How it works

Total = PV × (1+r)^n + PMT × [(1+r)^n − 1] / r. Real (inflation-adjusted) return ≈ nominal return − inflation rate. Tax drag reduces after-tax returns: a 7% nominal return in a 22% bracket yields ~5.5% after tax on gains. Index fund expense ratios of 0.03–0.10% vs. 1%+ for active funds compound significantly over decades. Sequence-of-returns risk matters most near retirement.
