SALES MIX VARIANCE= standard sales-revised std sales

Revised standard sales can be calculated by dividing the amount of sales over a given length of time. This is a more accurate way to calcuating sales rather than a projection.

One can find out the standard sales tax on several different websites. Some of these include: the IRS website, Sales Tax Institute, and individual websites for each state.

Total number of sales divided by total number of hours.
