Profitable investment: which investments to choose to make your capital grow

Finding a profitable investment is the primary objective of any saver. But behind this generic term there are very different realities: an investment can show a high gross return while being unprofitable once fees and taxes are deducted, or conversely deliver a modest but regular and tax-advantageous return. This guide reviews the 10 most profitable investments available in France in 2026, their level of risk, their optimal horizon and the criteria for choosing the one that corresponds to your situation and your budget.

What is a profitable investment?

Definition of the profitability of an investment

A profitable investment is an investment that generates a return that exceeds inflation and the associated costs (management fees, entry fees, taxes, social security contributions), over the horizon defined by the investor. Profitability is therefore not limited to the posted interest rate: it is calculated in net worth, after deduction of anything that affects performance.

Gross, net, real return: three concepts to distinguish

• The gross yield : displayed investment performance before any drawdown
• The net return : performance after management fees, entry fees, taxation and social security contributions
• The real return : net performance minus inflation, which measures the effective wealth of savers

An investment is only truly profitable if its real return is positive over the target horizon.

How do you measure the profitability of an investment?

Several indicators make it possible to objectively measure the profitability of an investment:

• IRR (Internal Rate of Return) : annualized return over the life of the investment, taking into account cash inflows and outflows
• The multiple on invested capital (MOIC) : ratio between the final capital and the initial capital. A multiple of 2x means that the capital has doubled
• The average annual return : annualized performance over a given period, useful for comparing several investments
• Volatility : magnitude of variations in performance, associated risk indicator

Over a long period of time, the difference in profitability between two investments can come as much from fees and taxes as from gross performance. An active fund billed at 2% per year may underperform an ETF at 0.2% over 20 years, at an equivalent allocation, simply because of the cumulative cost of fees.

The 2026 context: key rates, inflation and monetary policies

The macroeconomic context has a direct impact on the profitability of investments. In 2026, several factors are influencing savers' decisions:

• The key rates of the European Central Bank (ECB) in the eurozone directly influence the remuneration of regulated passbooks, euro funds and bonds
• Inflation, more contained than in 2022—23, remains around 2 to 3% in most eurozone countries
• In the United States, the Fed's monetary policy and the performance of the S&P 500 continue to drive the profitability of globally listed stocks
• Expansive monetary policies in recent years have inflated asset values, making selection more important than ever.

This context favors investments that are geographically diversified and asset classes that are uncorrelated with currency cycles (real estate, private equity).

The top 10 most profitable investments in 2026

‍

1. The Livret A and the LDDS: safety above all

The A booklet and the LDDS (Sustainable and Solidarity Development Booklet) are the most used regulated booklets in France. Capital guaranteed by the State, interests exempt from taxes and social security contributions, total liquidity. Ceilings: 22,950 euros for the A booklet, 12,000 euros for the sustainable and solidarity development booklet. The Livret A rate has been 1.5% since February 1, 2026, which makes it less profitable than inflation: its function remains above all security and liquidity, not capital growth. The young savings account, reserved for 12-25 year olds, completes this range of savings accounts for young savers.

2. LEP: the most profitable risk-free investment

The popular savings account is reserved for modest taxpayers (reference tax income under a certain ceiling). Its rate has been 2.5% since 1 February 2026, slightly above inflation and significantly higher than the Livret A. Ceiling: 10,000 euros. It is the most profitable risk-free investment available in France for eligible households, without any risk of capital loss.

3. Life insurance in euro funds

Life insurance remains a pillar of French savings with 2,107 billion euros in assets at the end of 2025 according to France Assurers (January 2026), the threshold of 2,000 billion having been crossed in January 2025. Euro funds guarantee capital and offer an average return of 2.6% in 2024 and 2.65% (preliminary estimate) in 2025 according to the ACPR. Taxation becomes advantageous after 8 years, with an annual deduction on capital gains (4,600 euros for a single person, 9,200 euros for a couple).

4. SCPIs: the accessible paperstone

SCPIs (Société Civiles de Placement Immobilier), also called paper money, allow you to invest in rental real estate (offices, shops, logistics, health) without managing the property yourself. The average distribution rate is around 4.5 to 5.5% per year, distributed in the form of regular income. However, be careful: the 2025 Global Annual Performance (PGA) is only +1.46%, due to an average price drop of -3.45%. The payout rate alone is therefore flattering and masks the recent depreciation of some SCPIs. An investor must reason in terms of overall performance, distribution plus variation in the share price.

5. Listed stocks and ETFs

Investing in the stock market via individual shares or ETFs (listed index funds) makes it possible to capture the performance of global financial markets, especially those in the United States (S&P 500) and the eurozone (CAC 40, Stoxx 600). Over a long period (15 to 20 years), the major indices delivered 6 to 10% per year on average. Short-term volatility remains high but subsides over the long term. Primarily to be included in an equity savings plan (PEA) to optimize taxation.

6. Direct rental real estate investment

Direct real estate investment remains one of the classics of French savings. Gross profitability varies between 3 and 7% depending on the zone, but net profitability depends heavily on taxation (LMNP, land deficit), fees (property tax, charges, management) and any work. The leverage effect of credit remains a major asset for building wealth.

7. Term accounts

The term account locks in an amount for a defined period of time (3 months to 5 years) in exchange for a guaranteed fixed interest rate. No capital risk, taxation at the PFU 30%. Useful for optimizing excess cash beyond the limits of regulated passbooks.

8. Corporate bonds

Corporate bonds offer a higher yield than government bonds, against an increased risk of default. Typical gross yield: 3 to 6% depending on signature quality. Accessible via bond investment funds (UCITS) or dedicated ETFs.

9. Real estate crowdfunding

Real estate crowdfunding makes it possible to finance real estate transactions (promotion, property dealer) in exchange for an annual contractual return often between 8 and 11%. Short horizon (12 to 36 months), one-time payments, no management. But this asset class presents a very real risk of promoter default, often underestimated by individuals: according to the AMF, the delay rate reached 60.2% of the amounts for the 2019 vintage, and the Forvis Mazars/France FinTech 2025 Barometer indicates that approximately one project out of two is encountering difficulties (delay, extension, restructuring, default). The contractual performance shown can therefore be reduced, or even completely lost in the event of failure of the project leader.

10. Private equity

Private equity (capital investment in unlisted companies) has historically been the most profitable asset class over a long period of time. According to France Invest/EY (2025 study, data as of 31/12/2024), private equity funds have a net 10-year IRR of 12.4%, higher than most listed asset classes, with a significant dispersion depending on the managers.

Historically, this strategy was reserved for institutional investors with an entry ticket of several hundred thousand euros. Fundora makes these strategies accessible to individuals via FPCI and SPV structures that pool subscriptions. Management is carried out under mandate by Kyoseil Asset Management, a management company approved by the AMF, with a rigorous selection of funds and a multiple objective of between 2.5x and 4x over the investment horizon.

How to choose the most profitable investment according to your profile

The pocket approach: the basis of a profitable strategy

A profitable investment strategy is rarely based on a single investment. The logic of the three pockets effectively structures an asset:

Allocation by risk profile

Three main profiles allow you to structure your allocation according to your capacity and your acceptance of risk taking:

• Careful profile : 70% security, 25% bonds, 5% shares. Target return: 2 to 4% per year
• Balanced profile : 30% security, 30% bonds, 35% shares, 5% unlisted. Target return: 4 to 7% per year
• Dynamic profile : 10% security, 20% bonds, 55% shares, 15% unlisted. Target return: 7 to 10% per year

‍

‍

The more dynamic the profile, the more the share of assets with high potential (shares, private equity) increases, which increases the expected profitability but also the volatility and the risk of loss.

Diversifying across several dimensions

Diversification is the most effective way to optimize the risk/return combination. It must be organized on four axes:

• By asset class : shares, bonds, real estate, unlisted, liquidity
• By geography : France, eurozone, United States, emerging markets
• By sector : technology, health, energy, finance, consumption
• By horizon : short, medium and long term

A profitable investment is always part of a global diversification strategy, never as a concentration on a single asset.

The pitfalls to avoid in order to preserve the profitability of your capital

Several classic mistakes permanently penalize the profitability of an asset:

• Underestimating the impact of fees : 1% per year over 20 years represents nearly 20% less final capital
• Ignoring taxation : a successful investment in the wrong envelope loses a significant part of its net profitability
• Focus your savings on a single asset or sector, which maximizes the risk of capital loss
• Investing without a horizon : the profitability of a risky investment (shares, private equity) only fully reveals itself over a minimum of 7 to 10 years
• Give in to panic during downturns and liquidate your investments at the worst time
• Seek short-term performance without taking into account the risk/return ratio
• Neglecting inflation which mechanically erodes the purchasing power of amounts left on low-paid devices
• Forget the entrance fees when selecting an investment fund, which reduces performance from the start

FAQS

What is the most profitable investment in 2026?

No investment is the most profitable in absolute terms. Over the long term (10 years and over), private equity (net IRR 10 years 12.4% according to France Invest/EY) and equities (MSCI World 11.68% annualized for 10 years in EUR) show the best returns, with significant volatility for equities and strong illiquidity for private equity. In the short term, 2.5% LEP remains the most profitable risk-free investment for eligible households. The right choice depends on your profile, your horizon and your risk tolerance.

How to invest 10,000 euros in a profitable way?

With 10,000 euros, a diversified approach is possible: 3,000 to 5,000 euros in precautionary savings (passbook A, LDDS), 3,000 to 5,000 euros in multi-support life insurance, and 1,000 to 2,000 euros in high-potential investments (ETF, SCPI, or private equity via Fundora, which makes this asset class accessible to individuals via FPCI/SPV structures).

Should you prefer the stock market or real estate investment for a profitable investment?

Both have their advantages and complement each other in a diversified strategy. The stock exchange offers liquidity, long-term performance (6 to 10% per year) and easy access via ETFs. Real estate investment (directly or via SCPI) generates regular income, partially protects against inflation and offers a decorrelation of financial markets. The best strategy is often to combine the two according to your profile.

Is private equity really the most profitable investment?

Over a long period of time, private equity funds show the best annualized returns. According to France Invest/EY (2025 study), the 10-year net IRR is 12.4%, higher than most listed asset classes. But the dispersion is strong: the best funds deliver returns well above 12%, while the less efficient ones struggle to reach 5%. The selection of the manager is therefore crucial. Illiquidity (capital locked for 5 to 10 years) is also to be included in the decision.

How to invest in private equity with a small budget?

Private equity was historically reserved for institutional investors with tickets worth several hundreds of thousands of euros. Fundora makes this asset class accessible to individuals via FPCI and SPV structures that pool subscriptions. Management is provided under mandate by Kyoseil Asset Management, a management company approved by the AMF.
