How to Use a Percentage Calculator?

Here's a step-by-step guide on how to use a Percentage Calculator:

To Calculate the Percentage of a Value

Enter the percentage in the "Percent (%)" field and the number you want to calculate it from in the "Of Number" field. Then click "Calculate" to see the result.

For example:

What is 20% of $60?

20% is 20/100 multiplied by $60:

20% × $60 = 20/100 × $60 = 0.2 × $60 = $12

To Calculate What Percentage One Number is Of Another

Enter the first number in the "Number (X)" field and the second number in the "Of Number (Y)" field. Then click "Calculate" to find out what percentage the first number is of the second.

For Example:

$12 is what percent of $60?

$12 is divided by $60 and multiplied by 100%:

($12 / $60) × 100% = 20%

To Calculate the Percentage Change

Enter the original value in the "Original Value" field and the new value in the "New Value" field. Then click "Calculate" to find the percentage change between the two values.

For Example:

What is the percentage change from $40 to $50?

The difference between $50 and $40 is divided by $40 and multiplied by 100%:

(($50 - $40) / $40) × 100% = 0.25 × 100% = 25%
