How can you tell from your numbers that your prices are...

Quick answer
Every quarter, restaurant owners miss thousands in profit because their prices haven't caught up with rising costs. Suppliers bump their rates 2-3 times yearly, yet many menus still reflect last year's numbers.

Every quarter, restaurant owners miss thousands in profit because their prices haven't caught up with rising costs. Suppliers bump their rates 2-3 times yearly, yet many menus still reflect last year's numbers. Here are the warning signs your pricing needs an immediate update.

Signal 1: Your food cost is rising without a clear reason

The most obvious warning sign? Rising food cost percentages. If you haven't touched your recipes or portions, but food cost jumps from 30% to 35%, your purchase prices have increased while selling prices stayed flat.

? Example:

Your steak had a food cost of 32% last year:

  • Ingredients: €9.60
  • Selling price: €30.00 excl. VAT
  • Food cost: 32%

Now the same meat costs €12.00, but you're still selling it for €30.00:

  • Ingredients: €12.00
  • Selling price: €30.00 excl. VAT
  • Food cost: 40%

You're now losing €2.40 per steak compared to last year.

Signal 2: Your profit is declining despite stable revenue

Same guest count. Same average check size. But profit keeps shrinking? That's your margins bleeding out. From analyzing actual purchasing data across different restaurant types, this pattern shows up most clearly in monthly comparisons.

  • Same number of guests as last year
  • Same average bill amount
  • But less profit left over

Check your total monthly food cost percentage. Has it crept from 30% to 34%? Your margins are evaporating dish by dish.

Signal 3: Your competitors can offer cheaper prices

If nearby restaurants serve comparable dishes at lower prices, two scenarios are possible: they've secured better supplier deals, or you haven't adjusted prices while they have. Neither scenario favors you.

⚠️ Note:

Don't just compare menu prices, but also portion size and quality. A cheaper competitor might use smaller portions or different ingredients.

Signal 4: Your supplier raised prices, you didn't

Suppliers send updated price lists regularly. Many owners delay menu updates, fearing customer backlash. But your margin disappears faster than customers do.

? Example calculation:

Your supplier raised beef from €18 to €22 per kilo (+22%). You sell 100 steaks of 250 grams per week:

  • Extra cost per steak: €1.00
  • Per week: €100 extra costs
  • Per year: €5,200 less profit

If you don't adjust your price, you lose €5,200 per year on this one dish.

How often should you check your prices?

Review your food costs quarterly minimum. Focus on your 5 top-selling dishes first - they drive 80% of revenue. Get those right, and you've fixed most problems.

  • Monthly: Total food cost of your restaurant
  • Per quarter: Food cost of your top dishes
  • When prices change: Calculate immediately for your menu

The psychology behind prices that are too low

Fear of customer exodus keeps many owners from raising prices. But you're walking away from profit while customers barely notice modest increases. A €2 bump per dish often flies under the radar, yet generates thousands annually.

? Calculation example:

You sell 50 main courses per day, 6 days a week. A price increase of €2 per dish:

  • Per day: €100 extra revenue
  • Per week: €600 extra revenue
  • Per year: €31,200 extra revenue

Even if 10% of your customers stay away, you still keep €25,000 per year.

How do you check if your prices are still correct? (step by step)

1

Calculate your current food cost

Take your 5 best-selling dishes. Add up all ingredient costs and divide by your selling price excl. VAT. Multiply by 100 to get the percentage.

2

Compare with last year

Check if your food cost is higher than 12 months ago. An increase of more than 2 percentage points often means your prices are falling behind.

3

Calculate new selling prices

For any food cost above 35%: divide your ingredient costs by 0.30 for a healthy margin of 30%. Multiply by 1.09 for the price incl. VAT.

✨ Pro tip

Track food cost percentages on your top 3 dishes every 6 weeks. If any dish hits 36% or higher, you've waited too long to adjust pricing.

Frequently asked questions

What is an acceptable food cost for restaurants?
Between 28% and 35% is standard for most establishments. Above 35% you're probably losing money on that dish, below 25% you might be able to offer more competitive prices.
How do I prevent customers from leaving when I raise prices?
Increase gradually (€1-2 at a time), improve your service or presentation simultaneously, and don't announce the increase - just put out new menus. Most customers won't even notice modest adjustments.
How do I quickly calculate what a new price should be?
Divide your ingredient costs by 0.30 for 30% food cost, or by 0.28 for 28% food cost. Then multiply by 1.09 for the price including VAT.
