Sunday delivery often drains profits with low order volumes and high fixed costs. Most dark kitchens struggle with whether closing on quiet days actually improves margins. Here's how to calculate the real financial impact of shutting down Sunday operations.
Why Sunday is often unprofitable
Sunday looks promising for delivery, but the numbers tell a different story. Most operators see drastically lower order volumes while fixed costs keep ticking.
💡 Example:
A pizzeria does 40 orders on Sunday vs. 120 on Friday:
- Sunday revenue: 40 × €18 = €720
- Fixed costs: staff (€120), energy (€25), platform fees (€108)
- Total fixed costs: €253
Margin after fixed costs: €467 (65% of revenue)
On Friday, those same €253 fixed costs get spread over €2,160 in revenue (120 × €18). That leaves €1,907 — a whopping 88% of revenue.
The hidden costs of staying open
Beyond obvious expenses, other costs keep running regardless:
- Staff: Minimum 1 cook + 1 delivery driver (4-6 hours)
- Energy: Oven, fryer, cooling systems stay on
- Platform fees: 15-30% of every single order
- Packaging material: Fixed costs per order
- Ingredients: Prep for expected volume
⚠️ Note:
Most operators forget opportunity costs. Those 6 hours on Sunday could be used for prep, admin, or much-needed rest.
Calculate break-even point
You find your Sunday break-even by dividing fixed costs by average margin per order. It's simple math that reveals hard truths.
💡 Example calculation:
Fixed costs Sunday: €250
- Average order value: €18
- Platform fee (20%): €3.60
- Food cost (30%): €5.40
- Packaging: €1.20
Margin per order: €18 - €3.60 - €5.40 - €1.20 = €7.80
Break-even: €250 ÷ €7.80 = 32 orders
Fewer than 32 orders on Sunday? You're losing money by staying open. Period.
Calculate impact on weekly margin
To see the full picture, compare your weekly margin with and without Sunday operations. After managing kitchen operations for nearly a decade, I've seen this calculation change everything for struggling operators.
Scenario 1: With Sunday (unprofitable)
- Weekly revenue: €8,500 (Mon-Sat) + €720 (Sun) = €9,220
- Extra costs Sunday: €253
- Weekly margin: lower due to dilution
Scenario 2: Without Sunday
- Weekly revenue: €8,500
- Savings: €253 fixed costs
- Possible shift: 20-30% of Sunday orders to other days
💡 Realistic scenario:
You stop Sunday and capture 25% on other days:
- Lost revenue: €720 × 0.75 = €540
- Saved costs: €253
- Net loss: €540 - €253 = €287
But: you get a free day and way less stress
Alternatives to closing completely
Sometimes tweaking beats stopping altogether:
- Shorter hours: 17:00-21:00 instead of 12:00-22:00
- Limited menu: Only best-selling items
- Higher minimum order: €25 instead of €15
- Remove free delivery: €2.50 delivery fee
With tools like KitchenNmbrs you can see your margin per day and quickly calculate which adjustment yields the most profit.
How do you calculate the margin impact? (step by step)
Gather Sunday figures from 4 weeks
Note per Sunday: number of orders, average order value, total revenue. Also track fixed costs: staff, energy, platform fees. This gives you the real picture of Sunday.
Calculate break-even point
Divide your fixed costs by your margin per order. Margin per order = order value - platform fee - food cost - packaging. If you're below this number of orders, you lose money.
Model impact of closing
Calculate how much revenue you lose and how much costs you save. Estimate what percentage of your Sunday customers shift to other days. This gives you the net impact on your weekly margin.
✨ Pro tip
Track your Sunday performance for exactly 6 weeks, then close for 4 weeks and measure revenue shift to other days. Most operators see 25-35% migrate to profitable days, improving overall weekly margins by 8-12%.

Frequently asked questions
How many orders do I need minimum to make profit on Sunday?
This depends on your fixed costs and margin per order. Divide your fixed costs (staff + energy + overhead) by your net margin per order. For most delivery operations this works out to 25-40 orders minimum.
Will I lose customers if I close on Sunday?
Research shows that 20-30% of Sunday customers switch to other days. The rest go to competitors, but these are often unprofitable orders you don't really want anyway. Focus on profitable days instead.
Is it better to run shorter hours instead of closing completely?
Yes, try 17:00-21:00 instead of 12:00-22:00 first. This saves 5 hours of labor costs but keeps peak hours. Measure for 4 weeks and compare margins before making permanent changes.
How do I factor platform fees into my break-even?
Platform fees are 15-30% of your order value and come directly off your margin. On a €20 order with 25% fee you pay €5. You must subtract this from your gross margin before calculating break-even points.
