Factors affecting shipping costs
Understanding apparently guides on how to calculate shipping costs and factors affecting shipping costs will help business owners control business activity efficiently. Let’s explore factors that influence shipping costs as follows:
Package dimensions and weight
Package dimensions and weight are two significant factors in determining shipping costs.
- Weight: The carriers based on the shipment weight calculate the handling fee, which is one of the components of shipping cost.
- Size: The package with a large size will be charged more shipping costs although its weight is light.
- Dimensional weight: The carrier root size of the package consists of length, width, and height to estimate volumetric weight and shipping costs. The formula is:
DIM weight (volumetric weight – centimeters) = (Length x Width x Height) / Dimensional factor (5000 or 6000).

Shipping distance
The bigger the distance, the higher the shipping costs because of the increase in fuel surcharges, delivery time, and special zones. Business owners should know exactly the distance for shipping consisting of pickup and the delivery address to manage shipping costs effectively.
Carriers will divide geographical areas into many shipping zones with different shipping costs. The cost of remote areas with fewer delivery services is higher than in normal zones. Overall, shipping zones are a basic rule for carriers to determine shipping costs for a shipment.
Delivery speed
The chosen delivery speed between these options, like economy, standard, and expedited, also impacts shipping costs. Here is a breakdown of their influence on costs:
- Economy: This is the slowest and lowest shipping method, applied for ground transportation (such as truck or rail) or any shipment that needs to be shipped non-urgent.
- Standard shipping: If you have a shipment, you want to look for a delivery service that is faster than economy and cheaper than expedited, let you choose standard shipping.
- Expedited shipping: For air methods, sellers and buyers often choose this method to ship their cargo with high safety.
Shipping carrier
The different carriers will have different pricing structures and service options. The shipper is based on shipping demand, the features of the package, and price to decide the suitable carriers.
- USPS is divided into two types of service options. The shape and weight of the package will decide the shipping costs for the First-Class Mail option. For Priority Mail, shipping costs will be calculated based on size, weight, and distance from start to end point.
- UPS: The pricing structures have three levels. Daily Rates apply to individual accounts that sign contracts with UPS. Retail Rates will apply if you ship packages from UPS locations. Air Freight Rates apply for large shipments that need supporting services such as pickup, delivery, and customs clearance.
- FedEx breaks down into International Priority Rates(IP service) and International Economy Rates (IE service). IP service has a high cost and short delivery time while IE service has a low cost and long transit time. Therefore, based on the demand for shipping cargo, you will choose the suitable option.

Packaging
The type and amount of packaging can affect freight charges because these elements consist of dimensional weight, the weight of packaging materials, and the actual weight of the package. If shippers want to optimize shipping costs, they should use packaging materials that fit in objects to decrease the packaging fees and the overall costs.
To manage shipping costs effectively and avoid extra fees, shippers should consider packing the products carefully and efficiently.
Insurance and additional services
The optional services like insurance, signature confirmation, and Saturday delivery are not included in the shipping cost. If shippers want to guarantee their shipment during transit time, they need to buy cargo insurance. In case of damage or natural disaster, the insurance company will compensate for them.
