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).
