runway-calculator
Calculate cash runway, burn, and the zero-cash date — and whether you're default alive or dead. Use when asked to work out runway, monthly burn, when the money runs out, or how much to raise/cut to reach a target. Produces a computed runway summary (net burn, months of runway, zero-cash date, default alive/dead) plus what it takes to extend it.

# Runway Calculator Skill For any company spending more than it makes, one number governs everything: how many months of cash are left. This skill computes net burn, runway, and the zero-cash date from your cash and P&L, judges whether you're **default alive or dead** (Paul Graham's test — would you reach profitability on current cash at current growth?), and shows the raise-or-cut needed to hit a target runway. ## Required Inputs Ask for these only if they aren't already provided: - **Cash in bank** (today). - **Monthly revenue** and **monthly expenses** (or net monthly burn directly). - **Monthly growth rate** of revenue, if you want the default-alive check. - **Target** — a runway you want to reach (e.g. 18 months) or a raise you're considering. ## Output Format ### Runway: [company] **1. The numbers** (computed via the helper): | Metric | Value | |---|---| | Net monthly burn | | | Cash in bank | | | **Runway (months)** | | | **Zero-cash date** | | | Default alive? | yes / no | **2. Default alive or dead** — on current cash and growth, do you reach profitability before the cash runs out? State it plainly; it's the question investors ask first. **3. To extend it** — the concrete

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.
