How it Works
The Brazilian National Social Security Institute (INSS) is the social security system that provides retirement, disability, and other benefits to workers. In 2025, contributions follow a progressive model with four brackets ranging from 7.5% to 14%, with a ceiling of R$8,157.41.
The progressive system, implemented in 2020, works similarly to income tax: each salary bracket is taxed at its own rate. This especially benefits lower-income workers who pay proportionally less than under the previous flat-rate system.
The effective INSS rate is always lower than the nominal rate of the highest bracket reached. For example, a worker earning R$5,000 does not pay 14% on the total but a combination of all four rates, resulting in an effective rate of around 9.8%.
Use this calculator to determine the exact amount of your INSS contribution, understand how each bracket impacts the total deduction, and plan your monthly budget considering social security.
