What goes into the calculation
The starting point is gross salary. Then come deductions such as INSS, IRRF base, dependents, alimony or benefits. In real payslips, other payroll events may change the final result.
- Use monthly gross salary as the base.
- Apply progressive INSS before IRRF.
- Review benefits and additional deductions separately.
When to use the calculator
Use the calculator to compare offers, plan a budget or check a payslip estimate. For official payroll closing, validate with HR, an accountant or payroll software.
The simulation is most useful when you separate gross salary, mandatory deductions and contract-specific adjustments.
