The number changed the question
For years, retirement was something I could imagine but not measure. I knew I wanted more freedom, more control over my time and less dependence on a salary. What I did not have was a number that connected the life I wanted to the money I needed.
The 25× rule
The calculation is simple: take the amount you expect to spend in one year and multiply it by 25. If your annual spending is €40,000, the framework produces a target of €1 million. If you spend €60,000, the number becomes €1.5 million. The calculation does not tell you what you will actually need. It gives you a starting point for thinking about financial independence.
Why spending matters more than salary
This changed the way I thought about retirement. A salary tells you what comes in. Spending tells you what the portfolio eventually has to replace. Someone earning €100,000 and spending €90,000 has a very different independence problem from someone earning €70,000 and spending €40,000.
The 4% idea behind the calculation
The 25× rule is closely associated with the idea of withdrawing roughly 4% of a portfolio in the first year of retirement, with adjustments over time. That is a planning framework based on historical market research, not a guarantee that a portfolio will support a particular lifestyle. Taxes, fees, asset allocation, market returns and the length of retirement all matter.
The number is useful because it makes trade-offs visible
Once there is a target, ordinary decisions look different. Saving another €500 a month is no longer just saving €500. It is another step toward a defined amount of invested capital. Spending another €500 a month also has a second meaning: it can increase the portfolio you need to reach financial independence.
Freedom was never really the number
The strange part is that the number is not the destination. The number is a way of buying clarity. I do not want a million euros because a million is magical. I want enough invested capital that the choices I make about my mornings are increasingly mine.
The number is not the destination. It is a way of buying clarity about what financial freedom could look like.
