How do I calculate revenue per occupied seat at a brunch service?

📝 KitchenNmbrs · updated 13 Mar 2026

Revenue per occupied seat determines whether your brunch service is profitable. Many entrepreneurs only look at turnover, but forget to calculate the costs per guest. In this article, you'll learn step-by-step how to calculate what each occupied seat truly generates.

What is revenue per occupied seat?

Revenue per occupied seat is the amount you keep per guest, after deducting all direct costs. It differs from revenue per guest because you subtract all costs directly related to that one guest.

💡 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 a fair calculation, you add up all direct costs you incur for that one guest:

  • Ingredient costs: Everything that goes on the plate, including garnish and bread
  • Service costs: Server time × hourly wage
  • Dishwashing costs: Estimated at €1-2 per guest (energy, supplies, time)
  • Disposable materials: Napkins, straws, packaging for takeaway

⚠️ Note:

Always calculate with 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 is simple, but the details make the difference:

Revenue per seat = Revenue per guest (excl. VAT) - Direct costs per guest

Where direct costs consist of:

  • Ingredient costs of the dish
  • Service costs (time × hourly wage)
  • Dishwashing and energy (estimate €1.50-2.00)
  • Disposable materials if 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

You calculate differently for buffet than for à la carte service:

À la carte brunch:

  • Higher service costs (more 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

Benchmarks and target figures

Common 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 are guidelines. Your own situation depends on rent, labor costs, and local market conditions.

What to do with the result?

Once you've calculated your revenue per seat, you can steer:

  • Revenue too low? Check your ingredient costs and portion size
  • High service costs? Consider a more efficient approach or buffet format
  • Much waste at buffet? Adjust quantities

With a system like KitchenNmbrs you can automate these calculations and immediately see which brunch arrangements generate the most revenue per occupied seat.

How do you calculate revenue per occupied seat? (step by step)

1

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.

2

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.

3

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

Check your revenue per seat at different times. Weekend brunch often generates more than weekday service, but also costs more staff.

Frequently asked questions

Should I include fixed costs like rent in the calculation?

No, revenue per seat is the contribution toward your fixed costs. Rent, insurance, and management costs are there anyway and aren't calculated per guest.

How do I estimate service costs per guest?

Add up: taking order (3 min), serving (2 min), refilling drinks (2 min), clearing and billing (5 min). Total approximately 12 minutes × hourly wage divided by 60.

What if guests stay much longer than planned?

Long sitting time increases your service costs and lowers your revenue per hour. Therefore also calculate your revenue per seat per hour to see the full picture.

How do I calculate this for a brunch buffet?

At buffet, service costs are lower (approximately €2-3 per guest), but ingredient costs are higher due to waste. Calculate with average consumption plus 15-20% waste.

What is good revenue per seat for brunch?

Aim for at least €10-15 per seat to cover your fixed costs. For premium brunch this can go up to €20-25 per occupied seat.
