Restaurant food cost is the ingredient spend behind a dish, expressed as a plate cost in dollars or as a percentage of its selling price. It starts with current supplier prices and realistic portions; on its own, the percentage does not show whether a dish also covers labor, order fees, or overhead.
The workflow is to cost each recipe, divide by realistic portions, choose a price using the item’s economics, then review contribution and sales mix. All examples use USD. Nommy’s free Recipe Cost Calculator and Menu Pricing Calculator handle the arithmetic, while a digital menu keeps published prices in sync.
Use food cost percentage as one check, alongside the dollars each sale contributes and how often the dish sells. This guide covers the math and the decisions that follow.
For the upstream menu-design work—category structure, pricing psychology, and live updates—pair this guide with our digital menu optimization guide. This guide focuses on the costing and pricing math underneath it.

What is restaurant food cost?
Restaurant food cost is the ingredient cost of a dish, expressed as a currency value (plate cost) or as a percentage of the selling price (food cost percentage). Plate cost shows what the portion costs to make; the percentage shows how much of its price goes to ingredients.
Prime cost reminder: Food cost covers ingredients only. Prime cost typically means food and beverage cost plus direct labor; packaging may be tracked separately or included depending on the restaurant’s accounting policy. It is an overall operating metric, not the same thing as a menu item’s food cost percentage.
Food cost percentage formula:
Food cost % = (Cost of ingredients ÷ Menu price) × 100
If a burger costs $4.20 in ingredients and sells for $14, its food cost percentage is $4.20 ÷ $14 × 100 = 30%. Read that ratio alongside the dollars left after ingredients, any other costs tied to the sale, and the item’s sales volume.
The mistake operators make is stopping at one dish. Restaurant food cost only becomes a management tool when you know it for every item on the menu, then weigh each item’s percentage against its sales volume. A dish at 40% food cost that sells 200 times a week matters far more than a dish at 20% food cost that sells twice.
Restaurant food costing at a glance
Food costing work moves from supplier invoices to a menu-level view:
In short: Cost every ingredient, divide the batch cost by saleable portions, then use a chosen food-cost target to calculate a starting price. Recheck the result against the price customers will pay, item contribution, and sales mix.
| Step | What you work out | Key formula | Decision check |
|---|---|---|---|
| 1. Recipe cost | Total ingredient cost for one batch | Sum of (ingredient qty × unit cost) | Are invoice prices and ingredients complete? |
| 2. Cost per serving | Ingredient cost for one plate | Recipe cost ÷ realistic portions | Does the yield match service? |
| 3. Menu price | Starting price from an item target | Plate cost ÷ target food cost % | Does the result fit the market and contribution plan? |
| 4. Menu performance | Contribution across items sold | Sum of (item contribution × units sold) | Which items contribute most across actual sales? |
Each step depends on the one before it. Incomplete ingredients or unrealistic portions make both the price and menu-level review unreliable.
How to calculate recipe cost step by step
Recipe cost is the foundation of restaurant food cost: the total cost of every ingredient that goes into a recipe, scaled to the quantity the recipe actually uses. The arithmetic is simple; the discipline is in tracking every ingredient—including oil, salt, garnishes, and the half-tablespoon of sauce operators tend to forget.
The recipe cost formula:
Recipe cost = Sum of (ingredient quantity × unit cost)
A step-by-step costing pass for one recipe:
- List every ingredient in the recipe, including oils, seasonings, and garnishes.
- Record the purchase unit and price from your latest supplier invoice—a 5kg bag of flour at $12, a 1L bottle of oil at $8.
- Convert the recipe quantity to the same unit as the purchase price. If the recipe uses 200g of flour and flour is bought by the kilo, that is 0.2kg.
- Multiply quantity by unit cost for each ingredient. 0.2kg × $2.40/kg = $0.48.
- Sum every line to get the total recipe cost for the batch.
- Apply a yield or waste factor if the recipe loses weight in cooking—peeled potatoes, trimmed meat, reduced stock. Cost the raw input, not the cooked output.
Two inputs need measurement rather than a guessed allowance: yield loss, which changes with ingredient and preparation method, and pantry staples such as oil, salt, and stock. Run a yield test for the ingredients actually used and record the small quantities that reach the plate.
The spreadsheet result is theoretical food cost: what the dish should cost when its recipe and portions are followed. Period-level actual food cost also reflects inventory changes, waste, spoilage, over-portioning, and unrecorded use. Comparing the weighted theoretical result with actual food cost can help locate a variance.
Use a restaurant inventory count sheet to keep the periodic stock count consistent, and a restaurant food waste tracker to record the avoidable loss behind that variance.
For the full breakdown of invoice-to-recipe unit conversions, yield factors, and the worked example for a multi-ingredient dish, see our guide on how to calculate recipe cost.
Recipe costing template: the free spreadsheet restaurants actually use
A recipe costing template repeats the same fields for each dish: ingredient, purchase unit and price, recipe quantity, line cost, batch total, portions, and cost per serving. Keep units consistent, include small ingredients, and update prices from supplier invoices so the sheet reflects current inputs.
For a downloadable, ready-to-use template plus the workflow for keeping it current as supplier prices move, see our free recipe costing template for restaurants.
For one-off costing without a spreadsheet, the Recipe Cost Calculator handles the same arithmetic in the browser—add ingredients, set portions, and read off the per-serving cost and suggested selling price.
How to calculate food cost per serving
Food cost per serving (or plate cost) is the batch recipe cost divided by the number of saleable servings. It is the ingredient-cost input for menu pricing.
The food cost per serving formula:
Cost per serving = Total recipe cost ÷ Number of servings
Use the portions the kitchen can produce consistently after trim and cooking loss, then check plated weights against the recipe. For yield calculations and worked examples, see the detailed food cost per serving guide.
One worked example: Chicken Thigh Rice Bowl
Suppose one Chicken Thigh Rice Bowl uses the following quantities from the latest supplier prices. Because the quantities are already converted to the purchase units, each line is simply recipe quantity × unit cost:
| Ingredient | Recipe quantity | Unit cost | Line cost |
|---|---|---|---|
| Chicken thigh | 0.18 kg | $9.50/kg | $1.71 |
| Rice | 0.10 kg | $2.40/kg | $0.24 |
| Mixed vegetables | 0.08 kg | $3.75/kg | $0.30 |
| Sauce | 0.03 L | $8.00/L | $0.24 |
| Oil, garnish, and seasoning | — | — | $0.15 |
| Plate cost | — | — | $2.64 |
For illustration, at a chosen 30% food-cost target the starting price is $2.64 ÷ 0.30 = $8.80. At a rounded $9.00, the actual food cost is $2.64 ÷ $9.00 × 100 = 29.3%. The remaining $6.36 is food gross profit before other sale-linked costs, not net profit.

How to price a menu item with food cost percentage
Pricing from food cost percentage means dividing plate cost by a chosen target ratio to get a starting price. The target should reflect the item’s economics and the price customers may accept; it is not a universal band.
The menu price formula:
Menu price = Plate cost ÷ Target food cost % (as a decimal)
For illustration, if a plate costs $3.55 and the chosen target is 30% (0.30), the starting price is $3.55 ÷ 0.30 = $11.83. At a rounded $12, food cost is 29.6%.
A pricing pass for one menu:
- Cost each plate using current prices and a realistic portion yield.
- Choose an item target from the supported selling price, variable costs, and contribution needed from the sale.
- Calculate a starting price, then compare it with customer expectations and local alternatives. A large gap may call for a portion, ingredient, or positioning review.
- Round and reverse-check the actual food cost percentage at the final price. Price display is a separate decision; see our guide on pricing psychology and currency signs.
For the full pricing workflow—including how to handle items that cannot hit the planned contribution, how to use anchors and decoys, and a worked pricing pass for a full menu—see our guide on how to price a menu item with food cost percentage.
For a single-item check, the Menu Pricing Calculator takes plate cost and target percentage and returns the suggested price—and reverse-calculates the real food cost on any existing price.
Food cost percentage vs gross margin: which should guide menu prices?
Food cost percentage and food gross margin percentage are complementary ratios: food cost is the share of price spent on ingredients; food gross margin is the share left after ingredients. Food gross profit is that amount in dollars. Item contribution subtracts other variable costs attached to the sale as well.
The core formulas side by side:
Food cost % = Plate cost ÷ Menu price × 100
Food gross margin % = (Menu price − Plate cost) ÷ Menu price × 100
Item contribution = Menu price − plate cost − other sale-linked variable costs
A $12 dish at 30% food cost (plate cost $3.60) and a $24 dish at 30% food cost (plate cost $7.20) share a 70% food gross margin, but return different food gross profit per sale: $8.40 and $16.80. Sales volume and other variable costs change the menu-level contribution, so compare all three measures when deciding what to promote.
The practical rule:
- Use food cost percentage to compare ingredient cost with selling price.
- Use food gross profit per sale to compare the dollars left after ingredients.
- Use item contribution when packaging, commissions, payment fees, discounts, or other variable selling costs change the economics by channel.
For the full comparison—including a worked menu-engineering example that ranks items by percentage, profit dollars, and channel costs—see our guide on food cost percentage vs gross margin.
How to set a food-cost target
There is no single food-cost percentage that fits every venue or item. Derive a target from the price the market can support, the costs attached to each sale, and the contribution the item needs to leave for labor, occupancy, and profit.
For an item, start with:
Maximum ingredient cost = Menu price − Other variable cost per sale − Required item contribution
Target food cost % = Maximum ingredient cost ÷ Menu price × 100
For example, at an $18 selling price, with $1.50 in other sale-linked costs and a planned $10 contribution after variable costs, the ingredient allowance is $6.50. That implies a 36.1% food-cost target for this example—not a general recommendation. If the implied ingredient allowance is too low for the recipe, revisit the price, portion, ingredients, or contribution plan.
For a menu-level view, weight items by actual sales rather than averaging their percentages:
Weighted theoretical food cost % = Sum(standard plate cost × units sold) ÷ Net food sales × 100
Actual food cost = Beginning inventory + Purchases − Ending inventory
Actual food cost % = Actual food cost ÷ Net food sales × 100
Use sales and inventory figures from the same period and compare the weighted result with actual food cost. A gap calls for checking invoices, stock counts, waste, portions, and sales mix. The detailed menu pricing guide walks through item-level choices; the food cost percentage vs gross margin guide explains which result to use when comparing dishes.
How often should a restaurant re-cost its menu?
Set a recurring review interval that fits supplier-price volatility and sales volume, then re-cost affected items when prices, recipe specs, portions, or yield change. One workable schedule is a quarterly full-menu review plus change-triggered checks for high-volume dishes and volatile ingredients.
A practical re-costing cadence:
- On supplier or recipe changes: Re-cost every affected dish and update its starting price.
- After a menu launch: Check actual portions and yields against the recipe spec once the kitchen has served the item.
- At the full-menu review: Compare weighted theoretical cost and item contribution with actual sales and inventory results.
Tie re-costing to invoice review so changed prices do not sit unnoticed in the template.

Frequently asked questions
What is a good food cost percentage for a restaurant?
There is no universal target. Work backward from a selling price customers will accept, subtract other variable costs and the contribution the item needs to leave, then compare the resulting ingredient allowance with the recipe cost. Review the menu-level result against actual sales mix and inventory.
How do you calculate food cost for a recipe?
To calculate restaurant food cost for a recipe, list every ingredient including oils and garnishes, record the purchase unit and price from the latest invoice, convert the recipe quantity to the same unit, multiply quantity by unit cost for each ingredient, and sum every line. Apply a yield or waste factor if the recipe loses weight in cooking. The result is the total recipe cost; divide by portions to get the per-serving cost.
What is the difference between food cost percentage and contribution margin?
Food cost percentage is plate cost divided by menu price. Food gross profit is menu price minus plate cost. Item contribution also subtracts other variable costs tied to the sale, such as packaging or commissions. Two dishes can share a food-cost percentage but leave different dollars after ingredients and other sale-linked costs.
How often should menu prices be updated?
Review prices when supplier costs, portions, recipe specs, or selling conditions change, and set a recurring full-menu review that fits the operation. Re-cost recipes before deciding whether the new plate cost calls for a menu price change. Live digital menus make the price update quick once the decision is made.
Does food cost include labor?
No. Food cost covers ingredients only. Prime cost typically means food and beverage cost plus direct labor; packaging may be tracked separately or included in cost of goods sold depending on accounting policy. Food cost percentage is a menu-pricing tool, while prime cost is an overall profitability check.
