📊 Restaurant Delivery Customer Acquisition Cost: Complete Guide 2026
Customer acquisition cost (CAC) is one of the most critical metrics for restaurant delivery businesses. Understanding your true CAC helps you make smarter marketing decisions, price your promotions correctly, and build a sustainable delivery operation.
What Is Customer Acquisition Cost for Delivery?
Customer acquisition cost (CAC) measures the total marketing and operational cost required to acquire one new paying customer. For restaurant delivery, this includes all expenses spent on advertising, promotions, discounts, and platform fees to attract new orders.
How to Calculate Your Delivery CAC
Calculating your exact CAC requires tracking all acquisition-related expenses over a specific period:
CAC Formula
CAC = Total Acquisition Costs ÷ Number of New Customers Acquired
What to Include in Acquisition Costs
- Platform advertising: DoorDash Promoted Listings, UberEats Ads, Grubhub promotions
- Social media ads: Facebook, Instagram, TikTok advertising costs
- Discounts and promotions: First-order discounts, coupon costs, free delivery offers
- Referral costs: Customer referral program rewards
- Commission premiums: Extra fees paid for priority placement
- Marketing agency fees: If you outsource delivery marketing
Delivery CAC by Channel
| Acquisition Channel | Average CAC | Notes |
|---|---|---|
| Platform Ads (DoorDash/UberEats) | $6-12 | High intent, ready to order |
| Social Media Ads | $8-18 | Brand awareness + conversions |
| First-Order Discounts | $5-10 | Effective but costly |
| Referral Programs | $3-7 | Highest ROI when working |
| Organic Search (SEO) | $2-5 | Long-term, sustainable |
| Email Marketing | $1-3 | Lowest CAC channel |
What Is a Good Delivery CAC?
A healthy delivery business should target a Customer Lifetime Value (LTV) to CAC ratio of at least 3:1. This means if it costs you $10 to acquire a customer, they should generate at least $30 in lifetime revenue.
For example, if your average delivery order is $35 and customers order 2 times per month for 12 months:
- LTV = $35 × 2 × 12 = $840
- Target CAC = $840 ÷ 3 = $280 max
5 Strategies to Reduce Delivery CAC
1. Build Direct Ordering
Encourage customers to order directly through your website or app. Direct orders eliminate platform fees (15-30%) and reduce long-term CAC. Promote your direct ordering URL on all packaging and receipts.
2. Implement a Referral Program
Customer referrals have the lowest CAC and highest conversion rates. Offer existing customers incentives ($5 credit, free dessert) to refer friends. Track referrals with unique promo codes.
3. Focus on Retention
It's 5x cheaper to retain an existing customer than acquire a new one. Implement loyalty programs, personalized email marketing, and exclusive offers for repeat customers to increase retention.
4. Optimize Platform Ad Spend
Use platform analytics to identify which ad campaigns deliver the lowest CAC. Focus budget on high-performing keywords and menu items. Test different ad formats and bidding strategies.
5. Leverage User-Generated Content
Encourage customers to share photos and reviews on social media. This organic content costs nothing to produce and builds social proof that drives new customer acquisitions.
Measuring and Tracking CAC

- New vs. returning customer orders (use platform analytics)
