Capital Gains Tax Estimator
How to Use This Tool
Enter the purchase price and sale price of your investment, select the asset type, and specify how long you held it. Input your federal tax bracket and optional state tax rate, then click Calculate Tax. Use the Reset button to clear all fields and start over.
Formula and Logic
Capital gain = Sale price - Purchase price. Federal tax is calculated by applying your income tax rate to the gain, with a 30% discount for long-term holdings. State tax is applied separately based on your entered rate. Total tax is the sum of federal and state taxes, and net proceeds are the sale price minus total tax.
Practical Notes
- Short-term gains are taxed at your ordinary income rate, which can be significantly higher than long-term rates.
- Long-term capital gains benefit from reduced tax rates (0%, 15%, or 20% depending on income), but this tool uses a simplified model for estimation.
- Consider tax-loss harvesting to offset gains, especially near year-end.
- State taxes vary widely; always check your local regulations for accurate planning.
- Keep records of purchase dates and cost basis for accurate reporting.
Why This Tool Is Useful

How accurate are the tax estimates?
This tool provides a simplified estimation based on common tax rules. Actual taxes depend on your specific situation, including deductions, credits, and other income. Use it for planning, not for filing.
