How to Calculate Food Cost Percentage (With Real Examples)

You sell a smash burger for $12. You think you're making good money. But do you actually know how much that burger costs to make?

$3.42? $5.10? $7.80?

The answer changes everything — your profit, your pricing, whether your business survives the next 12 months. That number is your food cost percentage, and most restaurant and food truck owners either don't calculate it, or calculate it wrong.

Let's fix that.

The Food Cost Formula

Here's the formula. It's simple:

Food Cost % = (Ingredient Cost ÷ Selling Price) × 100

That's it. The cost of every ingredient in one dish, divided by what you charge for it, times 100.

If your smash burger costs $3.42 in ingredients and you sell it for $12.00:

($3.42 ÷ $12.00) × 100 = 28.5% food cost

That 28.5% means for every dollar a customer pays, roughly 29 cents goes to ingredients. The rest covers labor, rent, overhead, and — hopefully — profit.

Step-by-Step: Calculating Food Cost for a Dish

Let's walk through a real example. Say you run a food truck and your best seller is a loaded chicken burrito.

Step 1: List every single ingredient.

Not just the big stuff. Everything. The tortilla, the chicken, the rice, the beans, the salsa, the sour cream, the foil wrapper. If it goes into (or around) the dish, it counts.

Step 2: Calculate the cost of each ingredient per portion.

This is where most people mess up. You buy chicken breast at $8.99/kg, but you use 180g per burrito. So:

• Chicken breast: ($8.99 ÷ 1000g) × 180g = $1.62
• Flour tortilla (12-pack, $4.49): $4.49 ÷ 12 = $0.37
• Rice (5kg bag, $6.99): about 120g cooked per serving = $0.17
• Black beans (can, $1.29): 1/4 can per serving = $0.32
• Cheese (shredded, 500g, $5.99): 40g per serving = $0.48
• Salsa (jar, $3.49): ~60ml per serving = $0.29
• Sour cream (500ml, $3.99): ~30ml per serving = $0.24
• Foil wrapper: $0.05

Step 3: Add it all up.

$1.62 + $0.37 + $0.17 + $0.32 + $0.48 + $0.29 + $0.24 + $0.05 = $3.54

Step 4: Divide by your selling price.

You sell the burrito for $11.50.

($3.54 ÷ $11.50) × 100 = 30.8% food cost

That's in the acceptable range for a food truck (28-32%), but it's on the higher end. A few cents saved per ingredient adds up fast when you sell 80 burritos a day.

What's a Good Food Cost Percentage?

It depends on your business type. Here are industry benchmarks:

| Business Type | Target Food Cost % | |---|---| | Food Truck | 28–32% | | Fast Casual | 28–35% | | Casual Dining | 28–35% | | Fine Dining | 30–40% | | Ghost Kitchen | 25–32% | | Pizza | 20–28% | | Coffee / Bakery | 20–30% |

These are averages. Your actual target depends on your labor costs, rent, and overhead. A food truck with low rent can tolerate slightly higher food cost. A fine dining restaurant with expensive labor needs tighter control elsewhere.

The golden rule: if your food cost is above 35%, you're almost certainly losing money on that dish — unless everything else in your operation is extremely lean.

The 3 Mistakes Almost Everyone Makes

Mistake 1: Forgetting small ingredients.

Cooking oil, salt, pepper, garnishes, sauces, packaging. They seem insignificant per dish but they add up. A food truck selling 200 dishes/day with $0.15 in untracked "invisible" ingredients is losing $30/day — over $900/month.

Mistake 2: Using old prices.

You calculated your food cost 6 months ago. Since then, chicken went up 12%, cheese went up 8%, and cooking oil went up 20%. Your food cost percentage has silently crept up, and your margins have silently crept down. Prices change monthly. Your calculations should too.

Mistake 3: Calculating by category instead of by dish.

"My overall food cost is 31%." Cool — but which dishes are at 22% and which are at 45%? Averaging hides the problem. You need to know the food cost of every single dish on your menu. That $18 pasta with the imported truffle oil at 48% food cost is dragging your whole menu down.

Food Cost vs. COGS: What's the Difference?

People often confuse these two. They're related but different.

Food cost percentage is about individual dishes — what percentage of a dish's selling price goes to ingredients.

COGS (Cost of Goods Sold) is about your entire business over a period — total food purchases divided by total food revenue. COGS includes waste, spoilage, theft, and over-portioning. It's always higher than your theoretical food cost.

If your calculated food cost per dish averages 30% but your actual COGS is 38%, that 8% gap is waste, spoilage, and portioning errors. That gap is money on the floor.

How to Lower Your Food Cost

Once you know your numbers, here are the highest-impact moves:

1. Find your worst dishes first. Calculate food cost for every dish on your menu. Sort by food cost %. The dishes above 35% are bleeding money. Fix those first — reprice them, reduce portion size, or find cheaper ingredients that don't change the taste.

2. Track ingredient prices monthly. When tomatoes go up 20%, every dish with tomatoes gets more expensive. You should know this immediately, not discover it when your bank account looks thin.

3. Swap invisible ingredients. Many ingredients can be replaced with cheaper alternatives that customers won't notice. Generic brand spices instead of name brand. A different oil. A similar cheese. These "invisible swaps" can save 5-10% on ingredient costs without any change in taste.

4. Negotiate with suppliers. Most food truck owners and small restaurants accept the first price. Ask for volume discounts. Compare at least 2-3 suppliers. Even a 5% discount on your top 3 ingredients can save hundreds per month.

5. Control portions. If your recipe calls for 150g of chicken and your cooks are eyeballing 180-200g, your food cost is 15-30% higher than you think. Use scales. Use portion cups. Standardize.

FAQ

What is food cost percentage?

Food cost percentage is the ratio of a dish's ingredient cost to its selling price, expressed as a percentage. If a dish costs $4 to make and sells for $12, the food cost is 33.3%.

What is the formula for food cost?

Food Cost % = (Total Ingredient Cost ÷ Selling Price) × 100. Calculate the cost of every ingredient in one portion of a dish, divide by the menu price, and multiply by 100.

What is a good food cost percentage?

For most restaurants, 28-35% is considered healthy. Food trucks should aim for 28-32%. Fine dining runs higher at 30-40%. If you're consistently above 35%, you're likely losing money on that dish.

How often should I calculate food cost?

At minimum, recalculate whenever ingredient prices change significantly — which in practice means monthly. The best operators track it weekly. Ingredient prices fluctuate constantly, and a 10% increase in a key ingredient can silently destroy your margins.

How do I lower my food cost without changing the menu?

Focus on three things: find cheaper ingredient substitutions that don't affect taste, negotiate better supplier prices, and tighten portion control. Most restaurants can save 3-8% on food cost through these changes alone, without removing or changing any dishes.

What's the difference between food cost and COGS?

Food cost percentage is a theoretical number based on recipe calculations. COGS (Cost of Goods Sold) is the actual amount you spent on food in a period divided by food revenue. COGS is always higher because it includes waste, spoilage, and over-portioning. The gap between the two tells you how much money you're losing to operational inefficiency.

Can FoodCostly calculate this for me automatically?

Yes. FoodCostly tracks all your dishes, calculates food cost percentage automatically, alerts you when ingredient prices change, and uses AI to suggest cheaper ingredient alternatives. It's free for up to 10 dishes.
