How is the Threshold calculated?

The threshold figure you see on the Order Summary and Sales Summary is calculated by taking the average of all FBA fees for an item + the standard deviation of those fees. If there the standard deviation on the Sales Summary sheet is $0.00 for an item, that means the fees were always the same in the sales data (they didn’t deviate). You can see a summary of the averages and standard deviations for each item on theĀ Sales Summary sheet.
