What Is a Stock Profit Calculator?
A Stock Profit Calculator estimates the profit or loss
produced by buying and selling shares at different
prices.
The calculator includes the purchase price, selling
price, number of shares, and transaction fees so you
can see both the gross price gain and the estimated
net trading result.
It also calculates return on investment, percentage
price change, profit per share, total fees, and the
approximate break-even selling price.
How the Stock Profit Calculator Works

and buying commission.

selling or transaction fees.

Stock Purchase Cost
Total Purchase Cost =
(Buy Price × Number of Shares) + Buy Fee
Net Sale Proceeds
Net Sale Proceeds =
(Sell Price × Number of Shares) − Sell Fee
Stock Profit Formula
Net Profit / Loss =
Net Sale Proceeds − Total Purchase Cost − Other Fees
Stock ROI Formula
ROI =
Net Profit ÷ Total Purchase Cost × 100
Stock Profit Calculation Example
Suppose you purchase
50 shares at $100 each
and later sell those shares for
$125 each.
Buy Price:
$100 per share
Sell Price:
$125 per share
Shares:
50
Purchase Value:
$5,000
Gross Sale Value:
$6,250
Gross Price Gain:
$1,250
Trading fees are then deducted to determine the
estimated net profit and actual return on the money
used to purchase the shares.
Gross Stock Profit vs. Net Stock Profit
Gross Profit
Gross profit looks only at the difference between the
buying price and selling price multiplied by the
number of shares.
Net Profit
Net profit also accounts for buying commissions,
selling commissions, and other transaction fees.
Net profit therefore provides a more useful estimate
of the financial result of the trade before any
applicable taxes.
What Is the Break-Even Stock Price?
The break-even stock price is the approximate selling
price per share required for your net trade result to
equal zero after the fees entered.
Break-Even Price =
(Purchase Value + Buy Fee + Sell Fee + Other Fees)
÷ Number of Shares
If your eventual sale price is higher than this amount,
the calculator will generally show an estimated profit.
If it is lower, the calculator will generally show an
estimated loss.

Stock Profit Calculator FAQs
Stock profit is calculated by subtracting the total purchase cost and trading fees from the net amount received when the shares are sold. This calculator includes both buying and selling fees in the estimate.
A basic formula is Stock Profit = Sale Proceeds - Purchase Cost - Trading Fees. If the result is negative, the trade represents an estimated loss instead of a profit.
Stock ROI measures the net profit or loss as a percentage of the total amount invested. It is calculated by dividing net profit by total purchase cost and multiplying by 100.
The break-even stock price is the approximate selling price per share needed to recover the original purchase cost and the trading fees entered into the calculator.
Yes. Brokerage commissions and other trading fees reduce net profit. Even small fees can affect returns, especially on smaller trades or when trading frequently.
No. Capital gains taxation depends on jurisdiction, holding period, account type, tax rules, and personal circumstances. This calculator focuses on trading profit or loss before tax.
