Crowdfunding and community supported agriculture (CSA) make ingredients accessible at unique price structures. You often pay upfront for a season or project, which makes calculating the actual purchase price per kilo tricky. In this article, you'll learn how to convert these alternative purchasing methods into usable cost prices for your recipes.
What are crowdfunding and CSA ingredients?
Crowdfunding ingredients are purchased through platforms where producers raise money upfront for their harvest. For example, you pay €200 for a share of olive oil production and receive bottles later.
Community Supported Agriculture (CSA) works with subscriptions. You pay €300 for a season of vegetables and receive a box with varying contents each week.
- You don't know in advance exactly what quantities you'll receive
- Quality can vary per delivery
- You often pay months before delivery begins
- The price per kilo isn't directly visible
Calculate your actual purchase price
For your cost price calculation, you need a clear price per kilo or per unit. With crowdfunding and CSA, you'll need to calculate this yourself.
💡 Example CSA vegetable box:
You pay €300 for 20 weeks of vegetables. After 10 weeks you've received:
- Carrots: 8 kg total
- Potatoes: 12 kg total
- Lettuce: 15 heads total
You've paid €150 for these 10 weeks. Carrot price: €150 ÷ 40 kg total = €3.75/kg
Step 1: Keep a delivery log
Record each delivery: date, product, quantity, quality. Without this, you can't calculate a reliable cost price.
Step 2: Calculate monthly
Update your cost price each month. Divide the amount paid by the quantity received so far.
⚠️ Note:
Your cost price changes with each delivery. Start conservatively with a higher estimate and adjust downward if you receive more than expected.
Account for waste and loss
CSA products are often less standardized than supermarket vegetables. Trimming loss can be higher.
💡 Example waste calculation:
You receive 5 kg of carrots from your CSA box. After peeling and trimming, you have 4 kg left.
- Trimming loss: 20% (1 kg waste from 5 kg)
- CSA price: €3.75/kg
- Actual price: €3.75 ÷ 0.80 = €4.69/kg usable product
Measure this a few times and use the average for your cost price calculation. CSA vegetables typically have 5-10% more trimming loss than supermarket vegetables.
Include upfront payment in cost price
You pay months in advance, but use the ingredients later. This costs you money (opportunity cost).
Simple method: Add 2-3% to your calculated purchase price for each month you pay upfront. At 6 months upfront, your €4.00/kg becomes €4.48/kg.
Why this matters: The money you pay upfront can't be used for other purchases or investments. Those missed opportunities cost you money.
Compare with regular suppliers
CSA and crowdfunding aren't always cheaper, despite the direct connection with the producer.
💡 Example cost comparison:
Comparing organic carrots:
- CSA: €4.69/kg (including trimming loss and upfront payment)
- Wholesale organic: €3.20/kg
- Local farmer direct: €2.80/kg
CSA is €1.49/kg more expensive, but offers story value for guests.
Calculate whether the premium justifies the marketing value. Guests sometimes pay more for a story about local farmers and sustainability.
Administration and taxes
Keep all payment receipts and delivery slips. CSA payments are ordinary business expenses, just like other ingredients.
For bookkeeping: First book the upfront payment as inventory/prepaid costs. Only book as a purchase when you actually receive and use the ingredients.
A system like KitchenNmbrs helps you track your actual cost price, even with varying deliveries like CSA boxes.
How do you calculate the purchase price of crowdfunding/CSA ingredients?
Start a delivery log
Record each delivery: date, product, quantity, and quality. Without this log, you can't calculate a reliable cost price. Update it immediately with each delivery.
Calculate your running cost price
Divide the total amount paid by the quantity received so far. Update this calculation each month to have a current cost price for your recipes.
Measure and calculate trimming loss
Weigh your ingredients before and after processing. CSA products often have 5-10% more trimming loss. Divide your cost price by the yield (100% - trimming loss%) for the actual price.
Add upfront payment costs
For each month you pay upfront, add 2-3% to your cost price. This compensates for the fact that your money is tied up and can't be used for other purposes.
Compare with regular suppliers
Calculate whether the premium of CSA/crowdfunding justifies the marketing value. Guests sometimes pay more for a story about local production and sustainability.
✨ Pro tip
Start your CSA season with a cost price estimate 20% higher than your calculation. Adjust downward as you receive more than expected—this prevents you from undercharging for your dishes.

Frequently asked questions
Can I deduct CSA costs as business expenses?
Yes, CSA payments are ordinary business expenses. Book the upfront payment first as inventory and only as a purchase when you actually receive and use the ingredients in your kitchen.
What if I receive less than expected from my CSA subscription?
Start conservatively with a higher cost price estimate. If you receive more than expected, adjust the cost price downward. This prevents you from undercharging for your dishes.
How do I handle varying quality in CSA deliveries?
Note the quality in your log and adjust your trimming loss percentage. With lower quality, you calculate more waste, which increases your actual cost price per usable kilo.
Is crowdfunding of ingredients always cheaper?
No, often not. After accounting for trimming loss, upfront payment costs, and administration time, crowdfunding ingredients are sometimes more expensive than regular suppliers. The added value lies in story and marketing.
How often should I update my CSA cost price?
Update your cost price each month or after each major delivery. Your cost price changes as you receive more, so regular updates give you a more realistic picture for your recipe calculations.
