Educational tool — not tax or investment advice. Federal income tax only (no FICA, state, or AMT). Traditional 401k/IRA contributions reduce taxable income; Roth contributions do not. IRA deductibility not income-tested. IRS limits auto-indexed by CPI. Catch-up contributions applied after age 50. When income is zero or insufficient, pre-retirement spending is drawn from the portfolio.
