Question 1

What is a good CAC for SaaS?

Accepted Answer

There's no universal "good" CAC — it depends entirely on your LTV. The key metric is LTV:CAC ratio. SaaS businesses should target at least 3:1 (LTV 3× higher than CAC). If your LTV is $1,500 and CAC is $300, that's a healthy 5:1 ratio.

Question 2

What is included in CAC calculation?

Accepted Answer

CAC should include ALL sales & marketing costs: ad spend, marketing team salaries, sales team salaries, sales tools (CRM, outreach tools), marketing tools (SEMrush, HubSpot), events, and content production. Many companies undercount by excluding salaries.

Question 3

What is the difference between blended CAC and paid CAC?

Accepted Answer

Blended CAC divides all S&M costs by all new customers (organic + paid). Paid CAC divides only paid spend by customers from paid channels. Blended CAC is more realistic for unit economics. Paid CAC is useful for measuring channel efficiency.

Question 4

How do I reduce my CAC?

Accepted Answer

Top levers: (1) Content marketing and SEO — lowers blended CAC by adding organic customers, (2) Product-led growth — free trial or freemium removes sales cost, (3) Referral programs — $20–$50 referral bonuses vs $300 paid CAC, (4) Improve conversion rate — same spend, more customers.

Question 5

How long should it take to recoup CAC?

Accepted Answer

The "CAC payback period" should be under 12 months for most SaaS businesses. Enterprise SaaS can stretch to 18–24 months given higher LTV. If your payback period exceeds 18 months and you're not enterprise-focused, your unit economics need improvement.
