Practical guide
Same job, same pay, but different rules on length, ending the contract and what you get when it finishes. This guide compares the CDD and the CDI point by point, works out what a fixed-term contract pays on top at the end, and explains how to move from one to the other.
The CDI, the permanent contract, is the normal form of employment in France; the CDD, the fixed-term contract, is an exception reserved for a precise, temporary task: covering for an absent employee, handling extra work, a seasonal job. It cannot be used to fill, on a lasting basis, a job tied to the company's normal activity. Pay can be the same in both, but the length, the way out and what you receive at the end differ a lot. This guide compares them and puts a figure on the gap with an example worked out by the site.
| Point | CDD | CDI |
|---|---|---|
| Length | An end date or a precise purpose; 18 months at most in the general case, renewals included | No end date |
| Renewal | 2 times at most, unless a sector agreement says otherwise, if the contract or an amendment signed before the end provides for it | Not applicable |
| Form | Must be in writing, with its reason stated, handed over no later than 2 working days after hiring | Writing is required for part-time work; for full-time work it is not, but the key information must be given to you |
| Leaving early | Only in limited cases (agreement, serious misconduct, force majeure, unfitness for work, a permanent job elsewhere) | Resignation, dismissal, mutual termination |
| At the end | End-of-contract bonus of 10% of total gross pay, plus untaken holiday | Severance or mutual termination pay depending on the case, untaken holiday |
| Unemployment benefit | Yes when it ends, if the minimum work conditions are met | Yes after a dismissal or mutual termination; as a rule, not after a resignation |
The law forbids paying a fixed-term employee less: their pay cannot be lower than that of a permanent employee with an equivalent qualification, in the same job, in the company. Bonuses, a thirteenth month and job-related benefits follow. The difference comes at the end: the fixed-term contract gives an end-of-contract payment, the prime de précarité, which compensates precisely for the lack of security, and untaken holiday is paid out in one go.
Example: €3,000 gross a month for 12 months, with no holiday taken, on a fixed-term or a permanent contract. Net pay each month is the same, €2,353, i.e. €28,234 over the period. Here is what the fixed-term contract pays on top when it ends, worked out by the site's engine.
| When the contract ends | Gross | Estimated net |
|---|---|---|
| End-of-contract bonus (10%) | €3,600 | €2,850 |
| Holiday pay (25 working days) | €3,960 | €3,135 |
| Total at the end of the CDD | €7,560 | €5,984 |
Calculation: bonus and holiday pay by the site's rules (holiday pay on gross including the bonus, or salary maintenance if higher), net estimated by the modele-social publicodes engine, before tax. Read it carefully: holiday pay is not a bonus, it replaces the holiday you did not take; on a permanent contract you would have taken it while still being paid. The real extra of the fixed-term contract is the bonus. The end-of-contract bonus calculator redoes this for your pay and contract length.
The bonus can drop to 6% if a collective agreement provides for it, with training commitments, and it is not owed in several cases: a permanent contract straight after, serious misconduct, seasonal or customary contracts, a young person's holiday job. The guide on the end-of-contract bonus details its basis and exclusions.
On a permanent contract, either side can end it by following a procedure: resignation with notice, dismissal for a stated reason, or mutual termination by agreement. A fixed-term contract, by contrast, is meant to run to its end. After the probation period, during which either side can end it without giving a reason, it can only be ended before the planned date by agreement of both sides, for serious misconduct, force majeure, unfitness for work certified by the occupational doctor, or because you are hired on a permanent contract elsewhere.
In that last case, you owe notice of 1 working day per week of contract, up to 2 weeks, unless the employer lets you go sooner. If it is the employer who ends it without an accepted reason, it owes you at least the salary up to the planned end date. Notice periods on a permanent contract are in the guide on the notice period.
A temp's assignment contract works much like a fixed-term contract, with the temping agency as employer: pay at least equal to that of an employee of the client company in the same job, an end-of-assignment payment on the same principle and at the same minimum rate as the fixed-term bonus, and holiday pay for every assignment, however short. Agencies also offer permanent temping contracts, a different status that guarantees pay between assignments.
Banks and landlords often look at the type of contract before granting a loan or a flat: this is not a legal rule, and each sets its own criteria. A well-paid fixed-term job can still be worth more than a cut-price permanent one: what counts is the pay, the role and what it does for what comes next. In both cases, pay is negotiated the same way (negotiating a job offer), and the contract is read before signing: reason, end date, renewal clause, probation. The guide employment contract: the clauses to check gives the full list.
No, not for the same job: a fixed-term employee's pay cannot be lower than that of a permanent employee with an equivalent qualification doing the same work in the company. Bonuses and benefits tied to the job follow the same rule. Nothing stops you from negotiating more, though, especially for a short, urgent assignment.
Yes, if you accept it and the permanent contract follows straight on: the bonus is only owed when the working relationship stops. In the guide's example, it is worth €3,600 gross. Holiday pay is still owed for the days not taken. If you turn down a permanent contract for the same or a similar job at no lower pay, you also lose the bonus, and 2 refusals within 12 months can cost you unemployment benefit.
Not in the way you would from a permanent job: after the probation period, a fixed-term contract can only be ended early in limited cases, including being hired on a permanent contract elsewhere or the employer agreeing. Leaving without an accepted reason exposes you to paying the employer damages. The guide on notice periods details the notice owed when you leave for a permanent job.
You keep it when the work continues without a break: if the contract carries on past its end date, it becomes a permanent contract with the service already built up. And if you are hired on a permanent contract when the fixed-term one ends, the length of the fixed-term contract is deducted from the new contract's probation period.
This guide gives you a method, not legal advice: the official rules and amounts are those of the sources above, as at their date.
