Daily specials boost revenue but wreak havoc on food cost management. New dishes each week means fresh calculations, and before you know it you're hemorrhaging money from underestimated costs. Here's a practical system to track food costs even with constantly changing specials.
Why daily specials make food cost control so difficult
Fixed menus? Calculate once and you're done. Daily specials demand weekly recalculation:
- Look up new ingredients and check prices
- Determine portion sizes without experience with the dish
- Estimate trim loss from products you don't use often
- Quickly decide if the dish is profitable enough
The result? Most restaurant owners guess. "This probably costs around €8, so €28 should work." Until you discover at month's end that your daily specials have devoured your profit.
⚠️ Watch out:
Daily specials typically carry higher food costs than fixed dishes because you've got less purchasing and portioning experience. Budget accordingly.
Build an ingredient database
Quick food cost calculation requires an updated database of all ingredients with current prices. Not just main ingredients, but also:
- Basic ingredients: oil, butter, salt, pepper, spices
- Garnishes: parsley, lemon, microgreens
- Sauces: mayonnaise, ketchup, dressings
- Side dishes: potatoes, rice, vegetables
💡 Example database:
Store per ingredient:
- Salmon fillet: €32.00/kg (after trim loss)
- Butter: €6.80/kg
- Lemon: €0.15/piece
- Dill: €18.00/kg
- Olive oil: €8.50/liter
Now you can calculate new salmon dish costs in 5 minutes flat.
Work with standard portion sizes
Set standard portion sizes for each ingredient type. This eliminates weekly guesswork about quantities needed.
- Meat/fish main course: 150-200g
- Vegetables as side dish: 80-120g
- Potatoes/rice: 100-150g
- Sauce: 30-50ml
- Garnish: 5-10g
Adjust these through experience, but start with these guidelines. Better to estimate than skip calculations entirely. After managing kitchen operations for nearly a decade, I've seen too many operators lose money by avoiding this step.
💡 Example calculation:
Daily special: Grilled salmon fillet with dill butter sauce
- Salmon 180g: €32.00/kg = €5.76
- Butter 15g: €6.80/kg = €0.10
- Dill 2g: €18.00/kg = €0.04
- Lemon ¼ piece: €0.15 = €0.04
- Olive oil 5ml: €8.50/l = €0.04
Total food cost: €5.98
Set up a weekly routine
Every Monday (or whenever you plan daily specials) follow this process:
1. Check supplier prices (10 minutes)
Any price changes for this week's products? Update your database.
2. Calculate food costs for new dishes (15 minutes)
Add up all ingredients for each new dish using your standard portions.
3. Set selling prices (5 minutes)
Keep food cost under 35%. With €5.98 food cost you need at least €20.61 excl. VAT (€22.46 incl. VAT).
⚠️ Watch out:
Calendar this routine. Otherwise you'll forget and return to price guessing.
Adjust based on experience
After several weeks you'll spot patterns:
- Are you consistently using more or less of certain ingredients?
- Which dishes exceeded popularity expectations?
- Where were your food cost estimates off?
Adjust standard portions and prices using this data. Your system improves weekly.
💡 Example adjustment:
You notice guests expect larger portions with daily specials. Increase your standard meat/fish portion from 150g to 180g and adjust prices accordingly.
Digital vs. manual tracking
Run this system using:
Excel spreadsheet:
Create tabs for ingredients, standard portions and food cost calculations. It works but requires time to update.
Restaurant software like KitchenNmbrs:
Ingredient database, automatic food cost calculation and instant food cost percentages. Eliminates much calculation work.
Whatever method you choose, weekly system usage matters most. Consistency beats perfection.
How do you set up this system? (step by step)
Build your ingredient database
Create a list of all ingredients you use with current purchase prices per kg/liter/piece. Include basic ingredients like oil, spices and garnishes that you often forget to calculate.
Determine standard portion sizes
Set a standard portion size for each type of ingredient (meat 150-200g, vegetables 80-120g, etc.). This prevents you from having to guess every week how much you need.
Plan your weekly routine
Reserve 30 minutes every Monday to check supplier prices, calculate food costs for new dishes and set selling prices. Put this in your calendar as a standing appointment.
✨ Pro tip
Track your daily special sales velocity for 72 hours after launch. If a dish moves slower than expected, you can adjust portions or pricing before the week ends, protecting your food cost targets.

Frequently asked questions
How often should I update my ingredient prices?
Check prices weekly for ingredients you're using that week. For fixed ingredients you always use (oil, spices, basic products) monthly suffices, unless your supplier notifies you of price changes.
What if I estimate the portion size wrong?
Start with standard guidelines and adjust through experience. Better to estimate than skip calculations entirely. After several weeks you'll spot patterns and can adjust accordingly.
Can my food cost be higher for daily specials than for fixed dishes?
Yes, that's normal. With daily specials you have less purchasing and portioning experience. A food cost of 32-38% is acceptable, versus 28-35% for fixed dishes.
How do I prevent forgetting ingredients in my calculation?
Create a checklist of everything on the plate: main ingredient, sides, sauce, garnish, cooking oil, butter. That parsley and lemon slice cost money too.
What if my supplier raises prices mid-week?
Small increases (5-10%) you can usually absorb within your margin. With large increases (15%+) adjust selling price immediately or switch to alternative ingredients for the week.
Should I calculate food costs for garnishes and small portions?
Absolutely. Those microgreens, herb oils, and decorative elements add up quickly. A €0.50 garnish on 50 plates equals €25 weekly - that's real money.
How do I handle seasonal ingredient price fluctuations?
Build seasonal pricing into your database. Create separate entries for summer/winter prices on volatile items like tomatoes or asparagus. Adjust specials based on seasonal availability and costs.
