Calculate percentage Increase

Here’s a breakdown of the formula:

  • New Value: This is the current or updated value of the quantity you are measuring.
  • Old Value: This is the original or previous value of the quantity.
  • (\times 100): This step converts the absolute change into a percentage by multiplying it by 100.

The resulting percentage indicates how much the value has increased compared to its original state. A positive percentage increase indicates growth, while a negative percentage would denote a decrease or contraction.

For example, if a product’s price was $50 and it increased to $75, the percentage increase would be (\left( \frac{75 – 50}{50} \right) \times 100 = 50\%). This means the price has increased by 50%.
