The percentage decrease calculator is specially designed to calculate percent decrease in the value from the actual value by means of hundred parts. But before we move further to evaluate the value of the percent decrease, let us make sure that you must go through the following context.

In mathematical analysis:

**“A considerable decrease in the original value that depends upon 100 parts of the original value is known as the percentage decrease.”**

It is the opposite process of percentage increase.

**For example:**

If the price of a costume is decreased from $20 to $10 because of Black Friday Sale, we say that the actual decrease in the price is 50% in terms of the percentage.

Well, it is not a huge task to find a percent decrease at all. All you need to know is to memorize the following equation:

$$ \text{Percent Decrease} = [\frac{\text{Actual Value} - \text{New Value}}{\text{Actual Value}} * 100] $$

In everyday life, it is very important that you take into account the use of the profit and loss percentage calculation. To make you an expert in doing so, we are going to solve a couple of examples to elaborate the concept in more depth. Stay in touch!

**Example # 01:**

A reader reads a number **220** as **120**.

**Solution:**

As we know that the percentage decrease formula is as follows:

$$ \text{Percent Decrease} = [\frac{\text{Actual Value} - \text{New Value}}{\text{Actual Value}} * 100] $$

Putting the initial and final values:

$$ \text{Percent Decrease} = [\frac{220 - 120}{220} * 100] $$

$$ \text{Percent Decrease} = [\frac{100}{220} * 100] $$

$$ \text{Percent Decrease} = 0.454 * 100 $$

$$ \text{Percent Decrease} = 45.4% $$

How simple is that! But wait. To make it more accurate and fast, use a percent decrease calculator.

**Example # 02:**

If the price of the **1 Tola** Gold suddenly falls from **$664** to** $660**?

**Solution:**

Using the percent decrease formula:

$$ \text{Percent Decrease} = [\frac{\text{Actual Value} - \text{New Value}}{\text{Actual Value}} * 100] $$

$$ \text{Percent Decrease} = [\frac{664 - 660}{664} * 100] $$

$$ \text{Percent Decrease} = [\frac{4}{664} * 100] $$

$$ \text{Percent Decrease} =0.00602 * 100 $$

$$ \text{Percent Decrease} = 0.602% $$

While doing manual calculations, you may not be able to solve for maximum decimal places. This is why it is a preferable practice to use the percent loss calculator for getting the most extreme possible decimal value in the outputs.

**Example # 03:**

A chemist performs an experiment by maintaining the temperature upto **200K**. Suddenly it gets reduced to a remarkable value which is **169K**. How to find percentage decrease?

**Solution:**

We know that the percent decrease formula is given as:

$$ \text{Percent Decrease} = [\frac{31}{200} * 100] $$

$$ \text{Percent Decrease} = 0.155 * 100 $$

$$ \text{Percent Decrease} = 15.5% $$

In case you lack time, you can use a free percentage drop calculator for instant results.

**Example # 04:**

If the sugar level of Harry gets decreased from **150** to **105?**

**Solution:**

We know that:

$$ \text{Percent Decrease} = [\frac{150 - 105}{150} * 100] $$

$$ \text{Percent Decrease} = 30% $$

Which is our required answer.

The Percentage reduction calculator with the following steps to find percent loss related calculations in seconds:

**Input:** You need to follow only the simple steps as below:

- Enter the initial value
- Also, enter the final value in the same way
- Hit the calculate button

**Output:** The percent reduction calculator calculates:

- Exact difference among the start and end value
- Percent of decrease

The actual decrease of percentage among these both values is 27.1%. For calculations, scroll above or use percent decrease calculator.

Here we have:

$$ Percentage = \frac{9}{10} * 100 $$

$$ Percentage = 0.9 * 100 $$

$$ Percentage = 90% $$
