Most chefs assume fresh seasonal products automatically mean better margins, but the numbers often tell a different story. Frozen alternatives can deliver superior profitability through stable pricing and zero waste. The key lies in calculating true costs beyond the sticker price.
The real costs of fresh vs frozen
Seasonal products aren't just about purchase price. You've got to include every cost to see what's actually cheaper for your bottom line.
💡 Example: Strawberries in March
You're considering strawberries for a dessert:
- Fresh strawberries: €8.50/kg
- Frozen strawberries: €4.20/kg
- Trimming loss fresh: 15% (green hulls, bad ones)
- Shelf life fresh: 3 days
Which do you choose?
Step 1: Calculate the real price per kilo
Fresh products always come with trimming loss. This makes them pricier than what you see on the invoice.
Formula real price = Purchase price / (100% - trimming loss%)
💡 Strawberry calculation:
Fresh strawberries with 15% trimming loss:
€8.50 / 0.85 = €10.00 per kg usable product
Frozen: €4.20 per kg (no trimming loss)
Step 2: Add waste costs
Fresh products spoil faster. Calculate what percentage you're tossing due to spoilage.
- Track for 2 weeks what you throw away
- Divide this by your total purchases
- Add this percentage to your real price
⚠️ Watch out:
Most kitchens underestimate waste. 10% is normal with fresh products, but can spike to 25% with poor inventory management.
Step 3: Compare total costs
Now you can compare actual costs including all losses.
💡 Total strawberry calculation:
Fresh (with 10% waste from spoilage):
- Real price: €10.00/kg
- Plus 10% waste: €10.00 / 0.90 = €11.11/kg
Frozen: €4.20/kg
Difference: €6.91 per kg in favor of frozen
Fresh still wins sometimes
Quality can justify extra costs. This depends on your concept and pricing power.
- Fine dining: guests expect and pay for fresh
- Seasonal menus: fresh ingredients tell your story
- Higher menu price possible: pass on extra costs
- Marketing value: "fresh seasonal products" attracts customers
The practical side: planning and inventory
Frozen gives you flexibility in planning. No stress about products spoiling overnight.
💡 Example: Restaurant week
You're participating in restaurant week with fixed menus:
- 200 covers expected
- With fresh: risk of shortage or surplus
- With frozen: order exact quantities
Frozen eliminates miscalculation risks.
Combination strategy works
After managing kitchen operations for nearly a decade, I've seen successful restaurants strategically combine both.
- Fresh for signature dishes and specials
- Frozen for standard menu items
- Seasonal peaks: buy fresh, use frozen as backup
- Different qualities: fresh for à la carte, frozen for sauces
⚠️ Watch out:
Be transparent with guests. Using frozen where fresh is expected leads to disappointment. Better to offer an honest price-quality ratio.
How do you compare fresh vs frozen for your margin?
Calculate real price per kilo including trimming loss
Divide the purchase price by the yield percentage. With 15% trimming loss: divide by 0.85. This gives you the real price per usable kilo.
Measure your waste percentage for 2 weeks
Track how much fresh product you throw away due to spoilage. Divide this by your total purchases to get the real waste percentage.
Compare total costs and determine your strategy
Add trimming loss and waste to the purchase price. Compare with frozen and choose based on your concept and possible price markup.
✨ Pro tip
Compare fresh vs frozen costs every 3 weeks during peak season - price swings of 40-60% can flip your margin calculations overnight.

Frequently asked questions
Is frozen always cheaper than fresh?
Not always. During peak season, fresh products can actually be cheaper than frozen. But you must factor in trimming loss and waste for a true comparison.
How do I factor waste into my food cost?
Track what you throw away for 2 weeks and divide by total purchases. With 10% waste, divide your real price by 0.90 to get true costs.
Can I use frozen in fine dining?
Yes, but be selective. Use frozen for components like fruit in sauces, but fresh for main ingredients that are central to the dish.
How do I calculate labor costs for prep time differences?
Fresh products typically require 30-40% more prep time than frozen equivalents. Factor in your hourly kitchen wage costs multiplied by the extra prep minutes per portion.
What's the shelf life difference impact on ordering?
Fresh seasonal items usually last 2-5 days versus months for frozen. This means you'll order 6-15 times more frequently, increasing delivery costs and administrative time.
How do I plan purchases with seasonal products?
Use frozen as your base and fresh for specials. This way you always have stock, but can take advantage of good fresh quality in season.
