Over 78% of restaurants report that delivery platforms now request additional promotional fees beyond standard commissions. These extra contributions can slash your profit margins if you accept them blindly. Here's exactly how to calculate what these promotional asks will do to your bottom line.
What are promotional contributions?
Beyond standard platform fees (typically 15-30%), delivery apps constantly pitch extra contributions for:
- Featured placement: Your restaurant at the top of the app
- Discount campaigns: Platform covers the discount, you pay part back
- Marketing campaigns: Extra visibility during busy periods
- Premium listing: Highlighted position in search results
These contributions typically add another 2% to 10% on top of your existing commission.
⚠️ Heads up:
Promotional contributions get pitched as "increased revenue opportunities", but they always reduce your margin per order. So you must calculate whether extra volume justifies the lower profitability.
Calculating the impact on your margin
To determine if a promotional contribution makes financial sense, calculate these three numbers:
- Your new total platform costs (standard fee + promotional contribution)
- Your margin per order with the additional costs
- The break-even point in extra orders
💡 Example calculation:
Your current numbers:
- Average order: €25.00
- Standard platform fee: 25% = €6.25
- Food cost + packaging: €8.50
- Margin per order: €25.00 - €6.25 - €8.50 = €10.25
With 5% promotional contribution:
- Total platform costs: 30% = €7.50
- New margin: €25.00 - €7.50 - €8.50 = €9.00
- Margin reduction: €1.25 per order (-12%)
Determining if promotional contributions pay off
A promotional contribution only makes sense if the additional revenue exceeds what you lose per order.
Formula:
Break-even extra orders = (Current orders × Margin reduction per order) / New margin per order
💡 Real-world example:
Using the previous example:
- Current orders per week: 100
- Margin reduction: €1.25 per order
- New margin: €9.00 per order
Break-even calculation:
- Weekly loss: 100 × €1.25 = €125
- Extra orders needed: €125 / €9.00 = 14 orders
- You need at least 14% more orders to break even
Hidden costs of promotional contributions
Beyond direct costs, promotional contributions create often-overlooked impacts:
- Kitchen strain: More orders means increased pressure and potentially extra staff
- Packaging costs rise: Higher volume = more packaging materials
- Quality risk: During peak times, quality can suffer, damaging reviews
- Customer dependency: Diners become accustomed to promotions and order less without discounts
One of the most common blind spots in kitchen management is underestimating how promotional surges affect food quality and staff burnout. The extra orders might boost revenue short-term, but poor reviews from rushed service can hurt long-term growth.
⚠️ Heads up:
Many platforms pitch promotional contributions as "temporary campaigns", but then request them regularly. Always calculate as if it's a permanent cost increase.
Alternative strategies
Rather than paying promotional contributions, consider:
- Adjust menu pricing: Offset higher platform costs through strategic price increases
- Build direct delivery: More direct orders = zero platform costs
- Create loyalty programs: Retain customers without platform dependency
- Diversify platforms: Spread risk and increase negotiating power
💡 Practical tip:
Always test promotional contributions for a limited period first (1-2 weeks). Track exactly how many additional orders you receive and whether this compensates for the reduced margin. Many restaurants accept these contributions hastily without properly analyzing the numbers.
How do you calculate the impact of a promotional contribution? (step by step)
Calculate your current margin per order
Subtract from your average order: platform fee, food cost, and packaging costs. This is your current margin per order that you use as your baseline.
Calculate your new margin with promotional contribution
Add the promotional contribution to your current platform fee and recalculate your margin per order. The difference shows you how much you lose per order.
Determine how many extra orders you need
Divide your total margin reduction per week by your new margin per order. This gives you the minimum number of extra orders you need to break even.
✨ Pro tip
Track your promotional contribution performance weekly for exactly 3 weeks, then make your decision. Calculate the true cost including extra labor and packaging - most restaurants only look at the percentage fee and miss these hidden expenses.

Frequently asked questions
Are promotional contributions calculated on the total order including delivery costs?
Usually only on the restaurant portion, not on delivery and service costs. Always verify this in the terms and conditions, as each platform has different rules. Some platforms calculate on gross order value while others exclude their own fees.
Can I raise my menu prices to compensate for promotional contributions?
Yes, but proceed carefully. A price increase of 5-10% often goes unnoticed by customers, but higher increases may drive them to competitors. Test gradual increases on select items first.
What happens to my margin if I stop paying the promotional contribution?
Your margin per order returns to normal levels, but you'll likely lose the extra visibility and thus orders. Plan ahead for how you'll retain customers without the promotion, perhaps through direct marketing or loyalty programs.
