Here's what most caterers discover too late: that 15% agency commission just turned your healthy 40% margin into barely breaking even. Event agencies typically charge 10-25% commission on your total catering price. You need to calculate your actual profit margin after deducting this commission, or you'll be working for free.

What is an event agency commission?

Event agencies act as intermediaries between you and the client. They charge a percentage of your quote as commission. This can be:

  • 10-15% for smaller agencies
  • 15-20% for established agencies
  • 20-25% for exclusive agencies

This commission comes off your revenue, not your profit. That makes calculating your actual margin absolutely critical.

⚠️ Important:

Always calculate the commission on your total quote amount, including staff and materials. Not just on food costs.

The formula for margin after commission

You calculate your actual margin in three steps:

Step 1: Net revenue = Gross quote - Agency commission

Step 2: Total costs = Food + Staff + Materials + Transport

Step 3: Actual margin % = ((Net revenue - Total costs) / Net revenue) × 100

? Example:

You quote €5,000 for a corporate lunch (50 people). The agency charges 15% commission.

  • Gross quote: €5,000
  • Agency commission: €5,000 × 15% = €750
  • Net revenue: €5,000 - €750 = €4,250

So you actually keep €4,250 from your €5,000 quote.

Cost calculation for catering

For a complete cost calculation, add up all your costs:

  • Food costs: Ingredients per person × number of people
  • Staff: Chefs and servers on-site
  • Materials: Dishes, linens, warming equipment
  • Transport: Fuel, time, wear and tear
  • Overhead: Insurance, administration (usually 5-10%)

One of the most common blind spots in kitchen management is forgetting to factor transport time into your labor costs. That 2-hour round trip isn't free.

? Complete example:

Corporate lunch for 50 people, quote €5,000, agency commission 15%:

  • Net revenue: €5,000 - €750 = €4,250
  • Food costs: €18/person × 50 = €900
  • Staff: 2 people × 6 hours × €25 = €300
  • Materials: €200
  • Transport: €150
  • Overhead: €200

Total costs: €1,750

Profit: €4,250 - €1,750 = €2,500

Actual margin: (€2,500 / €4,250) × 100 = 58.8%

When does it become unprofitable?

With high commission percentages, your margin can disappear quickly. Watch for these warning signs:

  • Margin below 30% after commission
  • Commission higher than your profit
  • Agency requires upfront payment but you have to pre-finance

⚠️ Important:

With commissions above 20%, you often need to increase your quote by 25-30% to maintain the same margin. Check if you're still competitive at that price.

Alternative agreements with agencies

Sometimes you can negotiate better deals:

  • Fixed fee: €X per event instead of a percentage
  • Tiered pricing: Lower commission with more events per year
  • Exclusivity: Lower commission if you become their preferred caterer

? Fixed fee example:

Agency charges €300 fixed fee instead of 15% commission:

  • On €2,000 quote: €300 (15% would be €300)
  • On €5,000 quote: €300 (15% would be €750)
  • On €10,000 quote: €300 (15% would be €1,500)

The higher your average quote, the more advantageous a fixed fee becomes.

How do you calculate your margin after agency commission? (step by step)

1

Calculate your net revenue

Subtract the agency commission from your gross quote. With a €5,000 quote and 15% commission, you keep €4,250 net revenue. This is the amount you calculate your margin on.

2

Add up all your costs

Calculate: food costs + staff + materials + transport + overhead. Don't forget hidden costs like extra travel time or special equipment. Add everything up for your total cost price.

3

Calculate your actual margin percentage

Use the formula: ((Net revenue - Total costs) / Net revenue) × 100. This gives you your actual margin after deducting the agency commission. Aim for a minimum of 25-30% margin.

✨ Pro tip

Frequently asked questions

Do I have to pay VAT on the agency commission?
Yes, the agency commission is subject to 21% VAT. The agency invoices you including VAT, and you can reclaim this VAT as a business owner.
Can I pass the commission on to the client?
Usually not directly. You can increase your quote to compensate for the commission, but it needs to stay competitive. Test what the market will accept.
When is working with an agency not profitable?
If your margin drops below 25% after commission, or if you're paying more in commission than you're making in profit. Then it's better to find clients directly.
How do I negotiate the commission percentage?
Offer exclusivity, volume agreements, or quick payment in exchange for lower commission. Agencies value reliable partners and are often willing to negotiate.
Should I ask for upfront payment on agency jobs?
Yes, ask for at least 50% upfront. You often have to pre-finance while the agency pays after completion. This protects your cash flow and limits your risks.
What if the guest count changes after I've agreed to the commission?
Most agencies calculate commission on the final invoice amount, not the original quote. So if guest count drops from 100 to 80, your commission drops too. Always clarify this upfront.
