How is acquisition cost moving per channel?
№ 164 · CAC by channel trend
Definition
MetricFully loaded customer acquisition cost per channel, tracked period over period
Unitcurrency per acquired customer
Lines plot blended cost per acquisition over time, one per channel. Rising CAC across the board signals saturation; single-channel rise signals competitive bidding. Build per-channel: spend divided by new customers per period. Example: Meta CAC $24 to $42 (75% YoY increase, competitive saturation).
- CAC
- Customer acquisition cost. Fully loaded sales and marketing spend in a period divided by new customers won in that period.
- YoY
- Year on year. This period compared with the same period twelve months earlier.
Benchmarks
| Bottom 30% | Median | Top 30% |
|---|---|---|
| Outbound sales approx. $1,980, fintech and insurance $1,280 to $1,450, with paid channels inflating 15%+ year on year | B2B paid search approx. $802, LinkedIn approx. $982, B2B SaaS organic $205 against inorganic $341; consumer Google Ads CPA $70.11 | Organic and referral channels holding flat or declining year on year; B2B organic CAC in the $150 to $300 band, referral near $150 |
B2B services and SaaS client datasets covering January 2022 to August 2025, US-weighted, with organic defined as SEO plus organic social and inorganic as PPC/SEM plus paid social; consumer CPA figures from Google Ads campaign panels for 2025 · The largest public channel-level CAC dataset is First Page Sage, which is an agency client panel rather than a platform dataset, so it skews to companies that buy marketing services and to US mid-market. Absolute values should be treated as ordering rather than as levels. CAC definition varies sharply between sources: some divide media spend by new customers, others include fully loaded salary and tooling, which moves the same channel by 2x or more. Phoenix Strategy Group's 40 to 60% CAC inflation from 2023 to 2025 is an aggregate claim not tied to a single panel, so read it as direction, not magnitude.
| Category | Bottom 30% | Median | Top 30% |
|---|---|---|---|
| B2B, organic search and thought leadership | above $1,800 | $647 to $1,786 depending on whether content is thought-leadership led or basic SEO | under $600 |
| B2B, paid search | above $1,100 | $802 | under $650 |
| B2B, LinkedIn Ads | above $1,400 | $982 | under $750 |
| B2B, account-based marketing | above $6,000 | $4,664 | under $3,500 |
| B2C, paid social | above $320 | $230 | under $180 |
| B2C, paid search | above $400 | $290 | under $220 |
When it looks bad
Every channel line slopes up in parallel while the organic line rises fastest, which means the cheap channel has stopped compounding and paid is being used to backfill volume it used to supply for free.
Organic CAC moves from $210 to $340 over four quarters while paid search goes $760 to $910 and paid social $290 to $420, with total new customers flat, so the whole mix inflated roughly 40% for the same output.
What to do about it
- Separate auction inflation from efficiency loss by charting CPM alongside CAC per channel; if CPM rose and conversion rate held, the problem is the auction and the answer is mix, whereas if CPM held and conversion fell, the problem is creative or landing page and the answer is inside the channel.
- Rebalance toward organic where the gap is structural rather than cyclical; the First Page Sage panel shows paid CAC exceeding organic in 26 of 27 B2B industries, with IT and managed services at $325 organic against $840 paid, a 61% discount that persists across the 2022 to 2025 window.
- Watch the blended CPL convergence signal; in cybersecurity organic and paid CPL sit within 2% of each other at $404 and $411, which indicates a saturated category where incremental organic investment will not undercut paid and the honest move is to compete on conversion rather than on cost (HubSpot 2025 CPL and CAC benchmarks).
- Rebuild the denominator once per year with fully loaded cost including salary, agency and tooling; median B2B SaaS spends $2.00 in S&M per $1 of new ARR and most of that is people, so a media-only CAC trend will show improvement while the real cost per customer is rising.
