Most sushi restaurants estimate their roll costs and bleed money daily. While competitors guess at their margins, smart operators calculate every grain of rice and gram of salmon. Here's exactly how to price your California rolls, sake maki, and inside-out rolls down to the cent.
Why sushi cost price matters so much
Sushi appears straightforward: rice, fish, nori. But profitability lives in the details. Every gram of salmon, each spoonful of rice, and every avocado slice adds up. One extra gram of salmon per roll? That'll cost you hundreds of euros yearly.
💡 Example: California roll (8 pieces)
Ingredients per roll:
- Rice: 120g = €0.18
- Nori: 1 sheet = €0.15
- Surimi: 40g = €0.80
- Avocado: 30g = €0.45
- Cucumber: 20g = €0.08
- Mayonnaise: 5g = €0.03
- Sesame seeds: 2g = €0.06
Total cost price: €1.75 per roll
Gather all ingredient prices
Build a complete list of every ingredient in your sushi rolls. Don't skip the small stuff you typically overlook:
- Foundation: sushi rice, nori sheets, wasabi, ginger
- Proteins: salmon, tuna, surimi, shrimp
- Fresh elements: avocado, cucumber, carrot, bell pepper
- Flavor makers: soy sauce, mayo, sriracha, teriyaki
- Finishing touches: sesame seeds, tobiko, tempura flakes
Record the purchase price per kilogram for each ingredient. Pull your invoices from last month for current pricing data.
⚠️ Note:
Fish gets sold per kilo but used per 100 grams. Always convert to grams: €24/kg salmon = €0.024 per gram.
Measure exact quantities per roll
Each sushi roll follows a standard recipe. Measure this once accurately and use it as your calculation foundation.
Standard quantities per roll (8 pieces):
- Rice: 100-140 grams (varies by roll style)
- Nori: 1 full sheet or 0.5 sheet
- Fish: 30-50 grams (salmon, tuna)
- Vegetables: 20-40 grams per ingredient
- Sauce: 3-8 grams per type
💡 Example: Salmon avocado roll
Ingredients per roll:
- Sushi rice: 130g × €0.0015/g = €0.20
- Nori: 1 sheet × €0.15 = €0.15
- Salmon: 45g × €0.032/g = €1.44
- Avocado: 35g × €0.015/g = €0.53
- Sesame seeds: 3g × €0.03/g = €0.09
Total cost price: €2.41 per roll
Account for cutting loss on fish
Fish always involves waste. You purchase whole salmon but only the prime cuts make sushi-grade portions. This cutting loss inflates your actual fish costs beyond the purchase price.
Typical cutting loss for sushi fish:
- Whole salmon: 35-45% loss (skin, bones, inferior cuts)
- Salmon fillet: 15-25% loss (trimming, skin removal)
- Tuna: 20-30% loss
- Surimi: Zero loss (pre-processed)
Calculate your real fish price:
Actual price = Purchase price ÷ (100% - Cutting loss%)
💡 Example: Salmon cutting loss
You buy salmon fillet for €28/kg:
- Cutting loss: 20%
- Usable portion: 80%
- Real price: €28 ÷ 0.80 = €35/kg
- Per gram: €0.035
So cutting loss adds €7 per kilo to your costs.
Add up all costs
Build a detailed breakdown for each roll showing every ingredient and its cost. Include everything, even the wasabi and ginger served alongside each order.
Formula per roll:
Cost price = (Rice + Nori + Fish + Vegetables + Sauces + Garnish)
⚠️ Note:
Treat wasabi and ginger as fixed costs per order, not per roll. Split this across your average rolls per order.
Calculate your food cost percentage
Now you can determine if your roll generates profit. Food cost represents the percentage of your selling price consumed by ingredients.
Formula:
Food cost % = (Cost price ÷ Selling price excl. VAT) × 100
💡 Example: Food cost calculation
California roll:
- Cost price: €1.75
- Selling price: €8.50 incl. VAT
- Selling price excl. VAT: €8.50 ÷ 1.09 = €7.80
- Food cost: (€1.75 ÷ €7.80) × 100 = 22.4%
That's a solid margin for sushi operations.
Target food costs for sushi typically range between 20-30%. Fish costs more, but sushi commands premium pricing compared to standard dishes. From tracking this across dozens of restaurants, successful operators rarely exceed 32% on their signature rolls.
Keep prices up-to-date
Fish prices swing dramatically. Salmon can jump 20% in a single month. Review your purchase prices monthly minimum and update calculations immediately.
Digital systems help automate this process by storing your sushi recipes and recalculating costs whenever ingredient prices shift.
How do you calculate the cost price of a sushi roll? (step by step)
Make an ingredients list
Note all ingredients that go into the roll: rice, nori, fish, vegetables, sauces and garnish. Look up the purchase price per kilogram of each ingredient.
Measure exact quantities
Weigh how many grams of each ingredient you use per roll. A standard roll has 100-140g rice, 1 nori sheet and 30-50g fish.
Account for cutting loss
Fish has 20-45% cutting loss. Divide your purchase price by the usable percentage to get the actual price.
Calculate total cost price
Multiply each ingredient (grams × price per gram) and add everything together. This is your cost price per roll.
Check your food cost percentage
Divide your cost price by your selling price (excl. VAT) and multiply by 100. A healthy food cost for sushi is 20-30%.
✨ Pro tip
Weigh your salmon portions for 50 consecutive rolls this week. Most sushi chefs unknowingly over-portion by 8-12 grams, which costs €2,400+ annually on a single popular roll.

Frequently asked questions
Should I include wasabi and ginger in the cost price?
Yes, but split this across your average rolls per order. If you provide €0.20 worth of wasabi and ginger per order and typically sell 3 rolls per order, allocate €0.07 per roll.
How often should I update my sushi cost prices?
Monthly at minimum, since fish prices fluctuate wildly. When your supplier announces major price increases, adjust immediately or you'll lose money on every roll. Some operators check weekly during volatile periods.
What's a normal food cost for sushi?
Between 20-30% is standard. Fish costs more but sushi commands premium pricing. California rolls typically run 22-25%, while premium rolls loaded with salmon can hit 28-32%.
How do I calculate inside-out rolls that use more rice?
Inside-out rolls require 130-150g rice versus 100-120g for standard rolls. Measure this precisely once and use it as your standard for all inside-out calculations. The extra rice typically adds €0.05-0.08 per roll.
