CWT Shipping Rate Calculator

About the CWT Shipping Rate Calculator

Hundredweight (CWT) pricing is a volume discount program offered by UPS, FedEx, and other carriers for shippers sending multiple packages to the same destination on the same day. Instead of pricing each package individually, CWT rates charge per 100 pounds (hence "hundredweight") with significantly lower per-package costs.

CWT pricing typically requires a minimum of 200 lbs per shipment (multiple packages to the same address) and uses the total shipment weight for rating rather than individual package weights. This is ideal for B2B shipments, retail replenishment, and distributors who regularly ship multiple cartons to the same location.

This calculator estimates CWT shipping costs and compares them to individual package rates, helping you identify when CWT pricing delivers the most savings.

Use the result to compare operating scenarios, pressure-test assumptions, and rerun the model when volumes, rates, or service targets change.

When This Page Helps

CWT pricing can reduce shipping costs by 30-60% compared to individual package rates. However, it only makes sense when you're shipping multiple packages to the same address on the same day and meeting the minimum weight requirement. This calculator helps you determine when CWT pricing is advantageous.

How to Use the Inputs

1. Enter the total shipment weight in pounds.
2. Enter the CWT rate (price per 100 pounds).
3. Enter the number of packages in the shipment.
4. Optionally enter the individual package rate for comparison.
5. View the CWT cost and per-package savings.
6. Determine if CWT pricing is more economical for your shipment.

Example Calculation

Tips & Best Practices

• Consolidate orders to the same address and ship on the same day to qualify for CWT.
• CWT minimums are typically 200 lbs — plan shipments to exceed this threshold.
• Negotiate CWT rates separately from your standard parcel rates for maximum savings.
• CWT works best for B2B shipments with multiple cartons going to stores, warehouses, or offices.
• Compare CWT vs LTL for heavier multi-package shipments — LTL may be cheaper over 500 lbs.
• Track your CWT-eligible shipments — many shippers miss opportunities by not identifying qualifying packages.

When to Use CWT vs Individual Package Rates

CWT pricing shines when you have 3+ packages totaling 200+ lbs going to the same address. For single-package shipments or very light multi-package shipments, individual rates may be cheaper. Calculate both ways to find the crossover point for your typical shipment profiles.

CWT in Retail Distribution

Retail replenishment is the classic CWT use case. A distributor shipping 10-20 cartons to each retail store location on a weekly basis benefits enormously from CWT pricing. The combined weight easily exceeds minimums, and the per-package cost drops dramatically compared to individual rating.

Optimizing CWT Shipments

To maximize CWT savings, consolidate orders to the same destination into single-day shipments. Use your TMS or shipping software to identify CWT-eligible packages and group them automatically. Track CWT utilization metrics to ensure you're capturing all qualifying shipments.

Frequently Asked Questions

• What is hundredweight (CWT) pricing?

  CWT pricing charges per 100 pounds of combined weight for multi-package shipments to the same address. Instead of rating each package individually, the carrier rates the total shipment weight at a lower per-CWT rate, providing significant volume savings.

• What are the requirements for CWT pricing?

  Typical requirements include a minimum of 200 lbs per shipment, multiple packages going to the same address on the same day, and an enrolled CWT pricing agreement with the carrier. Some programs require a minimum of 3 or more packages.

• How much can I save with CWT pricing?

  CWT pricing typically saves 30-60% compared to individual package rates. Savings are greatest for heavier multi-package shipments to nearby zones. The exact savings depend on your negotiated CWT rates and individual package rates.

• Is CWT better than LTL?

  For shipments of 200-500 lbs, CWT ground is often cheaper and faster than LTL because it uses the parcel network. Above 500 lbs, LTL may become more economical. Compare both for your specific weight and lane.

• Do fuel surcharges apply to CWT?

  Yes. Fuel surcharges are applied to the CWT rate, typically as a percentage of the total charge. CWT fuel surcharges may be different from standard parcel fuel surcharges, so verify your rate card.

• Can I use CWT for residential deliveries?

  CWT pricing is primarily designed for commercial addresses. Some carriers allow CWT for residential deliveries but may apply a residential surcharge per package on top of the CWT rate, reducing the savings.
