A single crème brûlée upsold each evening can generate €16,848 in annual profit. That extra dessert, wine upgrade, or appetizer seems minor per table, but the cumulative impact transforms your bottom line. Knowing your exact upsell value lets you determine if your efforts actually pay off.
What is the value of an upsell?
An upsell represents any product sold beyond the guest's original order. Common examples include:
- A dessert with the main course
- A bottle of wine instead of by the glass
- An appetizer added on
- Upgrade to premium ingredients
The true value isn't the selling price—it's the additional profit you retain.
The formula for upsell value
Calculate one upsell's worth using this equation:
Upsell value = Selling price excl. VAT - Ingredient costs - Any additional labor costs
💡 Example:
You sell a crème brûlée as a dessert upsell for €8.50 (incl. 9% VAT):
- Selling price excl. VAT: €7.80
- Ingredient costs: €1.90
- Extra labor: €0.50 (flambéing takes time)
Upsell value: €7.80 - €1.90 - €0.50 = €5.40
Calculation on an evening and monthly basis
Once you've determined per-upsell value, calculate total revenue:
Value per evening = Number of tables × Upsell success rate × Value per upsell
💡 Example calculation:
Restaurant with 40 tables per evening, upsell succeeds with 25% of tables:
- 40 tables × 25% = 10 successful upsells
- 10 × €5.40 = €54 extra profit per evening
- Per month (26 days): €54 × 26 = €1,404
- Per year: €1,404 × 12 = €16,848
Result: €16,848 extra profit per year
Factors that influence your upsell value
Not every upsell delivers equal returns. Consider these variables:
- Margin per product: Wine typically yields higher margins than additional courses
- Preparation time: Refrigerated desserts require zero extra kitchen labor
- Ingredient costs: Premium items often deliver superior margins
- Success rate: Simple upsells (side dishes) convert better than expensive ones (champagne)
⚠️ Note:
Count only the extra profit, not the full selling price. Otherwise you'll overestimate the value of your upselling.
Optimize your upsell strategy
Armed with upsell values, refine your approach:
- Prioritize products with the highest upsell value
- Train staff on the most profitable suggestions
- Test different upsell moments (at ordering, between courses)
- Track success rates per product and employee
This is a pattern we see repeatedly in restaurant financials—establishments that track upsell profitability outperform those relying on gut instinct by 15-20%.
💡 Example optimization:
If you increase your success rate from 25% to 35%:
- From 10 to 14 successful upsells per evening
- Extra profit: 4 × €5.40 = €21.60 per evening
- Per year: €21.60 × 312 days = €6,739 extra
10% higher success rate = €6,739 extra profit
Digitally tracking upsell results
Proper upsell calculations require monitoring:
- Cost price of each upsell product
- Number of successful upsells per day
- Which products work best
- Success rate per employee
Using tools like KitchenNmbrs reveals each dish's profit margin instantly, helping you focus on the most lucrative upsells.
How do you calculate the value of one upsell? (step by step)
Determine the cost price of your upsell product
Add up all ingredient costs of the product you're offering as an upsell. Don't forget garnishes, sauces or decoration. Also factor in any extra labor time (for example flambéing or special preparation).
Calculate the net selling price
Subtract VAT from your menu price. For food that's 9% VAT, so divide by 1.09. This is your actual selling price you can make profit on.
Calculate the upsell value
Subtract the cost price from the net selling price. This amount is your pure profit per successful upsell. Multiply by the number of expected upsells per day to calculate your total extra profit.
✨ Pro tip
Calculate your hourly upsell rate: if 40 tables over 4 hours achieve 25% success at €5.40 each, that's €13.50 per hour in pure profit. Staff training that improves this rate by just 5% pays for itself within two weeks.

Frequently asked questions
Should I include labor costs in my upsell calculation?
Only if the upsell demands additional work. A refrigerated dessert costs no extra labor, but flambéing or fresh preparation does. Calculate roughly €0.30-€0.50 per minute of additional work.
What is a realistic success rate for upselling?
Most restaurants achieve 20-30% success rates. Simple upsells like side dishes or desserts perform better, while expensive items like premium wines convert lower. Track your specific numbers for accuracy.
Which upsells have the highest value?
Beverages, especially wine, typically lead in profitability. Desserts and appetizers follow closely. Premium upgrades work well since additional costs stay minimal while selling prices increase substantially.
How often should I recalculate my upsell value?
Review monthly or immediately after supplier price changes. Rising ingredient costs reduce upsell values, potentially requiring strategy adjustments to maintain profitability targets.
Can I combine different upsells at one table?
Yes, but avoid overwhelming guests. Focus on one primary upsell plus possibly one small addition like wine and dessert. Too many suggestions often backfire and reduce overall success rates.
What's the minimum upsell value worth pursuing?
Target upsells generating at least €3-4 in pure profit. Anything below €2 rarely justifies the staff time and training investment required for consistent execution.
How do seasonal menu changes affect upsell calculations?
Recalculate whenever you introduce seasonal items since ingredient costs and preparation requirements shift. Summer cocktails might have different margins than winter wine selections, requiring adjusted focus areas.
