Many restaurant owners think high food costs mean they need to overhaul their entire menu. That's rarely true. The real issue is usually just 3-5 dishes quietly draining your profits while the rest perform fine.
First check where the problem is
Before you start adjusting prices, you need to know which dishes are causing the problem. Not all dishes have the same impact on your profit.
? Example:
Restaurant De Keuken has 15 dishes on the menu:
- 5 dishes with 28% food cost (great)
- 7 dishes with 32% food cost (acceptable)
- 3 dishes with 42% food cost (problem!)
Focus on those 3 dishes, not all 15.
Calculate your new minimum selling price
For each problematic dish, calculate what the minimum selling price needs to be to achieve a healthy food cost. The formula is simple:
Minimum selling price excl. VAT = Ingredient costs ÷ (Desired food cost % ÷ 100)
? Example calculation:
Steak with ingredient costs of €12.50:
- Desired food cost: 30%
- Minimum price excl. VAT: €12.50 ÷ 0.30 = €41.67
- Minimum price incl. 9% VAT: €41.67 × 1.09 = €45.42
If you're currently charging €38.50, you're losing money on every portion.
⚠️ Note:
Always calculate first excl. VAT and then add VAT afterwards. Otherwise you'll make an error of 2-3 percentage points in your food cost.
Choose your strategy: raise prices or lower costs
You have three options to lower your food cost. Often a combination works better than going all-in on one approach:
- Raise selling price: Most direct solution, but can scare off customers
- Lower ingredient costs: Different supplier, different products, smaller portions
- Remove dish from menu: Drastic, but sometimes necessary for chronic money-losers
? Example strategy choice:
Seafood pasta, current situation:
- Selling price: €24.50 (€22.48 excl. VAT)
- Ingredient costs: €9.80
- Food cost: 43.6% (way too high!)
Option 1: Raise price to €28.50 → food cost becomes 32%
Option 2: Lower costs to €7.50 → food cost becomes 33%
Option 3: Combination: price €26.50 + costs €8.00 → food cost becomes 33%
Raise prices smartly and gradually
Price increases don't necessarily scare off customers if you do it right. Most guests accept reasonable increases, especially if quality stays consistent.
- Start with your least popular dishes: Less impact, less noticeable
- Increase in steps of €1.50-€2.50: Big jumps are too obvious
- Don't change everything at once: Spread it over 2-3 months
- Don't announce price increases: Just quietly implement them
Lower ingredient costs without losing quality
Sometimes you can lower costs without guests noticing. After managing kitchen operations for nearly a decade, I've found this requires more creativity than raising prices, but it's often more effective.
- Different supplier: Compare prices, especially for expensive ingredients
- Use seasonal products: Winter tomatoes cost 3x more
- Adjust portion sizes: 200g meat instead of 250g saves €2-3 per portion
- Look critically at garnish: Those expensive microgreens cost €0.80 per plate
? Example cost reduction:
Salmon dish, original costs €11.20:
- Salmon 180g → 160g: savings €1.20
- Expensive garnish → simpler: savings €0.60
- Different vegetable supplier: savings €0.40
New costs: €9.00 (€2.20 savings per portion)
Monitor results and adjust
After making changes, you need to watch whether the desired effect occurs. Food costs can fluctuate due to seasons and supplier prices.
- Check your food cost per dish monthly
- Watch your total revenue: Are sales declining due to higher prices?
- Keep an eye on supplier prices: They can go up again
- Adjust again if needed: This isn't a one-time action
A food cost calculator like KitchenNmbrs helps track these numbers automatically, so you quickly see when adjustments are needed.
How do you adjust your menu? (step by step)
Analyze your current food cost per dish
Calculate for each dish: (ingredient costs ÷ selling price excl. VAT) × 100. Focus on dishes above 35% food cost.
Calculate new minimum prices
For problematic dishes: ingredient costs ÷ (desired food cost % ÷ 100). Then add 9% VAT for the menu price.
Choose your approach per dish
Decide whether you raise the price, lower costs, or do a combination. Start with the least popular dishes.
Implement changes gradually
Don't change everything at once. Spread price increases over 2-3 months and raise in steps of €1.50-€2.50.
Monitor and adjust
Check your food cost and total revenue monthly. Supplier prices change, so this isn't a one-time action.
✨ Pro tip
Track your top 8 dishes for 2 weeks straight. If those have healthy food costs, you've already solved 75% of your problem - don't waste time tweaking dishes you barely sell.
