Logistics Calculators
Freight, shipping volume, pallet, dimensional weight & delivery cost calculators.
What Are Logistics Calculators?
Logistics calculators help supply chain managers, freight coordinators, warehouse operators, and e-commerce businesses quantify the costs, capacities, and efficiencies of moving, storing, and managing goods. Accurate logistics calculations reduce freight overpayment, prevent stockouts, optimise warehouse space, and improve delivery cost predictability.
Freight and shipping cost calculators estimate the cost of moving goods based on weight, volume, destination, and service level. Carriers charge based on either actual weight or dimensional weight (volumetric weight) β whichever is greater. Dimensional weight penalises light, bulky shipments: it is calculated as Length Γ Width Γ Height Γ· Dimensional Factor (typically 5,000 for air freight in cm/kg, or 139 for ground in inches/lb). Understanding whether your shipments are weight-rated or dimension-rated is the first step in freight cost management.
Pallet and container loading calculators determine how many units, boxes, or pallets fit into a given space β truck, container, or warehouse bay. Efficient loading maximises the use of paid cubic capacity. A standard EUR pallet is 1,200 Γ 800mm; a UK industrial pallet is 1,200 Γ 1,000mm. A standard 20-foot shipping container has approximately 33 mΒ³ of usable volume and a max payload of about 28 tonnes.
Inventory management calculators compute the optimal order quantity, reorder point, and safety stock level to balance carrying costs against the risk of stockouts. The Economic Order Quantity (EOQ) formula minimises total inventory cost by finding the order size that balances the fixed cost of placing an order against the variable cost of holding stock. Safety stock provides a buffer against demand variability and lead time uncertainty.
Logistics cost calculators aggregate freight, warehousing, labour, and inventory carrying costs to give a total logistics cost as a percentage of revenue β a key supply chain efficiency benchmark. Typical logistics costs run at 8β12% of revenue for manufacturing businesses; e-commerce fulfilment typically runs 10β20% depending on average order value and shipment size.

Freight & Shipping
Dimensional (volumetric) weight: Air freight: L Γ W Γ H (cm) Γ· 5,000 = kg; Ground (UPS/FedEx): L Γ W Γ H (inches) Γ· 139 = lb. Charge weight = max(Actual Weight, Dimensional Weight). A parcel measuring 60 Γ 40 Γ 30 cm weighing 4 kg has a volumetric weight of 60Γ40Γ30Γ·5,000 = 14.4 kg β so it is billed at 14.4 kg despite its low actual weight. Our freight calculator handles both weight types and multiple carriers.
Freight class (for US LTL shipments) is determined by the NMFC classification system, which considers density, handling, stowability, and liability. Higher freight class = higher rate. Density (lb/ftΒ³) is the primary driver: density 50+ = Class 50 (cheapest); density < 1 = Class 500 (most expensive). Use our freight class calculator to determine the class from dimensions and weight before requesting LTL quotes.
Inventory & Safety Stock
Economic Order Quantity: EOQ = β(2 Γ Annual Demand Γ Order Cost Γ· Holding Cost per Unit per Year). For 10,000 units/year demand, Β£50 order cost, and Β£2 holding cost/unit/year: EOQ = β(2 Γ 10,000 Γ 50 Γ· 2) = β500,000 β 707 units per order. Reorder Point = (Average Daily Demand Γ Lead Time in Days) + Safety Stock.
Safety Stock = Z Γ Ο_demand Γ βLead Time. Z = service level factor (1.28 for 90%, 1.645 for 95%, 2.05 for 98%); Ο_demand = standard deviation of daily demand. A higher service level requires more safety stock but reduces stockout frequency. Inventory turnover = Annual COGS Γ· Average Inventory Value β higher turnover means capital is less tied up in stock.
Container Loading & Warehousing
Container capacities: 20ft standard: 33.2 mΒ³, 28t max payload; 40ft standard: 67.7 mΒ³, 26.7t max; 40ft high cube: 76.4 mΒ³, 26.5t max. Pallet loading: pallets per container = Floor Area Γ· Pallet Footprint (accounting for door clearance). Layer stacking height depends on product weight limits. Always verify weight does not exceed the container payload β volume and weight limits are independent constraints.
Warehouse storage density is calculated as Pallets Stored Γ· Warehouse Area (mΒ²). Typical selective pallet racking achieves 1.0β1.5 pallet positions per mΒ² of floor area; narrow-aisle racking achieves 1.8β2.2; automated storage and retrieval systems (AS/RS) can reach 3.5β5.0. Improving storage density reduces cost per pallet position β a key lever when warehouse space is expensive.

Frequently Asked Questions About Logistics Calculators
Dimensional (volumetric) weight accounts for the space a shipment occupies rather than just its mass. Air freight: L Γ W Γ H (cm) Γ· 5,000 = kg. Ground carriers (US): L Γ W Γ H (inches) Γ· 139 = lb. Carriers charge based on whichever is greater β actual weight or dimensional weight. Light, bulky shipments are usually billed at dimensional weight.
EOQ = β(2 Γ Annual Demand Γ Order Cost Γ· Holding Cost per Unit per Year). It is the order quantity that minimises total inventory cost by balancing the fixed cost of placing an order (which decreases per unit as order size rises) against the variable cost of holding stock (which increases with order size). The EOQ assumes constant demand and fixed costs.
Safety Stock = Z Γ Ο (daily demand) Γ β(Lead Time in days). Z is the service level factor: 1.28 for 90%, 1.65 for 95%, 2.05 for 98%. Higher service levels protect against stockouts but increase carrying costs. Safety stock should be recalculated whenever lead time variability or demand variability changes significantly.
A 20ft container fits approximately 10β11 standard EUR pallets (1,200Γ800mm) in a single layer, or 20β22 if double-stacked (subject to weight and height limits). A 40ft container fits 20β24 EUR pallets per layer. Actual pallet count depends on pallet footprint, container interior dimensions, loading method, and product weight limits.
Inventory Turnover = Annual COGS Γ· Average Inventory Value. It measures how many times inventory is sold and replaced in a year. Higher turnover means less capital tied up in stock and lower holding costs. Low turnover may indicate overstocking, slow-moving products, or demand forecasting errors. Industry benchmarks vary widely β groceries turn over 20β30 times/year; industrial equipment may turn 2β4 times/year.
Reorder Point (ROP) = (Average Daily Demand Γ Lead Time in Days) + Safety Stock. When stock falls to the ROP, a replenishment order should be placed so that stock arrives before the safety stock is consumed. An ROP that does not include safety stock assumes perfect lead time reliability β which is rarely the case in practice.
