Why Most SA Fleet Operators Underestimate Their Costs
Ask ten South African fleet operators what it costs to run their trucks per kilometre, and you'll get ten different answers — most of them wrong. The Road Freight Association's annual cost benchmarking consistently shows that operators underestimate their true costs by 15-25%.
This isn't ignorance; it's complexity. Running a truck fleet in South Africa involves dozens of cost categories, many of which are invisible on a per-trip basis but devastating over a financial year.
Fixed Costs: What You Pay Whether the Wheels Turn or Not
Vehicle Finance or Depreciation
A new long-haul truck-tractor in South Africa costs between R1.8 million and R3.5 million depending on the brand and specifications. A flatbed or tautliner trailer adds another R450,000-R850,000. Monthly instalments on a financed unit typically run R45,000-R75,000.
Even if you own your vehicles outright, depreciation is real. A truck loses approximately 15-20% of its value per year for the first five years.
Insurance
Comprehensive fleet insurance in South Africa ranges from R8,000-R18,000 per vehicle per month, depending on the vehicle value, claims history, routes operated, and cargo type. Goods-in-transit insurance adds another layer of cost.
Licensing and Compliance
Annual licensing for a heavy vehicle in Gauteng costs approximately R8,500-R12,000. Add operating permits, cross-border permits (if applicable), and annual roadworthy certificates. Budget roughly R1,500-R2,500 per vehicle per month for licensing and compliance.
Tracking and Technology
Fleet tracking systems cost between R350-R800 per vehicle per month. While this seems small, it adds up across a fleet. However, it's non-negotiable — insurance companies require it, and the operational visibility it provides pays for itself many times over.
Variable Costs: The Per-Kilometre Reality
Fuel — The Biggest Line Item
Fuel typically accounts for 35-42% of total operating costs. In early 2026, 50ppm diesel prices hover around R24.00-R25.00 per litre in Gauteng. For a truck averaging 2.2-2.8 km/litre, that translates to:
- Best case: R8.57/km (2.8 km/l at R24.00/l)
- Worst case: R11.36/km (2.2 km/l at R25.00/l)
- Average: R9.50-R10.50/km
Tyres
A full set of tyres for a truck-tractor and trailer (typically 34-38 tyres) represents an investment of R120,000-R180,000. With an average tyre life of 80,000-120,000 km, tyre costs work out to roughly R0.75-R1.20/km.
Retreadable casings can reduce this cost by 30-40%, making tyre management a genuine profit lever.
Maintenance and Repairs
Planned maintenance on a well-managed fleet costs approximately R0.60-R0.90/km. Unplanned repairs can double or triple this figure. Fleet age is the critical variable — trucks older than 5 years typically cost 40-60% more to maintain than newer units.
Tolls
South Africa's toll road network significantly impacts route costs. Key toll costs for heavy vehicles:
- N1 JHB-CPT: R1,200-R1,800 one way
- N3 JHB-DBN: R800-R1,200 one way
- N4 JHB-Nelspruit: R600-R900 one way
- Gauteng e-toll (if operational): Ongoing cost for Gauteng-based operations
Toll costs can add R0.50-R1.30/km depending on the route.
Driver Costs
The National Bargaining Council for the Road Freight and Logistics Industry sets minimum wages. A long-haul driver's total cost to the company (salary, UIF, leave, overnight allowances, bonuses) typically works out to R25,000-R40,000 per month, or roughly R1.50-R3.00/km depending on monthly distances covered.
The Full Picture: Cost Per Kilometre for 2026
Bringing it all together for a typical long-haul operation:
- Fuel: R9.50-R10.50/km
- Tyres: R0.75-R1.20/km
- Maintenance: R0.60-R1.50/km
- Tolls: R0.50-R1.30/km
- Driver costs: R1.50-R3.00/km
- Insurance: R0.60-R1.20/km
- Finance/depreciation: R2.00-R4.00/km
- Licensing/compliance: R0.15-R0.25/km
- Administration/overheads: R0.80-R1.50/km
Total estimated cost: R16.40-R24.45/km
The wide range reflects differences in fleet age, utilisation rates, route profiles, and management efficiency. Knowing where your fleet falls on this spectrum is critical to pricing profitably.
How to Calculate YOUR Cost Per Kilometre
Generic industry benchmarks are useful as a reference, but your fleet is unique. Here's how to calculate your actual costs:
Step 1: Gather 3 Months of Data
Collect all invoices, fuel slips, payroll records, and maintenance receipts for a minimum of three months. The more data, the more accurate your calculation.
Step 2: Categorise Every Expense
Sort expenses into fixed (monthly regardless of distance) and variable (per kilometre or per trip). This distinction is crucial for accurate quoting.
Step 3: Calculate Total Kilometres
Use your tracking system to get accurate total kilometres per vehicle per month. Don't estimate — even 10% inaccuracy in distance throws off your entire cost model.
Step 4: Use Technology to Automate
Manual cost tracking is tedious and error-prone. TruckWys Fleet Performance automatically captures and categorises costs, giving you real-time cost per kilometre visibility across your entire fleet.
Why This Matters for Your Bottom Line
If you're quoting freight at R18/km but your true cost is R22/km, you're losing R4 on every kilometre. On a JHB-CPT trip of 1,400 km, that's R5,600 lost per trip. Do 10 of those a month, and you're haemorrhaging R56,000 monthly — R672,000 per year.
Knowing your true cost per kilometre isn't just accounting — it's the foundation of a profitable fleet. Start tracking your real costs with TruckWys today.
