Charity ingredients affect your margins in unexpected ways. Free or discounted items often carry hidden costs like extra processing time and unpredictable quality. You need to calculate the true margin, not just the purchase price savings.
What are charity ingredients?
Charity ingredients come from food waste reduction programs. Examples include:
- Vegetables that don't meet cosmetic standards
- Products near their expiration date
- Supplier overstock
- Seasonal surpluses from farmers
These ingredients typically cost 30-70% less than regular purchases. But the actual cost runs higher than just the purchase price.
Hidden costs of charity ingredients
⚠️ Watch out:
Free ingredients aren't truly free. Hidden costs always impact your margins.
Extra processing time: Charity vegetables need more cleaning, sorting, and prep work. Labor costs add up quickly.
Higher trim loss: Products near expiration or with minor damage create more waste. Your usable yield drops.
Unpredictable quality: Delivery quality varies. Sometimes you'll need to modify recipes on the fly.
Extra storage space: You'll often buy larger quantities than needed immediately.
Calculate the real cost price
💡 Example:
You receive 10 kg carrots for €5 (regular price €15). Seems like €1 savings per kg, but:
- Extra cleaning: 15 minutes at €20/hour = €5
- Trim loss 25% instead of 15% = 1 kg extra waste
- Usable: 7.5 kg instead of 8.5 kg
Actual price: (€5 + €5) / 7.5 kg = €1.33/kg
Compare to regular purchase: €15 / 8.5 kg = €1.76/kg. You save €0.43 per kg, not €1.00. From tracking this across dozens of restaurants, the savings typically shrink by 40-60% once you factor in all costs.
Impact on your dish margin
Your margin depends on the actual cost price, not the purchase price alone.
💡 Example carrot soup:
Selling price: €8.50 incl. VAT = €7.80 excl. VAT
- With charity carrots: €2.10 ingredients total
- With regular carrots: €2.35 ingredients total
Food cost charity: 26.9% vs. regular: 30.1%
The difference shrinks: just 3.2 percentage points. On a soup priced at €7.80 excl. VAT you save €0.25 per portion.
Factor in quality risks
Charity ingredients can be inconsistent. Plan accordingly:
- Buffer ingredients: Keep 10-15% regular purchases as backup
- Flexible recipes: Design dishes that handle quality variations
- Daily specials: Use charity ingredients for rotating menu items
If 1 out of 5 deliveries disappoints and you must buy regular stock anyway, factor this into your average cost calculation.
Administration and registration
⚠️ Watch out:
With charity ingredients, monitor expiration dates closely. FIFO (first in, first out) becomes critical.
Track for each charity ingredient:
- Purchase price and date
- Actual quantity after processing
- Extra labor time
- Trim loss percentage
- Quality assessment
Systems like KitchenNmbrs let you record this data per ingredient and automatically calculate real cost prices.
How do you calculate the margin with charity ingredients? (step by step)
Register all costs
Note not only the purchase price, but also extra labor time for processing. Convert labor to euros per hour (usually €18-25 per hour in the kitchen).
Measure the actual yield
Weigh the product before and after processing. Calculate the trim loss percentage. This is often 10-15% higher with charity ingredients than with regular purchases.
Calculate the real price per kilo
Divide the total costs (purchase + labor) by the usable weight. Use this price in your recipe calculation, not the original purchase price.
Compare with regular purchases
Calculate the same cost price for regular ingredients. The difference is your real savings. Add any quality risks to this.
✨ Pro tip
Track your charity ingredient performance over 6 weeks minimum before committing to regular orders. Quality patterns emerge after this period, giving you realistic cost calculations.

Frequently asked questions
Do I need to register charity ingredients differently for HACCP?
No, the same rules apply. Pay extra attention to expiration dates and delivery temperatures though. Charity products often have shorter remaining shelf life.
Can I use charity ingredients for all dishes?
Not recommended. For signature dishes or items requiring consistency, stick with regular purchases. Charity ingredients work better for daily specials and seasonal offerings.
How do I factor in the risk of poor deliveries?
If 1 out of 5 deliveries fails, add 20% of regular purchase price to your average charity cost. This covers times you'll need to buy regular stock as backup.
Is the margin always better with charity ingredients?
Usually, but not always. With vegetables having high trim loss or items requiring extensive labor, differences can be minimal. Always calculate the true cost price first.
Can I combine charity ingredients with regular purchases?
Yes, that's often smart strategy. Use charity ingredients as your base and keep 10-15% regular purchases for backup when quality drops or quantities fall short.
How do I handle charity ingredients with varying quality levels?
Create quality grades (A, B, C) and assign different uses for each. Grade A for premium dishes, Grade B for soups and sauces, Grade C for staff meals or composting.
What's the minimum order quantity impact on charity ingredient costs?
Charity suppliers often require large minimum orders. Factor storage costs and potential spoilage into your calculations. Sometimes smaller regular orders cost less overall than large charity purchases.
