Financial independence: how to get there sooner than you think

Imagine waking up on a Monday with no obligation to go to work. Not because you're sick or it's a holiday. But because you have enough money to live without depending on a salary.

Sounds like science fiction? To most people, it does. But more and more people are achieving it — many of them without extraordinary incomes.

It's called financial independence. And the path is simpler than you've been led to believe.

What the FIRE movement is

FIRE stands for Financial Independence, Retire Early. It originated in the US in the 1990s, was popularised by the book Your Money or Your Life, and today has active communities worldwide.

The core idea is simple: you accumulate assets that generate enough passive income to cover your expenses. From that point on, working becomes a choice — not a requirement.

The 4% rule — the maths behind FIRE

In 1998, an American study called the Trinity Study analysed decades of stock market data and concluded: if you withdraw 4% of your portfolio each year, the money lasts at least 30 years in the vast majority of historical scenarios.

This gives us a formula to calculate your "number" — the amount you need to have invested to be financially independent:

It sounds like a lot. But let's look at how long it actually takes to get there.

How long it takes — depends on one variable

The most important variable is not your salary. It's your savings rate — the percentage of your income you invest every month.

• If you save 10% of your income, it takes roughly 40 years.
• If you save 25%, it takes roughly 32 years.
• If you save 50%, it takes roughly 17 years.
• If you save 70%, it takes less than 9 years.

These estimates assume you invest in assets with a historical average return of 7% per year, adjusted for inflation.

The concrete path

Step 1: Know what you actually spend

You can't build a target number without knowing your real annual expenses — not what you think you spend, but what you actually spend. Track everything for 3 months and calculate the average.

Step 2: Widen the gap between what you earn and what you spend

You can do this from both sides: spend less and/or earn more. Both work, but spending less is more immediate. Start with the big categories — housing, car, subscriptions.

Step 3: Invest the difference automatically

Set up an automatic transfer on payday to your brokerage account. Buy global index ETFs monthly. Don't try to time the market.

Step 4: Don't stop, even when the market drops

When the market falls 20%, most people stop investing or sell. Those who reach financial independence do the opposite — they buy more, because it's cheaper.

The FIRE myths that put people off

Myth 1: "I have to stop working"

You don't. The goal of FIRE isn't to stop working — it's to have the freedom to choose. Many people reach financial independence and keep working because they love what they do. The difference is they no longer have to.

Myth 2: "It's only for high earners"

Someone on an average income who saves 30% and invests consistently for 20 years can be financially independent. Someone earning twice as much but saving 5% never will be.

Myth 3: "I have to live like a monk"

You can live well while building wealth. The secret is being intentional — spending on the things that genuinely give you satisfaction and cutting the rest.

A real example

Maria is 32, earns €1,800 net per month, and decides to save and invest €500 monthly (28% of her income). With an average return of 7% per year, in 20 years she'll have approximately €260,000. With monthly expenses of €1,300 (€15,600 annually), her number is €390,000. With a few more years or a slight reduction in expenses, Maria can retire at 55.

She doesn't need to be rich. She needs to be consistent.

Where to start today

Calculate your number. Multiply your annual expenses by 25. Don't be frightened by the result — most people are. The goal right now is simply to understand the distance.

Then increase your savings rate by 1% this month. Just 1%. And invest that difference.

Financial freedom starts with a single transfer.
