Working with one farmer sounds romantic, but calculating your margins becomes more complex. You have fewer suppliers to compare prices with and seasonal fluctuations hit you harder. Learn how to calculate your food cost and monitor profitability with a farm-to-table concept.
Why one farmer requires different margin calculations
At a traditional restaurant you compare prices from multiple suppliers. With one farmer you work with fixed prices and seasonal availability. This affects your cost price calculation in three ways:
- Prices are often higher than wholesale (but quality too)
- Availability varies by season
- No alternative if prices rise
? Example farmer prices:
Compare these prices for organic vegetables:
- Farmer direct: €8.50/kg organic carrot
- Wholesale organic: €6.20/kg
- Difference: 37% more expensive
You need to compensate this with higher menu prices or lower food cost elsewhere.
Calculate your actual purchasing costs
With one farmer you calculate differently than with wholesale. You need to account for:
Seasonal fluctuations: The same carrot costs €6/kg in March, €9/kg in July. Calculate a yearly average for stable menu pricing.
Minimum orders: Many farmers work with minimum amounts or fixed crates. Convert this to price per kilo.
? Example seasonal average:
Organic zucchini from your farmer:
- March-May: €4.50/kg
- June-August: €2.80/kg (season)
- September-November: €5.20/kg
- December-February: €7.50/kg
Yearly average: €5.00/kg - use this in your cost price calculation.
Food cost formula for farm-to-table
The basic formula stays the same, but watch these points:
Food cost % = (Ingredient costs / Sales price excl. VAT) × 100
At farm-to-table concepts you often see higher food cost percentages (35-42%) because:
- Ingredients are more expensive than wholesale
- Guests are willing to pay more for the story
- Less waste due to fresh products
⚠️ Watch out:
A food cost of 40% can be profitable if your story justifies a premium price. Don't blindly compare with traditional restaurants that achieve 30%.
Compensate for higher purchasing costs
After managing kitchen operations for nearly a decade, I've learned three strategies to stay profitable with more expensive purchases:
1. Higher menu price: Guests pay 15-25% more for farm-to-table. Communicate this story clearly.
2. Lower labor cost: Simpler dishes that let the product speak for itself. Less processing costs.
3. Less waste: Process fresh products immediately. Plan menu around farmer deliveries.
? Example compensation strategy:
Traditional restaurant vs. farm-to-table:
- Traditional: €8 ingredients, €28 menu price → 31% food cost
- Farm concept: €12 ingredients, €36 menu price → 36% food cost
- Difference: €4 more ingredient, €8 more revenue
Net: €4 more margin per dish despite higher food cost.
Seasonal menu
With one farmer you change your menu more often. This requires different cost price calculation:
Fixed dishes: Calculate with yearly average prices for stable menu.
Seasonal specials: Calculate with current seasonal price. Can give lower food cost in season.
Cover shortages: Always have 2-3 dishes that work with alternative ingredients.
Administration and control
With one farmer control is organized differently:
- Weekly delivery schedule instead of daily orders
- Quality control more important (no alternative)
- Inventory planning crucial (no quick reorder)
A food cost calculator like KitchenNmbrs helps you track seasonal prices and automatically adjust your food cost calculations.

How do you calculate margins with one farmer? (step by step)
Collect yearly average prices from your farmer
Ask your farmer for a price overview per season. Calculate the average of 12 months for each main ingredient. This gives you stable cost prices for menu planning.
Calculate cost price per dish including premium surcharge
Add up all ingredient costs at yearly average prices. Add 10-15% for seasonal peaks and unexpected price increases. This is your actual cost price.
Determine your maximum food cost percentage
For farm-to-table concepts, 35-42% food cost is acceptable if your story justifies a premium price. Calculate your minimum sales price: cost price / (food cost% / 100).
Test your pricing in the market
Start with a test menu for 4 weeks. Measure whether guests accept the premium price. Adjust food cost or prices based on sales figures and feedback.
✨ Pro tip
Negotiate a 90-day price lock with your farmer during peak harvest months. This gives you cost stability for menu planning while letting you capture the lowest seasonal prices for your core ingredients.
