How do I calculate the margin on a delivery menu that I adjust seasonally?

📝 KitchenNmbrs · updated 14 Mar 2026

Your delivery margins drop 20-40% compared to dine-in due to platform fees and packaging costs. Seasonal ingredient price swings make accurate calculations even trickier. Master the real math behind delivery profitability and keep your margins healthy year-round.

Why delivery margins are different

Delivery menus face cost structures that dining rooms never deal with. Sure, you save on service staff wages, but several new expenses hit hard:

  • Platform fees (Deliveroo, Uber Eats): 15-30% of your order value
  • Packaging costs: containers, bags, cutlery, napkins
  • Delivery costs (if you deliver yourself)
  • Higher food cost due to seasonal fluctuations

Most operators miss these hidden costs completely. They think they're making money while actually bleeding cash every order.

⚠️ Note:

Platform fees get calculated on your selling price including VAT. This makes your actual margin lower than you'd expect.

Calculate platform fees correctly

Platform fees represent your biggest delivery expense. They're always calculated on your VAT-inclusive selling price, but your margin calculations should exclude VAT.

💡 Example platform fee:

You sell pasta for €16.50 incl. 9% VAT via Deliveroo (25% fee):

  • Platform fee: €16.50 × 0.25 = €4.13
  • Net receipt: €16.50 - €4.13 = €12.37 incl. VAT
  • Net receipt excl. VAT: €12.37 / 1.09 = €11.35

So you actually receive €11.35 excl. VAT, not €16.50

Include packaging costs

Packaging works like an ingredient that must be factored into your cost price. Add up every packaging component per dish:

  • Main container: €0.35 - €0.65
  • Sauce containers: €0.08 - €0.15 each
  • Cutlery set: €0.12 - €0.20
  • Napkin: €0.02 - €0.05
  • Carrier bag: €0.15 - €0.25

💡 Example packaging costs:

Pasta carbonara delivery:

  • Pasta container: €0.45
  • Parmesan sauce container: €0.12
  • Cutlery: €0.15
  • Napkin: €0.03
  • Carrier bag (shared): €0.08

Total packaging: €0.83 per portion

Handle seasonal adjustments

Ingredient prices swing wildly by season. Vegetables and fish can jump 30-50% during off-seasons. From analyzing actual purchasing data across different restaurant types, we've seen operators lose 15-20% margin overnight during seasonal transitions. You need to update your cost prices quarterly at minimum.

Seasonal margin formula:

Margin % = ((Net receipt excl. VAT - Ingredients - Packaging) / Net receipt excl. VAT) × 100

💡 Example seasonal margin winter vs summer:

Salad with tomatoes and cucumber:

Summer (cheap season):

  • Selling price: €12.50 → net receipt: €8.61 excl. VAT
  • Ingredients: €3.20
  • Packaging: €0.65
  • Margin: ((€8.61 - €3.85) / €8.61) × 100 = 55.3%

Winter (expensive season):

  • Selling price: €12.50 → net receipt: €8.61 excl. VAT
  • Ingredients: €4.80 (50% more expensive)
  • Packaging: €0.65
  • Margin: ((€8.61 - €5.45) / €8.61) × 100 = 36.7%

Target minimum margins for delivery

Delivery operations skip service costs but get hammered by platform fees. Aim for margins between 45-60% after all costs.

  • Below 40%: You're losing money
  • 40-45%: Break-even to slight profit
  • 45-60%: Healthy margin
  • Above 60%: Risk of pricing yourself out

⚠️ Note:

If your margin drops below 45%, raise prices or modify recipes. Platform fees aren't negotiable.

Plan price adjustments

Schedule your price changes ahead of time. Review monthly to check if your margins hold up, especially for seasonal items.

Many delivery operators use automated tracking systems to spot when margins drop due to supplier price increases.

How do you calculate the margin on your delivery menu? (step by step)

1

Calculate your net receipt

Deduct the platform fee from your selling price and convert to excluding VAT. Platform fee is calculated on the price including VAT, but you calculate your margin excluding VAT.

2

Add up all costs

Calculate what each dish really costs: ingredients + all packaging (containers, cutlery, napkins, carrier bag). Update these costs every month for seasonal products.

3

Calculate your margin percentage

Use the formula: ((Net receipt excl. VAT - Total costs) / Net receipt excl. VAT) × 100. Aim for a minimum 45% margin for healthy delivery operations.

✨ Pro tip

Track your 4 most seasonal dishes every 5 weeks during spring and autumn transitions. These periods create the biggest ingredient price swings that can destroy your delivery margins overnight.

Frequently asked questions

Should I include VAT in my margin calculation?

No, always calculate excluding VAT. Platform fees are calculated on the VAT-inclusive price, but you calculate your real margin excluding VAT.

What if my margin drops below 40%?

You're losing money at that point. Raise your prices or modify your recipes. Platform fees are fixed costs, so you need to save elsewhere or charge more.

How often should I adjust prices for seasonal products?

Review monthly to see if your margins still work. With major seasonal swings like winter tomatoes, adjust immediately or you'll lose money.

Can I charge different prices per platform?

Yes, you can. Many operators charge higher prices on platforms with steeper fees to maintain consistent margins.

Should I include delivery costs in my calculation?

If you deliver yourself, yes. If the platform handles delivery, no. Self-delivery runs approximately €3-5 per trip in fuel and labor.

How do I handle combo meals with mixed seasonal ingredients?

Calculate each component separately, then average the seasonal impact. Focus on the highest-cost ingredients that swing the most during off-seasons.
