Field notes
The workflow models a household through separate income entries, contribution limits, employer matching, account types, Social Security, pensions, and spending. Its backtest compares each plan with historical start years from 1871 onward, while a separate Monte Carlo view samples 1,000 random runs in five-year blocks. The page says calculations remain in the browser and that tax inputs use 2026 federal, payroll, and state tables.
