What Is a Good CAC for Ecommerce? 2026 Benchmarks
First-hand guidance from the Daymark team on analytics workflows, growth reporting, and the operational metrics teams use to make decisions.
Add up the customer acquisition cost each ad platform reports and the total usually implies you acquired more customers than actually placed an order. That's not a broken pixel. It's what happens when Meta, Google, and email marketing each claim credit for the same buyer. A good blended CAC for most ecommerce brands runs $22-45, while paid-channel CAC alone typically runs $68-84, and neither number means anything without knowing lifetime value.
This guide covers the gap between blended and channel-reported CAC, directional benchmarks by vertical, and why "good CAC" is really a question about LTV wearing a different name.
Blended CAC vs. Channel-Reported CAC
Blended CAC is total marketing spend, across every channel, divided by every new customer acquired in the same period, paid and unpaid. Channel CAC is one platform's spend divided by the customers that platform's own tracking claims credit for.
The two disagree because of overlapping attribution. When a customer sees a Meta ad, later searches your brand name on Google, then clicks an email before buying, all three channels can independently claim that one conversion. Sum the channel-reported CACs and you've effectively divided total spend by more "customers" than you actually acquired, which makes each channel look artificially efficient.
The gap can be large. One analysis found platform-reported CAC coming in at $52 against a real blended CAC of $178, a 3.4x difference on the exact number a team would use to set next month's budget, per AdBeacon. Returning customers you didn't pay to reacquire quietly subsidize the blended number too, so even blended CAC needs to isolate new customers specifically, not just total orders.
Good CAC by Vertical
CAC varies more by category than almost any other acquisition metric, largely because it tracks competition for attention and average order value.
| Vertical | Directional CAC | Note |
|---|---|---|
| Beauty | ~$90-130 | High competition, strong repeat potential offsets cost |
| Apparel | ~$90-120 | Crowded paid social auctions |
| Electronics | ~$100-377+ | Wide range, high price point tolerates higher CAC |
| Food & beverage | ~$53-100 | Lower price point, needs volume to work |
| Pet care | ~$68-90 | Lower competition than beauty or apparel |
Ranges are drawn from Mobiloud's and Eightx's 2026 CAC data. Blended, paid-channel CAC across categories averages $68-84, up sharply from five years earlier as iOS tracking changes and rising CPCs have pushed acquisition costs higher industry-wide, per Mobiloud.
Why CAC Is Meaningless Without LTV
A rising CAC is only a problem if lifetime value isn't rising with it. A brand that spends $60 to acquire a customer worth $180 over their lifetime is in far better shape than a brand spending $30 to acquire a customer worth $45, even though the second brand's CAC looks better in isolation.
The number that actually tells you whether acquisition is working is the ratio between the two. A LTV:CAC ratio of 3:1 to 5:1 is generally healthy for D2C brands. Below 2:1, you're paying more to acquire a customer than they'll return in value, and growth is quietly unprofitable no matter how the CAC number reads on its own. Above 5:1, you're likely underspending relative to what your margins could support.
How to Get Your Real Blended CAC
Pull total marketing spend across every channel for a given period, then divide by the count of genuinely new customers Shopify recorded in that same period, not the sum of "new customers" each ad platform separately claims. That single change fixes the double-counting problem, because Shopify only records one order per customer regardless of how many channels touched them along the way.
Once you have a trustworthy blended CAC, pair it with LTV calculated over a realistic window, 90 days or your typical repeat purchase cycle, whichever is longer. The blended CAC calculator and LTV:CAC calculator both work from your actual spend and order data rather than platform-reported figures.
Frequently Asked Questions
What is a good CAC for ecommerce?
A good blended CAC for most ecommerce brands runs $22 to $45, though paid-channel CAC alone often runs $68 to $84. The right number depends heavily on average order value and category, since a $100 CAC is fine for a high-AOV electronics brand and unworkable for a low-AOV food and beverage brand. CAC only means something next to LTV.
Why is my blended CAC higher than what each ad platform reports?
Each ad platform claims credit independently when a customer touches multiple channels before buying, so summing channel-reported CAC divides spend by more claimed customers than actually exist. Blended CAC, calculated from total spend divided by genuinely new Shopify customers, avoids that double count and is typically higher and more accurate than any single platform's number.
What is a good LTV to CAC ratio?
A ratio of 3:1 to 5:1 is generally considered healthy for ecommerce. Below 2:1, a customer's lifetime value doesn't sufficiently exceed what it cost to acquire them, meaning growth is likely unprofitable. Above 5:1 often signals under-investment in acquisition relative to what margins could support, leaving profitable growth on the table.
Does CAC vary a lot by product category?
Yes. Beauty and apparel often run $90 to $130 due to crowded paid social auctions, while food and beverage runs lower at $53 to $100 given lower price points. Electronics can run anywhere from $100 to over $377 because higher order values tolerate a higher acquisition cost. Always compare CAC to the category's typical order value, not in isolation.
Why has ecommerce CAC risen so much in recent years?
Blended, paid-channel CAC has climbed sharply, driven mainly by iOS privacy changes that degraded ad tracking accuracy and by rising cost-per-click as more brands compete for the same auctions. The result is that a dollar of ad spend now buys meaningfully fewer new customers than it did several years ago across nearly every ecommerce category.
Conclusion
Stop reading CAC as a standalone score. Fix the double-counting problem by calculating blended CAC from total spend against genuinely new Shopify customers, compare it to your vertical's typical order value, and then check it against LTV before deciding whether it's actually good.
