What came from saving, and what came from returns?

Cumulative contributions are compared with investment growth. Negative growth is possible.

The next dollar has a jobCash first, then equities

The simulation began with $0. Contributions filled a six-month emergency reserve of $11,416 first. The reserve tracks historical CPI; once funded, every additional contribution went to Bucket 3’s monthly rebalanced 60% U.S. / 40% international equity mix. Cash stayed in Bucket 1 and earned the historical cash return.

Crude on purposeConsistent enough to compare starting lines

Income

Each selected year uses BLS series LEU0252888500: median usual weekly earnings for full-time wage-and-salary workers ages 25–34. That one starting income then rises 3% after every 12 months; later observed wage medians are intentionally ignored.

Expenses

The emergency reserve uses the 2023–2024 BLS Consumer Expenditure Survey mean for a one-person consumer unit age 25–34, excluding cash contributions and personal insurance/pensions. CPI backcasts that modern spending profile to the selected month.

Returns

Monthly cash, equity, and CPI history comes from the EarlyRetirementNow SWR Toolbox. Contributions happen at month-end, so each deposit begins earning returns in the following month. Taxes, fees, employer matches, and promotions are omitted.

Read this as a starting-line comparison, not a biography. It compares repeated rules against different historical markets. It does not follow the same people over time, model regional taxes or living costs, or claim that the expense benchmark describes every worker in that year.
