The number above comes from the inputs you entered, not from a partner.
Reading the result
The figure above is a range, not a quote. It comes from a census of 96 entries collected on 2026-10-05, scaled by the inputs you entered. Where a segment is a published figure rather than a modelled range, the result table says so on the row itself.
A wide range is information rather than noise: it tells you which segment is uncertain. The narrowest ranges on this site are domestic delivery and insurance; the widest are international freight and duty.
What this tool does not do
| Limit |
|---|
| It reflects published carrier announcements, not live capacity. |
| It does not quote a surcharge amount — that depends on weight and lane. |
| Cells without a published announcement are marked open, which is not the same as cheap. |
Limits are stated rather than implied. A tool without stated limits cannot be checked.
Common questions about this tool
| Question | Answer |
|---|---|
| Are the defaults reasonable? | Yes — they are the census medians for the weight band and lane you are most likely to use, and every field is editable. |
| Do the tools store anything? | No. Nothing is written to storage or sent anywhere; the hand-off between tools travels in the address bar. |
| Where do the ranges come from? | The 96-entry census. Each range carries a sample size and a collection date on the census page. |
The method behind every figure is documented on the standards page.
