Practical guide
Gross pay is only part of the bill: the employer adds its own contributions, takes off the general reduction on low wages, and pays other costs that no payslip shows. The full calculation, with examples worked out by the site.
When a company hires, it thinks neither in net nor even in gross pay: it thinks in total cost. Between the gross salary written in the contract and what the hire really costs, there are employer contributions, a reduction that sharply lightens low wages, and a series of costs that appear on no payslip. This guide rebuilds that cost from examples calculated by the site's engine, whether you are an employer, an HR manager or a candidate who wants to understand the room on the other side of the table.
Non-cadre employee on a permanent full-time contract, €3,000 gross a month, company with fewer than 5 employees, standard company health cover, outside Alsace-Moselle. Employer contributions are grouped by family; the line-by-line detail, with the employee share alongside, is in the guide to employee contributions.
| Item | Per month | What it covers |
|---|---|---|
| Gross salary | €3,000 | What the contract provides, before the employee's contributions |
| + Health | €410 | Health insurance (paid by the employer alone) and its share of the mutuelle |
| + Pension | €500 | Capped and uncapped basic pension, Agirc-Arrco supplementary pension, CEG |
| + Unemployment | €128 | Unemployment insurance and wage guarantee (AGS) |
| + Family | €158 | Family allowances |
| + Work accidents | €62 | A rate specific to each company, depending on its risks |
| + Other | €49 | Housing aid (FNAL), autonomy, training, apprenticeship tax, social dialogue |
| − General reduction | €300 | Relief on employer contributions, larger the lower the salary |
| Total employer cost | €4,007 | That is €48,086 a year, and 33.6% more than gross pay |
Monthly amounts read from the modele-social publicodes engine (2026 rates), to the nearest euro. The employee receives €2,353 net before tax: each euro of net pay costs the employer €1.70.
Pensions weigh the most: the employer pays into the basic scheme and Agirc-Arrco, like the employee but at higher rates. Next comes health: health insurance no longer has an employee share outside Alsace-Moselle, so the employer pays it alone, and it funds at least 50% of the mutuelle (see the guide to company health cover). Unemployment insurance, family allowances and work accidents exist only on the employer's side: they play no part in working out net pay, but they protect the employee. The work-accident rate varies from one company to another depending on its activity and its claims record; the engine applies a default rate.
Since January 2026, the relief on employer contributions has been called the single degressive general reduction (RGDU). It is at its highest at the SMIC, shrinks as pay rises and stops at 3 times the SMIC. For the whole of 2026, the SMIC used for this calculation remains January's (€1,823.03 gross a month), which puts the exit point at around €5,469 gross a month for a full-time job. As a result, total cost does not track gross pay line for line, as the table shows.
| Gross a month | General reduction | Total cost | Above gross | Cost of one net euro |
|---|---|---|---|---|
| €1,867 (SMIC) | €700 | €1,988 | 6.5% | €1.37 |
| €2,200 | €539 | €2,625 | 19.3% | €1.53 |
| €3,000 | €300 | €4,007 | 33.6% | €1.70 |
| €4,000 | €158 | €5,578 | 39.4% | €1.77 |
| €5,000 | €109 | €7,065 | 41.3% | €1.79 |
The table follows this rule: the reduction is worked out with January's SMIC, for the same pay every month of the year. Pay at today's SMIC therefore no longer gets quite the maximum reduction.
A few contributions depend on headcount: housing aid, vocational training, the forfait social on the employer's share of health cover, sometimes the transport levy depending on the town, and the general reduction itself, slightly larger above a certain headcount. For the same gross pay of €3,000, the engine works out €4,007 a month in a company with fewer than 5 employees and €4,057 in one with 250 employees or more. The gap is real, but small next to gross pay itself.
The calculated employer cost stops at payroll. Depending on the company, a hire also costs:
An employer often starts from a budget. With €4,000 a month all-in, the engine finds a gross salary of €2,996, i.e. €2,349 net for the employee. The employer cost tool runs this calculation both ways, with the headcount, cadre status and health cover of your choice.
For a candidate, this calculation explains two things. First, asking for a few hundred euros more gross a month means more to the company, which thinks in annual cost: talk in gross annual terms, as the guide to negotiating your starting salary recommends. Second, at equal cost not everything is worth the same: a meal voucher or better-funded health cover can cost the employer less than a gross pay rise for a similar gain, which is why it helps to compare offers on net pay with the job offer comparison tool. And to know which gross figure to aim for, the CV analysis estimates what you are worth on the market.
For a full-time job on the SMIC, i.e. €1,867.02 gross a month, the site's engine works out a total cost of €1,988 a month for a small company: the general reduction (€700) wipes out most employer contributions at that level. The gap between gross pay and total cost is smallest at the minimum wage.
Not quite. For €3,000 gross a month, every euro of net pay costs the employer €1.70 according to the site's engine, and less near the minimum wage. The gap widens as pay rises, because the general reduction shrinks and then disappears, but it stays well short of double on an ordinary salary. Below 3 times the SMIC, an extra euro of net pay from a rise costs more: see the next question.
Yes. A 3% rise on €3,000 gross adds €71 of net pay a month and costs the employer €147 more, according to the site's engine: €2.06 for each euro of net pay gained. Near low wages the gap is even wider: every extra euro of gross pay also shrinks the general reduction.
The employer's share of health cover, yes: the site's calculation includes it with a standard contract. Meal vouchers, no: their employer share adds to the cost but is not counted in the tool. Commuting, training beyond compulsory contributions, equipment and recruitment are not counted either.
