# Percent Calculator (Change)

### Percentage Change Calculator

Using this tool you can find the percent increase for any value. So, we think you reached us looking for answers to questions like:

1) What is the percentage increase from 180 to 280? 2) What is the absolute increase from 180 to 280. Or may be: What is the percent change from 180 to 280?

See the solution to these problems just after below.

## How to calculate percent change - Step by Step

Percent increase or decrease measures percent changes between two values. Use this calculator when comparing an old value to a new value.

The Percent Calculator (Change) uses this formula:

Where |old value| represents the absolute value of the reference (this is made in order to work well with both positive and negative values of old value and New Value. Note that percent change and relative change mean the same thing. It can be a percent increase or a percent decrease depending on the new and the old values. If the new value is greater than the old value, the result will be positive and we will have a increase. On the other hand, if the new value is smaller than old value, the result will be negative and we will have a we have a decrease. The old value, as a reference, may be: a theoretical, the actual, the correct, an accepted, an optimal, the starting, and so on. See more about percent percent change here.

Here are the solutions to the questions stated above:

### 1) What is the percentage increase from 180 to 280?

Use the above formula to find the percent change. So, replacing the given values, we have

Percent change = 280 - 180180 × 100 = 55.555555555556 % (increase)

Where: 180 is the old value and 280 is the new value. In this case we have a % of increase because the new value is greater than the old value.

### 2) What is the absolute increase from 180 to 280?

This problem is not about percent or relative change, but about absolute change. Its solution is very simple:

Absolute change, or

= 280 - 180 = 100 (increase)

## What is the difference between"percentage difference" and "percentage change"?

It is important to note that the terms "percentage difference" and "percentage change" are related with each other. However, they have different meanings in different circumstances, and they are calculated differently.

### Percentage Change

This term refers to a value where one can calculate how much something has changed over time. It is often used when describing financial metrics such as prices, revenues, or profits for a given period of time. The formula for percentage change is:

#### Example:

If you are comparing the heights of one person over the years from 160 cm tall to 180 cm tall:

Percent change = 185 - 170 |170| × 100% =

So, the "Percentage Change" is: 8.824%

### Percentage Difference

On the other hand, this measures the relative difference between two values or how much one value differs from another. It is usually used to compare two quantities without taking into account time variation. The formula for the percentage difference is:

% difference = |x - y(x + y)/2| × 100%

### Example:

If you are comparing the heights of two people, one 160 cm tall and the other 180 cm tall:

% difference = |170 - 185(170 + 185)/2| × 100% =

Thus, the "Percentage Difference" is: 8.451%
