Load profit = operating revenue for the load minus direct load costs minus allocated fixed costs. Use every mile, not just paid miles, and close the numbers after delivery instead of relying on the original rate confirmation.
A load can put cash in the bank and still be a weak run. The linehaul rate may look fine while deadhead, tolls, parking, a lumper fee and two days of truck overhead eat the margin. That is why revenue per load is not enough.
Per-load profit gives an owner-operator a useful operating view. It helps compare lanes, customers and dispatch decisions using the same method. It is not a replacement for monthly bookkeeping or a tax return. Think of it as the trip-level layer between a rate confirmation and the company books.
Use one formula for every load
Keep the formula simple enough to complete from the cab:
Load profit = total load revenue - direct load costs - allocated fixed costs
Profit per total mile = load profit / all miles driven for the load
Load margin = load profit / total load revenue × 100
"All miles" means the miles from your starting position through final delivery, including deadhead. If the next pickup requires repositioning that belongs to the current business decision, track that separately and apply one consistent policy. Consistency matters more than making one load look good.
Step 1: record every dollar of load revenue
Start with the final settlement, not only the booked linehaul amount. Create separate fields for:
- linehaul revenue;
- fuel surcharge;
- detention, layover or truck ordered not used payments;
- stop pay and other accessorial revenue;
- any adjustment, chargeback or short payment.
Separating these items makes the lane easier to evaluate later. A run that works only because of detention is different from a run with a strong base rate. Keep both the planned revenue and the amount actually paid so settlement errors stand out.
Step 2: count paid miles and deadhead
Rate per paid mile answers one question: what did the carrier pay for the loaded movement? Profit per total mile answers the harder question: what did the truck earn across every mile required to complete the work?
| Mileage field | What to enter | Why it matters |
|---|---|---|
| Paid miles | Miles covered by the rate agreement | Useful for checking the booked rate |
| Deadhead to pickup | Unpaid miles driven before loading | Shows the cost of reaching the freight |
| Other load miles | Unpaid route, service or repositioning miles assigned to the load | Prevents mileage from disappearing |
| Total miles | Paid miles plus all assigned unpaid miles | Provides the denominator for true operating performance |
Do not switch between dispatch miles and odometer miles without noting the difference. Odometer readings are usually the cleanest operational record because they show what the truck actually traveled.
Step 3: attach direct costs to the load
Direct costs move with the trip. Record them as soon as they happen:
- fuel purchased or fuel consumed for the load;
- tolls, scales, parking and permits tied to the movement;
- lumper, unloading and washout fees;
- dispatch or factoring fees that apply to the load;
- repairs caused by a specific trip, when assigning them directly is reasonable.
Fuel is the line most likely to distort a quick estimate. For a fast operating calculation, use gallons consumed multiplied by your actual average purchase price. Gallons consumed can be estimated from total load miles divided by the truck's recent miles per gallon. Reconcile that estimate against fuel receipts and actual fleet records each week.
The U.S. Energy Information Administration publishes weekly on-highway diesel prices by region. That data is useful for planning, but your receipts are the right source for closing a load because discounts, taxes and location change the price you actually paid.
Step 4: give the load its share of fixed costs
A truck payment does not appear on a rate confirmation, but the load still has to carry it. The same is true for insurance, base plates, subscriptions and other costs that continue when the truck is parked.
Choose one allocation method and keep it stable:
- Per operating day: monthly fixed costs divided by planned operating days, multiplied by the number of days used by the load.
- Per total mile: monthly fixed costs divided by planned monthly miles, multiplied by total load miles.
The day method is easier when loads regularly consume full days. The mileage method can work better for dense regional operations. Review the planned denominator against actual days or miles at month-end. Otherwise, an optimistic mileage target will understate the fixed cost on every trip.
Do not count the same expense twice. If a maintenance reserve is included as a per-mile cost, do not also allocate that same maintenance amount through monthly overhead.
A worked example
This is an illustrative load, not an earnings claim. Replace every number with your own settlement, receipts and cost structure.
| Item | Calculation | Amount |
|---|---|---|
| Total revenue | $2,800 linehaul + $350 fuel surcharge + $150 detention | $3,300 |
| Fuel | 185 gallons × $3.80 | $703 |
| Other direct costs | $95 tolls + $60 lumper + $25 parking + $224 dispatch fee | $404 |
| Allocated fixed costs | $6,200 monthly fixed costs / 20 operating days × 2 days | $620 |
| Load profit | $3,300 - $1,107 - $620 | $1,573 |
The truck ran 1,200 total miles: 1,100 paid and 100 deadhead. The result is $1.31 profit per total mile and a 47.7% operating margin in this hypothetical example. If you divide by paid miles instead, the result looks better but hides the 100 miles required to reach the freight.
Close each load in five minutes
The math is not the hard part. The hard part is collecting the details before receipts disappear and the next dispatch takes over. Use a short closeout routine after proof of delivery:
- Enter the final odometer reading and total miles.
- Photograph or upload fuel, toll, scale, parking and lumper receipts.
- Record accessorials owed and flag anything not yet approved.
- Apply the same fixed-cost rule used on every other load.
- Mark the record estimated until the settlement arrives, then replace estimates with actual amounts.
A weekly review should compare the planned rate with the final settlement, clear missing receipts and check whether any cost category was skipped. The broader mobile business workflow for truck drivers explains how trip, expense and compliance records fit together. If business and personal transactions are mixed, fix that layer too with the personal and business bookkeeping guide.
Use the result to improve decisions
One load does not prove that a lane is good or bad. Weather, detention and maintenance can make a single trip unusual. Look for patterns across several completed loads:
- profit per total mile by lane and customer;
- deadhead percentage by pickup area;
- planned revenue versus final settlement;
- fuel cost per total mile;
- loads with repeated accessorial delays or unpaid charges.
Those patterns are useful during rate preparation and dispatch planning. They also reveal whether a lane produces cash while quietly consuming too much truck time.
Keep the tax record separate from the operating view
This worksheet is for management decisions. Tax reporting may classify expenses differently, require depreciation treatment or ask for supporting vehicle information. The IRS Schedule C instructions state that taxpayers claiming car and truck expenses must provide specified vehicle-use information. IRS Publication 463 also explains substantiation and timely recordkeeping for covered travel and vehicle expenses.
Keep settlement statements, receipts, mileage records and notes that establish the business purpose of an expense. Ask a qualified tax professional how the rules apply to your equipment, entity and filing method. This guide is general business information, not tax, legal or compliance advice.
