Take-Home Pay Calculation Method
Your net income or take-home pay is calculated by subtracting all taxes and contributions from your gross salary:
Net Income Formula
\( \text{Net Income} = \text{Gross Salary} - \text{Social Security} - \text{Federal Tax} - \text{Regional Surcharge} \)
Where:
• Gross Salary = Your total annual income
• Social Security = 13.07% on gross
• Federal Tax = 25%-50% progressive on taxable income
• Regional Surcharge = 8%-25% of federal tax
Where:
• Gross Salary = Your total annual income
• Social Security = 13.07% on gross
• Federal Tax = 25%-50% progressive on taxable income
• Regional Surcharge = 8%-25% of federal tax
Effective Tax Rate
Your effective tax rate is your total tax paid divided by your gross income, typically lower than marginal tax rate due to progressive brackets:
Tax Rate Formulas
\( \text{Effective Tax Rate} = \frac{\text{Federal Tax + Regional Surcharge}}{\text{Gross Income}} \times 100\% \)
\( \text{Total Effective Rate} = \frac{\text{All Taxes + Social Security}}{\text{Gross Income}} \times 100\% \)
\( \text{Total Effective Rate} = \frac{\text{All Taxes + Social Security}}{\text{Gross Income}} \times 100\% \)
