How Much Does €300,000 Invested Earn per Month in France?

Updated on 29 July 2026

€300,000 invested in France earns between €650 and €2,250 per month depending on the vehicle: about 2.6% a year in a euro fund within life insurance, 4% to 6% in rental property, and 7% to 9% on average in stocks or ETFs, with a risk of capital loss. This guide breaks down returns by investment type.

When it comes to investing a substantial sum such as €300,000, understanding the range of investment options available and their potential returns is essential. Each type of investment, whether stocks, bonds, mutual funds or other investment vehicles, carries a distinct risk and return profile. The return on invested capital depends on market conditions, interest rates and the investment strategy chosen.

Beyond that, the tax implications are a significant factor to consider, since they can materially affect the net return on an investment. Taxation varies depending on the nature of the investment and the tax regime of the country concerned.

Key takeaways

• In the stock market (stocks, ETFs), €300,000 can target an indicative historical gross return of 5% to 7% a year, with no guarantee.
• In rental property or SCPI (a French non-listed real-estate investment fund, comparable to a REIT), the net return before tax is often between 2% and 6%, subject to vacancy, non-payment and illiquidity risk.
• Regulated savings accounts (Livret A, LDDS) pay 1.50%, a rate raised to 1.70% from 1 August 2026, but they remain capped (€22,950 and €12,000): they can only absorb part of a €300,000 capital.
• Income from financial investments has been subject to the flat tax (PFU) of 31.4% since 2026 (12.8% income tax and 18.6% social contributions).
• After 8 years, life insurance grants an annual tax allowance of €4,600 (€9,200 for a couple) on gains.
• Any investment in stocks, ETFs, real estate or unit-linked funds carries a risk of capital loss.

Why is it so hard to know how much €300,000 invested earns per month?

Working out the monthly return on €300,000 invested is complex, since it is shaped by several factors: market volatility, the range of investment products available, changes in taxation, and the impact of inflation on the real value of returns.

The fluctuation of returns on investments with no capital guarantee

Returns depend heavily on market volatility, which makes past performance an unreliable guide to future returns. Every type of investment carries a risk level that shapes its expected return, and riskier assets can potentially offer higher returns, with no guarantee.

The risks tied to different types of investment

Effective diversification is essential to managing a portfolio, since it spreads out risk. That said, every investment category, whether stocks, funds, bonds or others, has its own volatility and expected return, which makes it hard to estimate gains precisely.

The effect of taxation across different investment and account types

Both income tax on investment income and social contributions can significantly reduce net returns. The tax framework varies by product (life insurance, PEA (a French tax-advantaged equity savings account), and so on), which complicates the calculation of returns after tax.

Accounting for the effect of inflation in financial analysis

Rising inflation reduces the real value of returns. To understand its real impact on purchasing power, the real return must be calculated after accounting for changes in consumer prices, which adds another layer of complexity to financial analysis.

How much does €300,000 invested earn per month, by investment type?

Investing a capital of €300,000 can potentially generate significant income, whether through the stock market, real estate or savings products. Profitability varies depending on the type of investment, asset valuation, taxation and the investor's risk profile. Apps such as Finary make it possible to track the evolution of one's net worth over time and visualise how a capital sum could grow under different return scenarios.

How much can €300,000 invested earn per month in the stock market?

Investing €300,000 in the stock market offers the option of investing in stocks, ETFs (Exchange-Traded Funds) or bonds. With ETF investments, for example, an investor might expect an indicative average historical gross return of 5% to 7% a year, with no guarantee (based on historical stock-market data), subject to market fluctuations. It is essential to note, however, that the valuation of stocks and other listed products can vary, which affects the final return.

€300,000 in World ETFs (8% return assumption, not guaranteed)

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

How much can €300,000 invested earn per month in real estate?

As an asset class, real estate investment, particularly through rental property or pierre-papier via SCPI (Sociétés Civiles de Placement Immobilier), is a profitable option. With a €300,000 investment, the rental yield can range between 2% and 6% net of tax, subject to the risks of vacancy, non-payment and depreciation of the property. The rents collected generate an income stream, and the return can be enhanced over the long term through compound interest.

How much can €300,000 earn in regulated savings accounts?

These regulated savings accounts (Livret A, LDDS) are risk-free investments, guaranteed by the French state and available at any time, but their return is low and, above all, capped. They can therefore only absorb part of a €300,000 capital: the remaining balance must be directed to other vehicles (life insurance, the stock market, real estate).

• Livret A: a regulated rate, currently 1.50%, raised to 1.70% from 1 August 2026, capped at €22,950 in contributions.
• LDDS (Livret de Développement Durable et Solidaire): same rate as the Livret A, capped at €12,000.

For a single saver, the combined Livret A and LDDS therefore represent a maximum of €34,950. The table below shows what these accounts would earn once filled to the cap, at the 1.70% rate applicable from 1 August 2026.

Tax considerations and their impact on returns

When it comes to investing €300,000, it is essential to factor in the tax impact that shapes the net return. Both financial products and tax wrappers can vary considerably in how they are taxed.

First, tax on interest income can take the form of the flat tax, also known as the PFU (Prélèvement Forfaitaire Unique), at 31.4%, which includes 18.6% in social contributions and 12.8% in income tax (see Service-public.gouv.fr). According to Service-public.gouv.fr, the social-contributions rate on investment income rose to 18.6% from 1 January 2026. This option simplifies taxation and can be advantageous if savings generate significant income.

Certain savings options, such as life insurance, offer preferential tax treatment after eight years, with an annual allowance of €4,600 for a single person or €9,200 for a couple. This mechanism can increase the net return.

In addition, investing in certain financial products can qualify for tax benefits. For example, when the investment is made through mutual funds or SICAVs, they must report certain information to the tax authorities, which can affect the taxation applied under Article 41 Y of Annex III to the French General Tax Code (CGI).

It is also worth noting that different rates can apply depending on the size of the company invested in. Reduced rates may apply to companies of certain sizes in 2020 and 2021.

Good to know : In short, to optimise the return on a substantial sum such as €300,000, understanding taxation and the various tax wrappers available is essential. Talking to an independent tax adviser can help navigate these complexities and better assess the potential of one's savings.
