Calculate Percentage Change Now →Understanding Percentage Change
Percentage change expresses the difference between an initial value and a final value as a percentage. It indicates whether the quantity has increased or decreased and by how much relative to the original value.
The Formula for Percentage Change
The basic formula is:
Percentage Change = [(Final Value - Initial Value) / Initial Value] * 100
A positive result indicates an increase, while a negative result indicates a decrease.
Steps to Calculate Percentage Change
- Determine the Initial and Final Values: Identify the starting and ending quantities you want to compare.
- Calculate the Difference: Subtract the initial value from the final value.
- Divide by the Initial Value: Divide the difference by the initial value. This gives you the relative change.
- Multiply by 100: Multiply the result by 100 to express the change as a percentage.
Examples of Percentage Change Calculations
Example 1: Increase in Sales
A store's sales increased from $5,000 in January to $7,500 in February. Let's calculate the percentage change:
- Initial Value: $5,000
- Final Value: $7,500
- Difference: $7,500 - $5,000 = $2,500
- Relative Change: $2,500 / $5,000 = 0.5
- Percentage Change: 0.5 * 100 = 50%
Therefore, the store experienced a 50% increase in sales.
Example 2: Decrease in Stock Price
A stock's price decreased from $120 per share to $90 per share. Let's calculate the percentage change:
- Initial Value: $120
- Final Value: $90
- Difference: $90 - $120 = -$30
- Relative Change: -$30 / $120 = -0.25
- Percentage Change: -0.25 * 100 = -25%
Therefore, the stock experienced a 25% decrease in price.
