How to Calculate Net Salary: 2025 Complete Guide
Learn how to calculate your net salary with updated 2025 INSS and income tax tables. Step-by-step examples and practical calculator.
Understanding exactly how much you’ll receive at the end of the month is essential for financial planning. Your net salary is the amount that actually lands in your account after all mandatory deductions.
With updates to INSS (social security) and Income Tax tables for 2025, it’s important to know the new values to correctly calculate your compensation. Let’s show you how to do this calculation in a practical and accurate way.
What is net salary
Net salary is the final amount you receive after applying all legal deductions to your gross salary. It’s literally the money that becomes available in your bank account.
Difference between gross and net salary
Gross salary is the total amount agreed upon in the employment contract, before any deductions. Net salary is what remains after mandatory deductions.
The difference between them can vary from 8% to 27.5% of gross salary, depending on the salary range and benefits used.
Example: Gross salary of R$ 5,000 → deductions of R$ 1,120 → net salary of R$ 3,880
Why calculate net salary
Knowing your net salary allows for:
- More precise financial planning
- Salary negotiations based on real values
- Monthly budget control
- Verification that deductions are correct
Mandatory deductions in 2025
The main deductions that reduce gross salary are INSS (social security), Income Tax, and transportation vouchers. Each has specific calculation rules.
INSS - updated table
INSS (social security) contribution in 2025 follows the progressive table, with rates from 7.5% to 14%:

| R$ 3,856.95 to R$ 7,786.02 | 14% | Maximum R$ 550.03 |
The contribution ceiling is R$ 908.85 for salaries above R$ 7,786.02.
IRPF - deduction brackets
Income Tax is applied to salary after INSS (social security) deduction, with rates from 0% to 27.5%:
| Salary Range | Rate | Deduction |
|---|---|---|
| Up to R$ 2,259.20 | Exempt | - |
| R$ 2,259.21 to R$ 2,826.65 | 7.5% | R$ 169.44 |
| R$ 2,826.66 to R$ 3,751.05 | 15% | R$ 381.44 |
| R$ 3,751.06 to R$ 4,664.68 | 22.5% | R$ 662.77 |
| Above R$ 4,664.68 | 27.5% | R$ 896.00 |
Each dependent entitles you to a deduction of R$ 189.59 per month.
Transportation voucher
Transportation voucher deduction is limited to 6% of gross salary. If the required amount is less than 6%, only the actual transportation cost is deducted.
Employees can choose not to use the benefit if they prefer to cover their own transportation costs.
How to calculate net salary step by step
The calculation follows a specific sequence to correctly apply the percentages for each mandatory deduction.
Practical example with CLT
Let’s calculate the net salary for a CLT (labor law) employee with a gross salary of R$ 4,500:
Step 1: Calculate INSS
- Up to R$ 1,518.00: R$ 113.85
- From R$ 1,518.01 to R$ 2,571.29: R$ 94.79
- From R$ 2,571.30 to R$ 3,856.94: R$ 154.28
- From R$ 3,856.95 to R$ 4,500.00: R$ 90.03
- Total INSS: R$ 452.95
Step 2: Base for IRPF
- R$ 4,500.00 - R$ 452.95 = R$ 4,047.05
Step 3: Calculate IRPF
- 22.5% bracket: (R$ 4,047.05 × 22.5%) - R$ 662.77 = R$ 248.81
Step 4: Net salary
- R$ 4,500.00 - R$ 452.95 - R$ 248.81 = R$ 3,798.24
