Example Calculation

Example:

  • Gross Pay: $4,000 per month
  • Filing Status: Single
  • Federal Allowances: 1
  • Missouri State Allowances: 1
  • Pre-tax deductions: $200 (401k contribution)

Step 1: Calculate Federal Tax (approx.)

  • Federal withholding = $4,000 × 12% ≈ $480

Step 2: Calculate Missouri State Tax

  • Missouri withholding ≈ $4,000 × 5.4% ≈ $216

Step 3: Social Security & Medicare

  • Social Security = $4,000 × 6.2% = $248
  • Medicare = $4,000 × 1.45% = $58

Step 4: Subtract deductions NetPay=4000−(480+216+248+58+200)≈2,798Net Pay = 4000 – (480 + 216 + 248 + 58 + 200) \approx 2,798NetPay=4000−(480+216+248+58+200)≈2,798
