Capital Gains Tax Calculator

The gain is your net proceeds minus your cost basis. Cost basis is the purchase price per unit times the quantity, plus any buy fees. Net proceeds is the sale price per unit times the quantity, minus any sell fees. If proceeds are higher than basis you have a gain; if lower, a loss.

Enter the capital gains rate that applies to your situation. Most tax systems tax long-term gains (assets held past a threshold, often a year) at a lower rate than short-term gains, which may be taxed like ordinary income. This tool does not pick the rate for you — check your country's rules or a tax professional.

If your net proceeds are below your cost basis, the result shows a capital loss and the estimated tax is zero, because you don't owe gains tax on a loss. Many tax systems let you deduct losses against other gains or carry them forward, but this tool does not model those offsets.

No. It's a general, browser-based estimate that multiplies your gain by the rate you supply. It ignores exemptions, allowances, holding-period rules, surtaxes, and state or local taxes. Always confirm the numbers with your tax authority or a qualified advisor before filing.
