Customer Acquisition Cost in 2026, Channel by Channel

Paid Search: Still the Highest-Volume Channel, and Still Climbing

Search remains the largest paid-acquisition channel by volume, and its price kept rising through the past year. Across 16,446 US search campaigns tracked from April 2024 through March 2025, the average cost per lead on Google Search ads was $70.11, with an average cost per click of $5.26 and an average conversion rate of 7.52%¹. Year over year, cost per lead rose in 57% of the 23 industries studied (average +5.13%) and cost per click rose in 87% of industries (average +12.88%)¹. The spread between industries is wide: legal services carried the highest CPL at $131.63, while automotive repair and parts sat at the low end at $28.50¹.

Blended across all channels, HubSpot's compiled 2025 benchmarks (drawing on Market Research Future data) put average B2B cost per lead at $84¹³. Once a lead becomes a real prospect, conversion rates vary sharply by source: email leads convert to sales-qualified status 46% of the time, SEO-sourced leads 51%, webinar leads 30%, PPC leads 26%, and event leads 24%¹³.

Paid Social: Cheaper Leads, but Costs Rising Faster Than Search

Facebook's Lead-objective ads produced a lower average cost per lead than Google Search — $27.66 across 726 US campaigns in the year ending June 30, 2025 — but that figure was up 20.94% from $22.87 the year before, a faster rate of increase than search saw². Traffic-objective campaigns moved the opposite direction: average cost per click fell 6.67% to $0.70 across 554 campaigns, even as the average conversion rate for Leads campaigns slipped from 8.67% to 7.72%². As on search, industry spread is wide — dentists and dental services paid the most per lead on Facebook at $76.71, while restaurants and food paid as little as $3.16².

B2B advertisers on LinkedIn saw a steeper climb. Across more than 70 B2B SaaS companies with $5 million to $1 billion in annual recurring revenue and a combined $28 million in tracked ad spend, average cost per click rose from $10.48 in the first quarter of 2025 to $15.72 in the third quarter — a 1.5x increase in two quarters, measured under a disclosed position-based attribution model⁹.

At platform scale, Triple Whale's analysis of more than 33,000 ecommerce brands and $18.4 billion in tracked 2025 ad spend found Meta held 68.3% of ad spend share despite rising costs, with a median cost per acquisition of $38.17¹⁴. Amazon, by contrast, delivered the lowest cost-per-acquisition among major platforms in the same analysis — its CPA fell 5.65% to $13.35 and conversion rate ran 11.02%, even though Amazon's own cost per thousand impressions surged 47.46% to $7.82 over the same period¹⁴.

Customer Acquisition Cost by Industry and Business Model

Full customer acquisition cost — not just cost per lead or click — varies enormously by industry and by whether the buyer is a business or a consumer. First Page Sage's 2026 benchmark report, covering 29 industries, put average B2B CAC as low as $84 for ecommerce and as high as $1,424 for higher education and college recruiting³. On the B2C side, the same report found CAC ranging from $68 (ecommerce) to $708 (aviation)³. Narrowed to channel-level B2B benchmarks, the report found average CAC of $647 for SEO, $510 for email, and $658 for social media³.

A separate First Page Sage report, built from disclosed client data spanning January 2022 through August 2025, broke down combined organic-plus-paid B2B CAC by industry: $86 for ecommerce, $239 for B2B SaaS, $281 for construction, $791 for real estate, and $1,143 for education⁴. That report also found organic acquisition is consistently cheaper than paid within the same industry — real estate's organic CAC ran $660 versus $1,185 for inorganic acquisition⁴. Notably, the report disclosed that it excludes email, in-person events, direct mail, and outdoor advertising due to insufficient data — a methodology caveat that, if anything, strengthens confidence in the figures it does report⁴.

For B2B SaaS specifically, Benchmarkit's 2025 Performance Metrics Report found blended customer acquisition cost has risen 10% since 2022¹⁰. The same report flagged a complicating factor: expansion revenue (upsells and renewals from existing customers) now makes up 40% of total new annual recurring revenue industry-wide, and more than 50% for companies above $50 million in ARR — a mix that can mask the true cost of winning a brand-new customer when CAC is reported as a single blended number¹⁰.

Ecommerce: a Rising Average, and a Wide Spread Around It

Ecommerce CAC has its own well-documented history. Citing SimplicityDX's original research, HubSpot notes the average cost to acquire an ecommerce customer rose from $9 in 2014 to $29 in 2022, a 222% increase over eight years⁵. SimplicityDX's own release, published in mid-2022, put the underlying numbers this way: merchants lost $9 per new customer acquired in 2013 and $29 in 2022, with acquisition costs estimated to have risen roughly 60% in just the five years leading up to that report⁶. The same release found the offsetting good news: average profit per repeat sale rose from $28 to $39 over the same period, a 36% increase — meaning the economics of a second purchase improved even as the cost of a first one worsened⁶.

More recent data suggests the average has kept climbing but also kept spreading out. Shopify, citing Polar Analytics data, put average ecommerce CAC at $41.83 as of April 2026, alongside Meta ad CPMs that rose 8.64% year over year in 2025 per Triple Whale benchmark data⁷. Polar Analytics' own 2026 benchmark dashboard, however, reports a materially higher figure: a median CAC of $156 across ecommerce brands and a mean average of $242 — with consumer electronics running a median CAC of just $46.25 against a median new-customer order value of $135.60 and 5.16x return on ad spend¹⁵. The gap between these figures underscores how sensitive "average CAC" is to which brands, channels, and time windows a given benchmark actually samples.

Individual merchant results vary accordingly. Shopify documents Pura cutting CAC by up to 20% using its Audiences and Shop Campaigns tools together, and Duradry cutting CAC 29% over seven months using Shopify Collabs with more than 250 creators⁷. On the email side, Klaviyo's analysis of more than 183,000 customer accounts found flow-based (automated) emails deliver 3x higher click rates than one-off campaigns — 5.58% versus 1.69% — and generate about 41% of total email revenue from just 5.3% of total sends⁸. Nearly 48% of flow-driven email revenue comes from new buyers, compared with roughly 16% for one-off campaigns, making automated email one of the more efficient acquisition-adjacent channels in the data set⁸.

The Multi-Year Trend: Costs Rising Faster Than Budgets

Zooming out from any single channel, the multi-year direction is consistent even when the exact size of the increase differs by data set. Paddle's ProfitWell research, analyzing nearly 700 subscription companies, found both B2B and B2C customer acquisition costs up roughly 60% compared with five years earlier; within that figure, B2B CAC in established industries rose 70-75%, while niche B2C segments such as specialized ecommerce and technical media rose a comparatively modest 25-30%¹². That data is from 2020, but it lines up with the direction SimplicityDX and Benchmarkit both found in more recent, independent samples⁶,¹⁰.

Budgets have not kept pace. Gartner's 2025 CMO Spend Survey, based on 402 CMOs and marketing leaders surveyed across North America, the UK, and Europe, found marketing budgets held flat at 7.7% of overall company revenue in 2025 — unchanged from 2024¹¹. Paid media accounted for 30.6% of that budget, equal to 2.4% of company revenue, and 59% of CMOs said they lacked sufficient budget to execute their 2025 strategy — though that share had actually improved five percentage points from the year before¹¹. Rising per-lead and per-click costs against a flat budget share is, arithmetically, a shrinking volume of paid reach per dollar.

Deloitte Digital's 2025 Marketing Investment Trends survey of 1,395 US marketing leaders points to part of why budgets may be slow to adapt: 61% of marketing budgets are still set based on prior-period spend or enterprise-level revenue targets, rather than channel-level performance data¹⁶. The same survey found organizations that invest more in marketing technology than in working media — ads, events, sponsorships — saw an 18% greater sales lift from marketing and 7% greater overall revenue growth¹⁶, a data point suggesting that measurement and targeting infrastructure, not raw ad spend, is where some of the return on a flat budget is actually coming from.

Why Retention Keeps Showing Up in the Acquisition Conversation

Against rising acquisition costs, several sources in this data set point to the same offsetting lever: keeping the customers a business already has. HubSpot's synthesis of acquisition-cost research puts the multiplier plainly — it costs 5 to 25 times more to acquire a new customer than to retain an existing one⁵. The foundational research behind that framing traces back to Bain & Company's published account of Frederick Reichheld and Earl Sasser's Harvard Business Review study, which documented that a 5% increase in customer retention grew profits by 60% by the fifth year in Bain's MBNA credit-card case study¹⁷. The research frames this as a compounding effect over time, not a one-time gain: as customer loyalty improves, Bain notes that "market share and revenues go up, and the cost of acquiring and serving customers goes down"¹⁷.

That framing helps explain a pattern visible throughout this data set: channels with built-in retention mechanics — automated email flows to existing subscribers⁸, organic search and SEO⁴, Shopify's repeat-purchase tooling⁷ — consistently show lower or more stable acquisition-adjacent costs than pure paid-media channels, even as paid CPCs and CPLs climb across almost every platform measured here.
