Hot shot load math is only useful when the inputs come from current records: the rate confirmation, written contract, route plan, fuel-card data, settlement terms, equipment ratings, insurance, maintenance reserve, and accounting records.
This guide frames the source gaps behind the Hot Shot Trucking Profitability Calculator. It does not publish live rate guidance, legal conclusions, CDL approval, dispatch advice, or accounting advice.
Use the calculator to make assumptions visible, then verify every material input before accepting, quoting, financing, or dispatching a load.
CDL Boundary Source Gap
FMCSA source pointers provide the federal CDL class context, but the calculator does not decide whether a driver, vehicle combination, cargo, endorsement, exemption, or state-specific requirement is legal.
Before dispatch, verify GVWR, GCWR, actual gross vehicle weight, trailer rating, axle weights, cargo, hazardous-material status, medical-card requirements, insurance terms, state rules, and enforcement facts with qualified review.
Treat the app prompt as a review trigger. It is not a license-class determination, DOT inspection defense, insurance approval, or substitute for carrier compliance controls.
Deadhead and Paid-Mile Basis
Deadhead is a source gap because empty miles still consume fuel, maintenance reserve, tires, insurance exposure, equipment life, driver time, and HOS capacity. The loaded-mile rate alone does not show the total-mile economics.
Use actual route miles, paid miles, unpaid repositioning miles, tolls, fuel stops, and backhaul assumptions. Then compare both loaded-mile and total-mile results against your own cost stack and target margin.
The calculator can show the arithmetic, but it does not verify the route, guarantee a backhaul, decide whether a lane is good, or provide rate-market advice.
Fuel Surcharge Source Gap
EIA source material describes diesel fuel surcharge concepts, but actual FSC billing is controlled by written shipper, broker, carrier, or lease terms.
Verify the base diesel price, index source, update interval, MPG basis, loaded-mile or total-mile basis, step matrix, caps, minimums, pass-through treatment, and whether driver percentage pay includes FSC revenue.
The Fuel Surcharge Calculator can model patterns. It does not override contract language, settlements, tax treatment, or carrier policy.
Rig Move Accessorial Source Gap
Rig-move work can involve field hours, standby, layover, oversize permits, escorts, mobilization, site access, and pass-through costs. The app rows are placeholders for those terms, not basin rate guidance.
Use the written operator contract, dispatch sheet, permit requirements, escort rules, route restrictions, site safety rules, insurance endorsements, and settlement terms to populate the rows.
Do not treat blended per-mile output as a market quote unless current customer terms, field conditions, and qualified review support it.
Rate Source Gap
There is no generic good rate that is safe to publish for every truck, lane, market, season, contract, and authority status. A rate that works for one operator can fail for another because fixed costs, insurance, deadhead, driver pay, maintenance reserve, and finance terms differ.
Validate rates against current lane data, direct customer terms, broker confirmations, load-board data you are licensed to use, fuel price, actual cost records, and target margin. Keep those records with the quote.
The app verdict tiers are local screening thresholds. They are not live market rates, a recommendation to accept or reject freight, or proof of profitability.
