Capital Gains Tax Calculator
Enter your own rate to see what a sale leaves you after tax.
Method
How it works
Purchase price, sale price and quantity determine the gain before tax. Tax is applied at the user-entered rate only when that gain is positive, and net gain subtracts the calculated tax.
The result is a simplified estimate using one tax rate. It does not apply country-specific allowances, holding periods, loss offsets, transaction fees or different tax lots.

Which capital gains tax rate does it use?

Are brokerage fees included in the taxable gain?
No. Gain is calculated from purchase price, sale price and quantity only.
