A supplier raises beef prices by 15%, but nobody adjusts the recipe. Every steak you sell now costs €3 more, while your menu price stays the same. After a month you notice your profit has disappeared, but you don't know why.
How price increases eat away at your margin
This scenario plays out in restaurants everywhere: your supplier sends notice that prices jump on January 1st. That notice gets buried under invoices and order sheets. Nobody touches the recipes. For months, you're selling dishes without realizing they've gotten way more expensive.
💡 Example:
Your steak recipe from January:
- Steak 250g: €6.00 (was €24/kg)
- Sides and sauces: €2.50
- Total food cost: €8.50
Menu price €32 (excl. VAT €29.36) = food cost 29%
March rolls around and your supplier bumps beef to €28/kg. But nobody touches that recipe in your system.
💡 Actual costs in March:
- Steak 250g: €7.00 (now €28/kg)
- Sides and sauces: €2.50
- Actual food cost: €9.50
Actual food cost: 32.4% - you lose €1 per steak
The hidden damage on an annual basis
Sure, it's only €1 per dish. But that damage compounds fast. Sell 3 steaks daily, 6 days weekly? You're bleeding €936 yearly on one dish alone. And this hits multiple ingredients simultaneously.
⚠️ Watch out:
Suppliers don't just bump meat prices. Vegetables, dairy, oil and wine climb regularly too. Skip updating 10 recipes and you're looking at €5,000+ in annual losses.
Why this happens so frequently
The issue isn't your chef or buyer - it's systemic:
- No central recipe database: Recipes live in different notebooks or your chef's memory
- Purchasing and recipes don't talk: Your buyer can't tell which recipes need adjusting
- No regular audits: Nobody verifies if food costs stay accurate
- Daily operations consume everything: Recipe updates never make the priority list
The domino effect on your entire menu
Outdated recipes lead to terrible decisions. From years of working in professional kitchens, I've seen this pattern destroy profit margins across entire menus.
💡 Example domino effect:
You think your steak runs 29% food cost (profitable). So you:
- Push it as your signature dish
- Give it prime menu real estate
- Hold off raising other prices
- Order more beef
While you're actually running 32.4% food cost and losing money per plate.
How to prevent this
You need a system where recipes and purchase prices connect:
- Central ingredient database: All prices in one spot, linked to every recipe using that ingredient
- Automatic recalculation: Adjust beef price and all beef recipes recalculate instantly
- Monthly audits: Verify your key ingredients still carry correct pricing
- Alert system: Get flagged when dishes exceed target food costs
With tools like KitchenNmbrs you instantly spot which dishes got more expensive and can decide whether to adjust menu pricing or tweak the recipe.
How do you prevent margin loss from price increases?
Make a list of your 10 most important ingredients
Check which ingredients appear most in your recipes and have the largest share of your purchasing costs. Think of meat, fish, vegetables, dairy and oil.
Set up a monthly price check
Check every month whether the prices of these ingredients still match your supplier invoices. Pay special attention after January (often price increases) and after seasonal changes.
Update recipes immediately after price changes
As soon as you discover a price increase, update all recipes that contain this ingredient. Calculate the new food cost and decide whether your menu price needs to be adjusted.
✨ Pro tip
After every supplier invoice, make this your routine: check invoice, compare prices, update recipes within 48 hours. This prevents price increases from silently destroying your margins.

Frequently asked questions
How often do suppliers raise their prices?
Typically 1-2 times yearly, often in January. Meat and dairy fluctuate more frequently due to market conditions. Vegetables shift seasonally.
Should I raise my menu price immediately with every price increase?
Not necessarily. First verify if your food cost remains acceptable. Under 35% usually works fine. Above 35% signals time for menu price adjustments.
Can't I just add a 10% markup to all ingredients?
That's wildly inaccurate. Different ingredients rise by different percentages - beef might jump 15% while potatoes climb 5%. You need ingredient-specific tracking.
What if I don't have time to update all recipes?
Focus on your 5 top sellers first - they drive the biggest profit impact. Update others gradually or invest in a system that handles this automatically.
