Lean FIRE (Financial Independence, Retire Early) refers to a lifestyle choice that emphasizes achieving financial independence with a minimalist approach to living expenses. It’s a subset of the broader FIRE movement, where individuals aim to retire early by maximizing their savings rate, often living frugally to do so.

Key Principles of Lean FIRE

  • Frugal Living: Keeping living expenses as low as possible, often well below the average for their income level or geographic area.
  • High Savings Rate: Aiming to save a significant portion of their income, often 50% or more.
  • Investing Wisely: Putting savings into investments that can grow over time and provide sustainable income in retirement.

How Lean FIRE Differs from Traditional FIRE

Lean FIRE differs from traditional FIRE in its intense focus on minimalism and lower spending. While traditional FIRE proponents might aim for a comfortable lifestyle in retirement, Lean FIRE adherents make do with less to achieve financial independence sooner.

Example of Lean FIRE in Action

Suppose Alex earns $50,000 per year and manages to live on just $20,000, saving $30,000 annually. By investing these savings wisely, Alex aims to retire much earlier than traditional retirement age, accepting a more modest lifestyle in retirement.

Considerations for Pursuing Lean FIRE

  • Lifestyle Choices: Lean FIRE requires significant lifestyle adjustments and a commitment to living below your means.
  • Financial Planning: Careful planning is crucial to ensure that the reduced savings can sustain long-term retirement needs.
