Weekly cost price reviews keep your team focused on the numbers that matter. Most restaurants handle this sporadically, letting costly errors accumulate over time. A structured routine prevents months of unknowingly operating at reduced margins.
Why consistent cost price monitoring delivers results
Suppliers bump their prices constantly. Sometimes 5%, sometimes 15%. Skip weekly checks and you'll fall behind fast. You're selling dishes thinking they run 30% food cost, but they've crept up to 38%.
💡 Example:
Your steak cost breakdown last month:
- Steak 200g: €7.20
- Sides and sauce: €1.80
- Total ingredients: €9.00
Selling price €32.00 (excl. VAT €29.36) = 30.7% food cost
But your supplier raised beef by 12%. Now that same steak costs €8.06. Your new cost price hits €9.86, jumping to 33.6% food cost. Each steak now loses an extra €0.86 - a mistake that costs the average restaurant EUR 200-400 per month across their menu.
Your 4-step weekly cost review system
Lock in a specific time. Monday mornings at 10:00 work well, before the week gets chaotic. Block out 30-45 minutes and protect it.
💡 Example routine:
Restaurant The Golden Spoon runs this every Monday:
- 10:00-10:15: Review supplier invoices from previous week
- 10:15-10:30: Update changed ingredient prices
- 10:30-10:45: Recalculate cost price of top 5 dishes
- 10:45-11:00: Determine which menu prices need adjustment
Your team learns that Monday morning means 'numbers time'. No deliveries scheduled, no competing meetings. This takes priority.
Team roles and responsibilities
Split the workload. The owner doesn't need to handle everything:
- Sous-chef or kitchen manager: Gathers all supplier invoices
- Owner or manager: Updates prices in tracking system
- Both together: Review dishes exceeding 35% food cost
- Owner: Makes final call on menu price changes
⚠️ Note:
Get your kitchen team involved with the numbers. Once they understand why a steak portion should be 200 grams (not 250 grams), they'll work with better precision.
Which dishes deserve your attention
Target your top 5 revenue drivers. They represent 60-70% of your food sales. Get those numbers right and you've tackled the bulk of your challenge.
💡 Example prioritization:
Bistro The Square weekly sales:
- Steak: 45 portions (€1,440 revenue)
- Salmon: 38 portions (€950 revenue)
- Pasta carbonara: 52 portions (€936 revenue)
- Goat cheese salad: 28 portions (€560 revenue)
- Spare ribs: 22 portions (€550 revenue)
These 5 dishes = €4,436 of total €6,200 food revenue (71%)
Also monitor dishes with premium ingredients (lobster, truffle, wagyu) and new menu items where you're still learning the true costs.
Building the habit that sticks
Habits form through repetition and clear rewards. Make it simple and visible:
- Same schedule: Identical day, time, every single week
- Dedicated space: Office or quiet area, never in the kitchen during service
- Calendar block: Treat it like an unmovable appointment
- Visual tracking: Post your food cost summary in the office
After 4-6 weeks it becomes automatic. Your team expects it as part of regular operations, like cleaning and inventory counts.
Digital tracking tools
Excel works initially but gets messy fast. Food cost calculators like KitchenNmbrs automatically update your percentages when ingredient prices change. You instantly spot which dishes exceed your target margins.
⚠️ Note:
Any system only works with accurate data input. Skip updating ingredient prices and you'll get misleading cost calculations.
Acting on your findings
Cost reviews mean nothing without follow-through. Set clear action thresholds:
- Food cost above 35%: Increase menu price or modify recipe
- Food cost 32-35%: Monitor closely, no immediate action needed
- Food cost below 28%: Consider upgrading ingredients or portion sizes
Document every decision. Record why you changed a price so your team understands the reasoning and can explain it to customers.
How do you start a weekly cost price routine? (step by step)
Schedule a fixed time
Choose a day and time when you have peace and quiet. Monday morning works well: you have all invoices from last week and can start the new week right. Put it in your calendar as an appointment.
Gather all supplier invoices
Collect all invoices from the past week. Check which ingredients have gone up or down in price. Start by focusing on your main suppliers (meat, fish, vegetables).
Update prices of changed ingredients
Update the ingredient prices in your system. Start with ingredients that are used a lot (oil, butter, onion, meat). These have the biggest impact on your total cost price.
Calculate new food cost of top 5 dishes
Check your 5 best-selling dishes. Which ones now exceed 35% food cost? Those are your priority for price adjustment or recipe change.
Make decisions and communicate
Decide which menu prices you're adjusting. Explain this to your team so they understand why a price is going up. Guests accept price increases better when staff can explain them.
✨ Pro tip
Schedule your weekly review for the same 45-minute window every Monday at 10 AM for the next 8 weeks. After 2 months, this timing becomes non-negotiable for your entire team.

Frequently asked questions
What if my team resists doing weekly cost reviews?
Start with just your 3 highest-revenue dishes and keep it to 15 minutes initially. Once they see how price creep affects profits, they'll understand the value. Make it part of their regular responsibilities, not an extra burden.
Should I adjust menu prices immediately when food costs spike?
If your food cost jumps above 35%, yes - take action within the week. You can either raise the menu price or modify the recipe with smaller portions or alternative ingredients. Waiting longer just increases your losses.
How do I handle seasonal ingredient price swings?
Build seasonal price variations into your planning. Track the same ingredients over 12 months to spot patterns. Consider seasonal menu changes or temporary price adjustments during peak cost periods like asparagus season or holiday protein demands.
