Most restaurant owners believe inventory costs are just the price of doing business. That's wrong. Your inventory represents cash sitting in coolers and storage cabinets, and many operators have no clue if they're tying up too much capital in unused stock.
What exactly are inventory costs?
Inventory costs represent the total cash you've invested in ingredients that haven't been sold yet. This includes everything in your cooler, freezer, dry storage and bar waiting to be transformed into revenue.
💡 Example bistro inventory:
A bistro with €400,000 annual revenue has:
- Meat and fish in cooler: €2,800
- Vegetables and dairy: €1,200
- Dry storage (pasta, rice, spices): €800
- Beverages (wine, beer, soft drinks): €1,500
- Other products: €700
Total inventory value: €7,000
The calculation: inventory as a percentage of revenue
You need to know if your inventory levels are normal by calculating them as a percentage of annual revenue. Here's the formula:
Inventory costs % = (Current inventory value / Annual revenue) × 100
💡 Calculation example:
Bistro from previous example:
- Inventory value: €7,000
- Annual revenue: €400,000
- Calculation: (€7,000 / €400,000) × 100 = 1.75%
This falls within the normal range of 1-3% for restaurants.
What is a normal inventory value?
Your ideal inventory value depends on business type and ordering frequency. From analyzing actual purchasing data across different restaurant types, here are typical percentages:
- Restaurants and bistros: 1.5-3% of annual revenue
- Fast casual and delivery: 1-2% of annual revenue
- Fine dining: 2-4% of annual revenue (more fresh products)
- Cafés with kitchen: 1-2.5% of annual revenue
⚠️ Watch out:
If you're above 4%, you're probably holding too much inventory. This costs you money through spoilage and tied-up capital.
Why too much inventory is dangerous
High inventory values create three profit-killing problems:
- Tied-up money: Every euro in inventory can't be invested in marketing or renovations
- Spoilage and waste: More inventory means higher risk of throwing products away
- Cash flow problems: You'll have less money available for daily expenses
💡 Impact calculation:
Restaurant with €500,000 annual revenue:
- Normal inventory (2.5%): €12,500
- Too high inventory (5%): €25,000
- Difference: €12,500 tied-up capital
That money works better for growth or as a buffer.
How often should you check this?
Check your inventory value at least monthly, ideally every two weeks. You'll spot trends and can adjust before problems spiral out of control.
Many operators use tools like KitchenNmbrs to track ingredients and prices, so they can quickly see inventory value without manual counting sessions.
How do you calculate inventory costs as a percentage? (step by step)
Add up your complete inventory value
Go through all storage locations: cooler, freezer, dry storage, bar. Add up all products at purchase price. Don't forget spices, oil, cleaning supplies and other small items.
Determine your annual revenue
Use your revenue from the past 12 months. If you're seasonal, take a full year to get an accurate picture.
Calculate the percentage
Divide your inventory value by your annual revenue and multiply by 100. The result gives you the percentage. Compare this with the benchmarks for your type of business.
✨ Pro tip
Calculate your inventory percentage on the same day each month, preferably Monday mornings before major deliveries arrive. This gives you consistent data points you can track over the next 6 months to spot trends.

Frequently asked questions
Should I include VAT in the calculation?
No, calculate using purchase prices excluding VAT. Your inventory cost you those amounts, and you'll get the VAT back through your tax return.
What if my percentage is higher than the benchmark?
Then you're probably holding too much inventory. Order less frequently, check your FIFO system and see if you have products about to expire.
How often should I count my inventory?
For accuracy, count everything. For quick checks, focus on expensive items: meat, fish and premium ingredients. That covers roughly 70% of your total value.
Does wine inventory count too?
Yes, all beverages you sell count as inventory. Wine can represent a large portion of inventory value, especially in fine dining establishments.
Is 1% inventory costs too low?
Not necessarily. If you buy fresh daily and maintain minimal dry storage, 1% can be normal. Just ensure you're not over-ordering, as frequent deliveries waste time.
What about seasonal fluctuations in inventory costs?
Seasonal variations are normal - holiday periods and special events often require higher stock levels. Track your percentage over 12 months to see your true average.
