73% of restaurants see their margins drop by more than 5% annually due to rising costs and static menu prices. Your fixed costs climb every year, but your menu prices don't. The result? Your margins disappear without you realizing it.
What happens to your margins?
Picture this: at the start of 2023 you had a solid 15% margin on total revenue. But while you don't touch your menu prices, your costs keep climbing:
- Rent: +3% (indexation)
- Energy: +25% (market prices)
- Staff: +10% (collective labor agreement increases)
- Ingredients: +8% (inflation)
- Insurance: +5%
💡 Example restaurant:
Annual revenue: €400,000 | Original margin: 15% = €60,000 profit
- Rent rises from €3,000 to €3,090 (+€1,080/year)
- Energy rises from €800 to €1,000 (+€2,400/year)
- Staff rises from €12,000 to €13,200 (+€14,400/year)
- Ingredients rise from €140,000 to €151,200 (+€11,200/year)
Total cost increase: €29,080
New profit: €60,000 - €29,080 = €30,920
Your margin crashes from 15% to 7.7%. More than half your profit has vanished, while your revenue stayed identical.
The hidden impact on your food cost
Here's the killer: your food cost percentage rises, even though you're buying exactly the same ingredients. Why? Because your selling prices stay frozen, but your purchase prices keep climbing.
💡 Example dish:
Steak on your menu: €28.50 (stays the same)
- Beginning 2023: ingredients €8.00 → food cost 30.8%
- End 2023: ingredients €8.64 → food cost 33.2%
Your food cost jumps from 31% to 33% without you noticing.
At 100 steaks per month you're losing an extra €64. Annually? That's €768 on just one dish. Based on real restaurant P&L data, this pattern repeats across your entire menu.
Why restaurant owners don't see this
Most hospitality entrepreneurs spot this problem way too late because:
- Costs creep up gradually: €50 here, €100 there - not obvious per month
- Revenue stays steady: a packed restaurant creates false confidence
- No systematic tracking: food cost isn't monitored monthly
- Revenue obsession: "we're crushing it" while margins evaporate
⚠️ Watch out:
Many entrepreneurs only discover at year-end that there's less profit. By then it's too late to course-correct.
The domino effect on your cashflow
Shrinking margins create cashflow nightmares:
- Less buffer: unexpected expenses become impossible to cover
- Supplier delays: because less cash is flowing in
- Deferred investments: no funds for maintenance or equipment upgrades
- Constant stress: always worrying about money
💡 Cashflow calculation example:
With €29,000 less profit per year:
- Per month: €2,417 less cashflow
- Per week: €558 less to pay bills
- Enough for 2-3 days of staff wages
How to prevent this
The fix is straightforward: adjust your prices systematically. Not one massive jump once yearly, but regular small bumps.
- Monthly checks: have your purchase prices climbed?
- Immediate adjustments: don't wait until year-end
- Honest communication: explain why prices are rising
- Monitor your food cost: keep it under 35%
A system like KitchenNmbrs alerts you automatically if your food cost gets too high, so you can adjust immediately instead of getting blindsided at year-end.
How do you calculate the impact? (step by step)
Calculate your current total costs
Add up all fixed costs: rent, energy, staff, insurance, depreciation. Also your food cost (ingredients as a percentage of revenue). This is your starting point.
Calculate the cost increases per category
Check how much each cost item has risen. Rent often 2-4% per year, energy can be 20-30%, staff 8-12% due to collective labor agreements. Add up all increases in euros per year.
Calculate your new margin
Subtract the total cost increase from your original profit. Divide the result by your revenue to get your new profit margin. This shows how much your margin has shrunk.
✨ Pro tip
Track your profit per customer, not just total revenue. If you're serving 100 customers daily but making €2 less profit per customer after 6 months, you've lost €36,500 in annual profit without changing anything else.
Calculate this yourself?

Frequently asked questions
How much do costs typically rise per year in hospitality?
Fixed costs usually climb 5-8% annually. Energy can spike much higher (20-30%), while rent often rises 2-4% through indexation. Ingredients follow inflation, typically 3-8% per year.
By how much should I increase my prices?
This depends on your specific cost increases. Rule of thumb: if your costs rise 5%, bump your prices by 5-6% to maintain your margin. Calculate it per dish for the most accurate results.
Will I lose customers if I raise prices?
Small, regular adjustments (2-3% at a time) are less noticeable than one big 10% jump. Communicate honestly about cost increases - most guests understand this reality.
What's the biggest mistake restaurants make with pricing?
Waiting too long to adjust prices, then having to make dramatic increases all at once. This shocks customers and often leads to lost business that gradual increases would've avoided.
