Frequently Asked Questions
The Rule of 25 is a quick way to find your FIRE number. Multiply your annual expenses by 25. This is the inverse of the 4% Rule. If you need $40k/year, you need $1M invested ($40,000 x 25 = $1,000,000).
For a traditional 30-year retirement, yes. For 40+ year retirements starting in your 30s, many experts recommend a 3.25% or 3.5% withdrawal rate to account for longer timelines.
Generally no. Unless you plan to sell your home and invest the proceeds, it doesn’t produce income to pay for groceries. Only include liquid, income-producing assets.
It is the risk of a market crash occurring just as you start withdrawing. A bad start can drain your portfolio before it has a chance to recover. This is why "Cash Buffers" are vital in early retirement.
Yes. FIRE is driven by your Savings Rate, not just your absolute income. Someone earning $50k and saving $25k has the same FIRE timeline as someone earning $500k and saving $250k.
In the US, many retirees use the Affordable Care Act (ACA) with subsidies, or relocate to countries with lower costs (Geo-Arbitrage).
FI is the point where you don’t NEED to work. Retirement is the CHOICE to stop working. Many "retired" FIRE members still earn income from hobbies or passion projects.
Always use "Real Returns" (Nominal minus Inflation). Our calculator does this for you to ensure your FIRE number is calculated in today's purchasing power.
A psychological trap where a person who has hit their FIRE number keeps working out of fear of market crashes or lack of identity outside of work.
Never. Our tool runs locally in your browser. We do not store, track, or share your net worth, income, or retirement plans.
