Semi Truck Operating Cost per Kilometre in Canada

Choose the cost question first

Use the same time period and tax basis throughout. Work in CAD, kilometres, litres and L/100 km. State whether tax amounts are recoverable or included, and keep one-off acquisition cash separate from recurring operation.

Worked cash-flow example you can recalculate

Illustrative annual assumptions: 160,000 total km, 38 L/100 km and diesel at $1.65/L. These are chosen inputs, not sourced averages. Fuel is 60,800 L × $1.65 = $100,320. Driver compensation includes the employer costs or owner draw allowance you choose to budget.

Use the ownership calculator with the same categories

Enter $28,000 for maintenance and tyres and $30,000 for insurance, registration and other fixed costs to reproduce the grouped inputs. The calculator includes a separate driver-compensation field. Add DEF, consumables, trailer costs, tolls or other costs to the appropriate allowance where relevant; it does not fetch them automatically. If idling fuel is excluded from your L/100 km observation, add it with the fuel calculator and carry the resulting fuel estimate into your plan. Do not add it again if the recorded consumption already includes idling.

Change annual kilometres and fuel assumptions

At the same consumption and fuel price, fuel costs $0.627/km. Hold the other illustrative annual allowances constant only for this sensitivity exercise: $159,600 ÷ 160,000 km = $0.9975/km for all non-fuel categories. At 120,000 km that allocation rises to $1.33/km, making $1.957/km total. Real tyre, maintenance and labour costs may also change with activity; rebuild those allowances when the operation changes.

• A $0.10/L diesel increase at 38 L/100 km adds $0.038/km, or $6,080 over 160,000 km.
• An extra 1 L/100 km at $1.65/L adds $0.0165/km, or $2,640 annually at 160,000 km.
• Budget seasonal consumption and unpaid travel separately when their operating conditions differ from highway cruising.

Treat owner labour and downtime explicitly

For an owner-operator, show both cash drawn and the compensation needed to replace your work. A plan with no wage draw can be cash-positive while failing to compensate the owner. Budget shop days, relief or replacement equipment, and delayed customer receipts. Reduce expected kilometres for downtime and include any replacement costs; do not automatically add lost revenue as an expense to a calculation that already assumes fewer paid kilometres.

Economic cost: replace principal, then add depreciation

Suppose the example’s $21,600 annual payments contain $16,000 principal and $5,600 interest according to the actual loan schedule. If separately estimated annual depreciation is $18,000, economic cost before any additional capital charge would be $259,920 − $16,000 + $18,000 = $261,920, or $1.637/km. The interest remains included. Those principal and depreciation amounts are illustrative, not inferred from a truck’s badge or an asking-price sample. An outright-owned truck can have depreciation even with no loan payment.

Paid kilometres and break-even revenue

If only 85% of the example’s 160,000 km earns distance-based revenue, there are 136,000 paid km. The cash plan needs $259,920 ÷ 136,000 = about $1.9112 per paid km to cover the included outlay. This leaves no added profit margin, contingency or omitted costs. Rate structures, fuel surcharges, waiting time and collections also matter. Test the whole contract rather than treating this result as a freight-rate recommendation.

Replace illustrations with evidence from your operation

Use fuel litres and odometer totals, maintenance invoices, a tyre-replacement plan, insurance and permit quotations, the actual amortization schedule and a realistic work calendar. Identify which entries are estimates, update them when evidence arrives, and compare costs for matched duty cycles. The manufacturer name alone does not establish a truck’s cost per kilometre.
