Find the Earliest Age You Can Safely Retire with a Free Claude Money App
A free, open-source money app that runs on your own computer and your Claude sign-in. It plays out thousands of stock markets on your real savings and tells you the first age your money lasts 80% of the time
Most people have no idea when they can actually stop working. Open Net Worth is a free, open-source money app (AGPL, on GitHub) with an AI agent built in that can run on the Claude you already pay for. Give it your birth date, what you save each month and what you'd spend in retirement, and its Outlook plays out thousands of possible stock markets on your real net worth. Your safe-to-retire age is the earliest age where your money lasts in at least 80% of them.
Here's what it does, how to set it up with Claude, what to ask, and the catch.
What it does
- Safe-to-retire age: the earliest age with at least 80% odds your money lasts your whole life, plus your pot today.
- Thousands of markets, not one hopeful line: the chart shows the likely range of your net worth across your life.
- What-ifs in plain words: ask "what if markets fall 30%?", "retire at 55?" or "buy a house in 2028?" and the agent sets the levers and redraws the chart.
- Life events: drag a house, a new baby, tuition, an inheritance or a sabbatical onto the age it happens.
- Your whole money picture: every account in any currency, a zero-based or 50/30/20 budget, investments and gains.
- An agent that does the chores: it sorts and logs transactions, reconciles accounts and builds reports, and shows you a confirm card before it changes anything.
- Runs on your own computer: your book stays on your machine, with no telemetry.
