What is a parameter scan?

A parameter scan compares several versions of your financial scenario. You choose an existing input and a series of values to test. MRA runs TIME MACHINE for each value and includes a separate run of your current, unmodified scenario for comparison.

For example, if you have an annual expense called Living expenses, you could compare that expense at $48,000, $50,000 and $52,000. The scan shows the projected cash flow, spending, taxes and legacy for each version. Other expenses do not change just because this one is being scanned.

You choose the tested values. A parameter scan does not generate random market returns. It answers a question about how your plan changes when the selected assumptions change.
