Four separate contributions sit on top of a Brazilian CLT salary, and none of them mirror the employee's own deductions the way a straightforward "match" would. INSS Patronal is a flat, uncapped percentage, genuinely different from the employee's own capped INSS. FGTS doesn't reduce anything on the employee's payslip at all, it's an entirely separate account-building mechanism. RAT/SAT and Sistema S are both 100% employer-funded, with no employee-side equivalent whatsoever.
What makes Brazilian hiring costs genuinely confusing in cross-country comparisons is the widely-cited "70-80% encargos sociais" figure. That number bundles this calculator's payroll-tax components together with vacation pay, its mandatory 1/3 bonus, and termination provisioning, categories this calculator deliberately keeps separate since they're economically different (time-off and termination costs, not recurring payroll contributions). The 30-40% range this calculator computes is the narrower, more directly comparable figure to what other markets' employer-cost calculators on this site show.
The 13th salary, décimo terceiro, is the one line here that IS a genuine recurring annual cash cost, reused directly from this site's dedicated calculator rather than recomputed, so the two numbers can never drift apart.
