Running a restaurant today feels like trying to fill a bucket with a massive hole in the bottom. You're pouring in more effort, longer hours, and higher revenue, but your profits keep draining away faster than you can replenish them. The culprit isn't usually fewer customers—it's the silent cost creep that's bleeding your margins dry.
Where does your profit disappear?
The issue isn't fewer guests walking through your door or slashing menu prices. It's those sneaky costs that climb higher each month while you operate with outdated numbers and old assumptions.
💡 Example:
Restaurant De Smulhoek maintains €50,000 monthly revenue but watches profits vanish:
- 2022: €8,000 monthly profit
- 2023: €6,500 monthly profit
- 2024: €4,200 monthly profit
Same revenue, 47% profit loss
The stealth cost bombers
These expenses balloon behind the scenes while your menu prices stay frozen in time:
Supplier price explosions
Your suppliers bump prices 10-20% annually. You don't touch your menu. Every dish now bleeds more money, but you're still charging yesterday's prices.
💡 Example:
Your €28.50 steak special:
- 2022: €6.50 meat cost per portion = 25% food cost
- 2024: €8.20 meat cost per portion = 32% food cost
Seven points higher food cost = €1.70 less profit per steak
Energy bills through the roof
Gas and electricity costs have doubled or tripled. Your ovens, freezers, and lighting now devour your budget.
Staff costs spiral upward
- Annual minimum wage hikes
- Rising pension contributions
- Expensive sick leave coverage
- Staff shortage = premium wages to attract talent
Portion inflation strikes
Your kitchen staff adds a little extra each service. That 200-gram portion becomes 220 grams. One splash of wine becomes two. Small changes that create massive yearly losses. I've seen this mistake cost restaurants EUR 200-400 monthly without anyone noticing until the books close.
⚠️ Watch out:
Just 20 extra grams of meat per portion costs you €15,000 yearly at 100 weekly portions (based on €15/kg meat costs).
The death spiral begins
Lower profits push you toward desperate cost-cutting in all the wrong places:
- Cheaper ingredients: Quality plummets, customers flee
- Skeleton crew staffing: Service suffers, stress skyrockets
- Deferred maintenance: Equipment fails more often, repair bills multiply
- Zero investment: Your restaurant stagnates while competitors modernize
So you work harder but earn less. And the cycle continues.
Breaking free from the profit trap
Working harder won't save you—you need smarter management. You must track where every euro goes.
1. Calculate real food costs now
Crunch the numbers on your 10 top-selling dishes using current supplier prices. Not what you assume they cost, but what you're actually paying today.
2. Restructure prices systematically
If food costs jumped from 28% to 35%, your selling prices must follow. Formula: New price = Ingredient costs / (Target food cost% / 100)
💡 Example:
Pasta carbonara with €8.20 ingredient cost:
- At 30% food cost: €8.20 / 0.30 = €27.33 excl. VAT
- With 9% VAT: €27.33 × 1.09 = €29.79
New menu price: €29.80
3. Monitor portion control religiously
Weigh key ingredients for one full week. Is your kitchen hitting target portions? If not, establish clear standards and stick to them.
4. Weekly cost surveillance
Review major expenses weekly, not monthly when it's too late. Spot troubling trends before they demolish your monthly profit.
Food cost tracking tools help you catch rising costs immediately and react before they destroy your margins.
How do you find where your profit goes? (step by step)
Calculate your actual food cost right now
Take your 5 best-selling dishes. Add up all ingredient costs at current supplier prices. Divide by selling price excl. VAT and multiply by 100.
Compare with last year
Find your old purchase invoices from 12 months ago. Calculate the same food cost back then. The difference shows you where the profit went.
Check your other fixed costs
Compare energy, staff and rent costs now with last year. Add up the increases and divide by your monthly revenue for the percentage impact.
Calculate new prices
For dishes with food cost above 33%: calculate new selling price with formula (ingredient costs / desired food cost%). Add VAT for menu price.
Update menu in phases
Don't raise everything at once. Start with 3-4 dishes that perform worst. Monitor guest reaction and adjust more after that.
✨ Pro tip
Track your top 3 revenue-generating dishes weekly for the next 8 weeks. These three items typically represent 60-70% of your food cost exposure, so controlling them controls your profit.

Frequently asked questions
Can't I just reduce purchasing to cut costs?
Buying less won't help when fixed expenses (rent, labor, utilities) keep climbing. You must align selling prices with actual costs, or every sale becomes a loss.
Won't customers abandon us if we raise prices?
Some might, but 80 profitable customers beat 100 loss-making ones. Plus, price increases are industry-wide now—customers expect them.
How frequently should I review food costs?
Monthly minimum for your bestsellers. During high inflation or supplier changes, check every two weeks. Stay ahead of cost spikes instead of reacting after damage is done.
What if competitors keep lower prices?
Your competitor is likely losing money too, or cutting quality corners. Focus on your own sustainability—you can't sell below cost and survive long-term.
What's the acceptable food cost ceiling?
Most restaurants target 28-35%. Above 35% makes it nearly impossible to cover other expenses (labor, rent, utilities) while generating profit.
Should I increase all menu prices simultaneously?
Start with your worst-performing dishes (highest food cost percentage). Test customer response, then adjust other items gradually. This approach minimizes shock.
How do I calculate the exact price increase needed?
Use this formula: (Current ingredient cost / Target food cost percentage) × VAT multiplier. For example, €10 ingredients at 30% target = €10 ÷ 0.30 = €33.33 base price.
