TruckMarginThe latest 9.7-cent US diesel increase adds about US$2.33 to a hypothetical 240-mile route at 10 MPG. Preserving a 20% profit margin requires US$2.91 more quoted revenue, with all other costs unchanged. Canada’s higher manufacturing-sales headline also needs context: inflation-adjusted sales were flat.
The US fuel update, with the dates attached
EIA’s October 20 release reports a national on-highway diesel average of US$6.276 per US gallon for October 19, compared with $6.179 on October 12. That is an increase of 9.7 cents per gallon, including taxes. It is a national benchmark, not a promised price at your next fuel stop.
Here is what that change means for two hypothetical 240-mile routes. Distances include all paid and unpaid driving; efficiency is an assumption, not a claim about typical box trucks.
| Fuel economy | Fuel at Oct. 19 benchmark | Increase versus Oct. 12 | Extra quote to preserve a 20% margin |
|---|---|---|---|
| 10 MPG | US$150.62 | US$2.33 | US$2.91 |
| 7 MPG | US$215.18 | US$3.33 | US$4.16 |
Calculated from unrounded inputs, then displayed to cents. The quote adjustments round up. These are fuel-only changes: the original quote is assumed to earn a 20% margin, with every other cost held constant. They are not recommended total route prices or contractual fuel surcharges.
Use a benchmark without letting it replace your numbers
The calculation is straightforward: total miles ÷ your MPG × fuel-price change. If you want to preserve a target profit margin, divide that extra cost by one minus the margin. A 20% margin therefore uses a divisor of 0.80; adding a 20% markup is different.
Before changing a quote, check what the customer already agreed to. A contract may specify a particular benchmark, base price, efficiency factor or update schedule. Recalculate using those terms rather than treating a news headline as permission to add a fee.
Keep two separate figures in your records: the benchmark used in the agreement and the effective price you expect to pay. A pump discount changes the latter, but does not automatically change the former. Enter the appropriate figure for the decision you are making, and label it so a future review makes sense.
Canada: a higher sales total is not automatically more freight
Statistics Canada’s October 15 release covers August, not this week. Manufacturing sales increased 1.5% to C$79.9 billion, but sales measured in constant dollars were unchanged. Transportation-equipment sales declined 2.6%. The next advance estimate, covering September, is scheduled for October 23.
Our interpretation: this is a reason to examine the industries you serve, not evidence that every carrier should expect more loads. Dollar sales can rise because prices rise. Neither the national total nor one subsector’s result tells you how many profitable jobs a particular customer will book. These statistics are also subject to revision.
Turn the headlines into three operating decisions
First, refresh the inputs that actually changed. Record the price, currency, fuel unit and date together. US dollars per US gallon do not belong in a Canadian-dollars-per-litre calculation without explicit currency and unit conversion. Use your own Canadian purchase prices for Canadian jobs; this brief supplies no Canadian diesel-price estimate.
Second, ask your customers about their upcoming work. Check route frequency, confirmed stops, expected volume and the likelihood of a return load. Treat a national industry indicator as background for that conversation, not as a replacement for a booking.
Third, compare the next completed job with its quote. Record actual distance, time, revenue and costs, while keeping the original assumptions. That comparison tells you whether a fuel change, an inaccurate time estimate or some other input deserves attention next time. It does not prove a cause by itself.
Use the free delivery-pricing calculator to test a route. In Pro, save the assumptions with the quote and enter the result afterward. The useful question is which input changes the decision you face today.
