France Assurance Vie Calculator: Investment Growth

Estimate what a French assurance vie grows to from a lump sum at a steady return — France's most popular savings wrapper, prized for flexible investing, favourable tax on gains after eight years, and inheritance advantages.

Amount & Growth
The lump sum placed in your assurance-vie contract (or its current value).
A euro fund (fonds en euros) is capital-guaranteed with a lower return; unit-linked supports (unités de compte) invest in markets for higher expected return with risk. Use a rate matching how your contract is invested.

How This Calculator Works

Enter the amount invested, the return you expect, and the years invested. The calculator compounds the balance and shows the projected contract value and the growth. An assurance vie holds either a capital-guaranteed euro fund or market-linked unit-linked supports (or both); gains are only taxed when you withdraw, and the tax is reduced once the contract is over eight years old.

The Formula

Future Value of a Lump Sum

FV = PV × (1 + r)^n

PV = present value, r = annual rate, n = number of years

Worked Example

A €30,000 assurance vie growing at 4% for 15 years reaches about €54,028 — roughly €24,028 of growth. The assurance vie is France's flagship long-term savings product — not just life insurance, but a flexible investment wrapper. You can hold a fonds en euros (capital-guaranteed, lower-yielding) and/or unités de compte (market-linked funds), switch between them, and withdraw at any time. Its appeal is taxation: gains aren't taxed as they accrue, only on withdrawal, and after the contract reaches eight years a generous annual allowance makes withdrawals largely tax-efficient — plus major advantages for passing money to heirs.

Key Insight

The assurance vie is the cornerstone of French personal saving, and its strengths are tax and flexibility rather than the headline return. It's a wrapper, not a single investment: inside it you choose a fonds en euros (capital-guaranteed, modest return, but with social levies taken annually on the interest) and/or unités de compte (unit-linked market funds with higher expected return and risk), and you can arbitrate between them without triggering tax. The defining feature is deferred, then reduced, taxation: gains aren't taxed while they stay in the contract (only social levies on euro-fund interest accrue), and you're taxed only on the gain portion of any withdrawal. Crucially, once the contract passes its eighth anniversary, withdrawals benefit from a generous annual tax-free allowance on the gains (per person), and the gains above it are taxed at a reduced rate — so an old assurance vie is highly tax-efficient to draw on. The 8-year clock starts at opening, so the common advice is to open one early ('prendre date') even with a small amount. The other headline benefit is succession: sums paid in before age 70 pass to named beneficiaries largely outside normal inheritance tax up to a high per-beneficiary allowance, making assurance vie a key estate-planning tool (different, less generous rules apply to premiums paid after 70). Fees matter a lot over time — entry fees, annual management fees on the contract and on unit-linked funds compound against returns, so low-cost online contracts are favoured. This calculator gives a gross, constant-return projection and omits fees, the withdrawal taxation and euro-fund social levies; in practice pick a low-cost contract, use the 8-year allowance when withdrawing, and weigh the euro fund's safety against unit-linked growth.

Le cap des 8 ans : l'abattement annuel qui change tout

Après 8 ans de détention, l'assurance vie devient l'enveloppe la plus fiscalement avantageuse en France pour les gains supérieurs à €4,600. À partir de cette ancienneté, vous bénéficiez d'un abattement annuel de €4,600 (personne seule) ou €9,200 (couple soumis à imposition commune) sur les gains issus de rachats — appliqué chaque année calendaire renouvelable.

Concrètement : un couple peut racheter chaque année jusqu'à environ €9,200 de gains sans aucune imposition au titre de l'impôt sur le revenu. Au-delà de cet abattement, les gains sont taxés à 7,5% (sur les versements inférieurs à €150,000) ou 12,8% (au-delà), plus les prélèvements sociaux 17,2%.

Stratégie classique : faire "prendre date" à un contrat d'assurance vie tôt (même avec un versement initial minimum de €100) pour démarrer le compteur 8 ans le plus tôt possible. Le contrat reste actif sans coût significatif, et au bout de 8 ans vous pouvez l'alimenter et bénéficier immédiatement de la fiscalité allégée.

Le calcul de la part imposable lors d'un rachat partiel

Lors d'un rachat partiel, seule la fraction correspondant aux gains est imposable — pas la partie qui correspond aux versements. La formule officielle : gain imposable = montant racheté − (versements × montant racheté / valeur totale du contrat).

Exemple concret : un contrat avec €50,000 de versements et une valeur actuelle de €75,000 (gains de €25,000 soit 33%). Rachat partiel de €15,000 → gain imposable = 15,000 − (50,000 × 15,000 / 75,000) = 15,000 − 10,000 = €5,000. Sur ce gain de €5,000, l'abattement après 8 ans (€4,600 célibataire) couvre presque tout — taxation effective ≈ zéro impôt sur le revenu.

Important : les prélèvements sociaux (17,2%) sont quant à eux dus en intégralité sur les gains, sans abattement — y compris après 8 ans. Sur l'exemple ci-dessus : €5,000 × 17,2% = €860 de PS dus quel que soit l'âge du contrat. Les fonds en euros voient leurs PS prélevés annuellement (à la source) ; sur les unités de compte, ils ne sont dus qu'à la sortie.

La succession : l'avantage le plus puissant de l'assurance vie

Au-delà de l'épargne, l'assurance vie est l'outil patrimonial dominant en France pour transmettre du capital hors succession classique. Les sommes versées avant les 70 ans du souscripteur bénéficient d'un abattement de €152,500 par bénéficiaire désigné, puis sont taxées à 20% jusqu'à €700,000 et 31,25% au-delà.

Concrètement : un patriarche qui désigne deux enfants comme bénéficiaires peut transmettre jusqu'à €305,000 (2 × €152,500) totalement exonérés, en plus de l'abattement classique de €100,000 par enfant en succession traditionnelle. Soit potentiellement €505,000 transmis à chaque enfant sans aucun droit de succession.

Les versements après 70 ans suivent un régime moins favorable : abattement unique de €30,500 pour l'ensemble des bénéficiaires, puis intégration dans l'actif successoral classique (avec barème de 5%-45%). Conséquence pratique : maximiser les versements avant 70 ans, et préférer le régime des assurance-vie classiques (vs PER) pour la transmission patrimoniale.

Frequently Asked Questions

How is assurance vie growth calculated?

Compound the amount at the expected return over the years: value = amount × (1 + rate)^years. €30,000 at 4% for 15 years grows to about €54,028, roughly €24,028 of growth. This models a single lump sum with no further payments, before fees and withdrawal tax.

What is an assurance vie?

France's flagship long-term savings wrapper — not just life insurance, but a flexible investment account. You can hold a capital-guaranteed euro fund and/or market-linked unit-linked supports, switch between them, and withdraw anytime. Its appeal lies in favourable taxation of gains and inheritance advantages.

How are assurance vie gains taxed?

Only on withdrawal, and only the gain portion — not while the money stays invested (though social levies accrue on euro-fund interest). After the contract reaches eight years, withdrawals get a generous annual tax-free allowance on the gains, with the excess taxed at a reduced rate, making old contracts very tax-efficient.

Why does the eight-year mark matter?

Because the favourable annual tax-free allowance on gains and the reduced tax rate apply once the contract is over eight years old. The clock starts at opening, so many people open an assurance vie early ('prendre date') even with a small amount, to start the eight-year period as soon as possible.

What's the inheritance advantage?

Sums paid in before age 70 pass to named beneficiaries largely outside normal inheritance tax, up to a high per-beneficiary allowance — making assurance vie a key French estate-planning tool. Premiums paid after age 70 follow different, less generous rules. This makes it valuable beyond just investment growth.

The future value compounds an assurance-vie lump sum at the annual return over the years, compounded annually. It assumes a single starting amount with no further payments and a constant return, and does not model contract/management fees, the favourable taxation of gains on withdrawal, or the social levies due on euro-fund interest.
