How This Calculator Works
Enter your current Livret A balance, monthly deposit, the regulated rate, and the years. The calculator compounds the balance and shows the estimated value and tax-free interest. The Livret A is fully liquid (withdraw anytime), capital-guaranteed, and its interest is exempt from income tax and social charges.
The Formula
Future Value with Regular Contributions
P = starting amount, PMT = monthly contribution, r = monthly rate (annual ÷ 12), n = number of months
Worked Example
A €5,000 balance plus €200 a month for 5 years at 3% grows to about €18,737 — with roughly €1,737 of tax-free interest. The Livret A is a regulated French savings account held by a large share of the population: the interest rate is set by the government (revised periodically), the capital is guaranteed and fully available at any time, and — its key advantage — the interest is completely exempt from income tax and social charges (prélèvements sociaux). It has a deposit ceiling (currently €22,950 for an individual).
Key Insight
The Livret A is the cornerstone of French household savings, and its appeal is the combination of safety, liquidity, and tax exemption rather than high returns. Key features: the rate is regulated — set by the government (historically via a formula tied to inflation and money-market rates, though the government can override it) and reviewed at set intervals, so it can change over your saving period; the capital is guaranteed (no risk of loss); the money is fully liquid (withdraw any time with no penalty); and crucially the interest is exempt from both income tax and social charges, unlike most French investment income which is taxed (often via the 30% flat 'PFU' / prélèvement forfaitaire unique). There's a deposit ceiling (currently €22,950 for individuals; higher for associations), and you can hold only one Livret A per person. A technical nuance this estimate simplifies: Livret A interest is calculated by fortnight (the 'quinzaine' rule) — deposits earn from the 1st or 16th after they're made and withdrawals lose interest from the start of the quinzaine — so to maximise interest, deposit just before the 1st or 16th and withdraw just after. Because the rate is modest and capped, the Livret A is best as a tax-free emergency fund and short-term safe savings, not a long-term wealth builder — for higher returns the French typically use the Livret de Développement Durable et Solidaire (LDDS, similar but separate ceiling), the assurance-vie (life insurance wrapper, tax-advantaged for longer horizons), or a PEA (equity savings plan). This calculator estimates the tax-free growth; remember every euro of interest shown is free of tax and social charges, which is the Livret A's defining benefit.
Frequently Asked Questions
How is Livret A growth calculated?
Your balance and monthly deposits compound at the regulated rate. A €5,000 balance plus €200/month for 5 years at 3% grows to about €18,737, with roughly €1,737 of tax-free interest. (Livret A officially uses a fortnightly 'quinzaine' interest rule, so this is a close estimate.)
Is Livret A interest tax-free?
Yes — completely. Livret A interest is exempt from both income tax and social charges (prélèvements sociaux), unlike most French investment income (often taxed at the 30% flat PFU). This tax exemption, combined with capital guarantee and full liquidity, is the Livret A's main advantage.
Who sets the Livret A rate?
The government — it's a regulated rate, historically set via a formula linked to inflation and money-market rates but with the government able to override it, and reviewed periodically. So the rate can change during your saving period, which is why this projection is an estimate.
Is there a limit on the Livret A?
Yes — a deposit ceiling (currently €22,950 for an individual; higher for associations), and you may hold only one Livret A per person. Interest can accrue beyond the ceiling, but you can't deposit new funds once the balance reaches the cap. This calculator doesn't enforce the ceiling.
Is the Livret A a good investment?
As a safe, liquid, tax-free home for an emergency fund and short-term savings, yes — but the regulated rate is modest and the balance is capped, so it's not a long-term wealth builder. For higher returns the French typically also use the LDDS, an assurance-vie, or a PEA, accepting more risk or less liquidity for greater growth potential.

Methodology & Review
The future value compounds a starting balance and a fixed monthly deposit at the annual rate, compounded monthly for simplicity. It assumes deposits at month end and a constant rate; the actual Livret A computes interest by fortnight (quinzaine) and the regulated rate can change, and the balance is capped, so this is an estimate.
