How the 13th salary is paid
The 1st installment (by Nov 30) is a 50% advance with no deductions. The 2nd installment (by Dec 20) pays the rest, applying INSS and income-tax deductions over the full amount.
Proportionality and deductions
A full year earns the full 13th; fewer months earn it proportionally (1/12 per month). Deductions follow the current INSS and income tax tables.
How to use
Enter the gross salary, the number of months worked in the year, the number of dependents and which installment to calculate (1st, 2nd or full). The calculator applies the proportionality and the INSS and income-tax deductions and shows the net amount you will receive.
Frequently asked questions

It is a close estimate using current INSS and income-tax tables; small differences may apply.
