roi-estimator
Estimate the ROI, payback, and NPV of an investment, project, or purchase. Use when asked to calculate ROI, build a business case, justify a purchase/initiative, work out payback period, or compare options by return. Produces a computed ROI summary (net benefit, ROI %, payback, simple NPV) with the assumptions made explicit and a sensitivity note, so a business case is defensible.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# ROI Estimator Skill Every "should we spend on this?" decision needs a defensible number. This skill estimates the return — ROI %, payback period, and a simple NPV that accounts for the time value of money — from costs and expected benefits, with the assumptions stated and a sensitivity check, so a business case survives the first sceptical question instead of collapsing. ## Required Inputs Ask for these only if they aren't already provided: - **Costs** — upfront cost, and any ongoing/recurring cost (per period). - **Benefits** — the expected gain per period (revenue uplift, cost saved, time saved × loaded rate). Quantify; if it's an estimate, say so. - **Time horizon** — over how many periods to evaluate (e.g. 3 years). - **Discount rate** — for NPV (default ~10%); state it. ## Output Format ### ROI: [investment] **1. The numbers** (via the helper): | Metric | Value | |---|---| | Total cost (over horizon) | | | Total benefit (over horizon) | | | Net benefit | | | **ROI %** | | | **Payback period** | | | Simple NPV (@ discount rate) | | **2. The verdict** — worth it / marginal / no, in one line, and against what bar (e.g. beats the discount-rate hurdle, payback within tolerance).

What does the roi-estimator skill do?
Estimate the ROI, payback, and NPV of an investment, project, or purchase. Use when asked to calculate ROI, build a business case, justify a purchase/initiative, work out payback period, or compare options by return. Produces a computed ROI summary (net benefit, ROI %, payback, simple NPV) with the assumptions made explicit and a sensitivity note, so a business case is defensible.
How do I install it?
Run `npx skills add mohitagw15856/pm-claude-skills --skill roi-estimator --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.
