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.

Yes — Wisconsin taxes lottery winnings at 7.65% on top of the 37% federal top rate.
The annuity pays 30 growing checks (each +5%): about $5,889,995 after tax in year one, roughly $391,324,500 total over 30 years. The lump sum pays about $171,418,950 now — historically, disciplined investing of the lump sum can beat the annuity, but the annuity protects winners from themselves. Model both in the simulator.
