Third-Party Marketplace Economics: How to Calculate Net Profit Per Delivery Order

The true cost of delivery orders goes far beyond platform commission. Learn how to calculate net profit per order across DoorDash, Uber Eats, and Grubhub — and which numbers actually matter.

Most restaurant operators know their rough commission rate. Few know their true net profit per delivery order. The difference is substantial — and it changes which platforms you should be on, which menu items you should promote, and whether delivery is actually working for your business.

This guide gives you the full picture. We'll walk through every cost component, show you the math with real numbers, and give you a reusable framework for evaluating every order that comes through your digital doors.

The Hidden Cost Stack of a Delivery Order

Platform commission is the line item everyone sees. But it's rarely the largest cost driver. Here's what actually eats into delivery profitability:

The Full Net Profit Per Order Formula

Here's the complete formula. Don't panic — we'll walk through examples next.

Each line item is expressed as a percentage of order value (for percentage-based costs) or a fixed dollar amount (for packaging and per-order labor). Converting everything to percentages makes comparison across platforms and menu items straightforward.

Worked Example: $35 Delivery Order on DoorDash

Let's walk through a mid-tier independent restaurant on DoorDash with a 25% commission rate. Order value: $35.

On paper, a $35 order with 25% commission looks manageable. After the full cost stack, you're at 22% margin — $7.73 profit on a $35 order. That number looks decent until you realize the same kitchen, making a dine-in or takeout order at $35, would net $18–22 after only food cost and packaging.

Delivery isn't inherently unprofitable. But operators who only look at commission rates are flying blind.

Same $35 Order: DoorDash vs Uber Eats vs Direct

The direct ordering channel doesn't eliminate food cost, packaging, or labor — but removing the 22–25% platform commission and promotion subsidies jumps margin from ~22% to ~57%. That's the lever most operators underuse.

Platform Fee Optimization: Getting to 15%

You can't eliminate platform fees, but you can reduce them. Commission rates are negotiable — here's how:

• Volume commitment: Most platforms offer 15–18% rates for restaurants committing to 150+ orders/month. Calculate whether the volume commitment makes sense for your operation.
• Direct ordering offset: Shift 15–20% of platform orders to direct. This reduces platform dependency and can improve your negotiating position (you need them less).
• Performance tier: Platforms reward high-performing restaurants with better rates. Respond to all customer issues promptly, maintain menu accuracy, and keep your operating hours current.
• Multi-brand leverage: If you run multiple virtual brands from one kitchen, negotiate platform rates across your brand portfolio, not per-brand.

Our Platform Fee Audit reviews your current contracts and identifies exactly where you can push rates down — typically saving 15–23% on platform costs.

Menu-Level Profitability: Not All Items Are Created Equal

A platform's effective commission is fixed, but your food cost varies wildly by item. A $12 burger that costs $3.50 in food has a 29% food cost — fine. A $12 pasta dish that costs $4.80 has a 40% food cost — that's eating your margin alive on every platform order.

Calculate contribution margin per item on every delivery menu item:

High food cost items don't belong on delivery unless your brand commands premium pricing. See our Menu Engineering guide for a full framework on scoring and selecting delivery menu items.

The Direct Ordering ROI: Real Numbers

Every 10% of orders you shift from DoorDash to direct ordering has meaningful impact. Here's the math for a restaurant doing $30,000/month on DoorDash at 25% commission:

Setting up direct ordering on your website takes 1–2 weeks with our First-Party Online Ordering service. The ROI is typically under 60 days.

Your Weekly Marketplace Economics Checkup

Run this check every Monday morning. It takes 15 minutes and keeps you from being surprised at the end of the month.

1. Pull your platform settlement reports for the prior week. Calculate total revenue, total fees paid, and effective commission rate per platform.
2. Calculate net revenue per platform = Gross Revenue − Commission − Promotions − Refunds. Compare to prior week and prior month.
3. Spot-check 5 random orders from each platform. Walk through the full cost stack manually to verify your estimates are tracking reality.
4. Flag any order with unusual fees — large refunds, promotional subsidies, or chargebacks. Investigate and dispute where warranted.
5. Check direct ordering volume. If it's below 10% of total delivery revenue, set a goal to reach 15% within 60 days.

Key Metrics to Track

Bottom Line

Platform economics aren't abstract. They're the difference between a delivery channel that contributes to your business and one that keeps you busy while someone else collects the margin.

Run the math on every platform. Optimize your delivery menu for contribution margin, not just popularity. Shift volume to direct ordering wherever the customer relationship will support it. And negotiate your commission rates annually — or whenever your volume justifies a better tier.
