Free Trucking Calculators for Owner-Operators
Most owner-operators only find out if a load was profitable when the settlement comes in. HaulMath gives you free, fast calculators to price every decision up front — your true cost per mile, whether that $2.40/mile broker rate is worth it, and your break-even point.

Why every mile needs a price tag
Fuel, truck payments, insurance, maintenance, factoring fees — costs pile up quietly while you're rolling. The single habit that separates profitable owner-operators from struggling ones is simple: knowing your cost per mile and refusing loads that price below it. These calculators are free, run entirely in your browser, and never send your numbers anywhere.
Start with the cost per mile calculator — every other number on this site builds on it.
How to use HaulMath (in the right order)
The calculators here work as a sequence, not a grab bag. Start with the cost per mile calculator once a quarter and whenever your costs change — a new truck payment, an insurance renewal, a fuel price that moved more than fifty cents. That single number feeds everything else: it is the "fixed cost per mile" input in the load profit calculator, and it drives the floor in the break-even calculator.
Next, run every broker offer through the load profit calculator before you accept it — not after. Thirty seconds of typing beats a week of regret on a $1.80/mile run that sounded acceptable at 7 a.m. Over a month you will build an instinct for which lanes and which brokers pay, and the calculator becomes a sanity check instead of a lifeline.
Finally, the IFTA calculator and per diem calculator handle the two calendar obligations that quietly drain owner-operators: quarterly fuel taxes and the meal deduction most drivers under-claim. Visit the IFTA tool in the last two weeks of every quarter, and the per diem tool once at year-end before you file.
Everything runs in your browser — no accounts, no data leaving your phone. Bookmark the site on your phone's home screen; most of these numbers get checked in the truck cab, not at a desk.
Trucking money terms, in plain English
You cannot price what you cannot name. These are the twelve terms that decide whether a load, a lane or a whole quarter makes money.
Cost per mile. Every fixed cost (truck payment, insurance, plates, accounting) plus every variable cost (fuel, tires, repairs, tolls) divided by total miles. Run 100,000 miles a year on $175,000 of total cost and the truck costs $1.75 a mile to move — before you pay yourself.
Break-even rate. Your cost per mile restated as the minimum rate per mile that loses nothing. Price 10-15% above it, or one blown radiator erases a month of margin.
Deadhead. Empty miles driven to fetch the next load. A 300-mile deadhead on a 700-mile load paying $2.00/mile drops the effective rate to $1.40 before you count the hours you burned.
Spot market vs contract freight. Spot is one-shot load-board freight, repriced weekly and prone to $0.50-$1.00/mile swings within a season. Contract freight is committed volume at negotiated rates — steadier, and harder to win as a one-truck carrier.
Load-to-truck ratio. Posted loads divided by posted trucks on a lane. Above 5.0, carriers hold the pricing power. Below 2.0, expect the broker to grind.
Fuel surcharge. A rate add-on that tracks diesel prices, usually pegged to a $1.20-$1.30/gallon baseline and adjusted weekly. When diesel jumps $0.40/gallon it can add $0.15-$0.35/mile — money left on the table if you never ask.
Factoring. Selling invoices for same-day cash at a 1-4% discount. Recourse is cheaper; non-recourse costs more but stands between you and a broker who folds owing $9,000.
Detention time. Pay for sitting at a dock, typically $25-$50/hour after two free hours. If it is not written on the rate confirmation, it does not exist.
IFTA. The International Fuel Tax Agreement: one quarterly filing splits your fuel tax across the lower 48 states in proportion to the miles you ran in each. You settle the gap between tax paid at the pump and tax owed where the fuel burned.
Per diem. The IRS meal deduction for nights out — roughly $69-$70 a day at 80% for transportation workers. A 12-night month is about $660 of deduction, and by December that is real money.
Broker. The middleman between shipper and carrier, historically keeping 10-20% of the linehaul. Always ask what the load pays before you quote; the good ones tell you.
Operating authority. Your MC number — FMCSA's permission to haul for hire. It takes a $750,000 liability insurance filing, a BOC-3 process agent and UCR registration before the first wheel turns legally.
Who HaulMath is built for, and how the numbers connect
New authority in year one? Pricing kills more new carriers than driving does. Start with the new authority checklist, then benchmark yourself against the 2026 average cost per mile breakdown so you know whether your numbers are normal or dangerous. Until you have six months of settlements, industry benchmarks are your cost data.
Established operators need a quarterly rhythm, not heroics. Refresh your cost per mile every quarter and whenever a cost changes, feed it to the break-even calculator to reset your floor, and run doubtful offers through the load profit calculator with deadhead and detention included. Cost, floor, verdict — under ten minutes a week, and it is the entire discipline of pricing.
Cash flow runs on the calendar. The factoring and quick-pay guide covers what immediate cash should cost you (typically 1-3%), the IFTA calculator clears each quarterly fuel filing in minutes, and the per diem calculator is worth a run before every tax season — the meal deduction alone commonly saves owner-operators $1,200-$2,000 a year.

FAQ
Are these calculators free?
Yes — all HaulMath tools are completely free. They run in your browser; nothing you enter is stored or transmitted.
Is this tax or financial advice?
No. HaulMath provides estimation tools for planning purposes. For tax decisions, confirm current IRS rules or talk to a CPA who works with truckers.
Can I use these calculators on my phone?
Yes. Every tool on HaulMath runs in your browser and works on a phone screen — no app to install, no account to create. Most owner-operators run the numbers from the cab before accepting a load, which is exactly the point.
How often should I recalculate my numbers?
Recalculate cost per mile and break-even quarterly, plus whenever something big changes: a new truck payment, an insurance renewal, or diesel moving more than $0.25–$0.50/gal from your last update. Load profit should be run fresh on every offer with this week's fuel price.
Do the calculators account for fuel surcharge?
Enter your all-in rate — linehaul plus fuel surcharge — as the broker rate in the load profit calculator. The calculators price what the load actually pays against what it actually costs, so surcharge and linehaul belong in one number.
