What it does
Unit Economics is an agent skill from mohitagw15856/pm-claude-skills. 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.
Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/unit_econ.py`).
It sits in Business, Finance & HR, covering Financial modeling. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked to calculate unit economics
- Work out LTV:CAC
- Find the payback period
- Check whether a business model is viable per customer
Example prompts
- “/unit-economics”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Unit Economics loads about 844 tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 381 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- description
- 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 (LTV:CAC ≥ 3, payback < 12 months).
3. Biggest levers — which input, improved realistically, moves the model most (usually churn or CAC), with the rough effect.
4. Caveats — where the inputs are assumptions vs. measured, and what to validate before betting on this.
Programmatic Helper
scripts/unit_econ.py (stdlib only) computes the model so the numbers are calculated, not estimated:
# in.json: {"arpa": 50, "gross_margin": 0.8, "monthly_churn": 0.03, "cac": 400}
python3 scripts/unit_econ.py in.json
python3 scripts/unit_econ.py in.json --jsonShow full SKILL.md (166 more words)Show less
Quality Checks
- LTV uses gross margin, not raw revenue (a common, model-breaking error)
- The numbers are computed by the helper, not eyeballed
- Verdict is stated against the standard benchmarks (LTV:CAC ≥ 3, payback < 12mo)
- The biggest lever is identified with its rough effect
- Assumed inputs are flagged separately from measured ones
Anti-Patterns
- Do not compute LTV on revenue instead of gross margin — it inflates LTV and hides an unviable model
- Do not ignore payback — a great LTV:CAC with a 30-month payback can still starve a business of cash
- Do not treat blended CAC as paid CAC — separate organic from paid or the model lies
- Do not present assumptions as facts — label estimated churn/CAC and validate them
- Do not optimise the smallest lever — model which input actually moves the outcome
Based On
SaaS unit-economics practice (David Skok / for Entrepreneurs) — margin-based LTV, LTV:CAC ≥ 3, payback < 12 months.
Example Trigger Phrases
- "Calculate unit economics."
- "Work out LTV:CAC."
- "Find the payback period."
- "Check whether a business model is viable per customer."
