Shipping & Logistics Calculators
Container Fill Rate Calculator
Calculate container fill rate by used volume or by item dimensions and quantity, to measure ocean or truck load efficiency and remaining capacity.
Delivery Time Estimator
Estimate delivery arrival time and total travel duration from distance, average travel speed, and a starting date and time for the shipment.
Dimensional Weight Calculator
Calculate dimensional weight and billable weight from package dimensions using a custom carrier dimensional factor for any service, contract, or forwarder.
Freight Cost Calculator
Calculate total freight cost from shipment weight, rate per unit weight, an optional base fee, and a fuel surcharge percentage applied to the subtotal.
Last Mile Delivery Cost Calculator
Calculate last-mile delivery cost from a base dispatch fee, distance-based rate, and per-stop charges for single or multi-drop delivery routes.
Logistics Cost Calculator
Calculate total logistics cost by combining transportation, warehousing, inventory carrying, and other expenses, with an optional cost-per-unit breakdown.
Logistics Freight Class Calculator
Determine an estimated NMFC freight class from shipment weight and dimensions using the standard density-based freight classification table used in LTL pricing.
Shipping Label Cost Calculator
Calculate total shipping label cost from label quantity, cost per label, weight surcharge per label, and any bulk discount percentage applied at higher volume.
Shipping Weight Calculator
Calculate dimensional and billable shipping weight from package dimensions using standard domestic, express, and metric carrier divisors like 139 or 5000.
Supply Chain Inventory Calculator
Calculate economic order quantity (EOQ) or inventory reorder point from annual demand, order cost, holding cost, daily demand, and supplier lead time.
The Math Carriers Use to Set Your Shipping Bill
Shipping costs are calculated using rules that aren't always obvious from the outside — dimensional weight can override actual weight, freight class depends on density and handling characteristics as much as raw weight, and last-mile delivery is disproportionately expensive relative to the rest of a shipment's journey. Ten calculators here work through the actual formulas carriers and logistics teams use to price and plan shipments.
Popular Shipping & Logistics Calculators
Ten tools span freight pricing, container loading, and delivery:
- Dimensional Weight Calculator — calculates dimensional weight from package size to determine actual billable weight.
- Freight Cost Calculator — estimates shipping cost based on weight, distance, and freight class.
- Container Fill Rate Calculator — measures what percentage of container capacity is actually utilized by a shipment.
- Last Mile Delivery Cost Calculator — estimates the disproportionately high cost of final-stage delivery to an individual address.
- Logistics Freight Class Calculator — estimates NMFC freight class based on density, handling, and liability factors.
Why Last Mile Delivery Costs So Much More Than the Rest of the Trip
Moving freight in bulk across long distances by truck, rail, or ship is remarkably efficient per unit, but the final leg — delivering an individual package to a specific address — involves stopping repeatedly, navigating residential routes, and handling single packages instead of pallets, which is why last mile delivery commonly accounts for more than half of total shipping cost despite covering only a small fraction of the total distance traveled. This economic reality is exactly why so much logistics innovation (delivery lockers, route optimization, micro-fulfillment centers) specifically targets the last mile rather than long-haul transportation, where efficiency gains are comparatively harder to find.
Frequently Asked Questions
Why does a lightweight but bulky package sometimes cost more to ship than a heavy, compact one?
Because dimensional weight pricing charges based on the greater of actual weight or a size-based calculated weight, so a large, low-density package can be billed at a higher "weight" than its true weight.
Does freight class depend only on weight?
No — density, stowability, handling difficulty, and liability risk (like fragility or value) all factor into NMFC freight classification, which is why two shipments of the same weight can fall into different, differently priced freight classes.
