How Percentage Increase Works
The percentage increase calculates how much a value has grown from its original amount to a new amount. The formula is:
Percentage Increase = [(Final Value – Initial Value) / Initial Value] × 100
For example, if a product’s price increases from $50 to $75, the calculation would be: [(75 – 50) / 50] × 100 = 50% increase.
