CAC by Acquisition Channel
| Channel | Typical CAC Range | Characteristics |
|---|---|---|
| Inbound (Content/SEO) | Low ($200-2,000) | High volume, lower intent, longer sales cycle. Best for SMB. |
| Outbound (SDR-driven) | Medium-High ($3,000-15,000) | Targeted, higher intent. Scales linearly with headcount. |
| Paid (PPC/Social) | Medium ($1,000-8,000) | Scalable but competitive. CPA increases as you scale. |
| Referral/Word-of-mouth | Very Low ($100-500) | Highest quality but hard to scale intentionally. |
| Partner/Channel | Medium ($2,000-10,000) | Revenue share model. Efficient at scale but slow to build. |

Frequently Asked Questions
How do you calculate customer acquisition cost?
The simple formula is CAC = Total Sales & Marketing Spend / Number of New Customers Acquired. For a more accurate picture, use fully-loaded CAC which includes: marketing and sales salaries (including management allocation), paid advertising, content and SEO costs, events and sponsorships, sales tools and CRM subscriptions, commissions, and agency fees. Most companies undercount CAC by 30-40% by excluding headcount costs.
What is a good CAC for SaaS?
It depends entirely on your ACV (Annual Contract Value). A $5K ACV product should have $500-1,500 CAC. A $50K ACV product can tolerate $10K-25K CAC. Enterprise products at $200K+ ACV may see $50K-100K+ CAC and still be healthy. The absolute number matters less than the ratio to LTV (target 3:1+) and the payback period (target under 18 months for most stages).
What is the difference between blended CAC and paid CAC?
Blended CAC uses total S&M spend divided by all new customers, regardless of acquisition channel. Paid CAC only counts paid channel spend divided by customers acquired through paid channels. Blended CAC is the standard metric for investor reporting. Paid CAC helps you evaluate the efficiency of specific paid channels. The gap between them reveals how much your organic/inbound motion contributes. A large gap means organic is doing heavy lifting.
Should I include salaries in CAC?
Yes. Fully-loaded CAC includes all sales and marketing salaries, including management time allocation. This is the number investors expect to see. The common mistake is reporting only paid media spend as CAC, which dramatically understates the true cost. If you have 3 SDRs and 2 AEs, their fully-loaded compensation is part of CAC. Budget for sales tools, CRM licenses, and office space allocation too.
