Understanding Deterministic Projections vs. Sequence-of-Returns Risk
This planner compounds working savings monthly and tests annual inflation-adjusted retirement withdrawals assuming a steady average return (reducing portfolio return by 2 percentage points during retirement to reflect a more conservative bond/cash allocation).
