Managing slow inventory is like playing chess with expiration dates. Many restaurant owners panic and slash prices without calculating their true break-even point. Smart operators know how to move inventory while protecting their bottom line.
Why specials often backfire
You've got 5 kilos of salmon expiring tomorrow. Quick solution: slap a 'salmon special' on the menu for €18 instead of €28. Problem solved? Not even close. You're hemorrhaging money, just doing it on purpose now.
⚠️ Watch out:
A special at cost price isn't a solution. You're bleeding money on labor, energy, and overhead. Plus you're conditioning guests to expect rock-bottom prices.
The profitable special formula
Your goal isn't dumping inventory. It's minimizing loss while staying in the black. That means calculating your absolute floor price—and sticking to it.
? Example:
Salmon purchased at €22/kg. Regular menu price: €28.00
- Salmon fillet per portion (180g): €3.96
- Garnish and sides: €2.50
- Labor and overhead minimum: €3.00
Floor price: €9.46 + VAT = €10.31
Anything above €10.31 still generates profit. A special at €19.50 instead of €28.00 nets you €8.19 per plate. Way better than a €22 write-off.
Your break-even calculation toolkit
Every special needs three critical numbers:
- Raw ingredient cost: What you actually paid
- Variable expenses: Labor, utilities, packaging for this specific dish
- Break-even threshold: Ingredient cost + variables + VAT
Anything above break-even contributes to fixed costs and profit. This is the kind of thing you only learn after closing your first month at a loss—every penny above your floor price still helps.
? Example calculation:
Steak special - meat cost €18/kg, regular price €32
- Meat 220g: €3.96
- Accompaniments: €2.20
- Labor (15 minutes at €20/hour): €5.00
- Utilities and washing: €1.50
Break-even: €12.66 excl. VAT = €13.80 incl. VAT
A €22.00 special still delivers €8.20 profit. Infinitely better than tossing the meat for zero revenue.
Timing and positioning your specials
Timing separates successful specials from margin killers:
- Not too early: Guests start expecting regular discounts
- Not too late: Product quality drops below acceptable standards
- Create urgency: "Today only" or "While supplies last"
⚠️ Watch out:
Skip words like "clearance" or "must go". Use "chef's special" or "seasonal selection". Guests should feel privileged, not like they're buying your leftovers.
Prevention through smart rotation
The smartest special is no special at all. Proper inventory rotation keeps you out of this mess:
- FIFO system: First In, First Out - oldest inventory moves first
- Daily checks: What needs moving within 48 hours?
- Menu integration: Work slow ingredients into popular dishes
? Example rotation strategy:
Excess mushrooms need quick movement:
- Incorporate into bestselling pastas
- Feature mushroom risotto as daily special
- Blend into soups and sauces
- Train servers to upsell mushroom dishes
This moves inventory at full price instead of discounted rates.
Technology for inventory oversight
Manual tracking works but eats time and breeds errors. Tools like KitchenNmbrs streamline the process:
- Monitor ingredient costs in real-time
- Calculate break-even prices automatically

This prevents costly mistakes from poorly calculated specials.

How do you calculate a profitable special price?
Calculate your actual ingredient costs
Add up all ingredients that go into the dish: main product, garnish, sauces, oil, butter. Use the purchase price you actually paid, not the catalog price.
Add variable costs
Include labor time (prep time × hourly wage), energy costs (gas, electricity), and direct costs like packaging. These are costs you always incur per dish.
Calculate minimum selling price
Ingredients + variable costs = break-even excl. VAT. Multiply by 1.09 for the price incl. VAT. Everything above this amount is still profit.
✨ Pro tip
Run a 48-hour inventory scan every Tuesday and Friday to identify items needing quick movement. Price specials at exactly 30% above your calculated break-even to maintain profitability while creating urgency.
Calculate this yourself?
In the KitchenNmbrs app you can do this in just a few clicks. 7 days free, no credit card.
