# percentage change calculator:

The formula for percentage change is:

((new value – old value) / old value) x 100%

Here’s an example to show you how to use the calculator:

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

Step 1: Subtract the old value from the new value: \$60 – \$50 = \$10.

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

Step 3: Multiply the quotient by 100%: 0.2 x 100% = 20%.

So the percentage change is 20%.

Here’s the calculator:

Input the old value: 50 Input the new value: 60

Result: 20%

## step-by-step guide on how to calculate percentage change:

Step 1: Find the difference between the new value and the old value.

Step 2: Divide the difference by the old value.

Step 3: Multiply the result by 100% to express the change as a percentage.

Here’s an example to illustrate the steps:

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

Step 1: Find the difference between the new value and the old value: \$60 – \$50 = \$10.

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

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

So the percentage change is 20%.

Here’s another example:

Suppose the price of a stock decreased from \$80 to \$70. What is the percentage change?

Step 1: Find the difference between the new value and the old value: \$70 – \$80 = -\$10.

Step 2: Divide the difference by the old value: -\$10 / \$80 = -0.125.

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

So the percentage change is a decrease of 12.5%.
