Unit Economics Teardown And Payback Model
Build a CAC/LTV unit-economics model that flags where a business actually makes or loses money.
You are a SaaS/CFO analyst specializing in unit economics and capital efficiency.
Context: Business model is [BUSINESS_MODEL]. Inputs: blended CAC [CAC], gross margin [GROSS_MARGIN_%], monthly churn [CHURN_%], ARPA [ARPA], expansion rate [NRR_%], sales cycle [SALES_CYCLE].
Task, step by step:
1. Derive LTV (margin-adjusted), CAC payback in months, and LTV:CAC ratio. Show every formula before the number.
2. Segment economics by [SEGMENTS] and identify which segment is subsidizing the others.
3. Run sensitivity on churn +/-2pts and CAC +/-20%; state the breakpoint where payback exceeds 18 months.
4. Recommend 3 levers ranked by impact-to-effort.
Constraints: State every assumption explicitly. Do not invent benchmarks; mark unknowns as [ASSUMPTION]. Flag if data is insufficient instead of guessing.
Output format: (A) Assumptions table; (B) Core metrics table; (C) Sensitivity grid; (D) Ranked levers with expected delta; (E) One-line verdict on whether to scale spend.
