To find your Customer Acquisition Cost (CAC) on Amazon, you need to calculate the total spend on efforts to attract new customers and then divide that by the number of new customers you successfully acquired. This metric is crucial for Amazon sellers to understand the efficiency of their marketing investments and optimize profitability.
What is CAC and Why is it Important for Amazon Sellers?
Customer Acquisition Cost (CAC) represents the average cost of acquiring a new customer. For Amazon sellers, understanding CAC helps in evaluating the effectiveness of advertising campaigns, promotional strategies, and overall marketing efforts. A lower CAC indicates more efficient spending and potentially higher profit margins.
The basic formula for calculating CAC is:
$$ \text{CAC} = \frac{\text{Total Acquisition Costs}}{\text{Number of New Customers Acquired}} $$
Breaking Down CAC for Amazon
Calculating CAC on Amazon involves identifying all relevant acquisition costs and accurately counting new customers within the Amazon ecosystem.
1. Identifying Total Acquisition Costs
These are all the expenses incurred to attract new customers to your Amazon products or brand.
- Amazon Advertising Costs:
- Sponsored Products: Pay-per-click (PPC) ads for individual product listings.
- Sponsored Brands: Ads featuring your brand logo, custom headline, and multiple products.
- Sponsored Display: Audience-based ads that appear on Amazon and external websites.
- Amazon DSP (Demand-Side Platform): Programmatic advertising for larger brands.
- Where to find: Amazon Advertising console reports.
- Promotional Costs:
- Coupons and Deals: The cost of discounts given to customers through Amazon's coupon or deal programs, especially those designed to attract first-time buyers.
- Promotional Bundles: Costs associated with multi-buy promotions if aimed at new customer acquisition.
- Where to find: Seller Central promotions and advertising reports.
- External Marketing Costs (driving traffic to Amazon):
- Social Media Ads: Facebook, Instagram, TikTok ads driving traffic to your Amazon listings.
- Google Ads: Search engine marketing campaigns directing to Amazon.
- Influencer Marketing: Payments to influencers to promote your Amazon products.
- Affiliate Marketing: Commissions paid to affiliates driving sales to Amazon.
- Where to find: Respective platform ad dashboards, invoicing.
- Content and Creative Costs:
- Expenses for creating ad creatives (images, videos) for Amazon Ads or external campaigns.
- Fees for agencies managing your Amazon advertising or external marketing.
- Where to find: Agency invoices, internal cost tracking.
Example of Acquisition Costs Table:
| Cost Category | Example Sub-Categories | Source of Data |
|---|---|---|
| Amazon Ad Spend | Sponsored Products, Sponsored Brands, Sponsored Display | Amazon Advertising Console Reports |
| Promotions & Discounts | Coupons redeemed, Deal costs | Amazon Seller Central Reports |
| External Marketing | Google Ads, Social Media Ads, Influencer Campaigns | External Ad Platforms, Agency Invoices |
| Creative & Agency Fees | Ad creatives, Copywriting, Agency retainers | Internal Records, Agency Invoices |
2. Counting New Customers Acquired
This is often the most challenging part for Amazon sellers, as Amazon's direct "new customer" data can be limited depending on your seller status.
- For Brand-Registered Sellers (Recommended Method):
- New-to-Brand (NTB) Metrics: If you are a brand-registered seller and run Amazon Ads (Sponsored Brands, Sponsored Display, Amazon DSP), Amazon provides "New-to-Brand" metrics within your advertising reports. This metric indicates the number of first-time purchases of your brand's products on Amazon within a 12-month look-back window. This is the most accurate way to track new customers directly attributable to your Amazon advertising efforts.
- How to find: Navigate to your Amazon Advertising reports, specifically for Sponsored Brands or Sponsored Display campaigns. Look for the "New-to-Brand Orders" or similar columns.
- For Non-Brand-Registered Sellers or General Sales:
- Order Analysis: You'll need to manually analyze your order history or use a third-party analytics tool that integrates with Amazon. Filter your orders to identify customers who have made their first purchase from your specific ASIN or brand within a defined period. This can be complex, especially if customers buy multiple products or return after a long time.
- Estimation based on Campaign Goals: If a specific campaign (e.g., a heavily discounted promotion for a new product launch) is primarily aimed at attracting new users, you might estimate the number of new customers based on the total units sold during that campaign, assuming a high percentage are new. This method is less precise.
Practical Steps to Calculate CAC on Amazon
- Define Your Time Period: Choose a specific timeframe for your calculation (e.g., a month, a quarter). This ensures you're comparing costs and customers over the same duration.
- Sum All Acquisition Costs: Gather all your Amazon Ad spend, promotional costs, and external marketing expenses for the defined period.
- Example:
- Amazon Ads: $1,500
- Promotions (net cost to you): $300
- Facebook Ads driving to Amazon: $500
- Agency Fee (allocated to acquisition): $200
- Total Acquisition Costs = $2,500
- Example:
- Count New Customers Acquired:
- If Brand Registered: Use the "New-to-Brand Orders" metric from your Amazon Advertising reports for the same period.
- If Not Brand Registered: Estimate or track first-time buyers for your products through order analysis.
- Example:
- New-to-Brand Orders (from Amazon Ads reports): 100
- Additional new customers (from external campaigns, estimated): 20
- Total New Customers Acquired = 120
- Calculate CAC: Divide total acquisition costs by the number of new customers.
- Example:
- CAC = $2,500 / 120 = $20.83

Analyzing and Optimizing Your CAC
Once you have your CAC, use it to:
- Evaluate Campaign Performance: Compare the CAC of different advertising campaigns or channels to identify what's most efficient.
- Set Marketing Budgets: Inform future spending decisions by understanding how much it costs to acquire a customer.
- Improve Profitability: If your CAC is too high relative to your Average Order Value (AOV) and customer Lifetime Value (LTV), you might need to:
- Optimize your Amazon advertising campaigns (keywords, bids, ad copy).
- Improve product listings to increase conversion rates.
- Rethink your promotional strategies.
- Target more relevant audiences.
By regularly calculating and analyzing your CAC, Amazon sellers can make data-driven decisions to grow their business more profitably on the platform.
