Data collection finished, but what happens next? Restaurant owners often find themselves buried under piles of spreadsheets without knowing which fire to put out first. Converting raw numbers into actionable weekly priorities makes all the difference.
Converting data into actionable steps
So your food cost analysis reveals dish A runs at 38% while dish B sits at 29%. That's useful information, but what's your next move? Success lies in ranking tasks by their financial impact.
💡 Example:
Your top 5 dishes this month:
- Steak: 45 portions, 35% food cost
- Salmon: 38 portions, 41% food cost
- Pasta: 52 portions, 28% food cost
- Chicken: 33 portions, 32% food cost
- Risotto: 28 portions, 38% food cost
Where should you focus first? The salmon - high food cost AND high sales volume.
The impact-matrix approach
Build a straightforward table with two columns: Units sold and Food cost percentage. Items with frequent sales AND elevated food costs demand immediate attention.
- High sales + high food cost: Address this week
- High sales + low food cost: Don't touch it
- Low sales + high food cost: Menu removal candidate
- Low sales + low food cost: Push harder in marketing
Weekly cost calculation
Transform monthly figures into weekly dollar amounts. This creates tangible urgency around each problem.
💡 Example calculation:
Salmon: 38 portions per month, food cost 41% instead of target 30%
- Selling price excl. VAT: €24.77
- Current ingredient costs: €10.16
- Target ingredient costs: €7.43
- Loss per portion: €2.73
Weekly bleeding: €2.73 × 9.5 portions = €26
Building your weekly action plan
Limit yourself to 3 dishes maximum each week. From years of working in professional kitchens, I've seen teams get overwhelmed trying to fix everything simultaneously. Pick the item bleeding the most cash weekly.
⚠️ Important:
Always work with pre-tax selling prices. That €27 menu price becomes €24.77 after removing 9% VAT. Skip this step and your calculations won't balance.
Specific actions for each dish
Every item on your priority list needs one clear intervention:
- Reduce portion size: Cut 20 grams of steak, save €1.20 per plate
- Swap ingredients: Different garnish or side dish
- Increase price: Add €2 to drop food cost by 6 percentage points
- Recipe modification: Cheaper components, maintain flavor profile
Tracking your results
Block out 15 minutes every Friday for progress review: have the numbers improved? Compare identical weeks from different months to avoid seasonal distortions.
💡 Practical tip:
Build a basic Excel with 4 columns:
- Dish
- Portions this week
- Food cost %
- Weekly cash loss in €
Sort by cash loss. Attack the top 3.
How do you create a priority list? (step by step)
Collect your top 10 best-selling dishes
Get your POS data from last month. Count how many times each dish was sold. Focus only on the top 10 - the rest has less impact.
Calculate the food cost per dish
Add up all ingredient costs per portion. Divide by selling price excl. VAT and multiply by 100. Anything above 35% is usually too high.
Calculate the weekly loss in euros
Take the difference between desired food cost (30%) and actual food cost. Multiply by number of portions per week. This gives you concrete amounts to work with.
✨ Pro tip
Document your current portion sizes with photos and weights before making adjustments. After 2 weeks, you'll have clear visual proof of changes and can verify quality standards remain consistent.

Frequently asked questions
How many dishes should I fix simultaneously?
Never more than 3 per week. Kitchen teams get overwhelmed beyond that number. Focus on the item with the highest weekly dollar loss first.
What about dishes that sell well but have low food costs?
Don't touch them. Your energy should go toward high-volume items with cost problems. Those deliver the biggest financial wins.
How quickly will I see results from my changes?
Compare the same week from the previous month to avoid seasonal variations. Most portion or recipe adjustments show impact within 7-10 days.
Should I worry about low-volume dishes with high costs?
Only if food costs exceed 45%. Otherwise, you'll spend more time fixing them than you'll save in ingredient costs.
Can this method work for beverage costs too?
Absolutely, but remember to use 21% VAT for alcoholic drinks in your calculations. The priority formula remains identical: volume × margin problem = urgency level.
What if changing a recipe affects taste quality?
Test modifications during slow periods first. Get feedback from 3-4 regular customers before rolling out changes completely.
How do I handle dishes with seasonal ingredient price swings?
Track your target food cost ranges rather than fixed percentages. Build in 3-5% flexibility for items with volatile ingredient costs like seafood or produce.
