Percentage Change Calculator

The formula for calculating percentage change is:

1. Subtract the final value from the initial value.
2. Divide the result by the initial value
3. Multiply by 100 to convert to a percentage
4. Round the result to two decimal places
1. If the result is positive, it's a percentage increase.
2. If the result is negative, it's a percentage decrease.

If the old value is 80 and the new value is 100:

• Initial Value: 80
• Final Value: 100
• Percentage Change: [(100 - 80) / 80] x 100 = (20 / 80) x 100 = 25%

The percentage change is an increase of 25%.
