fire-number
Compute a financial-independence (FIRE) target and years-to-reach with every assumption labeled as an assumption — plus a sensitivity table instead of a single false-precision answer. Use when asked what's my FIRE number, when can I retire early, how much do I need to be financially independent, or model my savings trajectory. Produces the FIRE number, years-to-target at stated assumptions, a return × withdrawal-rate sensitivity grid, and the honest list of what the model ignores.

# FIRE Number Skill Every FIRE calculation is three assumptions wearing a number's clothing: a withdrawal rate, a real return, and the pretense that returns arrive in a convenient order. This skill does the math properly and refuses the false precision — the deliverable is a *surface* of outcomes with the assumptions labeled, not a single date to organize a life around. ## What This Skill Produces - **The FIRE number** — annual spend ÷ withdrawal rate, with the withdrawal rate named as the choice it is - **Years to target** — at stated savings, contributions, and real return - **The sensitivity grid** — years-to-target across return (3/5/7%) × withdrawal rate (3/3.5/4%) - **The ignored-risks list** — sequence-of-returns, taxes, spending drift — stated, not buried ## Required Inputs Ask for these if not provided: - **Current invested savings** (invested — not home equity, not emergency cash) - **Monthly contribution** (realistic, not aspirational — ask which) - **Target annual spend in retirement** (today's dollars; if unknown, current spend is the honest starting guess, labeled) - **Return and withdrawal assumptions** (defaults: 5% real, 4% withdrawal — both labeled as defaults) ##

What does the fire-number skill do?
Compute a financial-independence (FIRE) target and years-to-reach with every assumption labeled as an assumption — plus a sensitivity table instead of a single false-precision answer. Use when asked what's my FIRE number, when can I retire early, how much do I need to be financially independent, or model my savings trajectory.

How do I install it?
Run `npx skills add mohitagw15856/pm-claude-skills --skill fire-number --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.
