Individual skill
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.
