True unit cost
Allocate every shipment-level charge before comparing supplier quotes or setting a retail price.
Decision map
Use the number to answer a business question.
Each tool on Profit Per Order exposes its assumptions. The purpose of this hub is to connect those formulas instead of treating every metric in isolation.

Worked guidance
Read the model before you use the threshold.
These guides use explicit formulas, assumptions and worked examples. They are planning references, not market benchmarks.
Free Shipping Threshold Examples for Three Margin Profiles
Compare low-, medium- and high-margin products to see why one universal free-shipping threshold can quietly destroy contribution.
