All figures in today's dollars (real); the return dial is REAL. σ = 15% volatility, seed 42; N = 5,000 paths at rest. Withdrawals shown before taxes (taxes are not yet modeled). Social Security and pension offsets applied in retirement. Inflation is used for display conversion only. A required return is a description of the arithmetic, not a target to pursue.
