1. What is Percentage Increase?

Percentage increase measures how much a value has grown relative to its original amount, expressed as a percentage. In stock analysis, it shows how much a stock's price has risen compared to its previous price.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Price — Current stock price ($)
• Old Price — Previous stock price ($)

Explanation: The formula calculates the difference between new and old price, divides by the old price to get relative change, then converts to percentage by multiplying by 100.

3. Importance of Percentage Increase Calculation

Details: Calculating percentage increase helps investors evaluate stock performance, compare different investments, and make informed trading decisions.

4. Using the Calculator

Tips: Enter both old and new prices in dollars. The old price must be greater than zero. Results show the percentage increase (positive) or decrease (negative).
