Frequently asked questions
Average SaaS CAC is approximately $205 for SMB-focused products and $1,000–$5,000+ for enterprise. The wide range reflects ACV differences — higher ACV products justify higher acquisition spend. The more important metric is LTV:CAC ratio, which should be at least 3:1 regardless of the absolute CAC number.
For SaaS, marketing ROI is typically measured through LTV:CAC ratio (target: 3:1+) and CAC payback period (target: under 12 months) rather than a simple revenue:spend ratio, because the revenue from a SaaS customer arrives over months or years. A 3:1 LTV:CAC means the customer returns 3× their acquisition cost over their lifetime.
Content and SEO consistently delivers the highest ROI for SaaS over a 24–36 month window because organic traffic compounds and has near-zero marginal cost at scale. Paid search delivers immediate results but requires continuous investment. Product-led growth (free trial to paid conversion) often delivers the lowest effective CAC because the product does the selling.
