What steps do you take when your food cost percentage is good, but your gross margin in euros stays too low?

📝 KitchenNmbrs · updated 16 Mar 2026

A perfect 30% food cost percentage won't save you from losing money if your other costs are bleeding cash. The real culprit is usually hiding in your staff costs, rent structure, or average check size. Here's how to find where your euros are disappearing and fix it fast.

Why good food cost percentages can mask bigger problems

Food cost at 30% sounds great - that's 30 cents per euro going to ingredients. But what about the remaining 70 cents? It's got to cover staff wages, rent, utilities, equipment, and your profit. When that 70 cents falls short, you're in trouble despite hitting your food cost targets.

💡 Example:

Restaurant with 30% food cost, but operating at a loss:

  • Revenue: €100,000/month
  • Food cost: €30,000 (30%)
  • Staff costs: €45,000 (45%)
  • Other costs: €20,000 (20%)
  • Profit: €5,000 (5%)

Food cost is fine, but staff costs are too high for this revenue level.

Break down your complete cost structure

You need to examine every cost category as a revenue percentage. Based on real restaurant P&L data from over 200 establishments, here's what healthy percentages look like:

  • Food cost: 28-35%
  • Staff costs: 28-35%
  • Rent costs: 6-10%
  • Energy costs: 3-6%
  • Other costs: 8-12%
  • Profit before tax: 8-15%

If any single percentage climbs too high, you'll lose money even with perfect food cost control.

⚠️ Watch out:

Staff costs above 38% spell trouble, unless you're running a high-end concept where exceptional service justifies the expense.

Examine your average check size

Low gross margins often stem from guests who simply don't spend enough per visit. Your fixed costs remain the same whether someone orders a €15 main or a €35 three-course meal.

💡 Example calculation:

Situation: 100 covers per day, €2,000 revenue

  • Average check: €2,000 ÷ 100 = €20.00
  • For break-even you need €25.00
  • Shortfall: €5.00 per guest
  • Daily loss: 100 × €5.00 = €500

Solution: increase check size to €25.00 or lower costs.

Boost your average check without hurting food cost

Several tactics can drive more revenue per guest while maintaining your food cost percentage:

  • Upselling training: Teach staff to suggest appetizers and desserts naturally
  • Beverage focus: Wine pairings and signature cocktails carry high margins
  • Menu engineering: Position profitable dishes prominently
  • Portion options: Offer small and large sizes for flexibility

Streamline your staff deployment

After food, labor typically represents your biggest expense. Scrutinize your staffing patterns:

  • How many staff do you actually need during slow periods?
  • Can you cross-train employees to handle multiple roles?
  • Are you scheduling based on actual demand patterns?

💡 Practical example:

By having 1 fewer staff member during lunch service:

  • Savings: €120 per day (8 hours × €15/hour)
  • Per month (25 working days): €3,000
  • Per year: €36,000 extra profit

Raise prices strategically

Good food cost percentages give you pricing flexibility. Target your most popular dishes with the lowest ingredient costs first.

⚠️ Watch out:

Avoid blanket price increases. Test incremental changes on high-volume items and monitor customer response carefully.

Track your break-even point

Know exactly how many covers you need daily to cover all expenses. Falling consistently below this number means immediate action is required.

Formula for break-even covers per day:

(Fixed costs per day) ÷ (Average check - Variable costs per check)

Step-by-step plan: From good food cost to healthy profit

1

Analyze all cost items

Calculate each cost type as a percentage of your revenue: food, staff, rent, energy, other. Compare with the benchmarks in this article to see where the problem is.

2

Calculate your average check size

Divide your daily revenue by the number of covers. Check if this is enough to cover your fixed costs. If not, you need to increase check size or lower costs.

3

Choose your strategy

Increase check size through upselling and menu engineering, optimize staff deployment, or selectively raise prices. Combine multiple tactics for maximum effect.

✨ Pro tip

Run a 6-week test reducing lunch staff by one person while tracking service quality scores. If scores stay above 4.2/5, you've found €18,000 in annual savings without compromising the guest experience.

Frequently asked questions

My food cost is 28%, so why am I not making money?

Low food cost doesn't guarantee profit. Your staff costs might be above 35%, or your average check size could be too low to cover fixed expenses. Examine every cost category as a percentage of revenue.

Can I raise my prices without losing customers?

Yes, but do it strategically. Start with your most popular dishes that have low food costs. Increase by €1-2 and monitor customer reaction before making further changes.

How do I calculate my break-even point?

Divide your daily fixed costs by your average margin per guest (check size minus variable costs). This gives you the minimum covers needed to avoid losses.

What if my staff costs are consistently above 35%?

Look at flexible scheduling during quiet periods, cross-train employees for multiple roles, and evaluate whether all positions are necessary during every service. Even reducing one staff member during slow times can save €36,000 annually.

How do I increase my average check size effectively?

Train staff in natural upselling techniques, create attractive wine pairings, offer different portion sizes, and use menu engineering to highlight profitable dishes. Focus on beverages since they typically have the highest margins.

Should I focus on food cost or other costs first?

If your food cost is already good, tackle your largest expense category first - usually staff costs. A 3% reduction in staff costs often has more impact than perfecting an already decent food cost percentage.

How often should I review my cost structure percentages?

Check all major cost categories weekly as revenue percentages. Monthly reviews are too late to catch problems before they seriously damage profitability.
