Super cool simulator

Build scenarios from steps placed at chosen months, add company grants, and compare how each plan changes net worth, diversified assets, the most concentrated asset, debt, and taxes over time.

Same for all scenarios

To see what a single step does, press “+ New scenario” above the graphs, then add or change one step; the new scenario follows as you type. To change a scenario later, click its name above the graphs and edit it in the left bar. The box on each scenario shows or hides it. Changes on Starting position and Settings apply to every scenario. Results depend heavily on the return of the most concentrated asset, so try several values. Retirement accounts count toward the diversified goal. A limit that blocks sales of the most concentrated asset still allows selling other taxable holdings and borrowing for the home. Borrowing to invest uses its own separate loan, because the securities-backed loan can't buy securities. Net worth doesn't subtract tax on gains that haven't been sold yet. The table shows the tax owed if everything were sold, and the net worth after it, so plans that sell can be compared with plans that don't on equal terms. Tax uses the flat rates from Settings; state tax, tax brackets, the mortgage-interest deduction and step-up in basis are not modelled.
