Sushi restaurants face dramatically different cost structures than traditional kitchens. Raw fish and premium ingredients push food costs higher than most restaurant types. Normal sushi food cost runs 35-45%, varying with fish quality and restaurant positioning.
Why sushi has a higher food cost
Sushi kitchens work with pricier ingredients than most restaurants. The main cost drivers include:
- Premium fish: Tuna, salmon and other sashimi-quality fish costs €25-60 per kilo
- Daily fresh delivery: Fish must be purchased fresh daily
- Cutting loss: Whole fish yields only 45-60% usable meat (head, bones, skin waste)
- Rice and nori: Specialized sushi rice and seaweed cost more than standard rice
⚠️ Heads up:
Too many sushi restaurants miscalculate fish costs. They use whole fish purchase prices but ignore cutting waste. This creates artificially low food cost numbers that don't reflect reality.
Food cost per type of sushi
Different sushi styles carry vastly different margins. Food cost varies by preparation:
- Nigiri with premium fish: 40-50% food cost
- Maki rolls: 25-35% food cost (more rice, less fish)
- Inside-out rolls: 30-40% food cost
- Sashimi: 45-55% food cost (pure fish, no rice)
? Example: Salmon nigiri cost price
Selling price: €3.50 incl. 9% VAT = €3.21 excl. VAT
- Salmon (15g): €0.75
- Sushi rice (20g): €0.15
- Wasabi, ginger: €0.05
Food cost: €0.95 / €3.21 = 29.6%
Calculating actual fish costs
Fish cutting loss creates the biggest costing headache for sushi operations. This is the kind of thing you only learn after closing your first month at a loss - whole fish prices mean nothing without factoring yield.
? Example: Whole salmon purchase
You purchase whole salmon at €18 per kilo
- Whole salmon: 2 kg = €36
- After filleting: 1.1 kg fillet
- Cutting loss: 45%
True fillet cost: €18 / 0.55 = €32.73 per kilo
The formula for real fish costs: Purchase price / (Yield % / 100)
Benchmarks per type of sushi restaurant
- All-you-can-eat sushi: 28-35% (volume model, less premium fish)
- Casual sushi restaurant: 35-42%
- High-end sushi bar: 40-50% (premium fish, omakase menus)
- Sushi delivery: 30-38% (fewer premium cuts, more maki)
? Example: Restaurant food cost mix
Average food cost: 38%
- 60% of sales = maki/rolls (30% food cost)
- 25% of sales = nigiri (45% food cost)
- 15% of sales = sashimi (50% food cost)
Weighted average: (0.6 × 30%) + (0.25 × 45%) + (0.15 × 50%) = 37.75%
How to keep your food cost under control
Sushi demands daily number monitoring. Fish costs too much for sloppy tracking:
- Daily: Track fish usage versus portions sold
- Weekly: Calculate true cost per kilo after cutting waste
- Monthly: Identify your most profitable menu items
Systems like KitchenNmbrs automate these calculations, giving you instant visibility into margin performance.

How do you calculate the correct food cost for sushi?
Calculate actual fish costs after cutting loss
Divide your purchase price by the yield percentage. If you have 45% cutting loss, your yield is 55%. Then divide your purchase price by 0.55 to get the actual kilo price.
Weigh exact portions per type of sushi
Measure how many grams of fish go into each nigiri, maki and sashimi. Multiply this by your actual kilo price to calculate the fish cost per piece.
Add up all ingredients and calculate food cost
Add rice, nori, wasabi, ginger and garnish to the fish costs. Divide the total by your selling price excl. VAT and multiply by 100 to get the food cost percentage.
✨ Pro tip
Track food cost on your top 3 nigiri items weekly - these usually represent 40% of your sushi sales and drive overall margins.
