Calculate Percentage Change Now! →The Basic Concepts
Percentage change represents the extent to which a value gains or loses magnitude. It's expressed as a percentage of the original value. A positive percentage indicates an increase, while a negative percentage indicates a decrease.
Calculating Percentage Increase
To calculate a percentage increase, follow these steps:
- Find the Difference: Subtract the original number from the new number.
- Divide by the Original Number: Divide the difference by the original number.
- Multiply by 100: Multiply the result by 100 to express it as a percentage.
Here's the formula:
Percentage Increase = ( (New Value - Original Value) / Original Value ) * 100
For example, if a product's price increased from $80 to $100, the percentage increase is:
( (100 - 80) / 80 ) * 100 = 25%
Calculating Percentage Decrease
To calculate a percentage decrease, use a similar approach:
- Find the Difference: Subtract the new number from the original number.
- Divide by the Original Number: Divide the difference by the original number.
- Multiply by 100: Multiply the result by 100 to express it as a percentage.
Here's the formula:
Percentage Decrease = ( (Original Value - New Value) / Original Value ) * 100
For example, if a stock price decreased from $50 to $40, the percentage decrease is:
( (50 - 40) / 50 ) * 100 = 20%
