Between Book A and LDDS, the right choice depends mainly on your actual use of savings. Both booklets are regulated, secure, challenging and available at any time. The difference is therefore made on the ceiling, the conditions of access and the place you want to give to this savings in your financial organization.
Booklet A and LDDS: two booklets close, but not interchangeable
Booklet A and LDDS, for Sustainable and Solidary Development Booklet, belong to the same family of regulated savings products. Their Rate is set by the State, their interest is exempt from income tax and social levies, and the money remains available without withdrawal costs.
This proximity explains why many savers compare them. In fact, they often serve the same purpose: to welcome a precautionary savings, finance a short-term project or keep a cash amount waiting for a more engaging decision. More than four in five French people hold a Book A, which shows its central place in daily savings.
Booklet A: the simplest reflex
Booklet A is the most accessible of both. It can be opened by a major or minor person, within the limit of one Book A per person. Its ceiling is 22 950 €, excluding capitalised interest. It is therefore the most comfortable booklet if you are looking to build up an important reserve without taxation or market risk.
His seniority also played in his favour. Created in 1818, it became a familiar savings medium, used by both parents for a child and by the assets or pensioners to secure part of their cash flow.
LDDS: A more focused reserve
The LDDS works almost like a twin Book A, but with a lower ceiling: 12 000 €excluding interest. It is mainly aimed at persons who are tax domiciled in France, with rules related to the tax home. Depending on the situation, the opening for a minor can be more framed than for a Book A.
Its particularity also lies in the destination of the funds collected, oriented towards sustainable development and solidarity. For savers, this does not change liquidity or taxation, but it gives a more citizen placement.
Limit, rate, taxation: the comparison that really counts
Before choosing, one must look at the concrete characteristics. Book A and LDDS are not distinguished by their taxation or availability, but mainly by their capacity and opening conditions.
| Criteria | Book A | LDDS |
|---|---|---|
| Payment ceiling | 22 950 € | 12 000 € |
| Rates: | State-regulated rates | State-regulated rates |
| Rate benchmark | 3.0% in February 2023 | 3% in 2023 |
| Taxation | Interest not taxable | Interest not taxable |
| : 24/7 customer support is ideal, especially if you trade at unusual times. | Possible withdrawals at any time | Possible withdrawals at any time |
| Calculation of interest | Fifteen, 1st and 16 of each month | Fifteen, 1st and 16 of each month |
| Security | State guaranteed funds | State guaranteed funds |
The rate of the two booklets is revised, in principle twice a year, around 1 February and 1 August. You must therefore check the current rate when you open or feed your booklet. But the reasoning of choice remains the same: at the same rate, the ceiling and use take precedence.
Interest is calculated according to the 15th rule. A payment begins to produce interest from the next 15 years and a withdrawal ceases to produce interest from the previous 15 years. In practice, depositing just before the 1st or the 16th, and then withdrawing immediately after these dates, makes it possible to better respect this mechanics. This is not a spectacular optimisation, but on a regular saving, it avoids unnecessarily breaking remuneration. Money enters, remains placed on a full fortnight, generates interest, then these interests in turn join the capital.
Which booklet to choose according to your saving profile?
The question is not just which one has the most value. Where the rate is the same, the return is equal. Instead, you have to start from your situation: amount to place, horizon, need for withdrawal and personal goal.
Precautionary savings: priority at Book A
If you start your security savings, Book A is often the first choice. Its ceiling of 22 950 € allows to build a solid reserve, especially if you target the equivalent of 3 to 6 months of income, a range often used to absorb an unforeseen event such as a car breakdown, temporary loss of income, medical expenses or a move.
Its great accessibility also makes it convenient for a family. A parent or grandparent may want to help a child build up a first saving while maintaining a simple, legible and tax-free support.
To complete a Booklet A already well filled: LDDS becomes logical
If your Booklet A approaches its ceiling, the LDDS is the natural suite. It adds up to 12 000 € with the same tax comfort and availability. For a couple, the combination can become very effective, as each can hold his own booklets in accordance with the applicable rules.
The LDDS is also relevant if you want to separate your envelopes. Booklet A for emergencies, LDDS for a medium-term project such as work, a major purchase or a holiday reserve. This mental separation avoids mixing all expenses into a single balance.
To give meaning to its savings: symbolic advantage to the LDDS
The LDDS is distinguished by its focus on sustainable and inclusive development. If two products have comparable performance and safety, this criterion may influence the decision. It does not turn your booklet into an impact investment in the strict sense, but it gives additional consistency to part of your savings.
For a saver who wants to remain cautious while avoiding a purely dormant logic, the LDDS therefore offers an interesting compromise: liquidity, guarantee, challenges and citizenship.
Benefits, limits and points of vigilance before opening
The main advantage of both booklets is their simplicity. There are no opening costs, no interest tax, no social levies and no risk of fluctuation as in financial markets. In the event of bank failure, the funds are guaranteed by the State, with a specified repayment period of 7 working days.
But this security has a counterpart. The return remains framed, so you don't choose the bank to get better pay on Book A or LDDS. Opening up in one bank rather than another can improve online management experience, mobile application or ease of transfer, but not the regulated rate itself.
Choose Book A If you want the highest ceiling, a simple opening or family savings. Choose the LDDS If your Book A is already advanced, if you want to compartmentalize your savings or if the long-lasting and solidary orientation counts for you. Use both if you need a large liquid reserve, without taxes and without risk taking.
Another point deserves attention: it is forbidden to hold several Booklets A in his name, and the LDDS also obeys rules of detention. Before opening, the bank normally checks that you do not already own the same product elsewhere.
When the ceilings are reached, what about extra savings?
Once Book A and LDDS are completed, it becomes useful to distinguish the money that must remain available from the money you can place longer. Keeping too much cash can reassure, but beyond your need for precaution, some of your savings may aim at other goals.
For eligible households, the SARA, or Popular Savings Booklet, may be a lead to be examined, as it is intended for people meeting certain income conditions. It remains in the world of regulated savings, with a logic of security and advantageous taxation.
For medium- or long-term savings, other solutions can be considered depending on your horizon, risk tolerance and projects: life insurance, futures account, savings plan, invested media or more diversified heritage solutions. These options do not replace Book A or LDDS in their immediate reserve role, but they can take over when your money is not meant to be withdrawn quickly.
In summary, if you hesitate between Booklet A or LDDS, start with Booklet A for its higher capacity and accessibility. Then add the LDDS to increase your available savings, organize your projects or give a more supportive orientation to part of your savings. The right choice is not necessarily one against the other. For many savers, the best answer is to use them in the right order.
