Is there a way to specify the % of income that is allocated to cash holdings vs. investments? The modeller seems to assume that I will keep all future income as cash, which seems unrealistic.
The way it currently works, the simulation uses income in a given year to cash-flow expenses for that year, and the rest is allocated according to the items you configure in the Financial Goals section. As a simple example, you could define a desired emergency fund of $20k as priority #1, then maximized taxable investments as priority #2... which would mean in any given year, money left over after expenses goes to (A) topping off the emergency fund if needed, then (B) to taxable investments. Does that help add some clarity?
