What Is Plate Cost? (And How to Calculate It for Every Dish)
Plate cost is the total ingredient cost for one serving of a dish. It is the foundation of menu pricing and profitability decisions. Here is how to calculate it correctly including yield adjustments.
What Is Plate Cost? (And How to Calculate It for Every Dish)
Plate cost is the total ingredient cost to produce a single serving of a dish. It is the most granular food cost metric you have -- and the one that actually determines whether a dish makes money. Most operators know their overall food cost percentage; fewer know the plate cost of every item on their menu. That gap is expensive.
Plate Cost vs. Food Cost Percentage
These two metrics are related but serve different purposes:
- Food cost % = Total food cost divided by total revenue x 100 (useful for tracking trends)
- Plate cost = Sum of every ingredient cost in one serving (useful for making decisions)
Food cost percentage tells you how your whole operation is performing. Plate cost tells you exactly how much a specific dish costs to make -- which is what you need to price confidently and spot money-losers.
How to Build a Plate Cost Card
A cost card breaks down every ingredient in a dish with its unit cost and quantity used.
Step 1: List Every Ingredient
Include everything: garnishes, sauces, sides. A $0.15 lemon wedge or $0.20 in butter feels negligible -- until you multiply it across 300 covers per day.
Step 2: Calculate Unit Cost
You need a cost per usable unit for each ingredient. If you buy chicken breast for $4.50 per lb, your unit cost starts at $4.50 per lb -- before yield adjustments.
Step 3: Apply Yield Adjustments -- Most Operators Get This Wrong
Raw ingredients do not equal usable ingredients.
Adjusted cost = Purchase price divided by Yield %
If chicken breast yields 80% after trimming and cooking: $4.50 / 0.80 = $5.63 per lb of usable meat
Common yield percentages:
| Ingredient | Typical Yield |
|---|---|
| Chicken breast (boneless) | 80-90% |
| Beef (bone-in cuts) | 60-75% |
| Fish fillets | 80-90% |
| Leafy greens | 70-80% |
| Root vegetables | 80-85% |
Step 4: Multiply and Sum
For each ingredient: Quantity used x Adjusted unit cost = Ingredient cost
Add them all up. That total is your plate cost.
Worked Example: Grilled Salmon Plate
| Ingredient | Purchase Cost | Yield % | Adjusted Cost | Qty Used | Item Cost |
|---|---|---|---|---|---|
| Salmon fillet | $9.00/lb | 85% | $10.59/lb | 7 oz | $4.63 |
| Mixed vegetables | $2.50/lb | 80% | $3.13/lb | 5 oz | $0.98 |
| Butter | $3.20/lb | 100% | $3.20/lb | 1 oz | $0.20 |
| Lemon | $0.40 each | 90% | $0.44 each | 0.5 each | $0.22 |
| Olive oil, salt, herbs | -- | -- | -- | -- | $0.18 |
| Total plate cost | $6.21 |
If this dish sells for $24, food cost percentage is 25.9% -- right in range for a seafood dish.
How Often Should You Recost?
Ingredient prices change. Plate costs expire. Build a review schedule:
- Monthly: Update your top 10 most-used ingredients
- Quarterly: Full menu recosting
- Immediately: Any time a key supplier raises prices more than 5%
A 10% spike in salmon prices might move plate cost by only $0.60 -- but at 80 portions per week, that is $2,500 per year in eroded margin if you do not catch it.
Why Plate Cost Is the Foundation of Everything
You cannot price well without it. You cannot spot your worst performers without it. And you cannot have a meaningful conversation with your kitchen team about waste without real numbers.
Once you know plate cost for every dish, you can price with confidence, identify margin-draining items, and make ingredient decisions based on data -- not instinct.
Frequently Asked Questions
What is a good plate cost for a restaurant dish?
For most restaurant concepts, you want plate cost to be 28-35% of menu price. A dish priced at $20 should ideally cost $5.60-$7.00 to make. The right target depends on your concept type and full P&L.
How do I handle batch-cooked items like stocks and sauces?
Calculate the total cost of the full batch (all ingredients), then divide by the number of portions the batch yields. Use the resulting per-portion cost in your plate cost calculation.
What is the difference between plate cost and recipe cost?
They are the same thing. "Plate cost," "recipe cost," and "portion cost" are all interchangeable terms for the total ingredient cost for one serving.
Should I include packaging in plate cost?
For dine-in, typically no. For delivery or takeout operations, yes -- packaging is a direct cost of producing that serving, and excluding it will understate your true cost.
