Formula Used in ADP NJ Paycheck Calculator
This calculator uses a simplified payroll tax formula based on taxable income.
Step 1: Calculate Taxable Income
TaxableIncome=GrossPay−Pre-TaxDeductions
If deductions exceed gross pay, taxable income is set to zero.
Step 2: Federal Tax Calculation
FederalTax=TaxableIncome×(FederalRate÷100)
Step 3: New Jersey State Tax
StateTax=TaxableIncome×(StateRate÷100)
Step 4: Social Security Tax
SocialSecurity=TaxableIncome×6.2%
Step 5: Medicare Tax
Medicare=TaxableIncome×1.45%
Step 6: Total Tax
TotalTax=Federal+State+SocialSecurity+Medicare
Step 7: Net Pay
NetPay=TaxableIncome−TotalTax
Example Calculation
Let’s understand with a real-world example.
Input Values:
- Gross Pay: $5,000
- Pre-Tax Deductions: $500
- Federal Tax: 12%
- State Tax (NJ): 5%
Step 1: Taxable Income
5000−500=4500
Step 2: Taxes
- Federal Tax = 4500 × 12% = $540
- State Tax = 4500 × 5% = $225
- Social Security = 4500 × 6.2% = $279
- Medicare = 4500 × 1.45% = $65.25
Step 3: Total Tax
540+225+279+65.25=1109.25
Step 4: Net Pay
4500−1109.25=3390.75
Final Result:
- Net Pay: $3,390.75
- Total Taxes: $1,109.25
This shows how significantly taxes reduce take-home income.
