Number discussions turn into heated arguments because everyone's working with different definitions. You calculate with VAT, your chef doesn't. He claims food cost is 25%, you get 35%. These conflicts drain energy and waste time.
Why number discussions go wrong
The real issue isn't the numbers - it's that everyone's using different rules. Your food cost calculation uses today's prices. The chef pulls numbers from three weeks ago. You both think the other person's wrong, but you're just measuring different things.
⚠️ Watch out:
Without clear definitions, number talks become personal battles. Everyone's defending their method instead of solving the actual problem.
Create shared definitions
Start by agreeing on what each term means. Write these down and make sure everyone uses them:
- Food cost: excludes VAT, includes every ingredient that touches the plate
- Selling price: VAT-free for calculations, VAT-included on customer menus
- Portion size: recipe amounts, not what actually gets served
- Purchase price: most recent supplier invoice, delivery costs included
💡 Example:
Before discussing steak costs, establish the baseline:
- Menu price: €32.00 with VAT = €29.36 without VAT
- Meat portion: exactly 200g per recipe
- Current meat cost: €24.00/kg from last invoice
- Sides included: potatoes, vegetables, sauce
Now everyone calculates the same way and gets identical results.
Establish discussion ground rules
After managing kitchen operations for nearly a decade, I've learned that clear meeting rules prevent most number conflicts:
- Single data source: one price list for everyone, no personal estimates
- Fresh data only: prices can't be older than 30 days
- Complete costing: include everything - oil, spices, garnishes
- Facts over feelings: numbers aren't criticism of anyone's work
- Show your work: explain calculation methods before presenting results
💡 Example agreement:
"Monday meetings cover previous week's performance. We use monthly-updated prices from our system. Disagreements require showing alternative data sources and reasoning."
Make calculations transparent
Show the team exactly how you reached each number. Nobody should have to guess your methodology:
- List every ingredient you counted
- Reference specific invoices and suppliers
- Justify any assumptions you made
- Welcome questions and requests for clarification
Standardize calculation tools
Everyone should use identical systems for number-crunching. This eliminates confusion about which prices or formulas someone applied. Tools like KitchenNmbrs ensure the whole team sees consistent cost data and follows the same calculation logic.
⚠️ Watch out:
Individual Excel spreadsheets guarantee different results. That breeds frustration and destroys confidence in your financial data.
Schedule routine number reviews
Don't wait for problems to discuss finances. Build regular check-ins into your team rhythm:
- Weekly: food costs for top-performing dishes
- Monthly: overall margins and trend analysis
- Quarterly: menu pricing updates and new item costs
Regular reviews normalize financial conversations. They become routine business discussions instead of stressful confrontations.
How do you set up number agreements? (step by step)
Define the basic concepts together
Go through the most important terms with your team: food cost, selling price, portion size. Make sure everyone understands the same thing by these concepts. Write down the definitions and hang them in the kitchen.
Choose one source for prices and recipes
Determine where you keep the current purchase prices and recipes. This can be an app, a shared document, or a folder with invoices. Everyone uses the same source, no personal estimates.
Make agreements about meeting times
Schedule fixed times to discuss numbers. For example, every Monday morning 15 minutes for last week's numbers. Make clear who prepares what and how calculations are presented.
✨ Pro tip
Pick your most popular dish and calculate its cost together as a team within the next 48 hours. Once everyone agrees on that single calculation, expand the same method to 5 more dishes.

Frequently asked questions
What if my chef disagrees with my food cost calculation?
Ask them to walk through their calculation step-by-step. Compare your data sources and portion assumptions. Usually you'll find you're using different prices or measuring different things entirely.
How often should we update our pricing data for discussions?
Refresh purchase prices monthly minimum, or immediately after major supplier increases. Never rely on pricing data that's more than 6 weeks old.
Should all staff members see our complete financial numbers?
Access depends on their role and responsibilities. Chefs need cost data for recipe development, but servers only need to know which items drive the most profit.
