Ever wondered if your bestselling dish is actually making you money? Most restaurant owners see frequent orders and assume success, but popularity doesn't equal profitability. Your most ordered dish might be quietly draining your profits every single day.
Why popular dishes can lose money
A dish that flies out of the kitchen feels like pure gold. But high order volume tells you nothing about profit margins. Popular dishes actually face higher risk of becoming silent money drains.
💡 Example:
You sell 150 pasta carbonaras per week for €16.50 (incl. 9% VAT):
- Selling price excl. VAT: €15.14
- Ingredient costs: €6.20
- Food cost: 41%
At 150 portions per week you lose €234 in profit due to excessive food cost.
The hidden causes of losses
Five sneaky reasons why your crowd-pleasers can secretly bleed money:
- Generous portions: Your chef adds extra because customers love it
- Outdated prices: Suppliers increased costs, you didn't adjust
- Forgotten costs: Garnishes, sauces and oils get overlooked
- Waste miscalculation: You use purchase price, not true cost price
- Zero monitoring: Nobody verifies if calculations still work
⚠️ Watch out:
Higher popularity means bigger losses if food costs run wild. A dish ordered 5 times weekly with 5% excess food cost hurts less than your bestseller with just 2% overage.
How generous portions devour your profit
Chefs often add extra to popular dishes. Pride kicks in, habits form, and guests smile wider. But that additional 20 grams of protein costs real money.
💡 Steak example:
Planned: 200 grams entrecote at €28/kg = €5.60 per portion
Actual: 250 grams entrecote = €7.00 per portion
- Extra cost per portion: €1.40
- At 80 portions per week: €5,824 per year
Outdated prices: the silent profit killer
Suppliers bump their prices regularly. Sometimes you get notice, sometimes you don't. You avoid adjusting menu prices because the dish performs so well. Meanwhile, your margins vanish into thin air.
Most restaurant owners review cost prices once yearly. With high-volume dishes, that's often months too late - a mistake that costs the average restaurant EUR 200-400 per month.
💡 Salmon example:
January: salmon €24/kg, portion €4.80
July: salmon €29/kg, portion €5.80
- Extra cost: €1.00 per portion
- At 60 portions per week: €3,120 per year loss
The forgotten costs that pile up
Small ingredients slip through the cracks during cost calculations. Olive oil drizzles, plate butter, parsley garnish. Each portion seems insignificant. Multiply by thousands yearly and you'll feel the sting.
- Olive oil: €0.15 per portion
- Butter on plate: €0.08 per portion
- Fresh herbs: €0.12 per portion
- Lemon garnish: €0.05 per portion
That's €0.40 per portion total. With a crowd favorite ordered 100 times weekly: €2,080 yearly in 'invisible' costs.
Why nobody catches this
Popular loss-makers hide behind impressive volume numbers. You see the revenue rolling in, watch the kitchen buzz, but miss that each plate costs instead of pays.
Plus, entrepreneurs fear raising prices on popular items. They worry about losing customers. But you're already losing money on every single portion.
⚠️ Watch out:
A popular dish with 40% food cost destroys more profit than a rarely-ordered dish with 50% food cost. Volume amplifies the damage.
How to prevent this
The fix is straightforward: monitor food costs on your top sellers monthly, not annually. Adjust prices when needed.
Focus on your 5 best-selling dishes first. Get those profitable and you'll solve 80% of potential problems. Tools like KitchenNmbrs can automate this tracking, alerting you immediately when food costs spike too high.
How do you check if your popular dish is losing money?
Calculate the actual cost price
Add up all ingredients: main product, garnish, sauces, oil, butter, herbs. Don't forget anything. Not even the slice of lemon or sprig of parsley.
Divide by your selling price excl. VAT
Take your menu price, subtract 9% VAT. Then divide your cost price by this price and multiply by 100. That's your food cost percentage.
Check if it stays under 35%
Above 35% food cost? Then this dish is probably losing money. The more popular the dish, the more money you lose per month.
✨ Pro tip
Track food costs on your 3 bestsellers every 30 days. If those stay profitable, you'll prevent most potential losses before they compound.
Calculate this yourself?

Frequently asked questions
What if my most popular dish has 40% food cost?
You're bleeding money with every order. Raise prices by €2-3 or trim portion sizes. A slightly less popular dish that actually profits beats a bestseller that loses money.
How often should I check my food cost?
Monthly for your top 5 sellers. Suppliers adjust prices regularly, and with high-volume dishes, every delayed day costs real money.
Can't I just estimate whether a dish is profitable?
Estimates usually miss the mark badly. You'll underestimate costs on popular dishes because small ingredients get forgotten. Calculate with exact current prices instead.
How do I know if my chef gives oversized portions?
Weigh portions randomly or track yield - how many servings do you actually get from 1kg of product? If it doesn't match your calculations, portions are too generous.
