How to calculate stock profit and loss?
To calculate your stock profit or loss, subtract your purchase price from your selling price. Then times the number of shares. Then subtract the buy commission and sell commission. If the result is positive, it’s a profit. If it’s negative, it’s a loss.
For example, if you buy 100 shares of a stock at $100 per share and sell them at $120 per share, and the buy commission is $10 and the sell commission is $10, then your profit is $1980.
