A weekly KPI overview puts you in complete control of your kitchen operations in just 60 minutes per week. Most restaurant owners obsess over revenue while critical indicators like food cost, waste patterns, and operational efficiency slip through the cracks. A focused dashboard of 5-7 key metrics instantly reveals which areas are performing well and which demand immediate attention.
The 7 most important KPIs for your weekly overview
Skip the data overload. These 7 metrics deliver maximum insight with minimum effort:
- Revenue per square meter of kitchen - measures your efficiency
- Average food cost % - keeps your margins in check
- Covers per hour of staff - shows your productivity
- Waste as % of purchases - leaks directly from your profit
- Average check value - trends in spending behavior
- Inventory turnover (days) - prevents capital getting stuck
- Break-even point per day - how much you need to turn to break even
💡 Example:
Restaurant De Smaak, 40 seats, week 12:
- Revenue: €8,200
- Food cost: 31% (€2,542)
- Covers: 280
- Waste: €180 (7% of purchases)
- Average check: €29.30
Signal: waste too high (aim for 5%)
How do you calculate these KPIs practically?
Your POS system and supplier invoices contain everything you need. Here's how to crunch the numbers:
Food cost percentage
Formula: (Total purchase costs / Revenue excl. VAT) × 100
💡 Example:
Weekly revenue: €8,200 incl. VAT
- Revenue excl. VAT: €8,200 / 1.09 = €7,523
- Ingredient purchases: €2,300
- Food cost: (€2,300 / €7,523) × 100 = 30.6%
Inventory turnover
Formula: Inventory value / (Weekly purchases / 7)
This reveals how many days your inventory will last. Target 3-7 days for fresh ingredients.
⚠️ Note:
Count inventory at identical times each week. Monday morning before service works well. Inconsistent timing makes your data worthless.
Setting up your weekly routine
Transform your KPI review into a sacred Monday morning ritual. Most successful operators follow this 60-minute schedule:
- 9:00 - 9:15: Extract POS data (revenue, covers, average check)
- 9:15 - 9:30: Total last week's supplier invoices
- 9:30 - 9:45: Count inventory (focus on your 10 priciest ingredients)
- 9:45 - 10:00: Estimate waste (what hit the garbage?)
That single hour often prevents hundreds in weekly losses. Something most kitchen managers discover too late after bleeding money for months.
Recognizing signals and taking action
Your metrics only matter if you act on warning signs:
💡 Action signals:
- Food cost > 35%: Audit your 5 top-selling dishes for cost accuracy
- Waste > 8%: Identify what's being discarded and root causes
- Inventory > 10 days: Reduce orders, prioritize fast-moving items
- Average check declining: Investigate if guests are skipping sides/desserts
Digital vs. manual tracking
Excel works but eats time and breeds errors. Smart operators use systems that automatically calculate:
- Food cost per dish and overall
- Cost impact from supplier price changes
- Recipe-based inventory valuations
- Week-over-week comparisons
The payoff: spot problems instantly without manual calculations.
How to set up your weekly KPI overview
Gather your basic data
Get from your POS system: total revenue, number of covers and average check value from last week. Add up all supplier invoices for your total purchases. These are your starting figures.
Calculate your food cost percentage
Divide your total purchase costs by your revenue excluding VAT and multiply by 100. At 9% VAT: revenue divided by 1.09 = excl. VAT. Aim for 28-35% food cost.
Count your inventory value
Estimate the value of your refrigeration, freezer and dry storage. Focus on your 10-15 most expensive ingredients, that gives 80% of your inventory value. Divide by your daily purchases for turnover speed.
Record waste and loss
Estimate what was thrown away: spoiled products, failed dishes, over-prepped items. Convert this to euros and divide by your total purchases for waste percentage.
Compare with previous weeks
Put your figures next to week -1, -2 and -4. Look for trends: is your food cost rising structurally? Is your average check declining? Major deviations call for action this week.
✨ Pro tip
Track food cost on your 3 highest-volume dishes every Monday morning for 4 weeks straight. These dishes typically represent 60-70% of your profit impact, making weekly monitoring far more valuable than monthly deep-dives.

Frequently asked questions
Which KPI deserves the most attention in my weekly review?
Food cost percentage. This metric instantly reveals if your dishes remain profitable after supplier price increases. You'll catch margin erosion before it devastates your bottom line.
How precise does my inventory count need to be for reliable KPIs?
Focus on your 10-15 most expensive ingredients for weekly tracking. But consistency matters more than precision - count at the exact same time each week, like Monday morning before service.
What if my KPIs swing wildly week to week?
Completely normal for smaller operations. Track 4-6 week trends instead of obsessing over single weeks. One bad week might be coincidence, but three weeks of declining margins demands action.
Should labor metrics be part of my weekly KPI routine?
Keep it simple: covers per staff hour shows team efficiency clearly. Save complex labor cost analysis for monthly reviews to avoid overwhelming your weekly routine.
My weekly KPI setup is taking 2+ hours - what am I doing wrong?
You're tracking too many metrics or working too manually. Stick to 5-7 core KPIs and consider automated tools if manual calculations are eating your time.
At what threshold should my KPIs trigger immediate action?
Food cost above 35%, waste exceeding 8%, or inventory lasting more than 10 days need immediate attention. But also watch trends - three consecutive weeks of rising food costs at 32% still demands investigation.
