Not all assurance-vie contracts are equal. At the same investor profile, investment horizon and fund selection, your returns will vary significantly. The reason is simple and often underestimated: annual fees.
For readers unfamiliar with the term: in France, assurance-vie is not life insurance in the anglo-saxon sense. It's a flexible, tax-efficient savings and investment wrapper, closer in spirit to an ISA (UK) or a 529 plan (US) — used both to invest over the long term and to pass on wealth to chosen beneficiaries. See our glossary entry on assurance-vie for the full tax treatment.
Why fees change everything
Many investors underestimate the long-term impact of a few tenths of a percentage point in annual fees on the growth of their wealth. Yet the mechanics of compounding are relentless: 1% less in annual fees over 25 years can represent tens — sometimes hundreds — of thousands of euros, depending on your starting capital.
Do the maths yourself: if you've already built up €25,000, €50,000 or €100,000 since starting your working life, the difference between a contract charging 0.33% in total fees and one charging 2% can be staggering over 25 years. Genuinely so.
The market reference: Lucya CNP
Among the contracts available today, Lucya CNP stands out as the reference on fees. I have no remuneration arrangement whatsoever with Lucya or with CNP Assurances — this is a purely objective assessment, based on the numbers.
In practice: you can invest in the S&P 500 — the world's benchmark index — while benefiting from all the tax and succession advantages of French assurance-vie, for just 0.33% in total annual fees.
A choice of low-cost ETFs on the main indices
Lucya CNP gives access to 15 commission-free ETFs covering the main global indices. Here's a selection:
| ETF | ISIN | Annual fees (TER) |
|---|---|---|
| State Street SPDR S&P 500 ETF USD Acc | IE000XZSV718 | 0.03% |
| UBS Nasdaq-100 ETF USD Acc | IE000SB4G4I4 | 0.13% |
| UBS Core MSCI World ETF USD Acc | IE00BD4TXV59 | 0.06% |
TERs (Total Expense Ratios) are those published by the fund managers at the time of writing. They can change. Lucya CNP's own unit-linked management fees are not included in this table.
What your bank adviser will never tell you
Your bank adviser will never mention Lucya CNP to you — because they only sell their own bank's products. That's not a criticism: it's structural. But it means that if you don't research this yourself, or with the help of an independent adviser, you'll lose tens of thousands of euros — and over time, hundreds of thousands.
An independent wealth-management adviser, paid exclusively through fees and with no retrocessions whatsoever, has only one interest: recommending the best products available on the market. That's precisely the model paro conseil operates on.
And beyond the PEA ceiling?
The PEA remains the most tax-efficient vehicle for long-term equity investing in France — exempt from income tax after 5 years, 0% management fees in self-directed mode. But its contribution ceiling is capped at €150,000.
Beyond that, or if you want the succession benefits of assurance-vie (a €152,500 allowance per beneficiary), Lucya CNP is today the best option available on the market for low-cost investing.
The optimal strategy depends on your personal situation, your marginal tax bracket, your horizon and your succession objectives. That's what we build together during a first consultation.

What are the fees on Lucya CNP?
Lucya CNP charges 0.30% in annual management fees on unit-linked funds, the lowest rate on the French market. On top of that: 0% entry fees on contributions, 0% fees on fund switches, and fees on the underlying funds themselves (from 0.03% for the best ETFs). Total recurring annual cost is therefore close to 0.33% to 0.45%/year depending on the funds chosen.
Is Lucya CNP really the best assurance-vie contract on the market?
It's one of the standout references in 2026, particularly for self-directed, ETF-based management. On the criterion of unit-linked management fees (0.30%), it is today the most competitive rate on the French market accessible to individuals. This doesn't mean it suits every profile, though — the analysis should take into account your objectives, horizon and allocation strategy.
What funds are available on Lucya CNP?
The contract offers more than 1,200 funds in self-directed management: 120 multi-issuer ETFs (Amundi, iShares, Vanguard, SPDR, UBS, Xtrackers, Invesco...), more than 540 actively managed mutual funds, 12 SCPI with no entry fees, 5 private-equity funds and one euro fund. This same range is available on both the assurance-vie contract and the Lucya CNP PER, giving you enough breadth to build a diversified, self-directed allocation without needing to hold several contracts.
