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
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.
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.

Methodology & Review
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.
