Unit Economics Analyzer

Break down your business to the numbers that actually matter. This skill calculates and benchmarks your unit economics — CAC, LTV, payback period, contribution margin — so you know exactly which customers make you money and which ones burn it.

What It Does

When activated, the agent will:

1. Calculate Core Metrics

   • Customer Acquisition Cost (CAC) — fully loaded (ads + sales salaries + tools + overhead)
   • Lifetime Value (LTV) — using both simple and DCF methods
   • LTV:CAC Ratio — the single number investors care about most
   • CAC Payback Period — months to recover acquisition spend
   • Contribution Margin — per unit and per customer

2. Benchmark Against Industry

   Metric	Healthy SaaS	Marketplace	E-commerce	Services
   LTV:CAC	3:1 – 5:1	2:1 – 4:1	1.5:1 – 3:1	4:1 – 8:1
   CAC Payback	12-18 mo	6-12 mo	1-3 mo	3-6 mo
   Gross Margin	70-85%	40-65%	30-50%	50-70%
   Net Revenue Retention	110-130%	100-115%	80-100%	90-110%

3. Segment Analysis

   • Break unit economics by customer segment, channel, plan tier, geography
   • Identify which segments are profitable and which are subsidized
   • Flag "toxic" segments where CAC > LTV

4. Cohort Decay Modeling

   • Month-over-month retention curves by acquisition cohort
   • Revenue decay rate and true LTV (not the optimistic version)
   • Churn-adjusted LTV using: LTV = ARPU × Gross Margin / Monthly Churn Rate

5. Scenario Planning

   • What happens to payback if CAC increases 20%?
   • Impact of 5% churn reduction on LTV
   • Break-even analysis: minimum retention rate for profitability
   • Pricing sensitivity: how price changes flow through to unit economics

How to Use

Tell the agent:

• "Analyze my unit economics" — walks through full calculation
• "My CAC is $X and monthly churn is Y%" — gets specific benchmarks
• "Compare my SaaS unit economics to benchmarks" — industry comparison
• "Model what happens if we cut churn by 3%" — scenario analysis
• "Break down unit economics by customer segment" — segmentation

Required Inputs

Provide what you have (the agent will estimate what's missing):

Revenue side:

• Average Revenue Per User (ARPU) — monthly or annual
• Gross margin percentage
• Monthly or annual churn rate
• Expansion revenue rate (upsells, cross-sells)

Cost side:

• Total sales & marketing spend (monthly/quarterly)
• New customers acquired in same period
• Customer success/support costs per account
• Onboarding costs per customer

Formulas Reference

CAC = Total Sales & Marketing Spend / New Customers Acquired

LTV (Simple) = ARPU × Gross Margin% / Monthly Churn Rate

LTV (DCF) = Σ (Monthly Revenue × Gross Margin%) / (1 + Discount Rate)^month

LTV:CAC Ratio = LTV / CAC  [Target: >3:1]

Payback Period = CAC / (ARPU × Gross Margin%)  [months]

Contribution Margin = (Revenue - Variable Costs) / Revenue

Magic Number = Net New ARR / Prior Quarter S&M Spend  [Target: >0.75]

Burn Multiple = Net Burn / Net New ARR  [Target: <2x]

Red Flags Dashboard

Signal	Threshold	Action
LTV:CAC below 1:1	Losing money on every customer	Stop acquiring, fix retention or pricing
LTV:CAC below 3:1	Unsustainable at scale	Reduce CAC or increase retention
Payback > 24 months	Cash flow risk	Accelerate monetization or cut acquisition
Gross margin < 50%	Service business, not software	Re-examine delivery costs
Net retention < 100%	Revenue shrinking without new sales	Fix product-market fit
CAC trending up > 15% QoQ	Channel saturation	Diversify acquisition channels
Magic Number < 0.5	Inefficient growth spend	Pause scaling, optimize

Output Format

The agent produces:

• Executive Summary — 3-line verdict on business health
• Metrics Table — all calculated values with industry benchmarks
• Segment Breakdown — if data provided, per-segment P&L
• Scenario Matrix — sensitivity analysis on key variables
• Action Items — prioritized list of improvements with expected impact
