Investor Profit Calculation: Buying and Selling Stocks – What’s Behind the Numbers?

When investing in stocks, one of the most common scenarios is buying shares at a specific price, watching the value increase, and selling for a profit. Let’s explore a clear, real-world example to understand how investor profits are calculated — specifically, what happens when an investor buys 100 shares at $50 each, the stock rises by 20%, and then all shares are sold.

The Scenario

An investor purchases 100 shares of a stock at $50 per share.
Within a short period, the stock price increases by 20%. The investor then sells all 100 shares.

Step-by-Step Breakdown

Initial Investment:

• Number of shares: 100
  
• Purchase price per share: $50
  
• Total cost = 100 × $50 = $5,000

---

Stock Price Increase:

• The price rises by 20%
  
• New price per share = $50 + (20% of $50) = $50 + $10 = $60

---

Sale Revenue:

• Selling price per share: $60
  
• Total sale amount = 100 × $60 = $6,000

---

Calculating Profit:
Profit = Sale Revenue – Initial Investment
Profit = $6,000 – $5,000 = $1,000

---

Summary

By buying 100 shares at $50 and selling them after a 20% price increase to $60, the investor generates a total profit of $1,000. This simple example illustrates how percentage gains directly translate into financial returns in stock investing.
