Frequently Asked Questions
What is the FIRE movement?
FIRE stands for Financial Independence, Retire Early. It is a lifestyle movement focused on aggressive saving and investing so you can stop working for money well before the traditional retirement age. The goal is to accumulate enough assets that your investment returns cover your living expenses.
What is the difference between Lean, Regular, and Fat FIRE?
Lean FIRE targets a frugal retirement with minimal expenses. Regular FIRE aims to replace your current spending. Fat FIRE plans for a more luxurious retirement with higher annual spending. Each approach changes the savings target you need to reach.
How accurate is this calculator?
The calculator provides a solid estimate based on compound growth projections, but real-world returns vary year to year. Use it as a planning guide and revisit your numbers periodically to stay on track.
What is the 4% rule?
The 4% rule is a guideline suggesting you can withdraw 4% of your portfolio each year in retirement without running out of money over a 30-year period. This calculator uses that principle to estimate your FIRE number — the total savings needed to cover your annual expenses.
Is my financial data stored anywhere?
No. All calculations run entirely in your browser. Nothing is sent to any server, so your income, expenses, and savings information remains completely private.
