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

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.

## What is the percentage change or percent increase?

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.

Wikipedia states that,

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 while.

## Percentage Increase Formula

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 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.

## How to calculate the percent increase?

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 a 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.

### Example - % increase

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

`Percent Increase = 25%`

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

### Example - % decrease

A toy manufacturer company was producing 800 pieces of electronic toys per day. Due to 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

`Percent decrease = 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 the percent increase formula, the value decreases in percentage.

## FAQs

### How do you calculate percentage increase?

To calculate the percentage increase:

• Subtract the old value from the new value.

`i.e., 40 – 30 = 10`

• Divide the resulting value by the old value.

`10 / 30 = 1 / 3`

• Multiply the answer from the previous step with 100

`(1 / 3) × 100 = 33.3%`

• The value you get after multiplication is the percentage increase

### How do I calculate percentage increase on a calculator?

To calculate percentage increase on a calculator:

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

### How do I calculate a percentage between two numbers?

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%.`

### What is the percentage difference between the two numbers?

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 a percentage difference between two numbers. (1 / 3) × 100 = 33%

### What is the formula to calculate the percentage?

The formula to calculate the percentage is:

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