unit-economics
Model the unit economics of a business — CAC, LTV, payback, contribution margin — from real inputs. Use when asked to calculate unit economics, work out LTV:CAC, find the payback period, or check whether a business model is viable per customer. Produces a computed unit-economics summary (LTV, CAC, ratio, payback, contribution margin) with a verdict and the levers that move it most.

# Unit Economics Skill A business is only viable if each customer is worth more than it costs to acquire and serve. This skill computes the core unit economics — CAC, LTV, the LTV:CAC ratio, payback period, and contribution margin — from real numbers (not vibes), states a clear verdict against the rule-of-thumb benchmarks, and shows which lever moves the model most. ## Required Inputs Ask for these only if they aren't already provided: - **ARPA** — average revenue per account, per month (or per period). - **Gross margin %** — the share of revenue left after cost-to-serve. - **Churn %** — monthly customer (or revenue) churn — drives LTV. - **CAC** — fully-loaded cost to acquire a customer (sales + marketing ÷ new customers). ## Output Format ### Unit Economics: [business] **1. The numbers** — computed, with the formula shown (use the helper script so they're consistent): | Metric | Value | Benchmark | |---|---|---| | Lifetime (1/churn) | | | | LTV (ARPA × margin ÷ churn) | | | | CAC | | | | **LTV : CAC** | | ≥ 3:1 healthy | | **Payback (months)** | | < 12 healthy | | Contribution margin | | | **2. Verdict** — healthy / borderline / underwater, in one line, against the benchmarks (LT

What does the unit-economics skill do?

How do I install it?
Run `npx skills add mohitagw15856/pm-claude-skills --skill unit-economics --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mohitagw15856/pm-claude-skills, a repository with 1,255 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
