💹 Stock Profit Calculator
Calculate the profit or loss on a stock trade after commissions, your percentage return, and the break-even selling price.
How the Stock Profit Calculator Works
The result of a stock trade is the difference between what you receive when you sell and what you paid to buy, minus any commissions on both trades. Many brokers now charge no commission on stock trades, but some charge a flat fee per trade; enter yours, or leave it at zero.
The calculator shows the net profit or loss, the return as a percentage of your total cost, and the break-even price — the selling price at which you would neither gain nor lose after commissions. It does not include dividends received while you held the shares, or taxes; capital gains tax depends on how long you held the shares and on the rules where you live.
Formula
Cost = shares × buy price + buy commission Proceeds = shares × sell price − sell commission Profit / loss = proceeds − cost Return (%) = profit ÷ cost × 100 Break-even price = (cost + sell commission) ÷ shares
How to Use It
- Enter the number of shares, the buy price, and the sell (or current) price.
- Enter the commission for the buy and the sell, if any.
- Read the profit or loss and the percentage return.
- Check the break-even price.
Frequently Asked Questions
How do I calculate profit on a stock?
Subtract what you paid (shares × buy price + commission) from what you receive (shares × sell price − commission). Divide the result by what you paid to get the percentage return.
What is the break-even price?
The selling price at which proceeds exactly cover the purchase cost and both commissions. With no commissions, it equals the buy price.
Are dividends included?
No. To see the income from dividends separately, use the dividend yield calculator.
Do I pay tax on stock profits?
In many countries, realized gains are taxable, often at different rates for short- and long-term holdings. Rules depend on your country and account type.
