American Iron × Financial Precision
Know your numbers.
Take control.
What a mile really costs, what a load really paid, and what is left at the end of the week.
The calculator is free and needs no account.
- Real costsWhat a mile actually costs you
- Load profitWhat each load truly cleared
- FuelThe MPG your truck really gets
- Tax readyRecords your accountant can use
- On your phoneIn the cab, at the truck stop
Loads
Every load has a number.
Know yours.
Gross pay is not profit. ProfitRig takes the fuel, the tolls, the lumpers and that load's share of your monthly bills off the top, and shows you what was actually left.
- Log a load in under a minute, from the cab.
- A loss is named a loss — never hidden in a colour.
- Monday-to-Sunday weeks that match how you get settled.

The Loads ledger, as it appears on a wide screen. On a phone each load becomes a card.

Fuel
Every tenth of an MPG matters.
Log your odometer and the gallons you bought. ProfitRig works out the miles per gallon your truck really gets — not the number on the spec sheet — and feeds it straight into your cost per mile.
- One entry a week is enough.
- A tenth of an MPG is real money at 10,000 miles a month.
- Your real MPG, not an estimate, behind every load's cost.

Tax
Tax time shouldn't be a scavenger hunt.
Expenses categorised as you go, per diem nights counted, and capital purchases kept separate — so the year-end report is something you hand over, not something you assemble.
- Receipts logged in the cab, not in a shoebox.
- Capital purchases kept apart from running costs.
- A clean year-end report to hand your accountant.
ProfitRig keeps organised records. It is not tax advice, and it does not file anything for you.
On your phone
Get ProfitRig on your phone.
ProfitRig installs straight from the browser — no app store, no download, no account required to try the calculator. It opens full screen and sits on your home screen with your other apps.
- Log a load at the dock, not at the kitchen table.
- Built for one hand and a cold morning: 44px targets throughout.
- Same numbers on the phone and the laptop.
