Meat trimming loss is like an invisible tax on every steak you serve. Most restaurant owners price their dishes based on what they pay per kilo, but they're missing a crucial piece of the puzzle. After you trim fat, remove sinew, and portion properly, you're left with significantly less usable meat than what you purchased.
What is meat trimming loss?
Trimming loss represents the gap between your raw purchase and what actually hits the plate. Several factors contribute to this loss:
- Removing fat and connective tissue during prep
- Odd-shaped pieces that don't portion cleanly
- Moisture loss during refrigeration
- Natural shrinkage while cooking
Take a 3-kilogram beef tenderloin. After proper trimming, you'll have roughly 2.1 kilograms of steaks ready for service. That's a 30% loss right there.
⚠️ Heads up:
Most operators get the math backwards here. They multiply purchase price by yield percentage, but you need to divide by yield since you're working with less product than you bought.
Calculate your real meat cost
Here's the formula that'll give you the true cost per kilogram:
True cost per kg = Purchase price per kg ÷ (Yield % ÷ 100)
Yield percentage equals 100% minus your trimming loss percentage.
💡 Example:
Beef tenderloin costs €45.00 per kg. After trimming, you retain 70% of the original weight.
- Purchase price: €45.00/kg
- Usable yield: 70%
- Real cost: €45.00 ÷ 0.70 = €64.29/kg
You're paying €19.29 more per kilogram than your invoice shows!
Expected trimming loss by cut
From tracking this across dozens of restaurants, here are realistic loss percentages by meat type:
- Beef tenderloin: 25-35% trimming loss
- Ribeye steaks: 15-25% trimming loss
- Strip loin (whole): 30-40% trimming loss
- Pork tenderloin: 20-30% trimming loss
- Leg of lamb: 35-45% trimming loss
- Whole chicken to breast meat: 40-50% trimming loss
Price your steak dish correctly
Once you know the actual meat cost, building your dish price becomes straightforward:
💡 Example: 250-gram ribeye
Ribeye at €28.00/kg with 20% trimming loss:
- True meat cost: €28.00 ÷ 0.80 = €35.00/kg
- Protein cost per serving: 0.25 kg × €35.00 = €8.75
- Sides and sauce: €2.25
- Seasonings and cooking fat: €0.50
Total plate cost: €11.50
If you're selling this at €32.00 including tax (€29.36 before tax), your food cost runs 39.2%. That's pushing it for most steak operations, where 35% is typically the ceiling.
Strategies to minimize trimming loss
Every percentage point you save on trimming directly improves your margins:
- Source smarter: Find suppliers with cleaner, better-trimmed cuts
- Storage matters: Proper wrapping prevents moisture loss
- Tool maintenance: Sharp knives create less waste
- Repurpose scraps: Turn trim into tartare, ground meat, or stock
💡 Financial impact:
You serve 50 steaks weekly and cut trimming loss from 30% to 25%:
- Before: €45.00 ÷ 0.70 = €64.29/kg
- After: €45.00 ÷ 0.75 = €60.00/kg
- Weekly savings: €4.29/kg × 0.25 kg × 50 portions = €53.63
Annual impact: €2,789 in reduced costs!
Digital tracking systems
Spreadsheets and paper logs work, but they're time-consuming and easy to abandon. Digital solutions streamline the process significantly.
Food cost management tools like KitchenNmbrs let you input trimming percentages by ingredient. The system automatically adjusts your true costs and calculates accurate food cost percentages, so you can spot unprofitable dishes before they damage your bottom line.
How do you calculate trimming loss in your cost price? (step by step)
Measure your trimming loss
Weigh the meat before and after trimming. Calculate the percentage: (purchase weight - usable weight) ÷ purchase weight × 100. Do this a few times to get an average.
Calculate your actual meat price
Divide your purchase price by the yield percentage. If you have 25% trimming loss, your yield is 75%. Purchase price ÷ 0.75 = actual price per kg.
Calculate your dish cost price
Multiply the actual meat price by the weight per portion. Add all other ingredients (garnish, sauce, butter). This is your total cost price per dish.
Check your food cost percentage
Divide your cost price by your selling price excl. VAT and multiply by 100. For steak dishes you aim for maximum 35% food cost.
✨ Pro tip
Track trimming loss on your top 3 protein purchases for 30 days to establish baseline percentages. A 3% improvement in yield efficiency can boost annual profits by €1,500-€3,000 depending on volume.

Frequently asked questions
Should I include trimming loss in my cost price?
Absolutely. Trimming loss can increase your actual cost by 20-50% over the invoice price. Skip this calculation and you'll lose money on every plate without knowing why.
How much trimming loss is normal for beef?
Beef tenderloin typically runs 25-35% loss, while ribeye steaks are closer to 15-25%. Quality varies by supplier, so measure your actual yields rather than guessing.
Can I estimate trimming loss instead of weighing?
Don't rely on estimates. Trimming loss fluctuates with supplier quality, seasonal changes, and even individual deliveries. Weigh several batches to establish reliable averages.
What should I do with meat scraps after trimming?
Turn them into revenue instead of waste. Trim works perfectly for tartare, carpaccio, burger blends, or rich stocks. Every scrap you monetize reduces your effective trimming loss.
How often should I update my trimming loss percentage?
Review monthly or whenever you change suppliers. Seasonal quality shifts and different sourcing can alter your yields by several percentage points.
Does cooking method affect how I should calculate trimming loss?
Raw trimming loss stays constant regardless of cooking method. But factor in additional shrinkage if you're pre-cooking or holding proteins, as this creates secondary weight loss beyond initial trimming.
