The Math of Early Retirement: FIRE Number and the 4% Rule最佳语录
Retirement isn't an age—it's a number. If you can save 50% or more of what you earn, you aren't just being frugal—you're fundamentally compressing decades of work into a few years.

Budgeting and getting to early retirement
常见问题
The Financial Independence, Retire Early (FIRE) movement is based on the idea that retirement is a specific financial number rather than a set age like sixty-five. By focusing on the math of your life, you can compress decades of work into a few years. The core strategy involves increasing your savings rate to 50% or more of your income, allowing you to buy back your time and achieve independence much earlier than traditional retirement models suggest.
Your FIRE Number is the total amount you need in your investment portfolio to sustain your lifestyle without working. To calculate it, take your annual expenses and multiply them by twenty-five. For example, if you spend fifty thousand dollars a year, your target number would be one point two-five million dollars. This calculation provides a baseline for the Financial Independence, Retire Early community to determine when they have reached their goal.
The 4% rule is a foundational principle used to ensure your investment portfolio lasts throughout retirement. It suggests that you can withdraw 4% of your total investments every year, adjusted for inflation, with a high probability that the money will not run out. This rule is the mathematical basis for the FIRE Number, helping individuals determine how much they need to save to support their annual expenses indefinitely through their investments.
In the math of early retirement, your savings rate is a more critical factor than your total income because it dictates how quickly you can reach financial independence. Saving 50% or more of what you earn allows you to fundamentally shorten your working years. While income is important, focusing on how much you keep rather than how much you earn is what enables the compression of a traditional forty-year career into a much shorter timeframe.
