Calculate Brazilian insalubridade (10/20/40%) or periculosidade (30%) with reflexos.
Working exposed to agents harmful to health or to a life-threatening risk entitles you to a salary premium, but these are two different additionals, each with its own rules. The insalubridade (health-hazard) additional (CLT art. 192) pays for exposure to agents that harm health (noise, heat, chemical or biological agents) and is worth 10% (minimum grade), 20% (medium) or 40% (maximum) of the minimum wage. The periculosidade (danger) additional (CLT art. 193) pays for risk of death (electricity, flammables, explosives, security work) and is worth 30% of the base salary. The two cannot be combined (art. 193 §2): the worker takes the more advantageous one. This calculator runs both, flags the better one, and projects the reflexos on vacation, 13th salary and FGTS, always as an estimate, since characterization depends on a technical report.
Insalubridade looks at health: exposure to harmful agents above the NR-15 tolerance limits generates the additional, graded by risk intensity, 10%, 20% or 40%. STF Binding Precedent 4 bars the minimum wage as an index for a labor advantage, but it also bars the courts from creating a substitute on their own; so, absent a law or collective agreement setting a different base, case law keeps applying the minimum wage residually.
Periculosidade looks at life: high-risk activities (electricity, flammables, explosives, radiation, personal or property security), defined in NR-16, generate 30%, and here the base is the employee's base salary, excluding bonuses and prizes. Because the two do not stack, someone whose condition characterizes both receives only the more advantageous one.
Suppose a base salary of R$ 3,000 and a reference minimum wage of R$ 1,500. Medium-grade insalubridade: 20% of the minimum = R$ 300 a month. Periculosidade: 30% of the base salary = R$ 900 a month. If the condition characterized both, periculosidade would apply, far more advantageous in this case.
The math changes with the base. If a collective agreement sets insalubridade on the base salary (allowed by STF SV 4), the maximum grade (40% of R$ 3,000 = R$ 1,200) would overtake periculosidade. That is why the tool computes both and flags the better one, and projects that the habitual additional carries over into vacation, 13th salary and FGTS.
The right to the additional arises not from the worker's perception but from technical characterization: an expert report (based on the PPRA/PGR and the LTCAT) prepared by a qualified professional is required by NR-15 and NR-16 for administrative or judicial proof. Without the report, courts usually order an examination during the case.
The additional can also cease. Under TST Súmula 80 and CLT art. 191, supplying PPE that effectively neutralizes the harmful agent removes the right to the insalubridade additional; likewise, once the risk is eliminated, payment stops. For amounts unpaid in the past, the five-year statute of limitations on labor claims applies.

CLT art. 193 §2º: insalubridade e periculosidade são inacumuláveis, o empregado tem direito de optar pelo mais favorável. O TST consolidou esse entendimento no Tema Repetitivo (IRR) nº 17 (TST-RRAg-20516-37.2016.5.04.0004, DEJT 19/12/2024): a vedação vale mesmo quando os dois adicionais decorrem de fatos geradores distintos e autônomos.
CLT art. 192 (insalubridade medio 20% sobre Salário mínimo (R$ 1621.00, Portaria Interministerial MPS/MF nº 13/2026)). Base de cálculo: salario-minimo. SV 4 STF veda o salário mínimo como indexador, mas não autoriza o Judiciário a criar novo índice; por isso a jurisprudência o mantém residualmente até sobrevir lei ou norma coletiva.
