1. What is Percentage Increase?

Percentage increase measures how much a stock's price has grown relative to its original price. It's a key metric for evaluating investment performance and comparing different stocks' growth rates.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Price — Current stock price
• Old Price — Original purchase price

Explanation: The formula calculates the difference between the new and old price, divides by the original price to get the relative change, then converts to a percentage.

3. Importance of Calculating Stock Gains

Details: Percentage increase helps investors evaluate performance, compare different investments, and make informed decisions about holding or selling stocks.

4. Using the Calculator

Tips: Enter both prices in dollars (without currency symbols). The calculator automatically handles decimal values (e.g., $125.50 can be entered as 125.5).

5. Frequently Asked Questions (FAQ)

Q1: Should I include dividends in the calculation?
A: This calculator shows price appreciation only. For total return, you would need to include dividends and other distributions.

Q2: What's considered a good percentage increase?
A: This depends on time frame and market conditions. Historically, 7-10% annual return is considered good for stocks.

Q3: How does this differ from percentage points?
A: Percentage increase is relative to the original value. Percentage points measure absolute difference between two percentages.

Q4: Can I use this for multiple stock purchases?
A: For multiple purchases at different prices, you would need to calculate weighted average cost basis first.

Q5: What if my stock price decreased?
A: The calculator will show a negative percentage, indicating a loss rather than a gain.
