Where the numbers come from
- Real monthly prices for more than 12,000 US stocks and funds, updated nightly.
- US market returns since 1928, from NYU Stern.
- Median net worth by age, from the Federal Reserve's 2022 survey.
- Every result shows how it was worked out and what it assumes.
Trading
Have an Amaltash account? The trading plugin lets you run it from a
conversation with Claude. Describe a strategy in plain English, have Claude
backtest it, paper-trade it with $25,000 of simulated cash, add money from
your linked bank, and check balances. It needs sign-in. It can never withdraw
money. Withdrawals happen only in your Amaltash dashboard.
/plugin marketplace add amaltash-hq/mcp
/plugin install trading@amaltashThen run /mcp, pick amaltash, and choose Authenticate. Approve access
in the browser that opens. See the trading guide for
headless setup and more.
