Festival purchasing demands precise calculations to match expected visitor turnout. Overbuying creates waste while underbuying kills potential sales. Smart calculations help you stock just right without excessive risk.
Calculate your expected sales per day
Start with visitor numbers and figure out how many become your customers. Not every festival-goer will buy from your booth.
💡 Example:
Festival with 5,000 visitors per day, you expect 8% market share:
- Day 1: 5,000 × 8% = 400 customers
- Day 2: 5,000 × 8% = 400 customers
Total: 800 customers over two days
Watch for day-to-day variations. Friday's typically slower than Saturday. Adjust expectations accordingly.
Determine your average transaction value
Calculate what customers spend on average. Festival-goers often order more than usual since it's a special event.
- Main course: €8-12
- Side dish or snack: €3-6
- Drink: €2-4
Average transaction value at festivals typically runs €10-18 per customer.
Calculate your total expected revenue
Multiply customer count by average transaction value for expected revenue.
💡 Example:
800 customers × €14 average transaction = €11,200 total revenue
Distribution across days:
- Day 1 (Friday): €4,480 (40%)
- Day 2 (Saturday): €6,720 (60%)
Plan your purchases based on food cost
Use your target food cost percentage to calculate purchase spending. For festivals, 25-30% food cost works well.
Formula: Maximum purchase = Expected revenue × (Food cost % / 100)
💡 Example:
At €11,200 revenue and 28% food cost:
€11,200 × 0.28 = €3,136 maximum purchase
Divide across ingredient categories
Split your purchase budget by menu categories. Create distribution per main ingredient type.
- Meat/fish: 40-50% of purchases
- Vegetables: 20-25% of purchases
- Bread/sides: 15-20% of purchases
- Sauces/spices: 10-15% of purchases
⚠️ Note:
Plan 10-15% extra purchases as buffer. At festivals you can't quickly reorder if stock runs out.
Calculate portions per ingredient
From years of working in professional kitchens, I've learned that precise portion calculations prevent both shortages and waste during high-volume events.
💡 Example hamburgers:
Expectation: 300 hamburgers over two days
- Hamburger patties: 300 × 150g = 45 kg
- Buns: 300 pieces + 10% buffer = 330 pieces
- Cheese: 300 × 30g = 9 kg
- Lettuce: 300 × 20g = 6 kg
Plan your cooling and storage
Check if you've got enough cooling space for purchases. Festivals often mean limited cooling capacity.
- Calculate cooling space per day
- Plan which products you'll use day 1 vs day 2
- Account for spoilage in warm weather
Create a purchase list per supplier
Divide purchases per supplier to track orders and plan deliveries.
Many operators use systems to track recipes and purchase calculations, especially for complex events like festivals.
How do you plan festival purchases? (step by step)
Calculate expected customers per day
Multiply total number of festival visitors by your expected market share (usually 5-12%). Account for differences between days.
Determine average transaction value
Estimate what a customer orders on average. At festivals this is often between €10-18 per person, depending on your concept and price level.
Calculate maximum purchase
Multiply expected revenue by your desired food cost percentage (25-30%). This is your maximum purchase budget for ingredients.
Plan portions per ingredient
Work out how much of each ingredient you need per dish. Add everything up and add a 10-15% buffer for unexpected crowds.
Check cooling capacity
Check if you have enough cooling space for your total purchases. Plan which products you'll use when to prevent spoilage.
✨ Pro tip
Calculate ingredients needed for your top 3 selling items first, then add supporting dishes. This covers 80% of your volume and prevents over-ordering specialty ingredients that might not move.

Frequently asked questions
How much buffer should I plan for festival purchases?
Plan 10-15% extra purchases as buffer. At festivals you can't quickly reorder, so better to have slightly too much than too little. This prevents lost sales from sold-out items.
How do I calculate my market share at a festival?
Divide the number of food vendors by total visitors and adjust for your location. With 10 food vendors you'd expect about 10% market share, but prime locations can achieve 15%.
What if I have much less sales on day 1 than expected?
Adjust your planning for day 2. Use perishable products first and save shelf-stable items for day 2. Check your prices - maybe they're too high for the audience.
What food cost percentage is realistic for festivals?
25-30% is standard for festivals. You have higher transport costs but also fewer staff than in a restaurant. Always calculate food cost excluding VAT.
How do I prevent food waste in warm weather?
Plan your cooling carefully and use products in order of perishability. Don't prepare too much in advance and keep perishable items out of cooling as briefly as possible.
Should I order all ingredients from one supplier for festivals?
Split between 2-3 reliable suppliers to reduce risk. If one supplier has delivery issues, you're not completely stuck. But don't overcomplicate with too many suppliers either.
