Revenue per occupied seat works like a profit thermometer for each brunch guest - it shows what's left after covering all the direct costs of serving them. Most restaurant owners focus only on total sales, missing the real story of per-guest profitability. Here's how to calculate what each occupied seat actually puts in your pocket.
What is revenue per occupied seat?
Revenue per occupied seat shows the actual amount you keep per guest after subtracting all direct costs. It's different from revenue per guest because you're removing every cost tied specifically to serving that person.
? Example:
Brunch guest orders for €28.50 (incl. 9% VAT):
- Revenue per guest: €28.50
- Ingredient costs: €8.50
- Service (15 min at €18/hour): €4.50
- Other costs: €2.00
Revenue per seat: €28.50 - €15.00 = €13.50
Which costs do you include?
For accurate calculations, you'll add up every direct cost that guest creates:
- Ingredient costs: Everything that touches the plate, plus garnish and bread
- Service costs: Server time × hourly wage
- Dishwashing costs: Usually €1-2 per guest (energy, supplies, labor)
- Disposable materials: Napkins, straws, takeaway containers
⚠️ Note:
Always calculate using revenue excl. VAT. For brunch that's 9% VAT, so €28.50 becomes €26.15 excl. VAT for your calculation.
Revenue per seat formula
The formula looks straightforward, but accuracy in the details matters:
Revenue per seat = Revenue per guest (excl. VAT) - Direct costs per guest
Your direct costs include:
- Ingredient costs of the dish
- Service costs (time × hourly wage)
- Dishwashing and energy (estimate €1.50-2.00)
- Disposable materials when applicable
? Practical example:
Brunch buffet at €24.95 per person:
- Revenue excl. VAT: €22.89
- Buffet ingredients per guest: €7.50
- Service (less intensive): €2.50
- Dishwashing and energy: €1.75
Revenue: €22.89 - €11.75 = €11.14 per seat
Difference between à la carte and buffet
Buffet and à la carte services require different calculation approaches:
À la carte brunch:
- Higher service costs (more guest interaction)
- Variable ingredient costs per dish
- More dishwashing per guest
Buffet brunch:
- Lower service costs per guest
- Fixed ingredient costs (calculate average consumption)
- More waste, but less dishwashing per guest
From years of working in professional kitchens, I've seen buffets work better for high-volume weekend services, while à la carte gives you more control over food costs during slower periods.
Benchmarks and target figures
Typical revenue per seat at brunch services:
- Budget brunch (€15-20): €8-12 revenue per seat
- Mid-range brunch (€20-30): €12-18 revenue per seat
- Premium brunch (€30+): €18-25 revenue per seat
⚠️ Note:
These figures serve as guidelines. Your actual results depend on rent, labor costs, and local market conditions.
What to do with the result?
Once you've calculated revenue per seat, you can make targeted improvements:
- Revenue too low? Examine your ingredient costs and portion sizes
- High service costs? Consider more efficient service methods or buffet format
- Excessive buffet waste? Adjust food quantities
Using tools like KitchenNmbrs can automate these calculations and instantly show which brunch options generate the highest revenue per occupied seat.
How do you calculate revenue per occupied seat? (step by step)
Determine revenue per guest excl. VAT
Take the price of your brunch menu and divide by 1.09 to remove the VAT. At €28.50 incl. VAT this becomes €26.15 excl. VAT. This is your basis for the calculation.
Add up all direct costs per guest
Calculate ingredient costs, service costs (time × hourly wage), dishwashing costs and any disposable materials. Estimate service costs at 10-20 minutes per guest for à la carte service.
Subtract costs from revenue
Revenue excl. VAT minus all direct costs gives you the revenue per occupied seat. This amount must cover your fixed costs (rent, energy, management) and generate profit.
✨ Pro tip
Track your revenue per seat during peak versus off-peak hours - Saturday brunch typically generates €3-5 more per seat than weekday service, but requires 25% more staff coverage.
