Here's what nobody tells you about soup dishes: I spent three months thinking my ramen was profitable at €12 until I actually weighed every garnish and timed every broth batch. Ramen and pho seem straightforward, but they're cost calculation nightmares with dozens of small ingredients that add up fast. The real challenge isn't the obvious stuff like noodles—it's tracking every gram of miso paste and accounting for 12-hour broth cooking times.
All components of a soup dish
A ramen or pho consists of multiple parts that each have their own costs. Many kitchens forget the small ingredients, which causes the cost price to come out too low.
💡 Example ramen breakdown:
- Broth (500ml): €2.40
- Ramen noodles (120g): €0.85
- Chashu pork belly (80g): €2.20
- Ajitsuke egg (half): €0.45
- Nori, spring onion, bamboo: €0.60
- Miso paste, oil, spices: €0.35
Total cost price: €6.85
Calculating broth cost price
The broth is often the most expensive part, but also the trickiest to calculate. You need to account for bone trim loss and the long cooking time.
- Bones and meat: calculate with actual weight after cooking (significant loss)
- Vegetables and aromatics: onions, carrots, ginger, spices
- Energy costs: 8-12 hours of cooking uses energy
- Yield: how many liters of broth do you get from your ingredients?
💡 Broth cost price calculation:
For 10 liters of ramen broth:
- Pork bones (5kg): €15.00
- Chicken bones (2kg): €4.00
- Vegetables and spices: €8.00
- Energy (12h cooking): €3.50
Total €30.50 for 10 liters = €3.05 per liter
Per serving (500ml): €1.53
Noodles and base ingredients
The noodles and base ingredients are easier to calculate because they're fixed quantities per serving.
- Fresh ramen noodles: usually 100-130g per serving
- Rice noodles (pho): usually 80-120g dry weight
- Always cook them before calculating the cost price - noodles expand
⚠️ Note:
Always calculate with cooked weight for noodles. 100g dry rice noodles becomes approximately 300g cooked. So your cost price per gram drops by a factor of 3.
Meat and protein calculation
The meat is often the most expensive part after the broth. Prepared meat always has trim loss and shrinkage from cooking—that's the kind of thing you only learn after closing your first month at a loss.
- Chashu (braised pork belly): 20-30% weight loss from braising
- Pho beef: calculate with raw weight, but portion when cooked
- Chicken: whole chicken has 40% trim loss (bones, skin)
Garnish and finishing touches
Small ingredients add up quickly. Many kitchens underestimate these costs because each ingredient only costs a few cents per serving.
💡 Pho garnish costs:
- Fresh herbs (basil, cilantro): €0.35
- Bean sprouts (50g): €0.15
- Lime (quarter): €0.25
- Chili pepper: €0.10
- Hoisin and sriracha sauce: €0.20
Garnish total: €1.05
Putting together the total cost price
Add up all components for your total cost price per serving. Don't forget the small things like sesame oil, garlic and ginger.
- Make a checklist of all ingredients that go on the plate
- Weigh everything the way you use it in the kitchen
- Update regularly your purchase prices - especially fresh herbs fluctuate
Food cost percentage for soups
Soup dishes often have a slightly higher food cost than other dishes due to the labor-intensive broth and the many ingredients.
- Ramen restaurants: food cost usually 32-38%
- Pho restaurants: food cost usually 28-35%
- Casual Asian soups: food cost usually 25-32%
⚠️ Note:
A slightly higher food cost can be okay if you need fewer staff for service. Many ramen bars operate with counter service and fewer staff.
How do you calculate the cost price of a soup dish? (step by step)
Calculate your broth cost price per liter
Add up all ingredients for one batch of broth: bones, meat, vegetables, spices and energy costs. Divide this by the number of liters you get. Calculate 500ml broth per soup serving.
Weigh and price all fixed components
Weigh the noodles, meat and all garnish the way you serve it. For meat, calculate with the weight after preparation (cooking loss). Also include all small ingredients: oils, sauces, spices.
Add everything up and calculate your food cost percentage
Broth + noodles + meat + garnish = total cost price. Divide this by your selling price excluding VAT and multiply by 100 for your food cost percentage. Aim for maximum 35% for soup dishes.
✨ Pro tip
Batch your tare in 25-serving portions and freeze them in ice cube trays. Each cube costs exactly €0.52 and thaws perfectly in hot broth—no more guessing portion sizes or wasting expensive miso paste.

Frequently asked questions
Should I include the energy costs of cooking broth?
Yes, definitely for long cooking times of 8+ hours. Calculate approximately €0.30-0.40 per hour for a large pan on gas. At 12 hours of cooking that's €3.50-4.80 in additional costs per batch.
How do I calculate trim loss for broth meat?
Weigh the meat before and after cooking. Bones and cartilage don't count in your final weight. Pork bones usually yield 30-40% usable meat, chicken bones 25-35%.
Can I estimate the cost of garnish?
Better not to. Fresh herbs, lime and sauces quickly cost €1-1.50 per serving. That's 15-20% of your total cost price. Weigh it properly once and use those figures.
Why is my food cost higher than other dishes?
Soups have many components and labor-intensive broth. A food cost of 32-38% is normal for authentic ramen or pho. Compensate this with efficient service and higher turnover.
How often should I update my broth cost price?
Check your purchase prices for bones and vegetables monthly. These fluctuate seasonally. If your supplier raises prices by more than 10%, recalculate your cost price immediately.
Should I cost out the tare separately from the broth?
Absolutely. The tare (miso, shoyu, or shio base) can add €0.40-0.80 per bowl depending on concentration. Many shops underestimate this because it's such a small portion, but premium miso paste costs €12-15 per kilo.
