Cubic Discount

Cubic discount transforms the shipping sector by introducing a fresh pricing strategy emphasizing volume rather than weight. This groundbreaking model holds the capacity to transform logistics, enhancing effectiveness and diminishing expenses. As businesses optimize their supply chains, acknowledging the significance of cubic discount in shipping becomes imperative.

This blog explores how cubic discount is reshaping the industry, providing insight into its workings, advantages, and effects on expenses and operational effectiveness.

 Understanding Cubic Discount

Cubic discount is a pricing strategy that applies discounts according to the cargo volume, measured in cubic units, instead of its weight. Cubic shipping provides a cost-effective alternative that lets you save money by not relying on weight for pricing. Instead, the postage costs are calculated based on the cubic dimensions and zone of the shipment. The transition from pricing based on weight to pricing based on volume is significant in sectors where the size of items does not align with their weight. Offering discounts according to the space filled encourages better packing and shipping practices, enabling shippers to make the most of available space and reduce expenses. This approach helps carriers maximize their load capacities and gives shippers lower rates for utilizing space effectively.

How Does USPS Cubic Pricing Work?

Shipments bound for addresses within the United States may be eligible for exclusive pricing through our affiliated carrier USPS, thanks to their size-based criteria. This unique cubic pricing feature offers an extra discount, typically applicable to bulkier packages with smaller volumes. Opting for cubic shipping presents a financially advantageous alternative. It allows you to save on costs without being dependent on weight. Instead, the postage expenses are calculated based on the shipment’s cubic dimensions and designated zone.

1. Volume Measurement: Cubic pricing calculates the shipping cost based on the packages’ cubic volume. This involves measuring a shipment’s height, width, and length to determine its total cubic space. For instance, if a package measures 2 feet in height, 3 feet in width, and 4 feet in length, its cubic volume would be 24 cubic feet.

2. Volume-Based Pricing Tiers: Shipping costs are determined by the total cubic volume occupied by the shipment. Carriers often set pricing tiers based on specific cubic measurements. 

3. Calculation Formula: The general formula for cubic pricing is

Length x Width x Height / 1728 = Cubic Feet

where the carrier predetermines the price per cubic unit, this straightforward calculation helps shippers understand their costs upfront and manage expenses more effectively by optimizing how goods are packed and consolidated.

4. Incentivizing Efficient Packing: Shippers are incentivized to pack their goods more compactly and efficiently since costs are based on volume. This leads to better utilization of space in shipping containers and vehicles, which can reduce the number of trips required, thus lowering overall shipping costs and environmental impact.

5. Application Across Various Shipping Modes: Cubic pricing can be applied to various shipping modes, including ground, air, and sea transport. Each mode may have different pricing structures based on the typical cost and space availability, but the underlying principle of volume-based pricing remains consistent.

6. Benefits Over Weight-Based Pricing: Unlike weight-based pricing, cubic pricing is less likely to penalize shippers of lightweight, bulky items. This creates a fairer pricing model that more accurately reflects the cost of transporting goods based on the space they occupy rather than their weight, which may not be proportional to the space used.

7. Adjustments for High-Density Goods: For items that are particularly dense and heavy relative to their size, adjustments or exceptions might be made to ensure pricing fairness. This flexibility allows cubic pricing to accommodate a wide range of goods without disadvantaging certain shipments.

Exploring the Benefits of Cubic Discount 

  • Optimized Space Utilization

Cubic discount encourages shippers to pack more efficiently by focusing on the volume rather than the weight of shipments. This maximizes available space within containers and transport vehicles, reducing the number of shipments needed and overall logistical costs.

  • Cost Reduction

Cubic discount aligns pricing more closely with the actual costs incurred by shipping services, such as the use of cargo space. This can significantly reduce costs for shippers, particularly for bulky but lightweight items, as these items traditionally incur higher shipping costs due to their size rather than weight.

  • Incentivizes Efficient Packing

The pricing model incentivizes businesses to reevaluate and improve their packing strategies to maximize space, which can lead to innovations in packaging and consolidation. This can reduce the material costs and environmental impact associated with excess packaging.

  • Enhanced Carrier Efficiency

From a carrier perspective, cubic discount promotes the full utilization of transport capacity, leading to fewer trips and optimized routes. This efficiency reduces fuel consumption and emissions and improves the turnaround time across supply chains.

  • Scalable and Flexible Pricing

Cubic discount provides a scalable and flexible pricing model that can adapt to various cargo and shipping needs. It offers transparent pricing that can be easily adjusted based on different volume thresholds, providing clear cost benefits to customers for bulk shipping.

  • Environmental Benefits

Cubic discount helps lower shipping operations’ carbon footprint by reducing the number of shipments and optimizing container usage. This is increasingly important as companies worldwide strive to meet stricter environmental regulations and fulfill corporate sustainability goals.

  • Improved Customer Satisfaction

Customers can benefit from potentially lower shipping costs and more predictable pricing based on volume. This transparency and cost-effectiveness can enhance customer satisfaction and loyalty.

  • Market Competitiveness

Companies that adopt cubic discounts can gain a competitive edge by offering more cost-effective and efficient shipping options. This can be a key differentiator in industries where shipping costs significantly impact the overall cost of goods sold.

  • Encourages Bulk Purchases: 

For retailers and manufacturers, the cubic discount model can encourage larger, less frequent orders, which can help stabilize production and inventory management and reduce operational complexities and costs.

  • Adaptability to Industry Trends:

As the e-commerce industry expands, there is an increasing need for faster and more efficient shipping solutions. Cubic discount offers a framework that enables businesses to scale and adapt to the ever-changing dynamics of the market.


In conclusion, introducing a cubic discount significantly transforms the shipping sector. This groundbreaking pricing strategy adjusts expenses according to the size of shipments rather than their weight, promoting better space utilization and resulting in considerable savings. By motivating shippers to optimize their packaging, cubic discounts improve logistical processes. They also contribute to environmental sustainability by reducing the frequency of trips and minimizing the carbon emissions associated with shipping.
