eating the most margin.
