A Percentage Increase Calculator is a tool used to determine the percentage change between an original value and a new, increased value. It calculates how much the value has risen, expressed as a percentage of the original value.

Formula:

The formula used is:

$$\text{Percentage Increase} = \left( \frac{\text{New Value} – \text{Original Value}}{\text{Original Value}} \right) \times 100$$

Steps:

1. Input the Original Value: This is the initial value before any increase.
2. Input the New Value: This is the updated value after the increase.
3. Calculate: The tool computes the difference between the new value and the original value, divides it by the original value, and then multiplies by 100 to get the percentage increase.

Example:

If the original value is $50 and the new value is $75, the percentage increase would be:

$$\left( \frac{75 – 50}{50} \right) \times 100 = 50\%$$

This means the value has increased by 50%.
