Calculate the exact percentage growth, absolute increase, and expansion factor between an initial baseline value and a new final value.
Moving from 100 to 125 is an increase of 25% (+25).

A Percentage Increase Calculator measures the relative upward growth from an initial baseline number to a higher final value.
Mathematical Formula: Percentage Increase (%) = [(New Value − Original Value) / Original Value] × 100. Absolute Increase = New Value − Original Value.
Baseline Significance: The percentage increase is always calculated relative to the original starting value. An increase from 50 to 100 is a 100% increase, whereas an increase from 100 to 150 is a 50% increase.
Practical Uses: Commonly applied in measuring annual salary raises, business revenue growth, stock price appreciation, inflation, and population growth.
What is the formula for calculating percentage increase?
Subtract the original value from the new value, divide that difference by the original value, and multiply by 100.
