E-commerce CAC benchmarks show how much online stores spend to acquire a new customer. This page summarizes broad customer acquisition cost reference points, category differences and the mistakes that make CAC misleading.
Back to the hub: E-commerce Statistics.
This page belongs to the Customer Retention silo. For retention economics, compare it with
repeat purchase rate benchmarks,
LTV benchmarks,
CAC benchmarks,
LTV to CAC benchmarks,
churn rate benchmarks
and subscription share of revenue.
Use this page with LTV and LTV:CAC benchmarks before deciding whether acquisition spend is scalable.
Benchmarks
E-commerce CAC benchmark reference points
CAC is highly sensitive to category, margin, channel mix, creative quality, attribution method and whether repeat buyers are excluded from the numerator and denominator.
$68–$78
LoyaltyLion summarizes Shopify-style ecommerce CAC ballparks in the roughly $68–$78 range, while noting wide variation by country and industry.
~$78
UpCounting gives a directional average ecommerce CAC around $78 across categories.
$45–$250+
Eightx reports that ecommerce CAC can range from about $45 to $250+ depending on vertical, margin and channel mix.
| Benchmark | Directional level | Interpretation |
|---|---|---|
| Broad blended CAC | $68–$78 | Useful as a sanity check, not as a target for every store. |
| Lower-CAC categories | $45–$100 | Often replenishment, food and beverage, pet or lower-AOV products with clear demand. |
| Mid-range categories | $90–$130 | Fashion, beauty and lifestyle categories can sit here depending on creative and retention. |
| High-CAC categories | $175–$250+ | Luxury, electronics and high-consideration goods can support higher CAC if LTV and margin are strong. |
Segments
CAC ranges by ecommerce vertical
| Vertical | Typical CAC pattern | Why it differs |
|---|---|---|
| Food and beverage | Often lower to mid CAC | Impulse buying, replenishment and sampling can help acquisition if margin supports discounting. |
| Beauty and personal care | Mid CAC, strong repeat potential | High competition raises ad cost, but replenishment and loyalty can improve payback. |
| Fashion and apparel | Mid to high CAC | Creative fatigue, returns and discount dependency can make CAC harder to interpret. |
| Pet care | Often attractive if repeat is strong | Recurring demand and loyalty can support healthy LTV:CAC if churn is controlled. |
| Electronics and luxury | High absolute CAC | Higher AOV can justify higher CAC, but purchase frequency may be lower. |
Definitions
Blended CAC vs. channel CAC
| CAC type | Formula | Use case |
|---|---|---|
| Blended CAC | Total acquisition spend ÷ new customers acquired | Board-level and business model health. |
| Paid CAC | Paid media spend ÷ new customers from paid channels | Performance marketing analysis. |
| Fully loaded CAC | Acquisition spend + agency + tools + creative + team cost ÷ new customers | Finance and profitability planning. |
| Channel CAC | Channel-specific spend ÷ new customers attributed to that channel | Budget allocation and scaling decisions. |
Important: do not divide total ad spend by total orders unless you intentionally want customer acquisition plus retention orders blended together. CAC should normally use new customers, not all orders.
Usage
How to use CAC benchmarks
CAC is only useful when compared with payback, gross margin and customer lifetime value. A $200 CAC can be healthy for a high-LTV luxury or subscription cohort, while a $50 CAC can be unhealthy if gross margin and repeat purchases are weak.
| Decision | Compare CAC with | Signal |
|---|---|---|
| Should we scale spend? | Gross profit LTV and MER | Scale only if the cohort pays back inside a realistic cash window. |
| Is a channel efficient? | Channel CAC and new-customer rate | Low CPA can hide existing-customer retargeting. |
| Is acquisition becoming riskier? | CAC trend vs. repeat purchase and margin | Rising CAC is dangerous when retention does not improve. |
Methodology
Methodology note
CAC benchmarks should be read as directional ranges. Public benchmarks often combine different definitions: first-order CAC, blended CAC, paid CAC, channel CAC or fully loaded CAC. For internal benchmarking, define the numerator, denominator and attribution window before comparing against external sources.
Sources
Sources and notes
Use these sources as directional benchmarks. Retention economics should be normalized by category, margin, order frequency, subscription model, attribution window and customer cohort.
