How much does 400,000 euros earn per month in France?

Updated 28 July 2026

In France, €400,000 invested earns between €867 and €3,000 per month depending on the investment option chosen: around 2.6% per year in a life insurance euro fund, 4 to 6% in rental property, 7 to 9% on average in equities or ETFs, with a risk of capital loss. This article compares the potential monthly income by type of investment (regulated savings accounts, the stock market, ETFs, property, SCPIs, a French non-listed real-estate investment fund comparable to a REIT).

Key takeaways

• No return is guaranteed outside regulated savings accounts: the income from an investment in equities, ETFs, property or SCPIs moves with the markets.
• The Livret A pays 1.5% net until 31 July 2026, then 1.7% from 1 August 2026, up to a cap of €22,950.
• Compound interest sharply increases the capital over the long term when gains are reinvested rather than spent.
• Taxation (the flat tax on interest and capital gains) and inflation reduce the net return actually received each month.
• Spreading the money across several investment options divides the risk of capital loss, without guaranteeing a high return.

Why is it so hard to know how much €400,000 earns per month?

There is no single figure: the income depends on the type of investment, on its performance (not guaranteed outside regulated savings accounts), on the term, on taxation and on inflation.

Uncertain performance of investments without a guarantee

Working out how much €400,000 earns per month is difficult because of the uncertain performance of investments without a guarantee. Investments differ in profitability and in volatility, which means the gains are not stable. Diversification can help reduce that uncertainty, but it does not guarantee a high return.

Risks of the different investments

The level of risk taken and the risk of capital loss vary from one investment to another. A low-risk investment might offer a more stable but lower return, while a high-risk investment might offer higher but less certain return potential. Understanding the risks attached to each investment is crucial to assessing the potential profitability of €400,000 invested.

How gains compound

The mechanics of interest compounding also influence how profitable an investment is. Compound interest builds up on the capital invested, raising its value over time. Variations in the rate of return can greatly affect the final amount, which makes long-term gains hard to estimate. To help gauge that effect, a compound interest calculator can be useful.

Taxation by type of investment

How profitable an investment turns out to be is also driven by taxation. Different types of investment can be subject to different tax rates, such as the flat tax or specific tax allowances. A thorough understanding of the applicable tax rates is needed to estimate accurately how much €400,000 earns per month.

Factoring inflation into the calculations

Finally, it is essential to account for rising inflation when calculating the gains on an investment. Inflation erodes the value of money over time, which can shrink the income an investment provides. It is therefore important to use real rates of return, adjusted for inflation, to estimate the profitability of €400,000 invested.

How much does €400,000 earn by type of investment?

Depending on the investment option chosen, €400,000 can generate anything from a few hundred euros per month through cautious holdings (regulated savings accounts, euro funds) to more than €2,000 per month through equities or ETFs with a higher expected return, at the cost of a risk of capital loss.

How much can €400,000 earn on the stock market?

Investing on the stock market can deliver attractive performance, but that depends on the shares picked and on the market. The profitability of shares varies and carries risk, which means the return is not guaranteed. To keep a better grip on that risk, it is advisable to diversify the portfolio across shares from different sectors and companies.

Assuming a hypothetical annual return of 7% (illustrative, not guaranteed), €400,000 invested on the stock market could generate a monthly income of around €2,333. It is important to note, however, that performance and profitability are not constant and depend on market swings.

€400,000 in an S&P 500 ETF (hypothetical return 10% (illustrative, not guaranteed))

€400,000 in a World ETF (hypothetical return 8% (illustrative, not guaranteed))

The rates shown in these tables (7%, 8%, 10%) are simulation assumptions based on the average historical returns of equity markets (MSCI World, +8.1% per year over 1990-2025); they are not a guarantee of future performance.

How much can €400,000 earn in property?

Investing in rental property is a popular option for those looking to generate a regular income. The rental yield depends on several factors such as the purchase price, the location, rental demand and management fees.

As an example, assuming a gross rental yield of 4%, a €400,000 property could generate around €1,333 gross per month, before charges, tax and rental voids. It is essential, however, to factor in taxes, maintenance charges and any management fees to assess the net return.

€400,000 in SCPIs (hypothetical return 5% (illustrative, not guaranteed))

SCPIs (Sociétés Civiles de Placement Immobilier) allow you to invest in rental property on a pooled basis, without managing anything directly. Their return is not guaranteed and the capital is not protected.

How much can €400,000 earn in regulated savings accounts?

French regulated savings accounts are products whose capital is protected by a State guarantee (within the regulatory caps) that let you save at a generally low interest rate. You cannot, however, deposit €400,000 into a single savings account, because each one has its own cap. The sum therefore has to be spread across several accounts.

Among the regulated savings accounts, the Livret A pays 1.5% net (since 1 February 2026), rising to 1.7% on 1 August 2026, up to a cap of €22,950 (see Livret A: rate and cap). The Livret de développement durable et solidaire (LDDS) also has a cap of €12,000, with an interest rate identical to that of the Livret A.

Frequently asked questions

Is €400,000 enough to live off the income?

It depends on the standard of living targeted. At a net return of 3 to 4%, €400,000 generates around €1,000 to €1,330 per month, often not enough on its own to cover a household's spending, but useful alongside other income.

Should everything go into regulated savings accounts?

No. Regulated savings accounts are capped (€22,950 for the Livret A, €12,000 for the LDDS) and their return stays low. For €400,000, you need to combine several investment options according to your time horizon and your risk tolerance.

How much wealth is needed to generate passive income?

To generate passive income, you need enough wealth to produce regular, stable income. That income depends on the type of investments made, on their return and on the amount invested. The standard of living sought, along with everyday and unexpected spending, must also be taken into account.
There is no single answer, because every situation is different. Diversified investment strategies suited to your needs can nonetheless help you get there.

Where should you invest €400,000?‍

There are many ways to invest €400,000. Each option has its advantages and drawbacks in terms of profitability, risk and liquidity.
Savings accounts offer a low return, but high safety and high liquidity.
Bonds are fixed-income investments carrying relatively low risk. You can invest in government or corporate bonds, depending on your risk profile.
Shares represent ownership stakes in companies. They offer high return potential, but also carry greater risks.
Property can generate regular rental income and appreciate over the long term. It does, however, require active management and comes with maintenance costs.
Alternative investments, such as art, start-ups or crypto-assets (regulated in Europe by the MiCA regulation, Markets in Crypto-Assets), can offer a high return, but also carry a higher level of risk.
It is important to review your financial objectives, your risk profile and your investment horizon before making a decision. Diversification is a widely recognised approach to reducing risk and improving returns.

What tax applies to the income from €400,000 invested?

It varies by investment option: interest and capital gains on most financial investments are subject to the flat tax, while regulated savings accounts are exempt from income tax and social security contributions. The wrapper chosen changes the net return substantially.

How can you limit the risk when investing €400,000?

Diversification is the most widely recognised approach: spreading the sum across several asset classes (regulated savings accounts, bonds, shares, property) reduces exposure to a single market. It limits the risk of capital loss without guaranteeing a high return.
