Formula

The formula used in the percentage decrease calculator is as follows:

$$\text{Percentage Decrease} = \left( \frac{\text{Original Value} - \text{New Value}}{\text{Original Value}} \right) \times 100\%$$

This formula clearly illustrates how much of the original value has been lost.

Examples

Example 1

The price of an item decreased from $200 to $150. The percentage decrease can be calculated as follows:

1. Original price = $200
2. New price = $150

Substitute these values into the formula:

$$\text{Percentage Decrease} = \left( \frac{200 - 150}{200} \right) \times 100\% = 25\%$$

Example 2

Suppose a salary decreased from 3500 units to 2800 units. The percentage decrease can be calculated as:

1. Original salary = 3500 units
2. New salary = 2800 units

Using the formula:

$$\text{Percentage Decrease} = \left( \frac{3500 - 2800}{3500} \right) \times 100\% ≈ 20\%$$
