Your head chef just plated 240g of beef tenderloin instead of the 200g your recipe calls for. That single over-portion just cost you €1.80, and it happens dozens of times daily across your most expensive ingredients. Calculate exactly how much you'll save by precisely weighing your top 10 costliest items.
Why weighing saves so much money
Give your chef 250 grams of steak instead of 200 grams, and you're bleeding money with every plate. Expensive ingredients turn these small overages into massive annual losses - a mistake that costs the average restaurant EUR 200-400 per month.
💡 Example:
You use beef tenderloin at €45/kg. Recipe calls for 200g, chef gives 240g:
- Extra per portion: 40g × €0.045 = €1.80
- At 30 portions per week: €54
- Per year: €2,808 loss
Just on this one ingredient!
Identify your top 10 most expensive ingredients
Start with ingredients that pack the biggest financial punch. These create the most dramatic impact on your bottom line:
- Meat and fish: steak, salmon, lobster, lamb
- Luxury products: truffle, caviar, foie gras
- Nuts and seeds: pine nuts, pistachios
- Specialty cheeses: parmesan, goat cheese
- Oils: truffle oil, extra virgin olive oil
⚠️ Note:
Focus on ingredients above €15 per kilo. Weighing cheap products won't move the needle much.
Calculate the difference per portion
For each ingredient, figure out the gap between what you're actually serving versus what your recipe specifies:
Formula: (Actual weight - Recipe weight) × Price per gram
💡 Example calculation top 5:
- Beef tenderloin: 40g extra × €0.045 = €1.80
- Salmon: 25g extra × €0.028 = €0.70
- Parmesan: 10g extra × €0.032 = €0.32
- Pine nuts: 5g extra × €0.065 = €0.33
- Truffle oil: 3ml extra × €0.180 = €0.54
Total loss per plate: €3.69
Calculate on an annual basis
Multiply your per-portion loss by total yearly covers:
Formula: Loss per portion × Portions per day × Working days per week × 52 weeks
💡 Example restaurant with 80 covers/day, 6 days/week:
- Loss per portion: €3.69
- Covers per year: 80 × 6 × 52 = 24,960
- Total loss: €3.69 × 24,960 = €92,102
Nearly €100,000 per year from not weighing!
Measure for 2 weeks
Weigh every portion of your top 10 ingredients for 2 solid weeks. Track the variance from your recipes, then calculate average overage per ingredient.
⚠️ Note:
Test across different days and shifts. Busy Saturday nights often see much heavier portions than quiet Tuesday lunches.
Investment in scales
Quality digital scales run €50-150. If you're saving €50,000+ annually, you'll recover this investment in hours, not days.
- Precision: minimum 1 gram accuracy
- Capacity: handles up to 5 kg portions
- Speed: instant readings for busy service
- Hygiene: quick cleanup between uses
How do you calculate annual savings? (step by step)
Make a list of your top 10 most expensive ingredients
Write down your 10 most expensive ingredients with their purchase price per kilo. Focus on products above €15/kg for maximum impact.
Measure actual usage for 2 weeks
Weigh every portion of these ingredients for 2 weeks. Note the difference from your recipe amount per ingredient per day.
Calculate average loss per portion
Calculate per ingredient: (average extra weight × price per gram). Add up all ingredients for total loss per plate.
Multiply by number of covers per year
Formula: loss per portion × covers per day × working days per week × 52. This gives you total annual savings from consistent weighing.
✨ Pro tip
Track your top 10 ingredients across different shifts and kitchen staff for the full 2-week period. Evening crews often portion 15-20% heavier than lunch shifts, which can skew your annual savings calculation by thousands of euros.

Frequently asked questions
Which ingredients must I absolutely weigh?
Start with meat, fish and luxury products above €20/kg. These create the biggest financial impact. You can add cheaper vegetables later once you've mastered the expensive stuff.
How much time does weighing add during service?
With a quality digital scale, you're looking at 5-10 seconds extra per plate. That's nothing compared to saving thousands of euros annually.
What if my chef thinks weighing everything is excessive?
Show them the numbers. If sloppy portioning costs €50,000+ yearly, those extra 10 seconds per plate become a no-brainer investment in profitability.
Should I weigh garnishes and small-quantity ingredients too?
Focus on your top 10 costliest ingredients first. Once that's running smoothly and you're seeing solid results, then expand to other products gradually.
