Average CAC by Ecommerce Industry: 2026 Vertical Benchmarks

The average CAC by ecommerce industry in 2026 ranges from about $23 for pet products to $110+ for beauty, with most direct-to-consumer verticals landing between $40 and $100. Customer acquisition cost (CAC) is the total sales and marketing spend required to win one new customer — and what counts as “good” depends entirely on your vertical’s margins and repeat-purchase behavior. A $90 CAC is alarming for a low-margin commodity but perfectly healthy for a beauty brand whose customers reorder every six weeks.

Below is the full 2026 benchmark table, the forces pushing these numbers up, and the one ratio that tells you whether your CAC is actually a problem.

What Is the Average CAC by Ecommerce Industry in 2026?

Average CAC by ecommerce industry spans a wide band, and the spread itself is the most useful insight. Beauty and apparel sit at the top because they compete in saturated paid-social auctions, while pet and other high-repeat categories sit far lower. Use the table as a directional benchmark, not a target — your real number depends on channel mix and contribution margin.

Ecommerce vertical	Typical CAC (2026)	Why it lands here
Beauty & personal care	~$110	Saturated paid social, heavy creative competition
Apparel & fashion	~$90	High ad costs offset by frequent reorders
Supplements	~$89	Subscription-friendly, strong LTV supports spend
Food & beverage	~$75	Thin margins force tight efficiency
Pet products	~$23	High repeat rate, loyal customers, lower competition

These figures align with vertical benchmarks reporting beauty near $110 and apparel near $90, and with broader ecommerce datasets showing acquisition costs ranging from roughly $50 to $377 depending on category and channel. Treat any single number as a midpoint with a wide distribution around it.

Why Is Ecommerce CAC So Different Across Verticals?

CAC diverges by industry because acquisition economics are downstream of margin, repeat behavior, and auction competition. Categories where customers buy often — pet food, supplements, consumables — can spend efficiently because each customer’s lifetime value is high and predictable. Categories with one-off or considered purchases, or with crowded ad auctions, pay a premium for every click.

Three structural factors explain most of the gap. Auction density determines how many brands bid against you for the same impression. Margin sets how much you can profitably pay. And purchase frequency decides whether a high CAC is recovered in one order or twenty. Beauty checks every “expensive” box; pet checks every “efficient” one.

How Much Has CAC Increased Recently?

Ecommerce CAC has risen roughly 40% between 2023 and 2026, and the climb shows no sign of reversing. Datasets tracking acquisition costs over this window report a ~40% increase driven by competition, privacy rules, and attribution loss, with some categories seeing even steeper jumps in paid-search costs.

The drivers are interlocking. iOS privacy changes degraded targeting and made conversions harder to attribute, so platforms optimize less precisely and brands compensate with more spend. More merchants chasing the same Meta, Google, and TikTok inventory pushes auction prices up. And as organic reach declined, paid became non-optional — concentrating demand into a handful of expensive channels. The net effect: rising costs across nearly every vertical, regardless of size.

When acquisition costs climb across the board, the winners aren’t the brands that spend less — they’re the ones whose customers come back often enough to make the spend pay off. — Adapted from First Page Sage, 2026 CAC benchmark analysis

Is a High CAC Actually a Problem? Watch LTV:CAC

A high CAC is only a problem relative to lifetime value, so the number to watch is the LTV:CAC ratio. The widely cited benchmark is at least 3:1 — customers should return three times their acquisition cost over their lifetime. A beauty brand paying $110 to acquire a customer who spends $400 over two years (3.6:1) is far healthier than a gadget seller paying $40 for a one-time $90 buyer (2.25:1).

This is why benchmark tables can mislead. The “expensive” verticals — beauty, supplements, pet — also have the highest repeat rates, so elevated CAC is sustainable. Before you panic about your number, calculate your ratio. You can model it quickly with a customer acquisition cost calculator, then compare against the typical CAC ranges for your category.

How to Lower CAC Without Cutting Spend

The most durable way to lower effective CAC is to raise lifetime value and acquire through lower-cost channels, not simply to spend less on ads. Brands that lean on referral, community, and group-buying mechanics consistently report lower blended acquisition costs because each new customer brings others in at near-zero marginal cost — referral-driven channels post some of the lowest CAC of any acquisition method.

Group buying is a clear example: when shoppers unlock a deal by inviting friends, the buyer becomes the acquisition channel, spreading cost across a group rather than a single paid click. For verticals stuck in expensive paid-social auctions — beauty and apparel especially — shifting even 10–20% of acquisition to social and referral mechanics can meaningfully bend blended CAC down. That’s the core idea behind Farabiulder’s approach to group-buying growth.

The takeaway: benchmark your CAC against your vertical, judge it against your LTV, and treat the average as a starting line — not a verdict.
