Customer Acquisition Cost (CAC) Optimizer
Analyze, benchmark, and reduce your customer acquisition cost across every channel.
What This Does
- Calculates true CAC (fully loaded — not just ad spend)
- Breaks down CAC by channel, segment, and cohort
- Benchmarks against industry standards
- Identifies the cheapest acquisition paths
- Models payback period and LTV:CAC ratio
- Generates a CAC reduction roadmap
How to Use
Tell your agent:
- "Calculate our CAC for last quarter"
- "Break down acquisition cost by channel"
- "What's our LTV:CAC ratio?"
- "Build a plan to cut CAC by 30%"
CAC Calculation Framework
True CAC Formula (Fully Loaded)
CAC = (Sales Costs + Marketing Costs + Overhead Allocation) / New Customers Acquired
Include:
- Ad spend (paid search, social, display)
- Content production costs
- Sales team comp (base + commission + benefits)
- Marketing team comp
- Tools & software (CRM, analytics, ad platforms)
- Agency/contractor fees
- Event/sponsorship costs
- Allocated overhead (office, IT, management time)
Exclude:
- Customer success / retention costs (that's your retention CAC)
- Product development
- General admin not tied to acquisition

CAC Reduction Playbook
Quick Wins (30 days)
- Kill underperforming channels — Bottom 20% of channels by CAC efficiency → pause immediately
- Tighten ICP targeting — Narrow ad audiences to best-fit segments (often cuts CAC 20-40%)
- Optimize landing pages — A/B test headlines, CTAs, form length (10-30% conversion lift)
- Activate referral program — Existing customers are your cheapest channel ($150-$600 vs $2K+ outbound)
- Fix lead scoring — Sales time on bad leads = wasted CAC. Score ruthlessly.
Medium-Term (90 days)
- Build content moat — SEO compounds. Every ranking page reduces future CAC
- Automate nurture sequences — Drip campaigns convert leads without sales time
- Partner channel deals — Revenue share with complementary products
- Product-led growth hooks — Free tier, trials, freemium → organic conversion
- Retargeting optimization — 70% cheaper than cold acquisition
Strategic (6+ months)
- Brand building — Strong brand = lower CAC across every channel
- Community — User communities generate organic referrals
- Product virality — Built-in sharing, team invites, network effects
