How Does a Stock Profit Calculator Work?

Profit Formula

You made money if the result was positive.
You have suffered a loss if the result was negative.
Example of Stock Profit Calculation
Suppose:
- Purchase Price: $50
- Selling Price = $70
- Shares purchased = 100
- Brokerage fee = $20
Step 1
Investment Cost
$5,000 = 50 x 100
Step 2
Selling Value
70 x 100 = $7,000
Step 3
Gross Profit
7,000 – 5,000 = $2,000
Step 4
Net Profit
2,000 – 20 = $1,980
Final Profit = $1.980
What Information Do You Need?
Most stock profit calculators ask for:
- Buy Price
- Sell Price
- Shares

- Tax (Optional).
The calculator will display the following values:
- Total Investment

How to Calculate Stock Profit Manually

Understanding Return on Investment (ROI)
ROI is a measure of how much an investment has grown.
ROI Formula
ROI (%) = Profit / Investment Cost x 100
Example:
Investment = $5,000
Profit = $1,980
ROI = (1.980/5,000) x100
ROI = 39.6%
Your investment will earn you nearly 40%.
