Financial independence

As explained in Investing for Programmers

Financial independence is a state in which a person can meet essential living expenses without depending on employment income.

Financial independence means covering essential living expenses without depending on employment income. It can begin when passive income covers some expenses and grow until work becomes optional or more fulfilling rather than necessary. section 1.0

Two practical routes lead toward financial independence:

  • Accumulate enough reserves to fund living expenses for the remainder of life. section 5.4
  • Build passive income that covers annual expenses; estimate the required capital by dividing yearly costs by the expected return rate. section 5.4

A cautious estimate

A 5% return assumption implies required capital equal to annual expenses divided by 0.05. Treat the result as a rough estimate: inflation, spending changes, and an appropriate safety margin can make the target higher. section 5.4

Growth assets may outperform fixed-income investments over long periods, but projected returns cannot pay current bills and may decline sharply. Patience, diversification, and a strategy suited to personal circumstances matter more than universal formulas. section 5.4

How Investing for Programmers covers it

How deep it goes
Defines two routes and supplies a capital estimate while stopping short of a complete inflation-adjusted retirement model.
Examples
Uses employment stress, annual-expense calculations, a 5% yield estimate, and comparisons involving VOO and URTH.
What you can do after
Evaluate a rough financial-independence target and compare passive-income strategies while accounting for inflation and downside risk.
How it connects
Links financial independence to passive income, inflation, compounding, growth portfolios, fixed-income investments, and behavioral finance.
