If I buy a stock for 10 dollars a share and I sell at 20 dollars a share, how much are my capital gains?

Answer 1

The first 2 responders got it correct. The 3rd no-name responder is wrong. 100 shares X $10 + $7 commission = cost basis of $1,007.00. Sell 100 X $20 - (minus) = $1993 (net selling cost). Capital gains $1993.00 - $1007.00 = $986 net capital gains.

Answer 2

Hi Mel,
Your capital gains would be the difference of $20 what you sold the share for minus the $10 per share that you paid minus the commissions/expenses that you had to pay to purchase each share minus the commission/expenses that you had to pay to sell the share multiplied by the number of shares.
I am sure you are aware of the concept of short term capital gains and long term capital gains. If you held the shares for over a year the capital gain is considered long term and you will be taxed at a lower rate. If you held the shares for less than a year, the capital gain is considered short term and will be taxed at a higher rate.
I am not a tax accountant, cpa or other financial professional but these are the basics. Best regards!

Answer 3

Assuming that you include any transaction costs (i.e. commissions) in specifying purchase and sales prices, the capital gain would be $10 per share.

(Capital gain = Sales price - Basis)
