Numbers are the start, not the story. The simulator takes your after-tax figure and lets you allocate it — real properties, cars, boats and jets at market prices, investments with honest yields, family support, staff payroll — with a 30-year projection that shows whether your plan survives, and warns you the year it wouldn't.
