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.

Key Insight: The average restaurant spends $8-15 to acquire a single delivery customer. Understanding this number is essential for profitability.

What Is Customer Acquisition Cost for Delivery?

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

To effectively manage your delivery CAC, implement tracking for:

  • New vs. returning customer orders (use platform analytics)
  • Conversion rates by acquisition channel
  • Customer lifetime value by acquisition source
  • Monthly trends in acquisition costs
Pro Tip: Calculate your CAC monthly and compare it against industry benchmarks. If your CAC is trending up, it's time to optimize your marketing mix or focus more on retention.
