Flat amount
A fixed dollar amount every time the accessorial applies — the simplest charge type.
Accessorial pricing
Every charge type, priced exactly like your tariff.
TruckMath reads a carrier's rules tariff and turns every accessorial into a plain-English, editable calculation — no raw JSON, no guesswork. Here is every charge type it supports, shown with real examples from a live ODFL tariff.
One page, every accessorial
A sortable, searchable, filterable list of every active accessorial for your carrier — code, name, tariff item reference, and a plain-English description of how each one calculates.

ZIP tables that scale to hundreds of ZIPs
Rules tariffs price some accessorials by ZIP code — sometimes hundreds of them. TruckMath groups ZIPs by price instead of listing one row per ZIP, so a 405-ZIP table stays editable as a handful of price groups.
