What the result means

The result is an estimate for planning. It highlights the gross amount, estimated tax burden, and after-tax amount so you can understand the practical impact before making a financial decision.

Capital gain = sale price - purchase price - selling costs. Tax = positive capital gain × tax rate. Net profit = capital gain - tax.

Tax laws vary by country, state, city, filing status, income type, holding period, and exemptions. Use this as a quick planning tool, not as formal tax advice.

Example calculation

If you bought an asset for $10,000, sold it for $15,000, paid $500 in selling costs, and use a 15% tax rate, the gain is $4,500 and estimated tax is $675.

Tips for better results

  • Include broker fees or closing costs as selling costs.
  • Use the rate that matches your expected holding-period treatment.
  • Compare sale-price scenarios before deciding when to sell.
