Gross / net calculator France
Estimate your net salary in France from a gross figure: the breakdown of employee contributions, the CSG and CRDS, the taxable net and the prelevement à la source, for a cadre as for a non-cadre. Contributions run roughly 21 to 23 % of the gross, with the CSG computed on 98.25 % of it. A salary is a private figure, so the calculation stays on your device.

In France, a private-sector employee bears roughly 21 to 23 % of employee social contributions on gross: old-age insurance, the Agirc-Arrco supplementary pension, balance contributions, then the CSG and CRDS levied on 98.25 % of the salary. The result is the net to pay before income tax; the withholding then applies to the taxable net, which is slightly higher because it adds back the non-deductible CSG and the CRDS.
The social security ceiling splits the salary into two bands with different rates. Counter-intuitive detail: the band above the ceiling is slightly less loaded on the employee side, because it escapes the 6.90 % capped old-age contribution. This calculator shows each contribution with its base and rate, for both executive and non-executive staff.

Frequently asked questions
What is the difference between net to pay, taxable net and social net?
The net to pay before tax is what the employer pays before income withholding. The taxable net, higher, is the basis for income tax: it adds back the non-deductible CSG and the CRDS. The social net, introduced in 2023, is the income retained for computing social benefits and follows yet other rules.
Where do I find my withholding rate?
It appears on your payslip and in your personal space on impots.gouv.fr, under “Manage my income tax withholding”. Left at 0 in the tool, the calculation stops at the pre-tax net.
Does an executive pay much more in contributions?
On the employee side, barely: only the 0.024 % APEC contribution is added. It is the employer contributions and the supplementary cover that truly distinguish the executive status. The net gap between executive and non-executive at equal gross is therefore minimal.
Does the calculation take my health insurance and bonuses into account?
You can enter the employee share of your health insurance. In contrast, bonuses, exempt overtime, meal vouchers and in-kind benefits are not modelled: only your payslip is authoritative.
