How Do You Calculate Dollars Per Hour on a Load?

What does dollars per hour measure on a load?

Rate per mile prices the distance. Dollars per hour prices the day. They are not the same question, because a load doesn’t just consume miles — it consumes a fixed, non-refundable 14-hour window, and some loads spend that window far more carelessly than others. The formula is one division:

$/hour = netProfit ÷ estimatedHours

The numerator is net profit — what you actually keep after fuel for every mile driven, fixed and variable cost per mile, percentage fees, tolls, and the rest. That chain is its own page: how do I calculate load profitability end to end? The denominator is the estimated hours the load consumes — not just the driving, but the loading, the unloading, and the hours nobody pays you for. LoadWizz shows estimated dollars per hour on every load — net profit divided by estimated route hours.

netProfit = rate − totalExpenses

Both halves matter equally. Inflate the numerator with napkin math and the number lies one way; forget the dock hours in the denominator and it lies the other way. Say “estimated” every time — hours and dollars-per-hour are forecasts until the day is over.

How do you estimate the hours a load consumes?

Two components, added:

estimatedHours = estimated drive hours + dock hours

Estimated drive hours come from the route duration or from an average-speed estimate over the total miles — loaded and deadhead both, because the truck doesn’t know the difference and neither does the clock. Dock hours are the honest guess for pickup and delivery combined: a drop-and-hook might cost half an hour, a live load at a grocery warehouse can cost four. Deadhead deserves particular respect here — it adds hours and cost while adding nothing to the rate. The cost side of that is covered in how much do deadhead miles really cost?

Why does the same net profit pay $24 or $14 an hour?

Because the denominator moves and the numerator doesn’t. The same net profit, stretched over more hours, simply pays less per hour — there is no trick to it, only arithmetic most napkins never run:

That $194 column is not hypothetical. On July 11, 2026, a real $1,350 load from Erie, PA through Buffalo, NY to Boston, MA — 458 loaded plus 93 deadhead miles, $210 in tolls, 7.5 MPG, EIA diesel at $4.578/gal, 3% dispatch plus 3% factoring, $0.96/mi operating costs, 1.5 hours at the dock — worked out like this: fuel ≈ $336 (551 miles ÷ 7.5 MPG × $4.578), fees $81, operating $528.96, tolls $210. Napkin math (rate minus fuel and tolls) said +$804, roughly $64/hr estimated. The full math said +$194, about $15.50/hr estimated over 12.5 on-duty hours — a $610 gap between the broker’s napkin and what you actually keep. Same load, same day, same 12.5 hours; the only difference was which costs got counted.

Can a lower rate per mile beat a higher one inside a 14-hour window?

Routinely. You are paid by the mile, capped by the hour: HOS gives you one 14-hour on-duty window per shift, and every load spends it differently. A $3.30 load with two live docks can hand the day back to you thinner than a $2.45 load that rolls. Two illustrative loads, each fitting inside one window:

The math behind the two nets: Load A drives 240 miles, so expenses are 240 × $1.55 + 6% × $660 = $411.60, leaving $248.40; Load B drives 505 miles, so expenses are 505 × $1.55 + 6% × $1,176 = $853.31, leaving $322.69. Load A wins the rate-per-mile contest by 85 cents and still loses the day: five hours at the docks buys nothing, and the estimated hourly rate lands about $2.50/hr lower. Whether the winner is worth saying yes to at all is a separate decision — when should you reject a load? walks that one, and what profit margin should a truckload leave? prices the margin side.

How does detention pay actually work?

Detention is the industry’s partial answer to unpaid dock hours: an hourly fee the carrier bills when a shipper or receiver holds the truck past an agreed free window. It is a negotiation and a paperwork discipline between you and the broker or shipper — not an automatic payment, and not something any calculator can promise you. The mechanism has three parts:

The scale of the problem is documented. The U.S. DOT Office of Inspector General’s 2018 audit estimated that detention is associated with reductions in annual earnings of $1.1 billion to $1.3 billion for for-hire truckload drivers — between $1,281 and $1,534 per driver per year, a 3.0 to 3.6 percent cut in average annual income. The same audit estimated that a 15-minute increase in average dwell time raises the expected crash rate by 6.2 percent. Two practical consequences follow. First: dock hours belong in your estimated hours whether or not detention ever pays — plan the load on the honest denominator, and treat collected detention as recovery, not revenue you can count on. Second: the paper trail is the pay. In/out times, every time.

One number, one division, one habit: before you say yes, ask what the load pays for the hours it takes — not just the miles it covers. Sometimes “no” is the most profitable word you’ll say all week. More of the math lives in the Learn library.
