# How is cost variance calculated?

## How is cost variance calculated?

Cost Variance can be calculated as using the following formulas: Cost Variance (CV) = Earned Value (EV) Actual Cost (AC) Cost Variance (CV) = BCWP ACWP.

## What is cost variance?

Cost variance (CV), also known as budget variance, is the difference between the actual cost and the budgeted cost, or what you expected to spend versus what you actually spent.

## What is mean and variance?

The mean is the average of a group of numbers, and the variance measures the average degree to which each number is different from the mean.

## What is variance used for?

Variance is a measurement of the spread between numbers in a data set. Investors use variance to see how much risk an investment carries and whether it will be profitable. Variance is also used to compare the relative performance of each asset in a portfolio to achieve the best asset allocation.

## Is Variance the standard deviation squared?

The variance (symbolized by S2) and standard deviation (the square root of the variance, symbolized by S) are the most commonly used measures of spread. We know that variance is a measure of how spread out a data set is. It is calculated as the average squared deviation of each number from the mean of a data set.
