Practical guide
Target bonuses, commission, seniority pay, one-off bonuses: part of a salary can move from one year to the next. This guide says which bonuses are owed, what the contract must spell out, what is left after deductions, and why you negotiate the base first.
In a job offer or on a payslip, pay often splits into several pieces: a base salary, variable pay linked to targets, and bonuses that are more or less regular. They are not all worth the same. Some are guaranteed; others depend on your results, the company's results or the employer's goodwill. This guide helps you sort them out, know what must be in writing, and compare two offers that mix base and variable pay in different proportions.
The base salary is the contract's basic pay, paid every month whatever happens. Variable pay depends on performance: individual or team targets, revenue, margin, number of deals signed. Bonuses are sums paid on top of salary, at regular intervals or not: thirteenth month, holiday bonus, seniority bonus, one-off bonus. Profit-sharing schemes (intéressement and participation) are not salary: they have their own rules, described in the guide to profit-sharing schemes.
A bonus is compulsory when it is provided for by the employment contract, the collective agreement or a company agreement, a company custom (paid to everyone or to one category, regularly, on a fixed calculation) or an employer commitment. In every other case it is a gratuity: the employer decides each time, and it is not part of the pay you are owed. A “usual” bonus that was never written down can therefore be a right or a mere favour; it all turns on the three tests of a custom given above.
Badly worded variable pay is a classic source of disputes. Before you sign, check that the contract or its yearly addendum answers these questions:
Bonuses, commission and gratuities count as pay subject to contributions, and as taxable salary. A bonus of €2,000 gross, paid on top of a €3,000 monthly salary, gives €1,583 net before tax and €1,640 of taxable pay, according to the site's engine. The notable exception is the value-sharing bonus, which can be exempt under conditions but cannot replace a pay rise. To see what a rise in base pay would give instead, the pay rise simulator works out the net gain month by month.
Offer A: €3,000 gross a month, no variable pay. Offer B: €2,800 gross a month and a target annual variable of €3,000. On paper, B pays more. In net annual terms, worked out by the site, it all depends on how much of the variable is actually paid:
| Variable paid | B gross a year | B net a year | A net a year | Better offer |
|---|---|---|---|---|
| 100% | €36,600 | €28,709 | €28,234 | B |
| 50% | €35,100 | €27,522 | €28,234 | A |
| 0% | €33,600 | €26,334 | €28,234 | A |
Offer A stays at €36,000 gross a year whatever happens. To run this calculation with your own two offers (status, months paid, meal vouchers, health cover), use the job offer comparison tool, and to read a job ad that mixes base and variable pay, the guide to reading a job ad.
The base salary is the only guaranteed part, the one future pay rises build on, the one a bank or a landlord looks at, and the one that counts first when you next change jobs. Negotiate it first, in gross annual terms; variable pay comes after, as a top-up. If the employer cannot move on the base, ask for guaranteed variable pay in the first year, written and achievable targets, or a pro rata share if you leave. The full method is in the guide to negotiating your starting salary, and the CV analysis gives you a starting figure: what you are worth on the market.
Roughly the same share as salary, slightly more in fact, because health cover is not deducted a second time. For a bonus of €2,000 gross paid to an employee on €3,000 a month, the site's engine works out €1,583 net before tax. Income tax then comes off at your withholding rate.
It depends on where it comes from. A bonus in your contract cannot be withdrawn without your agreement; a bonus in the collective agreement is binding while the agreement applies; a bonus that comes from a custom can be withdrawn, with written notice to each employee and to staff representatives and a notice period; a discretionary bonus, decided case by case, is never owed from one year to the next.
Not always, and it is the first question to ask. A “package” often adds the base salary and target variable pay together, whereas only the base is guaranteed. Ask for the breakdown: annual base, target variable pay, what was actually paid in recent years, and the conditions of payment.
No. It is optional, can be exempt from contributions and income tax under conditions, and can replace neither a pay rise nor a bonus provided for by an agreement, the contract or a custom. Its treatment depends on the payment date, the size of the company and your salary: the official page listed in the sources is the reference.
