Calculate Stock Percent Change Now! →The Formula for Stock Percent Change
The stock percent change is calculated using the following formula:
Percent Change = [(Current Price - Original Price) / Original Price] * 100
Where:
- Current Price: The stock's price at the end of the period.
- Original Price: The stock's price at the beginning of the period.
Step-by-Step Calculation
- Determine the Original and Current Prices: Identify the starting and ending prices for the period you're analyzing.
- Calculate the Difference: Subtract the original price from the current price.
- Divide by the Original Price: Divide the result by the original price.
- Multiply by 100: Multiply the result by 100 to express it as a percentage.
Example Scenario
Let's say you bought a share of a company for $50 (Original Price), and now it's trading at $65 (Current Price). Here's how to calculate the percent change:
Percent Change = [($65 - $50) / $50] * 100 = [($15) / $50] * 100 = 0.3 * 100 = 30%
This indicates a 30% increase in the stock's value.
Conversely, if the stock price decreased from $50 to $40:
Percent Change = [($40 - $50) / $50] * 100 = [(-$10) / $50] * 100 = -0.2 * 100 = -20%
This indicates a 20% decrease in the stock's value.
Why is Percent Change Important?
- Performance Evaluation: It offers a standardized way to evaluate stock performance, irrespective of the initial price.
- Comparison: It allows easy comparison of different stocks or investments, helping you make informed choices.
- Trend Identification: Tracking percent changes over time helps identify trends and potential investment opportunities.

Considering Fees and Other Costs
Remember to factor in any fees or commissions associated with buying or selling the stock. These costs can affect your overall return and should be included in your calculations for an accurate assessment of your investment's performance.
Realized vs. Unrealized Gains/Losses
It's also important to distinguish between realized and unrealized gains or losses. A realized gain or loss occurs when you actually sell the stock, while an unrealized gain or loss is a paper profit or loss that exists as long as you hold the stock.
