Percent increase calculator is an online tool to calculate the increase in value in terms of percentage. It also calculates the difference between two values in terms of percentage. In other words, this tool measures the change in values in percentage as compared to the original one.

The formula for percentage increase can be stated as:

**Percent Increase = [(New value – Original value) / Original value] × 100**

If the percentage increase value is negative, it means that it is a decrease in percentage.

We can also calculate the percentage decrease by using the following formula:

**Percent decrease = [(Original value - New value) / Original value] × 100**

Percent decrease is the decrease in value in terms of percentage.

It is very convenient to use a percent calculator when calculating percentage increase.** **You only have to put in the original and new value to get the total percent increase** **in value.

Here, we will explain the percentage increase definition, how percent increase calculator works, percentage formula, and how to determine percentage increase using two values.

Percentage of increase calculator** **makes the percentage change calculations very simple. You don’t have to waste your time figuring out percent increase equations. It simplifies the process; takes two values and calculates the increase in percentage.

To use this calculator, follow the steps below:

- Enter the original value in the given input box.
- Enter the new values in the given input box.
- Hit the
**Calculate**button to get the percent change. - Use the
**Reset**button to perform a new calculation.

It will instantly give you the percent increase and difference of both values. In case, you need to calculate the percentage, you can use our percentage calculator anytime.

The term **percentage increase** refers to the change in the original value when we compare it to the new value. It tells us how much value has increased over time. See a standard definition below.

**“**A percentage change is a way to express a change in a variable. It represents the relative change between the old value and the new one.**”**

It is mostly used to measure the growth in values over a period of time.

The above tool is developed to find the change in value at one click. But, we can also calculate the increase in percentage by using the formulas discussed in the previous section.

If you don’t know** **how to find percent increase, then get ready. Because we are going to illustrate the calculations with examples. To calculate the percentage increase, follow the steps given below:

- Determine the values and write them down.
- Write down the increase in percentage formula.
- Substitute the values in the formula.
- Solve the equation to get the percent increase.

See the examples below to get a clear idea to find an increase in percentage**.**

Betty was drawing a monthly salary of $1200 for the last ten months. She got a promotion and now she is earning $1500 per month. Calculate the percentage increase in Betty’s monthly salary.

__Solution__:

** Step 1:** Determine the values and write them down.

**Original value = $1200, New value = $1500**

** Step 2:** Write down the increase in the percentage formula.

**Percent Increase = [(New value – Original value) / Original value] × 100**

** Step 3:** Substitute the values in the formula.

**Percent Increase = [(1500 – 1200) / 1200] × 100**

** Step 4:** Solve the equation to get the percent increase.

**Percent Increase = (300 / 1200) × 100**

**Percent Increase = (1 / 4) × 100 = 100 / 4 = 25%**

So, Betty has got a **25% **increase in her salary after the promotion.

A toy manufacturer company was producing 800 pieces of electronic toys per day. Due to the financial issues, the owner decided to manufacture 500 pieces daily instead of 800. Calculate the percentage decrease in the manufacturing unit of toys per day.

__Solution__:

** Step 1:** Determine the values and write them down.

**Original production value = 800, New production value = 500**

** Step 2:** Write down the decrease in percentage formula.

**Percent decrease = [(Original value - New value) / Original value] × 100**

** Step 3:** Substitute the values in the formula.

**Percent decrease = [(800 - 500) / 800] × 100**

** Step 4:** Solve the equation to get the percent decrease.

**Percent decrease = (300 / 800) × 100**

**Percent decrease = (3 / 8) × 100 = 37.5%**

So, the production of toy manufacturer Company decreased by **37.5%.**

You can also use the increase in percent formula to calculate the decrease in percentage. If the answer comes out negative using percent increase formula, it means the value actually decreased in percentage.

To calculate the percentage increase:

- Subtract the old value from the new value.

i.e., 40 – 30 = 10

- Divide the resulted value by old value.

10 / 30 = 1 / 3

- Multiply the answer from the previous step with 100

(1 / 3) × 100 = 33.3%

- The value you got after multiplication is the percentage increase

To calculate percentage increase on a calculator:

- Subtract the original amount from the new amount using a calculator
- Divide the answer by original amount
- Now, multiply the answer with 100
- The final value is a percent increase

To calculate a percentage between two numbers:

- Multiply the first number with 100

i.e., 3 × 100 = 300

- Divide the answer with the second number

300 / 10 = 30

- You have the percentage between the two numbers

3 out of 10 is 30%.

The percentage difference between two numbers can be calculated by subtracting both values and dividing them by the average of both values multiplied by 100.

Suppose we have two numbers **20** and **28.** To calculate the percentage difference between the two numbers:

- Subtract both numbers from each other.
**28 – 20 = 8** - Calculate the average of both numbers.
**(20 + 28) / 2 = 24** - Divide the answer from subtraction in the first step with the average value calculated in the second step.
**8 / 24 = 1 / 3** - Multiply the answer with 100 and you have percentage difference between two numbers.
**(1 / 3) × 100 =****33%**

The formula to calculate percentage is:

**Percent Increase = [(New value – Original value) / Original value] × 100**
