I believe you are interested in calculating the variance from a set of data related to salaries. Variance = square of the standard deviation, where: s= square root[sum (xi- mean)2/(n-1)] where mean of the set is the sum of all data divided by the number in the sample. X of i is a single data point (single salary). If instead of a sample of data, you have the entire population of size N, substitute N for n-1 in the above equation. You may find more information on the interpretation of variance, by searching wikipedia under variance and standard deviation. I note that an advantage of using the standard deviation rather than variance, is because the standard deviation will be in the same units as the mean.

The standard deviation is the square root of the variance. So, if variance = 03 = 3 the std dev = sqrt(3) = 1.732
How can I calculate portfolio variance in Excel?
To calculate portfolio variance in Excel, you can use the formula SUMPRODUCT(COVARIANCE.S(array1,array2),array1,array2), where array1 and array2 are the returns of the individual assets in your portfolio. This formula takes into account the covariance between the assets and their individual variances to calculate the overall portfolio variance.
