Percentage Variance Calculator





Formula

The following formula is used to calculate the percentage variance:

\[ PV = \left( \frac{NV - OV}{OV} \right) \times 100 \]

What is Percentage Variance?

Percentage variance is a measure of how much a number has changed in comparison to its original value, expressed as a percentage. It is commonly used in finance, statistics, and general data analysis to understand the relative change between two numbers. A positive percentage variance indicates an increase, while a negative percentage variance indicates a decrease.

Example Calculation

Let's assume the original value (OV) is 100, and the new value (NV) is 120:

Step 1: Subtract the original value from the new value:

\[ NV - OV = 120 - 100 = 20 \]

Step 2: Divide the result by the original value:

\[ \frac{20}{100} = 0.2 \]

Step 3: Multiply the result by 100 to get the percentage:

\[ 0.2 \times 100 = 20\% \]

So, the percentage variance is 20%.
