Example

Your store generated $125,000 in net revenue last month, with $6,250 in shipping costs.
PeriodShipping CostNet RevenueShipping Cost %
January$6,250$125,0005.0%
February$7,150$130,0005.5%
March$5,600$140,0004.0%

How It Works

Shipping Cost % divides your total shipping expenses by net revenue. Unlike Shipping %, which tracks shipping revenue collected from customers, this metric tracks your actual fulfillment cost burden. A lower percentage indicates better shipping economics or improved carrier negotiations.
