How to use the Stock profit calculator
Enter buy price per share, sell price per share, number of shares, and total trading fees. Choose the currency for your inputs and read the result as you change the values.
How it works and formula
Net gain = (selling price per share − buying price per share) × shares − total fees.
Worked example
| Buy price per share | 40 |
|---|---|
| Sell price per share | 52 |
| Number of shares | 10 |
| Total trading fees | 5 |
Result
Net gain or loss $115.00
Choosing your inputs
Use average per-share prices for the same quantity of shares and enter trading fees from both sides of the trade. Enter all figures in one currency. For multiple purchases, use a share-weighted average buy price.
How to interpret the result
Ten shares bought at $40 and sold at $52 generate $120 before fees. With $5 in fees, the gain is $115. Selling at $40 instead leaves a $5 loss. A negative result means sale proceeds fell short of purchase cost and fees.
Frequently asked questions
What should I enter for fees?
Combine the purchase and sale fees for the trade. The calculation excludes dividends and taxes.
How do I find the break-even sale price?
Divide total trading fees by shares sold and add the result to the purchase price per share. In the worked example, break-even is $40.50.
