Most restaurants see delivery expansion as pure opportunity. But while reaching new postcodes sounds profitable, longer drive times, increased fuel costs and extended labor hours can devastate your margins faster than you'd expect.
What changes in your cost structure?
Expanding your delivery radius hits three cost areas that directly impact margins:
- Extended drive times: Fewer deliveries completed per hour
- Additional fuel expenses: More kilometers drain your budget
- Increased labor costs: Drivers spend more time for identical revenue
⚠️ Heads up:
Platform fees (Thuisbezorgd, Uber Eats) remain the same percentage, but your additional costs stack on top. Always calculate your net remainder.
Calculate your current delivery costs per order
Before measuring expansion impact, you need baseline costs for your existing delivery zone:
- Average drive time: Complete round trip duration
- Fuel expenses: €0.25-€0.35 per kilometer (vehicle dependent)
- Driver hourly rate: Plus employer contributions
- Platform commission: 15-30% of order total
💡 Current situation example:
3km delivery radius, €25.00 average order:
- Drive time: 20 minutes round trip
- Fuel: 6 km × €0.30 = €1.80
- Wages: 20 min × €18/hour = €6.00
- Platform fee (25%): €6.25
Total delivery costs: €14.05 (56% of order value)
Calculate the extra costs of expansion
For your target postcode, estimate additional time and distance per delivery. Add these figures to existing costs:
💡 8km expansion example:
Same €25.00 order, distant location:
- Drive time: 35 minutes round trip (+15 min)
- Fuel: 16 km × €0.30 = €4.80 (+€3.00)
- Wages: 35 min × €18/hour = €10.50 (+€4.50)
- Platform fee: remains €6.25
New delivery costs: €21.55 (86% of order value!)
Determine your break-even point
Higher delivery costs demand increased average order values for profitability. Calculate your minimum requirement:
- Food cost: Unchanged percentage (typically 28-35%)
- Delivery costs: Rise with distance
- Platform commission: Same percentage
- Overhead expenses: Kitchen, utilities (unchanged)
💡 Break-even calculation:
Maintaining 15% net margin requires:
- Food cost: 30%
- Delivery costs: €21.55
- Platform fee: 25%
- Target margin: 15%
Minimum order value = €21.55 / (100% - 30% - 25% - 15%) = €71.83
Test with a small sample
Before full expansion, run a limited one-week test in the new area:
- Average order value: Do customers hit the €70+ threshold?
- Order volume: Sufficient demand to justify costs?
- Real drive times: Do estimates match reality?
⚠️ Heads up:
Most kitchen managers discover too late that traffic patterns vary dramatically throughout the week. Test across different days and times for accurate data.
Alternatives to expansion
If calculations don't support expansion, consider these revenue-generating options:
- Increase minimum order value: Fewer orders, higher profitability
- Distance-based surcharges: €2-4 extra for remote postcodes
- Restaurant partnerships: Share delivery costs with nearby establishments
- Peak-hour restrictions: Serve new areas only during high-demand periods
A food cost calculator (like KitchenNmbrs) tracks your per-dish margins, showing exactly what's left after delivery expenses.
How do you calculate the margin impact of delivery radius expansion?
Measure your current delivery costs per order
Calculate average drive time, fuel costs (€0.30/km), delivery driver hourly wage and platform fees. Add everything up and divide by number of orders for cost per delivery.
Estimate extra costs for new postcode
Measure distance and drive time to new area. Calculate extra fuel and labor time. Add to current costs for total cost per delivery.
Calculate required minimum order value
Divide total delivery costs by (100% - food cost% - platform fee% - desired margin%). This gives you the break-even order value for profitability.
Test for a week with limited availability
Only deliver to new area during peak hours. Measure actual drive times, order values and number of orders. Compare with your calculation.
Make decision based on data
If average order value is above your break-even and there's enough volume, you can expand. If not, consider alternatives like a delivery surcharge.
✨ Pro tip
Track your actual drive times across 14 different delivery windows during your first month of expansion. Evening rush hour can double your estimated travel time from 25 to 45 minutes.

Frequently asked questions
Which delivery costs should I include in my calculation?
Include drive time (as labor costs), fuel (€0.25-0.35/km), platform fees (15-30%) and vehicle expenses. Don't overlook wear, tear and insurance for self-managed deliveries.
Can I charge different prices per postcode?
Yes, many restaurants add delivery surcharges for distant areas (€2-5 extra). This approach offers more transparency than price increases and customers typically accept it.
What if my average order value is too low for profitability?
Raise minimum order values for the new area, introduce delivery surcharges, or restrict service to peak hours when customers order more. Sometimes refusing expansion proves more profitable.
