Cost basis is the original price paid for shares of a security plus or minus certain adjustments required by applicable tax rules such as adjustments with respect to reinvested distributions and sales charges.
Calculate Cost Basis. Identify the total dollar value of all the shares you purchased. For example, if you purchased 100 shares at $20 each, the total dollar value is $2,000. Add the total commission fee to the total dollar value of the investment. This is the total cost basis.For example, if the transaction cost $5, the total cost basis of your investment is $2,005.or example, if your per-share cost basis is $20.05 and the stock now trades for $21, then your profit per share is 95 cents. If you own 100 shares, then you have a capital gain of $95.
