Understanding how much you’ll actually receive at the end of the month is essential for your financial planning. Net salary is the amount that reaches your account after all mandatory deductions.

Many workers get confused when they see the difference between the value promised during hiring and what they actually receive. This difference can reach 20% or more of the gross salary, depending on the salary range.

What is net salary

Net salary is the final amount you receive after deducting all mandatory deductions required by law. It’s the money that’s actually available for your monthly expenses.

Difference between gross and net salary

Gross salary is the total amount agreed upon in your employment contract, before any deductions. Net salary is what remains after INSS (social security), Income Tax and other charges are deducted.

Example: Gross salary of R$ 5,000 → deductions of R$ 1,100 → net salary of R$ 3,900

The difference between gross and net varies according to your salary range:

  • Salaries up to R$ 2,640: lower deduction (INSS only)
  • Salaries above R$ 2,640: higher deduction (INSS + IRPF)
  • Salaries above R$ 7,087: maximum deduction percentage

Importance of correct calculation

Knowing your actual net salary is essential to:

  • Plan your monthly family budget
  • Negotiate salary increases consciously
  • Compare job offers appropriately
  • Identify errors in your payroll

Mandatory salary deductions

The main deductions that apply to your salary are determined by federal law. Each has specific rules and percentages for 2024.

INSS - 2024 rates

INSS (social security) deduction follows a progressive table, where each salary range has a different rate:

Salary RangeRate
Up to R$ 1,412.007.5%
R$ 1,412.01 to R$ 2,666.689%
R$ 2,666.69 to R$ 4,000.0312%
R$ 4,000.04 to R$ 7,786.0214%

The maximum contribution ceiling in 2024 is R$ 908.85.

Example: Salary of R$ 3,500 → INSS of R$ 311.82 (progressive calculation)

IRPF - updated table

Income Tax (IRPF - income tax) applies to salary after INSS deduction. The calculation base is gross salary minus INSS.

Income RangeRateDeduction
Up to R$ 2,259.20ExemptR$ 0
R$ 2,259.21 to R$ 2,826.657.5%R$ 169.44
R$ 2,826.66 to R$ 3,751.0515%R$ 381.44
R$ 3,751.06 to R$ 4,664.6822.5%R$ 662.77
Above R$ 4,664.6827.5%R$ 896.00

FGTS and other deductions

FGTS (severance fund): 8% of gross salary (not deducted from the worker - paid by the employer)

Other possible deductions:

  • Meal or food vouchers
  • Health insurance (when there’s employee participation)
  • Group life insurance
  • Union contribution (when applicable)

How to calculate net salary step by step

The calculation follows a specific sequence that must be respected to reach the correct value.

Step 1: Calculate INSS

Apply progressive rates to each salary range:

Practical example: Salary of R$ 4,500

  • Range 1: R$ 1,412 × 7.5% = R$ 105.90
  • Range 2: R$ 1,254.68 × 9% = R$ 112.92
  • Range 3: R$ 1,333.35 × 12% = R$ 160.00
  • Range 4: R$ 499.97 × 14% = R$ 70.00
  • Total INSS: R$ 448.82

Step 2: Calculate IRPF base

Subtract INSS from gross salary:

IRPF base = R$ 4,500 - R$ 448.82 = R$ 4,051.18

Step 3: Calculate IRPF

With the base of R$ 4,051.18, apply the table:

IRPF = (R$ 4,051.18 × 22.5%) - R$ 662.77 = R$ 248.74

Step 4: Final result

Net salary = R$ 4,500 - R$ 448.82 - R$ 248.74 = R$ 3,802.44

Special cases

Dependents: Each dependent reduces R$ 189.59 from the IRPF base.

Alimony: Can be fully deducted from the IRPF base.

Medical expenses: Unlimited deduction when proven.
