How It Works

5. Medicare = Gross × 1.45%
6. Convert annual taxes back to your pay period
Example Calculation
Monthly gross pay of $5,000 (Single):
Annual gross: $5,000 × 12 = $60,000
Taxable income: $60,000 - $15,000 = $45,000
Federal tax (annual): ~$4,740 → Monthly: ~$395
Social Security: $5,000 × 6.2% = $310
Medicare: $5,000 × 1.45% = $72.50
Net pay: ~$4,222.50
