Percentage Variance Formula
The following formula is used to calculate the percentage variance:
Variables:
- PV is the percentage variance (%)
- OV is the original value
- NV is the new value
To calculate the percentage variance, subtract the original value from the new value, divide by the original value, and then multiply by 100 to get the result as a percentage.
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. For a positive original value, positive percentage variance indicates an increase and negative variance indicates a decrease. With a negative original value, the percentage sign alone does not indicate direction; a zero original value is undefined.
How to Calculate Percentage Variance?
The following steps outline how to calculate the percentage variance:
- First, determine the original value (OV).
- Next, determine the new value (NV).
- Use the formula PV = ((NV - OV) / OV) * 100.
- Finally, calculate the percentage variance (PV).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Original Value (OV) = 150
New Value (NV) = 175
