What is food cost?

Food cost is the percentage of a dish's selling price that goes to its raw ingredients. The formula is simple: Food Cost % = (Total Ingredient Cost ÷ Selling Price) × 100. A pasta dish that sells for $18 with $5.40 of ingredients has a 30% food cost. The remaining 70% covers labor, rent, utilities and profit.

But here is the catch: most recipes use the wrong number for "ingredient cost." They use the price you paid the supplier (As-Purchased cost, or AP cost), not the price of what actually ends up on the plate. That single oversight is why so many menus look profitable on paper and lose money in real life.

The hidden mistake: ignoring trim loss

The most common error in restaurant kitchens has nothing to do with math. Chefs confuse two different recipes:

1. The kitchen recipe — what the chef actually cooks. Specifies trimmed, ready-to-cook quantities ("180 g beef tenderloin, seared").
2. The costing recipe — what you use to calculate food cost. Must include the raw, untrimmed quantity you actually paid for, plus the yield loss from trimming, deboning, peeling, or cooking shrinkage.

If you cost a dish using the kitchen recipe (180 g of trimmed tenderloin), you are pretending the trim, fat and silver skin were free. They were not. You bought them. They are in your invoice.

Real example. A whole beef tenderloin costs $42/kg as-purchased. After trimming silver skin, fat and head, you keep around 70% of the original weight. The real cost of the tenderloin you serve is:

EP Cost = AP Cost ÷ Yield % = $42 ÷ 0.70 = $60/kg

So a 180 g portion costs $10.80 in raw material — not the $7.56 you would calculate using the kitchen recipe. On a dish that sells for $32, that is the difference between a 23.6% food cost and a 33.7% food cost. Multiply that gap by 3,000 covers a month and you have found where the missing margin went.

How to calculate true EP cost

Step 1 — Calculate yield percentage. Buy the product. Trim it the way you would for service. Weigh what is left.

Yield % = (Edible Portion Weight ÷ As-Purchased Weight) × 100

If you buy 1,000 g of whole chicken and end up with 720 g of usable meat after deboning, your yield is 72%.

Step 2 — Calculate EP cost per unit.

EP Cost = AP Cost ÷ Yield %

Use the EP cost as the input in your costing recipe — never the AP cost. The calculator above does this for you when you enter the yield % per ingredient.

Typical yield percentages — quick reference

These are realistic ranges based on standard culinary references. Your numbers will vary by product quality and butcher technique — always run your own yield test for high-volume ingredients.

Ingredient	Typical Yield %	Trim Loss %
Beef tenderloin (whole, untrimmed)	65–75%	25–35%
Whole chicken (deboned, skinless)	70–75%	25–30%
Salmon (whole, filleted)	55–65%	35–45%
Halibut fillet (skin-on)	80–90%	10–20%
Tomatoes (concassé)	75–80%	20–25%
Bell peppers (cleaned)	75–82%	18–25%
Onions (peeled, diced)	85–90%	10–15%
Iceberg lettuce	70–75%	25–30%
Carrots (peeled)	80–85%	15–20%
Potatoes (peeled)	78–85%	15–22%
Pineapple (peeled, cored)	50–55%	45–50%
Hard cheese (rind removed)	90–95%	5–10%

For a single beef tenderloin, the difference between 65% yield and 75% yield is significant. On a $42/kg AP cost, that is the gap between $64.60/kg and $56/kg of EP cost — a 15% swing in your raw material price. This is why supplier consistency matters more than most chefs realize.

Why supplier consistency matters

Yield % is not a fixed number. It depends on the cut and quality grade of the product, how aggressive the butcher is at the supplier, seasonality, and storage conditions before delivery.

If you change suppliers every other week chasing the cheapest price, you are also changing your yield % every other week. Your costing recipes go out of date the moment a new pallet arrives. You think you are saving 5% on the invoice and losing 8% on the plate.

The opposite strategy works better. Pick two or three suppliers per category, build a relationship, and lock in consistent quality. Then run a yield test once per quarter, not once per delivery. Your costing recipes stay accurate, your prep times stay predictable, and your line cooks stop arguing with the receiving team.

When to recalculate yield:

• You change supplier
• The supplier changes their cut or grade
• You spot a noticeable difference in trim or quality at receiving
• Seasonal shift on key produce
• Anytime margin slips and you cannot explain why

Target food cost percentages by restaurant type

There is no single "right" food cost. The healthy range depends on your concept, location and labor model. These are realistic benchmarks:

• Fine dining: 25–32%. Higher menu prices and lower volume justify deeper investment in premium ingredients.
• Casual dining (full service): 28–35%. The most common range for mid-market restaurants.
• Pizzeria / pasta: 26–32%. Lower-cost base ingredients, simpler prep, leaner food cost expected.
• Steakhouse: 35–42%. Protein-heavy menus run higher food cost, offset by higher ticket averages.
• Quick service / fast casual: 28–35%. Volume-driven, tight margins per dish.
• Bar / gastropub: 28–34% on food, 18–22% on beverages.

If your overall food cost is more than 5 percentage points above your target, the problem is rarely the menu prices. It is usually one of: portion creep, waste, theft, supplier price changes you have not passed through, or trim loss you never accounted for in the first place.

5 common food cost mistakes

1. Costing with the kitchen recipe instead of the costing recipe. The single most expensive mistake in any kitchen.
2. Ignoring secondary ingredients. Salt, oil, butter, herbs, garnish and the bread basket all have costs. They look small per dish, but on 3,000 covers a month they add 2–4 percentage points to your real food cost. Cost them in.
3. Forgetting cooking shrinkage. A 200 g raw burger is not 200 g cooked. Beef loses 20–25% weight on the grill. If your recipe says "200 g cooked patty," start with 250–270 g raw. Cost the raw weight, not the cooked.
4. Using outdated supplier prices. Recipes built six months ago are no longer accurate. Olive oil has gone up significantly since 2023. Eggs went through three price waves. If you have not refreshed costs in the last 90 days, your margins are already wrong.
5. Pricing the menu by gut feel. "It feels right at $24" is not a strategy. Set a target food cost % per dish, calculate the EP cost, divide by the target percentage — that is your minimum price. Then adjust for psychological price points.

How to use this calculator

1. Enter ingredients with AP cost per kg or liter — the price your supplier invoices you.
2. Enter the recipe quantity — what actually goes on the plate (the kitchen recipe quantity).
3. Set the waste % per ingredient to convert AP cost to EP cost automatically.
4. Set your target food cost % using the benchmarks above.
5. Read the suggested menu price — minimum price to hit your target margin. Round up to a psychological price point.

Save the dish, export to PDF, share it with your sous chef. Recalculate whenever your AP costs or yield % change.
