Salarié income tax, CSG/CRDS, assurance vieillesse, and retraite complémentaire AGIRC-ARRCO (single filer, 1 part). Models the barème progressif, CSG/CRDS, and the two other cotisations salariales that apply to every private-sector payslip. Does not model mutuelle/prévoyance (rate set by each employer's own collective agreement, not a single national rate), the quotient familial for couples/dependents, or auto-entrepreneur status.

Contract median

≈ 124 300 € gross a year
At a median 565 €/day, contract work grosses about 124 300 € a year over 220 billable days, 94% more than the 64 000 € permanent median. That premium has to pay for what an employer would otherwise cover: paid holiday and sick days, pension contributions, and the gaps between contracts.
Contract and permanent benchmarks come from separate samples, so treat the gap as a guide rather than a like-for-like quote. See Smart Contract / Solidity Developer contract rates and contractor take-home →
