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)

1. Kill underperforming channels — Bottom 20% of channels by CAC efficiency → pause immediately
2. Tighten ICP targeting — Narrow ad audiences to best-fit segments (often cuts CAC 20-40%)
3. Optimize landing pages — A/B test headlines, CTAs, form length (10-30% conversion lift)
4. Activate referral program — Existing customers are your cheapest channel ($150-$600 vs $2K+ outbound)
5. Fix lead scoring — Sales time on bad leads = wasted CAC. Score ruthlessly.

Medium-Term (90 days)

6. Build content moat — SEO compounds. Every ranking page reduces future CAC
7. Automate nurture sequences — Drip campaigns convert leads without sales time
8. Partner channel deals — Revenue share with complementary products
9. Product-led growth hooks — Free tier, trials, freemium → organic conversion
10. Retargeting optimization — 70% cheaper than cold acquisition

Strategic (6+ months)

12. Community — User communities generate organic referrals
13. Product virality — Built-in sharing, team invites, network effects
