Salary Calculation Methodolog

The calculator uses IRS-approved math:

Net Pay = (Base Salary + Benefits) − [(Total Income × Tax Rate) + Deductions]  

Example:

• $60,000 annual salary ($5,000/month)
• $200/month 401(k) match
• 24% effective tax rate
• $150 health insurance deduction

Gross Salary = $5,000 + $200 = $5,200  
Deductions = ($5,200 × 0.24) + $150 = $1,398  
Net Salary = $5,200 − $1,398 = $3,802  

This matches the methodology used by ADP and Paychex payroll systems.
