What is CSG and CRDS?

CSG (contribution sociale généralisée) and CRDS (contribution au remboursement de la dette sociale) are flat social levies. They apply to about 98.25 percent of gross salary, at roughly 9.2 percent for CSG and 0.5 percent for CRDS combined on that base.

What does AGIRC-ARRCO cover?

AGIRC-ARRCO is the mandatory supplementary pension scheme for private-sector employees. The employee share is around 3.15 percent on the first tranche of salary, with a higher rate on income above the social security ceiling.

What is the difference between cadre and non-cadre?

Cadre (managerial) status carries some additional contributions such as the APEC levy and a slightly different pension treatment. Non-cadre employees pay marginally less, which is why the tool asks for status.

Is this the same as net after tax?

No. This estimates net before income tax (net imposable / net à payer before prélèvement à la source). French income tax is withheld separately at source; use the income tax calculator for that part.

Is my salary data sent anywhere?

No. The whole calculation runs in your browser. Nothing is transmitted or stored.

France Cotisations Sociales Calculator

In France, an employee’s gross (brut) salary is reduced by a set of cotisations sociales — mandatory social contributions funding health, pensions, unemployment and the social debt — before they receive their net pay. This free calculator estimates the employee-side share so you can do a quick gross-to-net check. It runs entirely in your browser and is an estimate, not a payslip.

How it works

The tool applies the main employee-side contribution rates to the appropriate bases:

CSG / CRDS. Applied to about 98.25% of gross salary. CSG is roughly 9.2% (part deductible and non-deductible) and CRDS 0.5%.
Health, maternity, disability. A small employee share on gross.
Retraite (pension). Basic scheme plus AGIRC-ARRCO supplementary: about 3.15% on Tranche 1 (up to the monthly social security ceiling, the plafond, ~3,864 euros) and a higher rate on Tranche 2.
Chômage (unemployment). The employee share of the unemployment contribution.
Cadre extras. For cadres, the APEC contribution and related items are added.

Net = gross − the sum of these employee contributions (before income tax).

Example

For a non-cadre on 3,000 euros gross per month, the headline employee-side contributions in this tool come to roughly 13% of gross (CSG/CRDS dominates, plus the AGIRC-ARRCO pension share), leaving a net of around 2,600 euros — before the income tax withheld at source. Real payslips can run higher once prévoyance and company-specific charges are added.

Notes

Contribution rates vary by company agreement (convention collective), prévoyance plans, and year, and several have ceilings tied to the plafond de la Sécurité sociale (PMSS). This tool uses representative headline rates for an order-of-magnitude estimate. For an exact figure, rely on the official payslip or a certified paie tool. Everything runs locally.
