About this calculator
Apply a user-entered U.S. hundredweight rate to prepared billable shipment weight. Each shipment has its own discount and absolute net minimum, so separately billed shipments remain separate rows.
Inputs
How to use this calculator
Separate shipment
- Prepared billable shipment weight (lb)Use the weight already prepared under your agreement; this page does not determine class, deficit weight or dimensional-weight rules.
- Rate per U.S. short hundredweight (CWT; USD/100 lb)One U.S. short hundredweight equals 100 lb. This is not a metric or long hundredweight.
- Discount off weight-rate charge (%)Enter 0–100%. This model applies the discount before the net minimum.
- Absolute net minimum charge (USD)A floor applied after the discount, not a tariff minimum applied before it.
Enter the shipment or scenario values, then select Calculate result.
Method
Formula and variables
Short hundredweight units = prepared billable pounds ÷ 100. Per-shipment charge = the greater of (short hundredweight units × entered rate × (1 − discount ÷ 100)) and the absolute net minimum. Add separately billed shipments.

Interpret the result
The charge applies the discount before the net minimum. It does not determine class, deficit weight or dimensional weight, and it excludes fuel and accessorial charges not entered here.
Outputs: Net charge by shipment and combined total
Requires prepared billable weight and an applicable entered rate. No class, zone, deficit weight, tariff minimum before discount, fuel, accessorials or live agreement is inferred. Use the deficit planner separately when an agreement permits higher-break rating. Display rounding does not verify an invoice.
Worked example
Check the arithmetic
This example uses the starting values shown above. The arithmetic below is calculated independently of the interactive result.
Work through the calculation
- 1,500 lb ÷ 100 lb per short hundredweight = 15 billing units.
- Weight-rate charge = 15 × $15 = $225; after a 20% discount, $225 × 0.80 = $180.
- The greater of $180 and the $100 net minimum is $180.
Compare the displayed result
Expected displayed result: $180.00
FAQs
Is the entered minimum discounted?
No. This model treats it as an absolute net floor after discount. A tariff minimum with another sequence needs different governing terms.
