# How do I calculate shipping costs to include on my website?

**Shipping cost is more than just the courier rate.**

In reality, your total shipping cost is calculated as:

**Shipping cost = Courier rate + Weight / volumetric surcharge + Service fee**

To avoid overcharging (or losing margins), businesses should always use
 **zone-based rates** for more accurate shipping calculations.
