Example: Stock Capital Gains Calculation
Scenario:
- Purchase Price: $50/share
- Sale Price: $75/share
- Number of Shares: 100
- Holding Period: Long-term (2 years)
- Filing Status: Single
- State Tax Rate: 9.3% (California)
Calculation:
- Gain per Share: $75 – $50 = $25
- Total Gain: $25 × 100 = $2,500
- Federal Tax (long-term approx. 15%): $2,500 × 0.15 = $375
- State Tax: $2,500 × 0.093 = $232.50
- Net Profit: $2,500 – ($375 + $232.50) = $1,892.50
