# percentage increase/decrease calculator:

To calculate the percentage increase or decrease, you need to find the difference between the two values, divide it by the original value, and multiply by 100%. The formula is:

Percentage change = ((new value – old value) / old value) x 100%

Here’s an example:

Suppose you earned \$2,500 last month and \$3,000 this month. What is the percentage increase in your earnings?

Step 1: Find the difference between the two values: \$3,000 – \$2,500 = \$500.

Step 2: Divide the difference by the original value: \$500 / \$2,500 = 0.2.

Step 3: Multiply the quotient by 100% to express it as a percentage: 0.2 x 100% = 20%.

So the percentage increase in your earnings is 20%.

Here’s the calculator:

Input the old value: (e.g. 2500) Input the new value: (e.g. 3000)

Result: (percentage increase or decrease)

## step-by-step guide on how to calculate percentage increase or decrease:

To calculate the percentage increase or decrease, you need to find the difference between the two values, divide it by the original value, and multiply by 100%. The formula is:

Percentage change = ((new value – old value) / old value) x 100%

Here’s an example:

Suppose the price of a stock increased from \$50 to \$60. What is the percentage increase?

Step 1: Find the difference between the two values: \$60 – \$50 = \$10.

Step 2: Divide the difference by the original value: \$10 / \$50 = 0.2.

Step 3: Multiply the quotient by 100% to express it as a percentage: 0.2 x 100% = 20%.

So the percentage increase is 20%.

Here’s another example:

Suppose the temperature dropped from 80 degrees Fahrenheit to 70 degrees Fahrenheit. What is the percentage decrease?

Step 1: Find the difference between the two values: 70 – 80 = -10.

Step 2: Divide the difference by the original value: -10 / 80 = -0.125.

Step 3: Multiply the quotient by 100% to express it as a percentage: -0.125 x 100% = -12.5%.

So the percentage decrease is 12.5%.
