Buying seasonal produce fresh or pre-cut can make a difference of 20-40% in your food cost. Most kitchens make this choice by instinct, overlooking the hidden expenses of labor and waste. Here's your step-by-step method to determine which option delivers real financial value.
The real costs of buying fresh
Fresh always looks cheaper on paper. You're paying less per kilo, sure. But there are hidden expenses that can seriously inflate your food costs.
- Labor time: Cleaning, cutting, portioning
- Trim loss: Peels, cores, bad pieces
- Waste: Spoiled products from longer storage
- Storage space: More cooling needed for fresh product
💡 Example: Carrots in season
Fresh bunch carrots vs. pre-cut carrot chunks:
- Fresh: €1.20/kg
- Pre-cut: €2.80/kg
- Difference: €1.60/kg (57% more expensive)
But is that difference realistic after accounting for all expenses?
Calculate the true cost price of fresh
You need to factor in every expense for an honest comparison. Here's your formula:
Real cost price fresh = (Purchase price + Labor time + Waste) / Net yield
💡 Example: Complete carrot calculation
10 kg fresh carrots for €12.00:
- Purchase price: €12.00
- Labor time: 30 min × €20/hour = €10.00
- Trim loss: 15% (peels, tips)
- Waste: 5% (rot, damaged)
Net yield: 10kg × 80% = 8kg usable
Real cost price: (€12 + €10) / 8kg = €2.75/kg
Compare with pre-cut
Pre-cut products carry hidden costs too, but they're typically lower:
- No labor time for processing
- Less waste from shorter storage
- Higher purchase price per kilo
- Shorter shelf life can create more waste
💡 Example: Pre-cut carrots
8kg pre-cut carrot chunks for €22.40:
- Purchase price: €22.40 (€2.80/kg)
- Labor time: 0 minutes = €0
- Waste: 2% (shorter storage)
Net yield: 8kg × 98% = 7.84kg usable
Real cost price: €22.40 / 7.84kg = €2.86/kg
Fresh makes financial sense when
Buying fresh pays off particularly in these situations:
- Large volumes: Labor time per kilo drops
- Affordable labor: Interns or quiet periods
- Minimal trim loss: Products you use completely
- Extended shelf life: Potatoes, onions, carrots
⚠️ Note:
Calculate labor at your actual hourly rate, including payroll taxes. That's often €18-22 per hour, not your employee's net wage.
Factor in seasonality
With seasonal produce, price gaps shift throughout the year. I've seen restaurants make a mistake that costs them EUR 200-400 per month by not recalculating these numbers seasonally. Run calculations for different periods:
- Peak season: Fresh much cheaper, pre-cut price stays stable
- Off-season: Fresh more expensive, difference shrinks
- Import period: Fresh quality worse, more waste
💡 Example: Asparagus through the season
Dutch asparagus in May vs. imported in March:
- May (season): €6/kg fresh, minimal trim loss
- March (import): €12/kg fresh, 25% trim loss from transport
- Pre-cut: €18/kg year-round
In May: fresh wins. In March: pre-cut can be cheaper.
Practical decision-making guide
Use these quick-check guidelines:
- Price difference under 50%: Usually choose pre-cut
- Price difference above 100%: Fresh is often better value
- Between 50-100%: Calculate it with the full formula
Food cost calculators can save these calculations and automatically update them as supplier prices change. That way you'll know immediately when it's time to switch between fresh and pre-cut.
How do you calculate the real cost price? (step by step)
Gather all costs for fresh product
Note the purchase price per kilo, time needed for processing (in minutes), and estimate the trim loss percentage. Also count waste from spoilage.
Calculate labor time in euros
Multiply the processing time by your hourly wage (including payroll taxes). For most kitchens, this is €18-22 per hour.
Calculate the real cost price
Add purchase price and labor time, divide by net yield (100% minus trim loss and waste). Compare this with the pre-cut price.
✨ Pro tip
Track your actual prep times for 2 weeks before making this calculation. Most kitchens underestimate processing time by 30-40%, which skews the numbers toward fresh produce when pre-cut might actually save money.

Frequently asked questions
Should I count the time for washing up too?
Yes, all extra labor belongs in the cost price. Think about washing cutting boards, cleaning knives, and disposing of waste. Budget roughly 5-10 minutes extra per processing round.
How do I know the trim loss percentage of a product?
Measure it a few times: weigh the product before and after processing. Average trim loss is 10-15% for root vegetables, 20-30% for leafy greens, and 40-50% for whole fish.
What if my chef can cut very quickly?
Then buying fresh becomes more cost-effective. Calculate with your team's actual cutting time, not an average. Experienced cooks can really bring down labor time.
