FIRE Movement FAQ
Answers to the most frequently asked questions about achieving financial independence in the UK.
FIRE stands for Financial Independence, Retire Early. It is a personal finance movement focused on extreme savings and investment rates to allow individuals to retire decades earlier than traditional retirement ages, typically relying on the 4% safe withdrawal rule.
Your FIRE number is typically calculated by multiplying your expected annual retirement expenses by 25. This is derived from the ‘4% Rule’, which suggests you can safely withdraw 4% of your investment portfolio in the first year of retirement, adjusting for inflation thereafter, without running out of money.
While the average UK savings rate is around 5-10%, achieving FIRE typically requires a savings rate of 25% to 50% or more of your gross income. A 50% savings rate can theoretically lead to financial independence in about 17 years, assuming a 7% annual investment return.
Lean FIRE involves living on a minimalist budget (e.g., under £20,000/year) to retire as quickly as possible. Regular FIRE targets a comfortable middle-class lifestyle (e.g., £30,000–£40,000/year). Fat FIRE is for those who want to retire early without sacrificing a luxurious lifestyle, requiring a much larger portfolio (e.g., £60,000+/year in expenses).
