A €200 vegetable order from your supplier just became €221 after delivery fees, fuel surcharges, and administrative costs got added on. Most restaurant owners ignore these extras and wonder why their food costs keep climbing. Here's how to calculate your true purchase prices.
What are delivery costs and why include them?
Delivery costs are all extra charges your supplier adds on top of product prices. These aren't just direct transport costs, but also administrative fees, minimum order surcharges, and fuel surcharges.
💡 Example:
You order €200 worth of vegetables from your supplier:
- Product value: €200
- Delivery costs: €15
- Administrative costs: €2.50
- Fuel surcharge: €3.50
Actual purchase price: €221 (10.5% more expensive)
Ignoring these costs in your calculations is a mistake that costs the average restaurant EUR 200-400 per month. Your food cost percentages look better on paper, but your profits disappear faster than expected.
Different types of supplier costs
Suppliers charge multiple cost items. You need to spot them all:
- Delivery costs: Fixed costs per delivery (€10-25)
- Fuel surcharge: Percentage of order value (1-3%)
- Administrative costs: Fixed costs per order (€1-5)
- Minimum order surcharges: Extra costs for small orders
- Refrigerated transport surcharge: Extra for chilled delivery
- Express delivery: Higher costs for rush orders
⚠️ Heads up:
Some suppliers don't clearly list these costs on the invoice. Always check your supplier contract and demand transparency in all cost items.
Formula for actual purchase price
The basic formula is straightforward, but you must include every cost item:
Actual purchase price = (Product value + All surcharges) / Number of products
Use this actual purchase price in your recipes, not your supplier's catalog price. Otherwise, you're calculating with fantasy numbers.
💡 Example calculation:
You order 20 kg of beef at €18/kg:
- Product value: 20 kg × €18 = €360
- Delivery costs: €20
- Fuel surcharge (2%): €7.20
- Administration: €3
Total costs: €390.20
Actual price per kg: €390.20 / 20 = €19.51/kg
Impact on your food cost
That €1.51 per kg difference seems tiny. But it's not. For a 250-gram steak, this costs you an extra €0.38 per portion.
Sell 100 steaks per week? You're losing €1,976 per year by calculating with €18/kg instead of €19.51/kg. And that's just one ingredient.
How to organize this in practice
Most restaurant owners only update purchase prices when suppliers raise product prices. But delivery costs change regularly due to fuel prices and labor costs.
- Update your actual purchase prices monthly
- Keep invoices and factor in all surcharges
- Compare different suppliers on total costs, not just product prices
- Negotiate delivery costs for large orders
💡 Practical tip:
Create an Excel sheet with your top 20 ingredients and calculate the actual purchase price monthly. Or use food cost tools that automatically factor all costs into your recipes.
Compare suppliers on total costs
Many entrepreneurs pick suppliers based on product price alone. Supplier A with lower product prices could cost more due to high delivery fees.
💡 Comparison:
Supplier A vs B for the same €300 order:
Supplier A:
- Product value: €300
- Delivery costs: €25
- Total: €325
Supplier B:
- Product value: €315
- Delivery costs: €8
- Total: €323
Supplier B is €2 cheaper despite higher product prices
Digital vs manual tracking
You can track this manually in Excel, but it's time-consuming and error-prone. Modern hospitality apps automatically factor all surcharges into your cost prices.
The advantage of digital systems: set up your supplier costs once. After that, all your recipes get automatically updated with actual purchase prices.
How do you calculate the actual purchase price? (step by step)
Collect all cost items from your invoice
Note not just the product value, but also delivery costs, fuel surcharges, administrative costs, and other surcharges. Check your supplier contract for fixed cost items that don't always appear on the invoice.
Add up all costs for the total order value
Sum the product value plus all surcharges. This is your actual total purchase costs for this delivery. Don't forget any cost item, no matter how small.
Calculate the actual price per unit
Divide the total costs by the number of units (kg, pieces, liters). This is the price you should use in your cost price calculations, not your supplier's catalog price.
✨ Pro tip
Calculate actual purchase prices for your 15 most expensive ingredients every 6 weeks. These items typically represent 80% of your food costs, so accuracy here has the biggest financial impact.

Frequently asked questions
How often should I update my actual purchase prices?
At least monthly, or every time your supplier adjusts delivery costs. Fuel surcharges can change weekly with some suppliers.
Can I negotiate delivery costs with my supplier?
Absolutely, especially for large or frequent orders. Ask for discounts on minimum orders or fixed delivery days. Some suppliers offer free delivery above certain order amounts.
What if my supplier doesn't clearly specify the costs?
Demand a detailed invoice with all cost items listed separately. This is your right as a customer and essential for calculating correct cost prices.
Do small delivery costs really make that much difference?
€10 delivery costs on a €200 order means 5% higher purchase costs. With annual revenue of €500,000, this can create thousands of euros difference in your profitability.
