A Stock Profit Calculator is a financial tool that helps investors determine how much money they have made or lost on a stock investment.
It calculates key metrics such as:
- Total profit or loss
- Return on investment (ROI)
- Percentage gain or loss
- Profit after fees and commissions
- Total investment value
What Does a Stock Profit Calculator Do?
A stock profit calculator compares:
- Purchase Price (what you paid for the stock)
- Selling Price (what you sold it for or its current market value)
- Number of Shares
- Fees or Commissions (optional)
The calculator then determines your overall profit or loss.
Basic Formula
Profit or Loss
Profit = (Selling Price − Purchase Price) × Number of Shares
Return Percentage
ROI (%) = (Profit ÷ Initial Investment) × 100
Example
Suppose you:
- Bought 100 shares at $50
- Sold 100 shares at $65
Initial Investment
100 × $50 = $5,000
Sale Value
100 × $65 = $6,500
Profit
$6,500 − $5,000 = $1,500
Return
($1,500 ÷ $5,000) × 100 = 30%
The calculator would show:
- Profit: $1,500
- Return: 30%
What Information Is Needed?
Most stock profit calculators require:
| Input | Description |
|---|---|
| Purchase Price | Price paid per share |
| Selling Price | Current or selling price per share |
| Number of Shares | Shares owned |
| Fees/Commissions | Optional trading costs |
| Dividends | Optional income received |
Including Dividends
Some advanced calculators include dividends.
Example
- Capital Gain: $1,500
- Dividends Received: $200
Total Profit:
$1,500 + $200 = $1,700
This provides a more accurate measure of total investment return.

50 × $80 = $4,000
Loss:
$4,000 − $5,000 = −$1,000
