Picture this: your signature dish quietly went from profitable to break-even over three months, and you never noticed. Supplier costs fluctuate, seasons shift, and your margins erode quietly. Without a scheduled review system, you're bleeding profit without realizing it.
Why scheduling matters more than you think
Most restaurant owners react to margin problems instead of preventing them. By then, damage is done. That ribeye sitting at 30% food cost last month? It's probably hitting 38% now because your butcher raised prices twice.
⚠️ Watch out:
Irregular margin checks cost restaurants 3-5% profit annually. On €400,000 revenue, that's €12,000-€20,000 vanishing.
Monday mornings work for a reason
Smart operators pick Monday morning for their margin review. Here's why this timing clicks:
- Restaurant's typically closed or slow
- Weekend sales data is fresh in your mind
- You can adjust orders for the upcoming week
- Suppliers answer phones and provide updated pricing
Focus on what drives revenue
Don't check everything – target your 5-7 bestsellers. These dishes generate roughly 70% of your income:
💡 Sample review:
- Ribeye: jumped from 32% to 35% food cost (beef prices up)
- Salmon special: climbed from 28% to 31% (fish market volatility)
- Carbonara: holding steady at 26%
- Caesar salad: rose from 22% to 24% (lettuce shortage)
Decision: Bump ribeye and salmon by €2 each.
Your 30-minute system
Effective margin reviews don't require hours. Here's something most kitchen managers discover too late – structure saves time:
- Minutes 1-10: Gather current supplier pricing
- Minutes 11-20: Recalculate food costs for top performers
- Minutes 21-25: Identify which items need price adjustments
- Minutes 26-30: Update menus or flag changes for implementation
Red flags that demand action
Not every cost increase requires menu changes. But watch for these triggers:
💡 Act when:
- Food cost exceeds 35% (standard threshold)
- Margins drop 2+ percentage points
- Ingredient costs spike 10%+ in one month
- Weekly profit shrinks despite steady sales
Beyond raising prices
Menu price increases aren't your only option. Consider these moves:
- Trim portions slightly: 200g steak instead of 220g
- Swap expensive sides: Roasted potatoes replace truffle fries
- Shop around: Compare 2-3 suppliers monthly
- Seasonal adjustments: Remove high-cost items temporarily
⚠️ Watch out:
Portion cuts over 10% get noticed by guests. You'll face complaints and potential reputation damage.
Manual tracking vs. automated systems
Excel works, but it's time-consuming and error-prone. Tools like KitchenNmbrs automatically recalculate food costs when you update ingredient prices. You instantly see which dishes breach your thresholds.
The benefit: no manual calculations, no formula errors, no VAT confusion.
How do you set up a weekly margin check?
Choose your fixed moment
Grab your calendar and block off every Monday morning from 9:00-9:30. Set it as a recurring appointment. Treat it like an important meeting you don't cancel.
Make a checklist of your top dishes
Write down your 5-7 best-selling dishes. Note the current food cost and your limit (usually 35%). This becomes your fixed list to check.
Check and adjust
Check whether purchase prices have changed. Calculate the new food cost. Above your limit? Then adjust your menu price or look for alternatives like smaller portions.
✨ Pro tip
Block 30 minutes every Monday at 9 AM specifically for margin review – treat it like a client meeting you can't reschedule. This single habit protects more profit than most operators realize.
Calculate this yourself?

Frequently asked questions
How often should I adjust my menu prices?
Most dishes need adjustment 1-2 times quarterly. Seasonal ingredients require more frequent changes, while stable items like pasta stay consistent longer.
What if customers push back on price increases?
Stagger increases instead of raising everything simultaneously. Most guests understand inflation affects restaurants too. Emphasize that quality remains unchanged.
Should I review all menu items or just popular dishes?
Start with your 5-7 bestsellers since they drive 70% of revenue. Review remaining items monthly rather than weekly to save time.
Is 35% food cost the right target for every restaurant?
It's a solid baseline for most operations. Fine dining can run 38%, while fast-casual should target 25-30%. Focus on what you actually keep as profit.
Can I delegate this review to my chef or manager?
Your chef can gather data and run calculations, but pricing decisions affect your bottom line directly. Stay involved in the final calls.
What if I can't commit to weekly reviews?
Monthly reviews are better than nothing, but you risk larger profit leaks. Thirty minutes weekly often prevents hundreds in monthly losses.
How do I track supplier price changes effectively?
Ask suppliers for advance notice of increases when possible. Keep a simple log of key ingredient costs and compare month-over-month for trends.
