CAC Benchmarks
Typical Customer Acquisition Cost ranges by industry and channel, used to sanity-check whether your CAC sits in a healthy zone for your AOV and LTV.
CAC benchmarks are reference ranges for what online retailers typically pay to acquire one paying customer, broken out by vertical (apparel, beauty, electronics, home, supplements) and by acquisition channel (Meta, Google, TikTok, email, organic). They exist because a raw CAC number — €38, €92, €145 — means nothing in isolation. A €92 CAC is excellent for a €280 AOV mattress brand and catastrophic for a €22 AOV snack brand.
The tight rule most operators use: CAC should sit below LTV / 3. Anything above LTV / 1 is bleeding cash; anything below LTV / 5 usually means you're under-investing in growth. Benchmarks help you locate yourself on that spectrum before you change spend.
The numbers below are blended ballpark ranges for stores in the €1M–€15M revenue band, drawn from public industry reports and the patterns we see across Shopify, WooCommerce, and Magento accounts. Use them to locate yourself, not to set a target — your real benchmark is your own LTV.
Two numbers matter more than the table itself: your contribution-margin AOV (what's left after COGS, shipping, payment fees, returns) and your 12-month repeat LTV. Once you have those, every CAC figure on this page becomes either a green light or an alarm.
Blended CAC ranges by vertical (online retail, €1M–€15M revenue band)
| Vertical | Typical AOV | Median CAC | Healthy CAC range | Implied LTV target |
|---|---|---|---|---|
| Apparel & accessories | €65 | €32 | €22 – €45 | €90+ |
| Beauty & skincare | €48 | €28 | €18 – €40 | €85+ |
| Supplements & wellness | €55 | €34 | €24 – €48 | €105+ |
| Home & decor | €120 | €58 | €40 – €80 | €180+ |
| Consumer electronics | €185 | €72 | €50 – €105 | €220+ |
| Food & beverage (subscription) | €38 | €22 | €14 – €32 | €95+ |
Channel mix moves CAC more than vertical does. A beauty brand running 80% Meta prospecting will sit near the top of its range; the same brand with a strong email and organic-search engine will sit near the bottom. The chart below shows the spread we see by channel across the same revenue band.

How to read these numbers against your own funnel
Start by calculating blended CAC: total acquisition spend (ads + agency fees + tooling allocated to acquisition) divided by net new customers in the same window. Most stores get this wrong by counting returning buyers, which flatters CAC by 30–50%. Strip them out.
Then split it by channel using a last-click or data-driven attribution view in GA4. If your Meta CAC is €70 against a €42 channel median, the issue is rarely the channel — it's creative fatigue, audience saturation, or a landing-page conversion rate that's well under 2%. That's a CRO problem disguised as a media problem.
The 3:1 rule is a floor, not a target
LTV:CAC of 3:1 is the line below which the unit economics get nervous — not the goal. Best-in-class operators run at 4:1 to 5:1 on blended spend and only push toward 3:1 deliberately, when they're accepting thinner margin to capture market share. If you're sitting at 2:1 with no plan to fix it, you're funding growth from working capital.
What to do when your CAC is out of range
If you're above the healthy range, the fastest lever is almost never lowering ad spend — it's lifting on-site conversion rate. A 2.1% to 2.7% lift on the same traffic cuts blended CAC by ~22% with no media change. Pull a funnel report, find the step with the biggest drop-off (usually product page → add-to-cart or cart → checkout), and run a test there first.
If you're below the healthy range and growth has stalled, you're under-investing — there's room to push paid spend up until CAC approaches LTV/3. The trap here is scaling the same audiences and creatives that work today; CAC drifts up sharply once you exhaust your warmest cohorts. Plan creative and audience expansion before you raise the budget cap.
Frequently asked questions about CAC benchmarks
There's no single number — it depends on your AOV and 12-month LTV. The working rule is CAC below one-third of LTV. For a typical apparel store with €65 AOV and ~€95 LTV, a blended CAC of €22–€32 is healthy.
Track both. Blended CAC (all acquisition spend / all new customers) is your true unit-economics number and what investors care about. Paid CAC (paid spend / paid-attributed new customers) is what you optimise inside the ad platforms. They tell different stories and you need both.
Meta is mostly interruption / prospecting traffic — you're paying to create demand. Google Shopping and Search capture existing demand, so the people who click are further down the funnel and convert at higher rates. That's why blended Google CAC tends to run 30–50% below Meta for the same store.
Take all acquisition costs in a period (ad spend, agency fees, acquisition tooling, creator payments) and divide by the number of net new first-time customers in that same period. Exclude returning buyers, exclude organic referrals only if you're measuring paid CAC specifically, and use the period the cash actually went out — not the attribution window.
3:1 is the floor for healthy unit economics. 4:1 to 5:1 is where most profitable online retailers operate at scale. Below 3:1 you're squeezing margin; above 5:1 you're almost certainly leaving growth on the table by under-spending.
Directly. Your maximum sustainable CAC is roughly contribution-margin AOV × expected repeat purchases over 12–24 months, divided by 3. A €40 AOV at 30% contribution margin and 1.4 purchases per year gives you a CAC ceiling around €11–€16 — much lower than the headline AOV suggests.
First-purchase. CAC measures the cost to acquire a new customer once. The lifetime side of the equation is LTV, which you compare against CAC. Mixing the two collapses the ratio that tells you whether the business is healthy.
Monthly at minimum, weekly during peak season or when you're scaling spend. CAC drifts as audiences saturate and creative fatigues, and the lag between a CAC spike and the resulting cash-flow problem is usually 60–90 days — long enough to do real damage if you're checking quarterly.
The three usual causes: creative fatigue (CTR has dropped on your top ads), audience saturation (you're now buying colder traffic at the same budget), or a conversion-rate drop on-site (a site change, slower load times, or a broken tracking pixel). Diagnose in that order.
It distorts channel-level CAC by under-attributing conversions to Meta and over-attributing to direct and organic, which makes paid CAC look worse than it is. Blended CAC is unaffected because it doesn't rely on attribution. If your platform CAC and blended CAC have diverged sharply, attribution loss is the likely culprit.
