Selling pizzas by the slice or whole makes a huge difference for your profit. Many pizzerias calculate incorrectly and lose money on their slices. You'll learn exactly how to calculate the cost price for both sales methods.
The difference between whole pizza and slice cost price
A whole pizza has one cost price. But as soon as you cut it into pieces, the calculation changes. You need to account for waste, edge pieces, and the number of slices you actually sell.
💡 Example: Margherita pizza
Ingredients whole pizza (32cm):
- Dough: €0.85
- Tomato sauce: €0.45
- Mozzarella: €2.20
- Basil + oil: €0.30
Total cost price: €3.80
Calculate cost price per slice
A 32cm pizza is usually cut into 8 pieces. But not all pieces are the same size and not all pieces are always sold.
- Theoretical slice cost price: €3.80 / 8 = €0.48 per slice
- Actual slice cost price: Higher due to waste and unsold pieces
- Waste factor: Add 10-15% for pizzas that aren't completely sold
⚠️ Note:
Edge pieces and last slices often remain unsold. Calculate with 85-90% sales of your cut pizzas, not 100%.
Actual slice cost price formula
Use this formula for a realistic slice cost price:
Slice cost price = (Whole pizza cost price / Number of slices) × Waste factor
💡 Example calculation:
Margherita pizza €3.80, 8 slices, 15% waste:
- Basic slice cost price: €3.80 / 8 = €0.48
- With waste: €0.48 × 1.15 = €0.55
Actual slice cost price: €0.55
Determine selling price per method
Your sales strategy determines which method is more profitable:
- Whole pizza: Fixed margin, no waste, higher revenue per customer
- Per slice: Lower threshold, more impulse sales, but higher cost price due to waste
- Combination: Whole pizzas during busy times, slices for in-between
VAT and final price calculation
Pizzas fall under 9% VAT. Always calculate your food cost based on the price excluding VAT. From analyzing actual purchasing data across different restaurant types, the most successful pizzerias consistently track both methods separately.
💡 Example pricing:
Slice cost price €0.55, desired food cost 28%:
- Minimum price excl. VAT: €0.55 / 0.28 = €1.96
- Price incl. 9% VAT: €1.96 × 1.09 = €2.14
- Rounded: €2.25 per slice
Food cost check: €0.55 / €2.06 = 26.7% ✓
Practical tips for slice sales
Slice sales have different challenges than whole pizzas:
- Keeping warm: Quality deteriorates, but throwing away costs money
- Timing: Make fresh pizzas during busy times
- Variety: Popular flavors more often, specials less frequently
- Portion size: Consistent pieces ensure fair pricing
How do you calculate pizza cost price? (step by step)
Calculate whole pizza cost price
Add up all ingredients: dough, sauce, cheese, toppings, herbs and oil. Don't forget small ingredients like salt or oregano.
Determine number of slices and waste factor
Count the number of pieces you cut into. Add 10-15% for waste from unsold slices and edge pieces that remain.
Calculate actual slice cost price
Divide the cost price by the number of slices and multiply by the waste factor. This is your actual cost price per slice.
Determine selling price with desired margin
Divide your slice cost price by your desired food cost percentage. Add 9% VAT for the final price on your menu.
✨ Pro tip
Track your slice sales for 2 weeks to identify which pieces sell first versus last. This data helps you optimize production timing and reduce waste by 20-30%.

Frequently asked questions
Should I include VAT in my pizza cost price?
No, always calculate your food cost based on the selling price excluding VAT. Pizzas have 9% VAT in the Netherlands.
How much waste should I calculate for slice sales?
Calculate with 10-15% waste. Edge pieces and last slices often remain unsold, especially with less popular flavors.
Is slice sales more profitable than whole pizzas?
That depends on your situation. Slices have a lower threshold but higher cost price due to waste. Whole pizzas generate more revenue per customer.
How often should I adjust my pizza prices?
Monitor your ingredient prices monthly, especially cheese and meat. These can fluctuate significantly and affect your margin.
What is a good food cost for pizzas?
For pizzas, 25-30% food cost is standard. Slices can be slightly higher due to waste, whole pizzas usually lower.
Should I cut all pizzas the same way for slice sales?
Yes, consistent cutting ensures uniform portions and accurate costing. Use a pizza wheel or rocker knife for even 8-slice portions on 32cm pizzas.
