Living Standard Monte Carlo (aka, Full Risk Investing) is available in Premium and Professional versions of MaxiFi. It allows you to see how much risk your otherwise safe base plan is exposed to because of your asset allocation and investment strategies. Unlike traditional Monte Carlo in most planning software, it builds living standard and discretionary spending trajectories based on your plan instead of simply seeing if your retirement account dollars will last given your static spending levels.
