Add-on products like bread, dips or extra sauces may seem small, but can deliver solid margins. The problem is that many entrepreneurs price these products 'by feel', which means they leave money on the table or earn too little. Here's how to calculate the exact margin on purchased products you sell as add-ons.
Why add-on margins matter
Add-ons are often pure profit. A roll you buy for €0.80 and sell for €2.50 has a much higher margin than your main courses. But only if you calculate it correctly.
💡 Example:
You sell a baguette as a side for €2.95 (incl. 9% VAT):
- Purchase price: €0.85 per piece
- Selling price excl. VAT: €2.95 / 1.09 = €2.71
- Margin in euros: €2.71 - €0.85 = €1.86
- Margin percentage: (€1.86 / €2.71) × 100 = 68.6%
That's an excellent margin!
The formulas you need
For add-on products you use the same formulas as for other products, but often with better results:
- Margin in euros = Selling price excl. VAT - Purchase price
- Margin percentage = (Margin in euros / Selling price excl. VAT) × 100
- Minimum selling price = Purchase price / (1 - Desired margin%)
⚠️ Note:
Always calculate with the selling price EXCLUDING VAT. The price on your menu is including 9% VAT for food.
Don't forget hidden costs
With purchased add-ons there are often extra costs you need to factor in. Most kitchen managers discover too late that these seemingly minor expenses can slash their margins by 15-20%:
- Heating: Gas or electricity for oven
- Packaging: Basket, paper, napkin
- Garnish: Butter, herbs, dip
- Labor: Time to heat and prepare
💡 Example with hidden costs:
Baguette add-on full cost price:
- Bread purchase: €0.85
- Butter portion: €0.15
- Heating (gas): €0.05
- Basket + paper: €0.10
Total cost price: €1.15 (was €0.85)
Margin becomes: (€2.71 - €1.15) / €2.71 = 57.6% (was 68.6%)
Different pricing strategies
For add-ons you have different options for pricing:
- High margin strategy: 60-80% margin, lower sales volume
- Volume strategy: 40-50% margin, more sales
- Bundle strategy: Lower margin on add-on, but sells main course
Add-ons as profit drivers
Well-priced add-ons can significantly improve your overall profitability. A roll with €1.86 profit compensates for much of the lower margins on main courses.
💡 Impact example:
If you sell 30 add-ons daily with €1.50 extra profit per piece:
- Per day: 30 × €1.50 = €45 extra profit
- Per week (6 days): €45 × 6 = €270
- Per year: €270 × 52 = €14,040 extra profit
Just by pricing add-ons correctly!
How do you calculate the margin on add-on products? (step by step)
Gather all costs
Add the purchase price to all extra costs like heating, garnish, packaging and labor time. This gives you the actual cost price of the add-on product.
Calculate your selling price excluding VAT
Divide your menu price by 1.09 to get the price excluding 9% VAT. Use this price to continue calculating your margin.
Calculate margin in euros and percentage
Subtract the cost price from the selling price excl. VAT for the margin in euros. Divide this by the selling price and multiply by 100 for the percentage.
Evaluate and optimize
Compare your margin with your target and see how much you're selling. Adjust the price if the margin is too low or test a lower price for more volume.
✨ Pro tip
Track your 5 most popular add-ons weekly and ensure each maintains at least 55% margin. A single high-volume add-on with poor margins can quietly drain €200-400 monthly from your bottom line.

Frequently asked questions
Should I include VAT in my margin calculation?
No, always calculate with the price excluding VAT. Divide your menu price by 1.09 to get the price excl. VAT and use that for your margin calculation.
What is a good margin for add-on products?
Add-ons can have higher margins than main courses. A margin of 50-70% is normal for purchased add-ons like bread, dips or extra portions.
Should I include labor time in the cost price?
For simple add-ons (heating bread) you can often ignore this. For more complex add-ons that take a lot of time, then factor in €15-20 per hour of labor.
How often should I check my add-on prices?
Check monthly whether your purchase prices have changed. Suppliers regularly raise prices and you need to pass that on in your selling prices.
Can I use add-ons to compensate for low margins?
Yes, that's a smart strategy. High margins on add-ons can compensate for lower margins on main courses and improve your overall profitability.
How do I handle add-ons that require special storage?
Factor in refrigeration or freezer costs if your add-ons need special storage. Cold storage adds roughly €0.02-0.05 per item per week to your costs.
Should I track add-on margins separately from main dishes?
Absolutely, track them separately since they often perform differently. Add-ons typically have higher margins but lower attachment rates than you might expect.
