ShipStation does calculate shipping cost with its rate calculator feature.
You can use the calculator to see the cost of the shipping service you’re currently using for a shipment and compare it to other available services.
But ShipStation does not use the calculated cost to auto-select the cheapest rate for every shipment.
But, you can integrate a platform called String into your ShipStation account to automatically calculate the full shipping cost of every order and auto-select the cheapest shipping rate.
You can learn more about how String works here.
You can also get a free savings analysis from String by requesting a demo at www.meetstring.com.
