12 Mistakes to Avoid with Your Life Insurance in 2026

Mistakes that prove costly over the long term

In 2024, France had nearly 54 million life insurance contracts in circulation according to France Assureurs, for a total outstanding balance exceeding 1 900 billion euros. Despite this popularity -- making it the preferred savings vehicle in France, ahead of the Livret A -- many savers make mistakes from the very start that can cost them thousands, or even tens of thousands of euros over time. These mistakes are all the more costly because they occur at the beginning of the savings journey, when every poorly invested euro deprives the saver of decades of compound interest.

The good news is that these mistakes are easily avoidable with a minimum of information. Here are the 12 most common pitfalls and how to steer clear of them for a strong start.

Mistake 1: Choosing your bank's default contract

This is the most widespread and costliest mistake over the long term. When your bank adviser offers you the in-house life insurance policy during a routine meeting, it is tempting to accept out of convenience, trust, or simply through lack of awareness of alternatives. Yet traditional bank contracts rarely rank among the most competitive on the market, whether in terms of fees, euro fund returns, or choice of investment funds.

Our advice: always compare at least 3 contracts before subscribing. Online comparisons let you quickly see the differences in fees and fund selection. Favour online contracts (Linxea Spirit 2, Lucya Cardif, Boursorama Vie) that systematically offer better terms than traditional bank networks.

Mistake 2: Ignoring the impact of fees

Many savers underestimate the cumulative impact of fees on their final wealth. "0.5% difference is nothing", they think. In reality, over 25 years, this seemingly trivial difference translates into tens of thousands of euros in lost returns, because of the multiplier effect of compound interest: fees apply each year to an ever-growing balance.

The gap between 0.5% and 1.5% in fees represents over 55 000 euros in lost returns. That is the equivalent of a new car "gifted" to the insurer through the effect of compounding fees. And this calculation does not even include entry fees, which on some bank contracts take 2% to 3% from every euro invested before it even starts working.

Fees come in several layers: entry fees (0% to 3%), contract management fees (0.5% to 1%), fund-level fees (0.05% to 2% depending on the unit-linked fund chosen), and possibly switching fees (0% to 0.5% per transaction). An online contract like Linxea Spirit 2 or Lucya Cardif allows you to keep the first three layers to a minimum, especially if you invest in low-cost ETFs.

Our advice: aim for management fees below 0.6% on the euro fund and 0.7% on unit-linked funds. Categorically refuse any contract with entry fees. In 2026, paying entry fees on a life insurance contract is an unjustifiable anachronism.

Mistake 3: Neglecting the beneficiary clause

The beneficiary clause determines who will receive the capital on the policyholder's death. It is one of the most powerful features of life insurance for wealth transfer, yet many policyholders fill it in hastily, keep the standard clause without understanding it, or worse, forget to update it after major life events.

Common errors:

• Writing simply "my heirs" without further detail (standard succession rules then apply, without the specific advantages of life insurance for out-of-probate transfers)
• Naming one's spouse without providing for the spouse's prior death (no "a defaut" clause)
• Forgetting to update after a marriage, divorce, or birth
• Naming beneficiaries too vaguely ("my children" without specifying "born or to be born, living or represented")

The recommended standard clause is: "My spouse, not legally separated or divorced, failing which my children born or to be born, living or represented, in equal shares, failing which my heirs."

Philippe, 45, divorced and remarried without updating his beneficiary clause. His ex-wife remains the primary beneficiary of his 150 000 euro contract. On his death, she would receive the entire capital, not his new wife or children. A mistake that takes five minutes to correct on the contract's client portal, yet one that thousands of French savers make every year.

Our advice: reread your beneficiary clause at every life event (marriage, divorce, birth, death). Consult a notary for complex situations (blended families, cohabitation, civil partnership).

Mistake 4: Waiting to "lock in the date"

The 8-year tax clock for life insurance starts on the day you subscribe, not on the day of your first significant contribution. Every month you wait pushes back access to the favourable tax treatment (allowance of 4 600 euros for a single person or 9 200 euros for a couple on gains from withdrawals).

Margot, 28, an IT engineer, is hesitating between opening her life insurance now with 500 euros or waiting until she has 10 000 euros in savings. If she waits 3 years, she will reach the 8-year tax threshold at 39 instead of 36. Three years of favourable taxation lost, for zero opening cost. And if she needs to make a large withdrawal at 36, she would pay the flat-rate withholding of 12.8% on gains instead of 7.5% with allowance.

Our advice: open your contract today with the required minimum (often 100 to 500 euros on online contracts). You can increase your contributions later. "Locking in the date" is free, fast, and irreversible. This is the simplest and most rewarding piece of advice in this article.

Mistake 5: Putting all your eggs in one basket

Investing 100% in the euro fund when you have a 15-20 year horizon is a classic diversification error. With inflation at 2-3% per year, a 2.5% euro fund offers a near-zero real return, or even negative after social charges. Your capital maintains its nominal value but gradually loses purchasing power.

Conversely, investing 100% in unit-linked funds when you might need the money in the short term exposes you to the risk of having to sell during a downturn. In 2022, equity markets lost between 10% and 20% depending on the index: a saver needing to withdraw from their contract that year would have crystallised a significant loss.

Our advice: adapt your allocation to your actual investment horizon, not to your fear of risk at a given moment. Over a 15-year horizon and beyond, equity markets have historically never lost money (on major global indices). The risk lies in underperformance, not in volatility.

Mistake 6: Opening only one contract

There is nothing stopping you from opening several life insurance policies. On the contrary, a multi-contract strategy is recommended by all wealth management advisers and offers numerous advantages:

• Insurer diversification: protection against an institution's failure (the FGAP guarantee is limited to 70 000 euros per insurer per policyholder)
• Tax optimisation: choosing the most advantageous contract (the oldest or the one with the fewest gains) for a given withdrawal
• Specialisation: one contract for high-performing euro fund, another for ETFs in self-managed mode, a third in managed allocation at Yomoni or Nalo

Antoine and Marie, a couple in their thirties, opened 3 contracts each with distinct objectives: a Linxea Spirit 2 for long-term ETF investment, a Lucya Cardif for the high-performing euro fund, and a Nalo managed contract for the children's education fund with a specific beneficiary clause.

Our advice: aim for 2 to 3 contracts with different insurers. Opening them early lets you lock in the date on all simultaneously. The opening cost is nil on online contracts.

Mistake 7: Investing a large sum all at once in unit-linked funds

Investing 50 000 euros in one go in unit-linked funds risks entering at a market high. If markets drop 20% in the following months, you lose 10 000 euros in value and the psychological impact is devastating, especially for a beginner saver.

The technique of gradual investment (Dollar Cost Averaging) involves spreading the investment over 6 to 18 months, investing a fixed amount at regular intervals. This approach does not maximise performance (investing all at once is statistically superior in 2 out of 3 cases), but it minimises timing risk and emotional stress.

Example: Francois has 60 000 euros to invest in unit-linked funds. Instead of investing everything on 1 January, he programmes 10 000 euros per month over 6 months via the gradual investment option on his Boursorama Vie contract. If the market drops 15% in month 3, he buys more units at a reduced price. If the market rises steadily, he benefits from part of the upside from the first month.

Our advice: for unit-linked funds, spread significant investments (over 10 000 euros) across 6 to 12 months. For euro funds, a lump-sum investment is acceptable since the capital is guaranteed.

Mistake 8: Not understanding the difference between insurer and distributor

The distributor (Linxea, Boursorama, Meilleurtaux) is the commercial intermediary that markets the contract and manages the client relationship. The insurer (Spirica, Generali, Cardif, Suravenir) is the entity that legally holds the contract, manages the euro fund, and guarantees contractual commitments.

It is the insurer that determines the euro fund return, the strength of the capital guarantee, and the contract's long-term viability. If the distributor goes bankrupt (which happens very rarely), your contract continues with the insurer without any interruption. Conversely, if the insurer encountered difficulties (an extremely unlikely scenario for major systemic insurers), the impact would be far more significant.

Key pairings to know:

• Linxea Spirit 2 is insured by Spirica (subsidiary of Credit Agricole Assurances)
• Boursorama Vie is insured by Generali
• Lucya Cardif is insured by BNP Paribas Cardif
• Linxea Avenir 2 is insured by Suravenir (subsidiary of Credit Mutuel Arkea)

Our advice: check the insurer's financial strength (credit rating, market share, balance sheet size), not just the distributor's website design. Diversify your contracts across different insurers to limit concentration risk.

Mistake 9: Forgetting to set up scheduled contributions

Many people open their life insurance, make the initial contribution, then forget about it for years. Without regular contributions, the compound interest effect is severely limited. It is like planting a seed and never watering it: it might grow, but never as fast as with regular watering.

With just 200 euros per month, the capital is multiplied by 8 compared to a simple initial contribution with no subsequent payments. The power of compound interest works all the more strongly when contributions are regular and start early.

Our advice: set up a scheduled contribution from the moment you open the contract, even a modest one (50 euros/month). You can increase it later with each pay rise or reduction in expenses. Automation is the key to savings discipline.

Mistake 10: Not using managed allocation when you are a beginner

Beginners who choose self-management often find themselves paralysed by the choice of funds. The result: they leave everything in the euro fund out of fear of making a mistake, or they pick unit-linked funds at random, often the most visible ones on the list (which are not necessarily the best).

Managed allocation (gestion pilotee) entrusts the investment allocation to professionals who diversify according to your risk profile and investment horizon. The additional fees (0.2% to 0.3% per year on top of contract management fees) are largely offset by optimised and disciplined management.

Robo-advisors like Yomoni and Nalo offer 100% ETF-based managed allocation at reduced fees, ideal for beginners. Yomoni offers profiles ranging from 1 (very conservative) to 10 (very dynamic), with investment in globally diversified ETFs. Nalo offers a project-based approach (retirement, property purchase, children's education) with automatic gradual de-risking as the target date approaches.

Our advice: if you have no financial knowledge, start with managed allocation at Yomoni or Nalo. You can switch to self-management when you feel ready and have acquired sufficient financial literacy to choose your own funds.

Mistake 11: Confusing life insurance with death insurance

This is a persistent misunderstanding that discourages some savers from opening a life insurance contract, thinking it is a "morbid" product. Life insurance is first and foremost a savings and capitalisation product, not a protection policy.

Life insurance is for:

• Saving and growing your capital over the long term
• Benefiting from significant tax advantages (no taxation during the savings phase, allowances after 8 years)
• Passing on wealth under favourable tax conditions (152 500 euro allowance per beneficiary for contributions made before age 70)

Death insurance (assurance deces) is for:

• Protecting your family in the event of premature death (payment of a lump sum or annuity)
• Covering a mortgage (borrower's insurance is a type of death insurance)

The two products are complementary but do not substitute for each other. A young working person with small children typically needs both: death insurance to protect their family in case of premature death, and life insurance to build long-term wealth.

Our advice: do not refuse to open a life insurance policy thinking it is a bet on your death. It is above all an exceptional savings tool -- arguably the most versatile in the French financial landscape.

Mistake 12: Not informing your loved ones

Every year, billions of euros lie dormant in life insurance contracts whose beneficiaries are unaware of their existence. The Eckert law of 2014 required insurers to actively search for beneficiaries of unclaimed contracts, but there remain many contracts whose capital has never been claimed due to beneficiaries not being informed.

A few simple precautions to prevent your contract from being forgotten:

• Inform your beneficiaries of the contract's existence (without necessarily revealing the amount)
• Keep the subscription documents in a location known to your loved ones (safe, family file)
• Check the AGIRA website (agira.asso.fr) to see if you are yourself the beneficiary of a forgotten contract
• Record the contract in a will or a letter of wishes

Our advice: file your membership certificate with your important documents and inform at least one trusted person of the contract's existence and the insurer's identity.
