## Percentage increase formula

The percent increase formula can be expressed as:

Percent increase = [(new value - original value) / original value] * 100

By using the formula above, you can calculate the percentage increase by substituting the required values in the percentage increase equation. You can also calculate the decrease in percentage by using the below formula:

Percent decrease = [(original value - new value)/original value] * 100

If you are using the percent increase formula and your answer is in negative, it means that there is a decrease in percentage instead of an increase.

## How to calculate percentage increase?

If you are wondering how to find percentage increase, you are at the right place. We will explain step by step method to calculate the increase in percentage by using the above formula. Follow the below steps to find the percentage increase:

- Identify and write down the original and new values.
- Write down the formula and substitute the original and new value in the percentage increase formula to calculate percentage increase.

Example 1:

Let’s calculate the increase in percentage by using a real example.

Sam has been an employee of an IT company for 3 years. He stared as a junior developer earning $500 per month. He got promoted to a senior developer, and now the company has offered him a monthly salary of $1200 per month. Calculate the total percentage increase in salary.

Solution:

`Step 1:`

Identify and write down the original and new values.

Original value = $500

New value = $1200

`Step 2:`

** **Write down the formula and substitute the original and new value in the percentage increase formula.

Percent increase = [(new value - original value) / original value] * 100

Percent increase = [(1200 - 500) / 500] * 100

Percentage increase = (700/500) * 100

Percentage increase = 140 %

So, Sam’s salary has been increased by 140 percent after the promotion.

Example 2:

Sheila has been working 9 hours a day in a grocery store. Her boss has increased his duty hours, and now she has to work 7 hours per day. Calculate the percentage decrease in the working hours.

Solution:

`Step 1: `

Identify and write down the original and new values.

Original value = 9 hours

New value = 7 hours

`Step 2: `

Write down the formula and substitute the original and new value in the percentage increase formula.

Percent increase = [(new value - original value) / original value] * 100

Percent increase = [(7 - 9) / 5] * 100

Percentage increase = (-2/5) * 100

Percentage increase = -40%

So, Sheila’s working hours have been decreased by 40** % **as compared to earlier working hours. You can also use percentage decrease formula but note that the answer will be in positive if you calculate percentage decrease by using the percent decrease formula.

## How do I add 5% to a number?

To add 5% to a number, follow these steps:

- Multiply the number you want to add 5% by 5.
- Divide the answer by 100.
- After division, add the resulting number into the original number.

Example:

Let’s add 5% to 1400.

- Multiply the number you want to add 5% by 5.

1400 * 5 = 7000

- Divide the answer by 100.

7000/100 = 70

- After division, add the resulting number into the original number.

1400 + 70 = 1470

So, if 1400 is increased by 5**%,** it would become 1470.

## How do I calculate a 10% increase?

Follow these steps to calculate the increase of 10%.

- Multiply the number by 10.
- Divide the answer by 100.
- Add the result to the original number.

Example:

Let’s add 10% to 8300.

- Multiply the number by 10.

8300 * 10 = 83000

- Divide the answer by 100.

83000/100 = 830

- Add the result to the original number.

8300 + 830 = 9130

After adding 10% to 8300, the resulting number is 9130. You can add any percentage to a number by using the above method.
