What's the difference between CNAS and CASNOS?

CNAS covers salaried employees (employee and employer), while CASNOS covers the self-employed: merchants, craftspeople, freelancers and auto-entrepreneurs. The rates and calculation method are entirely different.

What's the difference between CNAC unemployment insurance and the unemployment allowance?

CNAC's indemnity targets employees who lost a permanent job for economic reasons after at least 3 years of contributions, calculated on salary. The unemployment allowance (employment category) targets first-time job seekers with a fixed amount.

Is joining the social mutual mandatory?

No, it is optional and supplementary to mandatory social security (CNAS or CASNOS), for additional coverage.

Understand CNAS social security contributions in Algeria: employee share, employer share and total cost.

Guide to social-security calculators in Algeria

Algerian social security has two schemes: CNAS for salaried employees (9% employee share, 26% employer share) and CASNOS for the self-employed (15% of the annual base). This category covers the contributions themselves, then the rights they open up: retirement, disability, death capital, 150-day maternity leave, work-accident annuity, CNAC compensation for economic layoffs, and the late-payment penalty on CASNOS contributions. Each calculator handles one branch of these rights depending on your scheme (employee or self-employed).

What are the numbers based on?

Contributions and their rates come from the 2026 Finance Law (CNAS) and the official CASNOS portal. The associated rights rest on dedicated laws: maternity leave on law 25-08, the work-accident annuity on law 83-13, CNAC's unemployment indemnity on legislative decrees 94-09/10/11, and the social mutual on law 15-02.
