The FIRE movement, for Financial Independence, Retire Early, aims for financial independence: having enough wealth for its income to cover your spending, without depending on a salary. The best-known benchmark, the 4% rule, says you need capital of about 25 times your annual spending: €600,000 to live on €2,000 a month. This guide, written for French tax residents, explains that calculation and its limits, what €50,000 or €100,000 really yields, how long it takes depending on your savings rate, and the French rules that weigh on someone living off their capital.
- 25 times annual spending: the target capital under the 4% rule, or €600,000 for €2,000 of spending a month.
- More cautious for very early retirement: a 3.5% withdrawal rate requires 28.6 times spending, €685,714 for €2,000 a month.
- The savings rate decides everything: on €3,000 net a month, about 40 years saving 20%, 23 years at 40%, 13 years at 60%.
- In France, someone with no earned income may owe a 6.5% health contribution on part of their capital income.
Living off your capital is no magic trick: it is a calculation between what you spend, what you save and what your investments earn. It does not promise wealth; it looks for the point where work becomes a choice.
This guide applies to French tax residents. The returns quoted are assumptions for illustration, not promises: an equity portfolio can fall several years in a row.
TL;DRFIRE aims for capital whose income covers your spending. The 4% rule gives capital of about 25 times annual spending, but it comes from 30 years of US data: for retirement at 40, a 3 to 3.5% withdrawal rate is more cautious. €100,000 yields only about €333 a month at 4%. The timeline depends mostly on the savings rate. In France, choosing the right wrappers (PEA, assurance vie) cuts tax on withdrawals, and a health contribution can apply without earned income.
What is FIRE?
FIRE is an approach born in the United States: save a high share of your income, invest it in a diversified, low-cost way, until your wealth lets you live off its income. Some stop working, others keep a chosen or part-time activity. Living off your capital means drawing on its income: dividends, interest, rent, or regular withdrawals from a portfolio.
The 4% rule and the capital you need
The 4% rule comes from William Bengen's work in 1994 and the so-called Trinity study in 1998: on US data, withdrawing 4% of the initial capital each year, adjusted for inflation, lasted at least 30 years in the vast majority of periods, with a portfolio mixing stocks and bonds. The target capital is your annual spending divided by the withdrawal rate.
| Monthly spending | Capital at 4% (25 times) | Capital at 3.5% |
|---|---|---|
| €1,500 | €450,000 | €514,286 |
| €2,000 | €600,000 | €685,714 |
| €3,000 | €900,000 | €1,028,571 |
Three limits to keep in mind: the data are American, over an exceptional century for US stocks; the horizon tested is 30 years, while retirement at 40 can last more than 50; and fees and taxes are not included. Hence the frequent choice of 3 to 3.5% for very early independence.
Living off €50,000 or €100,000
These often-searched amounts are not enough to live on. At 4%, €100,000 allows a withdrawal of €4,000 a year, about €333 a month before tax; €50,000, about €167 a month. That is a useful top-up, not a replacement income. A promise to draw much more, without risk, is the first sign of a scam.
How long does it take?
The timeline depends less on returns than on the savings rate, because saving more lowers both the target (you spend less) and the time to reach it (you put in more). Example with €3,000 net a month, an assumed real return of 4% a year and a target of 25 times spending:
| Savings rate | Saved per month | Target capital | Time |
|---|---|---|---|
| 20% | €600 | €720,000 | about 40 years |
| 40% | €1,200 | €540,000 | about 23 years |
| 60% | €1,800 | €360,000 | about 13 years |
Real return, after inflation, chosen for illustration. The compound interest calculator lets you redo the sum with your own numbers, and the 50/30/20 rule helps free up savings.
French wrappers for a FIRE plan
- PEA: after five years, withdrawals bear only 18.6% social charges on the gains portion, with no income tax, up to €150,000 of contributions. See our guide to the PEA.
- Assurance vie: after eight years, a yearly allowance of €4,600 of gains (€9,200 for a couple) on income tax, and favourable inheritance rules. See our guide to assurance vie.
- Securities account: no cap, but gains pay 31.4% in 2026. See the French securities account (CTO).
- Rental property: regular rents, but taxed at the progressive scale with 17.2% social charges, and management remains work.
What France adds: health cover, pension, tax
With no earned income, someone living off capital stays covered by French health insurance under the universal health protection scheme (PUMa), but may owe the cotisation subsidiaire maladie. According to the Urssaf, it is due when earned income is below 20% of the annual social security ceiling and capital income above 50% of that ceiling, set at €48,060 in 2026. It is 6.5% of the capital income above that threshold, reduced if you have some earned income. With €40,000 of capital income and no earned income, that is about €1,038 a year.
Stopping early also means contributing less to your pension: quarters and points stop with work, and the pension will be based on a short career. Our guide to the minimum pension in France shows what an incomplete career pays.
Risks not to underestimate
- Sequence of returns: a sharp market fall just after you stop working weighs far more than the same fall twenty years later.
- Inflation: it raises spending every year, and the capital has to keep up.
- Longevity: capital may need to last more than 50 years for independence at 40.
- Concentration: betting everything on a few securities or a single property exposes you to an accident. See portfolio diversification.
Frequently asked questions
What does FIRE stand for?
Financial Independence, Retire Early: reaching financial independence, wealth whose income covers your spending, so you can stop working early or work by choice.
How much do you need to live off your capital?
Under the 4% rule, about 25 times annual spending: €600,000 for €2,000 a month. For very early retirement, a 3.5% withdrawal rate requires about €686,000.
Can you live off €100,000?
No, not in the sense of living off the income: at 4%, €100,000 yields about €333 a month before tax. It is a supplementary income.
What is the 4% rule?
A benchmark from US data: withdrawing 4% of capital in the first year, then the same amount adjusted for inflation, lasted at least 30 years in the vast majority of past periods.
How long does it take to reach financial independence?
Mostly a matter of savings rate: with a 4% real return, about 40 years saving 20% of income, 23 years at 40%, 13 years at 60%.
Does someone living off capital pay contributions in France?
They may owe the 6.5% cotisation subsidiaire maladie if earned income is below 20% of the social security ceiling and capital income above 50% of it, on the part above that threshold.
