Market-price products like fresh fish or seasonal vegetables create profit opportunities, but many restaurants lose money on them due to poor calculations. Your purchase prices fluctuate daily, making pricing decisions complex. The key is understanding how to calculate profitable ranges rather than fixed costs.
Why market-price products are interesting
Market-price products carry higher perceived value with guests. They'll pay more for "fresh sea bass from today" than for a standard dish. However, your purchase prices fluctuate, so you must be more flexible with your pricing.
💡 Example:
You buy fresh sea bass for €18/kg (Monday) or €24/kg (Friday).
- Portion: 200 grams fillet (300g whole = €5.40-€7.20)
- Side dishes: €3.50
- Total ingredients: €8.90-€10.70
Selling price: €32-€38 depending on purchase price
The basic calculation for market prices
For market-price products, you don't calculate one fixed cost price, but a range. You need minimum and maximum scenarios to determine whether the dish remains profitable.
Formula minimum selling price:
Highest ingredient costs ÷ Desired food cost % = Minimum selling price excl. VAT
💡 Example calculation:
Highest ingredient costs: €10.70 (expensive day)
Desired food cost: 30%
Minimum selling price: €10.70 ÷ 0.30 = €35.67 excl. VAT
Menu: €35.67 × 1.09 = €38.88 incl. VAT
Assessing risks
Market-price products carry more risks than standard dishes. You need to factor these into your calculation:
- Waste risk: Fresh products have shorter shelf life
- Price fluctuations: Purchase prices can rise quickly
- Availability: Product may be sold out at supplier
- Demand risk: Guests might order less on expensive days
⚠️ Note:
Always calculate with 10-15% extra waste for market-price products. Fresh fish or meat deteriorates faster than frozen products.
Estimating sales potential
A market-price dish must be ordered frequently enough to be profitable. Calculate the break-even point per day based on real restaurant P&L data showing that dishes selling fewer than 2 portions daily typically lose money due to prep costs.
Break-even calculation:
Fixed costs per dish (prep, waste) ÷ Margin per portion = Minimum number of portions per day
💡 Example break-even:
- Daily prep time: 30 min × €25/hour = €12.50
- Waste (average): €8.00
- Fixed costs per day: €20.50
- Margin per portion: €25.00 (sales) - €9.50 (average cost) = €15.50
Break-even: €20.50 ÷ €15.50 = 1.3 → minimum 2 portions per day
Factoring in seasonal patterns
Market-price products often have seasonal patterns. Fish costs more in winter, asparagus is only available in season. Create a yearly plan to see if the dish stays profitable year-round.
- High season: Higher prices, more guest demand
- Mid-season: Average prices, stable demand
- Low season: Lower prices, possibly less demand
Practical tips for market prices
Successful market-price dishes require a different approach than standard menu items:
- Flexible menu: Use chalkboards or daily specials
- Adjust portion size: Serve smaller portions when purchase prices are high
- Have an alternative ready: If market price is sold out at supplier
- Train your team: Staff must be able to sell the dish
💡 Example flexible pricing:
Sea bass market price on menu:
- Monday-Tuesday: €32 (cheap purchase)
- Wednesday-Thursday: €35 (average purchase)
- Friday-Saturday: €38 (expensive purchase)
Food cost stays stable around 28-30%
How do you calculate whether a market-price dish is profitable?
Gather price data from your supplier
Ask your supplier for the price range of the product over the last 3 months. Note the lowest, average, and highest price per kilo. Also factor in trimming loss to determine the actual kilo price.
Calculate your cost price range
Create three scenarios: cheap day, average day, and expensive day. For each scenario, calculate the total ingredient costs per portion, including side dishes and garnish. Add 10-15% waste on top.
Determine your selling prices per scenario
Divide your highest ingredient costs by your desired food cost percentage (usually 30%). This gives you the minimum selling price. Create a price ladder for different purchase prices so you can respond flexibly.
Test demand with your guests
Start with a trial period of 2 weeks. Track how many portions you sell at each price level. If you sell at least 2-3 portions per day, the dish is usually profitable enough.
✨ Pro tip
Test your market-price calculations for 14 days with purchase prices varying by at least 20% to ensure profitability across the full range. Track actual food costs daily during this period.

Frequently asked questions
How often should I adjust my market prices?
Check your purchase prices with your supplier at least 2x per week. If the price rises or falls by more than 15%, adjust your menu price to protect your margin.
What if guests complain about changing prices?
Explain that market prices depend on freshness and availability. Guests usually understand this if you communicate it well. Put on your menu 'market price, ask your server'.
How do I prevent too much waste with market prices?
Buy conservatively, especially at first. Better to sell out than have too much waste. Track how much you sell on average and adjust your purchases accordingly.
