Most cooking instructors drastically undercharge because they think like home cooks, not business owners. Private workshops involve way more than ingredient costs - there's transport, prep time, demo portions, and equipment hauling. The real formula accounts for every hidden expense that'll eat your profits.
What makes cooking workshops different?
Private workshops aren't restaurant service. You're hauling everything from your base kitchen to someone else's space, which creates costs most instructors ignore.
- Ingredients must be pre-purchased and transported fresh
- Your actual work time extends far beyond the workshop hours
- Demo portions require 25-30% more ingredients than guest portions
- Fuel, parking, and vehicle wear add up fast
The real cost price formula for cooking workshops
Profitable workshops require this calculation:
Cost price = Ingredients + Transportation + Preparation + Extra materials
💡 Example:
Pasta workshop for 6 people, 3 courses:
- Ingredients: €45.00
- Transportation (30 km round trip): €8.50
- Preparation at home (2 hours at €25): €50.00
- Extra ingredients for demo: €12.00
Total cost price: €115.50
Calculating ingredients accurately
Don't just count guest portions. After managing kitchen operations for nearly a decade, I've learned you need extras for:
- Demonstration: 20-30% extra for step-by-step examples
- Mistakes: 10-15% buffer for kitchen accidents
- Instructor tasting: You need to taste and adjust seasoning throughout
⚠️ Note:
Always calculate 25% extra ingredients for demonstration and unforeseen issues. Running short mid-workshop kills your credibility instantly.
Transportation costs aren't optional
Many instructors eat these costs, but they're legitimate business expenses:
- Mileage allowance: €0.28 per kilometer (don't forget the return trip)
- Parking fees: Urban locations often require paid parking
- Vehicle wear: Extra trips mean accelerated maintenance schedules
Time calculation: beyond workshop hours
A 3-hour workshop actually consumes your entire day:
💡 Example time breakdown:
- Shopping: 1.5 hours
- Home preparation: 2 hours
- Transportation: 1 hour
- Workshop delivery: 3 hours
- Cleanup and return: 1 hour
Total: 8.5 hours of work
Calculate minimum €20-25 per hour for prep work. You're running a business, not doing charity work.
Converting cost price to selling price
Cost price is just your starting point. For sustainable margins you need:
Selling price = Cost price × 2.5 to 3
This markup covers:
- Unexpected cost overruns
- Sick days and cancellations
- Marketing and client acquisition
- Actual profit for your living expenses
💡 Example selling price:
Cost price: €115.50
Selling price: €115.50 × 2.8 = €323.40
Per person (6 people): €323.40 ÷ 6 = €54 per person
Seasonal price fluctuations
Ingredient costs aren't static. Smart pricing accounts for:
- Winter premiums: Fresh herbs and vegetables spike in cold months
- Holiday surcharges: Premium ingredients cost more during peak seasons
- Supply disruptions: Build workshops around reliably available products
Review cost calculations quarterly, or immediately after major supplier price changes. A food cost calculator like tools like KitchenNmbrs can automate these updates and prevent margin erosion.
How do you calculate the cost price of a cooking workshop?
Calculate ingredient costs including extras
Add up all ingredients for the number of people, plus 25% extra for demonstration and unforeseen items. Don't forget spices, oil and garnish.
Calculate transportation and preparation
Add up: kilometers × €0.28, parking fees, plus your preparation time × €20-25 per hour. These are real costs you need to pass on.
Determine your selling price with healthy margin
Multiply your total cost price by 2.5 to 3 for a profitable selling price. This gives room for unforeseen costs and profit.
✨ Pro tip
Build a standardized cost calculator spreadsheet for your top 5 workshop formats, updating ingredient prices monthly. This lets you generate accurate quotes in under 10 minutes instead of recalculating from scratch each time.

Frequently asked questions
Do I need to charge VAT on my workshop?
Yes, if your annual turnover exceeds €20,000 you're VAT liable. Cooking workshops fall under 21% VAT, not the 9% restaurant food rate.
What if I'm more expensive than local restaurants?
You should be more expensive - you're providing personalized instruction, not just food. Position workshops as educational experiences with premium, hands-on value that restaurants can't match.
How do I handle last-minute cancellations after buying ingredients?
Implement a 48-hour cancellation policy: free cancellation beyond 48 hours, 50-100% charge within 48 hours. You've already incurred ingredient and prep costs that can't be recovered.
