Free FIRE calculator that models what generic ones skip: capital gains tax with exemptions, pensions locked until an access age, your mortgage, income that starts later. No signup. The whole scenario lives in the URL, so a shared plan is just a link.
Stocks, cash, funds, pension, property and crypto, plus the mortgage and loans, synced read-only into one honest net-worth number. Capital gains matched to your lots, a forecast to the month you could retire, and a database of your own behind it.
