Boom or Bust: Costing Road Freight Operations

Boom or Bust: Costing Road Freight Operations

Costing road freight operations can be a formidable undertaking, but the extent to which operators get it right can make or break the business. NICK PORÉE unpacks the intricacies of these critical procedures.

There is a quote from an Australian “truckie” that aptly sums up the pressures of managing one’s own transport  operations: “When I worked for a firm, I was pressured and stressed, but since I started my own trucking business I sleep like a baby… I wake up every three hours, crying.”

Costs vs Expenses

In any discussion of costing road freight transport operations, we must make the distinction between “costs” (which are incurred as a continual but unseen process) and “expenditure” (orders, invoices and payments). A new or quality used vehicle may run for some time requiring only payments for fuel and some servicing. It may seem to make a handsome profit.

There are, however, costs of wear and usage that will only turn into payments later when tyres need to be replaced, the clutch needs to be overhauled and other work is required. A set of tyres for a five-axle combination, for example, costs around R100,000; a clutch overhaul in 2025 could set you back as much as R90,000 for spare, repairs, tools and downtime. Many of the “fixed” costs only turn into expenses at regular or irregular intervals, including insurance, hire purchase (HP), utility costs, licences and rentals. Failure to recognise the difference between costs and expenses is a frequent reason for the demise of new transport businesses.

To prepare for these “hidden” costs, we must use a standard-based costing system when quoting or budgeting for transport operations. The standard cost must be a combination of variable costs for distance run, (rand/km) and fixed cost in rand per hour. The standard costs can be calculated or derived from industry figures, but must cover the full long-term operating costs of the vehicle/s used and the total fixed costs of the transport business. The apparent initial “excess profit” must be banked or invested in a separate contingency account and not used for any external purpose until the operating costs inevitably turn into invoices and payments. 

There are several necessary administrative procedures to control this process. Firstly, detailed records of expenses (including goods ordered not paid) must be kept in a set of management accounts. These accounts must record variable expenses by vehicle and fixed costs by vehicle category. In order to relate these costs to work done and payments received, one should keep records and produce monthly statements which relate the costs and expenses for the work performed.

Each vehicle’s kilometres and hours worked for each operation, every day – including load, trip and customer (as well as “dead” kilometres, not chargeable) must be recorded in detail. The analysis of vehicle operations must include load weights, capacity utilisation and time utilisation for loading, travel and unloading, as well as standing times.

Analysis of the management accounts gives us vehicle costs per kilometre and the fixed costs per hour worked. We can then produce a performance analysis that shows the costs per vehicle and costs of each operation, as well as the variance as profit or loss.

This monthly process is essential for the management of road freight operations, as it is not possible to effectively control operations using only annual financial statements. It should further be noted that this process is equally relevant for hire and reward operations, as well as in-house transport operations.

Depending on the size of the business, these processes can be done manually in a simple computer program, or by one of the many electronic fleet management programs available. The important consideration is to ensure that the monthly information is condensed and presented in a format that allows a busy operations manager to efficiently make decisions to manage the activities.

If too much data is produced by the system, there is a danger of “information overload”. This must be countered by daily and monthly analysis of key performance indicators (KPIs) against budgeted performance parameters – for instance, load percentage, km/load, percentage standing time and loads per day. The daily report should not just be reams of figures; it should be concise and focused by operation, shift and vehicle category. It must also highlight areas of sub-standard performance and, crucially, contribute to direct management action.

Fixed and Variable Costs

It is important to identify the fixed and variable costs of doing business, as they behave differently and many accrue invisibly but inexorably over time.

“Fixed costs” are cost items incurred over time, irrespective of whether or not there are operations. These include:

  • The depreciation of vehicles and other assets.
  • Annual vehicle (and any other) licence fees.
  • Driver costs, such as benefits, bonuses, pension funds, UIF, leave and sick pay.
  • Business, vehicle, load and driver insurance.
  • Bank and accounting charges, as well as interest on capital employed in the business.
  • Supervision and management costs.
  • Cost of utilities (electricity, water, premises maintenance).
  • Overheads (office, staff vehicles and external charges like accountants or legal fees).
  • Vehicle finance charges (HP, loaned finance, extended repayments).
  • Any other costs that accrue over time.

For budget purposes, the total annual fixed costs should be calculated in order to enable an estimated cost per hour of vehicle operations for the estimated chargeable hours of work, as explained below. For mixed fleets, it will be necessary to make assumptions, estimates and allocations. For hire and reward operations, add the percentage mark-up required as profit from operations.

Variable vehicle costs include fuels and lubricants; tyres (new and retreaded); maintenance (cost of workshop labour – in-house or outsourced); spares (cost of parts, including damage and accident repairs); and extras like tarps, ropes and jacks. Variable operating costs, meanwhile, include tolls; fees, levies and permits; and fines, bribes and “arrangements”. Some of these costs may need to be estimated – for example, costs relating to cross-border or transport-corridor operations.

Full operating cost standards must be calculated or researched for all vehicles engaged in chargeable transport operations.

Calculating Operations Costs  

Fixed costs: When working out fixed operations costs, operators must:

  • Consider all fixed costs listed in the section above.
  • Calculate depreciation based on the current value of both new and used vehicles (include onboard equipment such as reefers, mixers and discharge). Work out the depreciation period in years, the percentage to be depreciated, and the residual value after depreciation.
  • Consider the value of the prime mover (less tyres)
  • Estimate annual hours worked, then chargeable hours
    • (e.g. 300 days/year x 10hrs/day = 3,000hrs – 15% vehicle downtime = 2,550hrs – 20% no work days = 2,040hrs)

  • Total the annual fixed costs and divide by chargeable hours to get a charge-out rate/hour per vehicle category; include the mark-up, for-hire and reward operations. 

Variable costs: For a mixed fleet, estimate costs of each vehicle and decide on the charge-out rate per vehicle category. Look at cost per km (cpk) figures for fuel consumption (calculated or estimated), new tyres and retreaded tyres (estimated km), spares and repairs as a percentage of fuel cost (typically 30%) and extras (onboard equipment). This will give you a total for all variable costs and allow you to calculate the charge-out rate in rand/km.

Budgets, Quotations and Trip Costing

Having calculated a rate/hour and a rate/km for each category of vehicle in the fleet, it is possible to compile an annual budget, as well as rapid and reasonably accurate quotations and/or estimates of trip/load costs, either as “jobs” or as rates/tonne.

For example, a 650-km trip from Durban to Gauteng, costed at R26/km, can be added to an hourly rate of R360 over 12 hours, for a total of R21,220. For a 30-tonne load, this gives you a rate of R700/tonne.

There are two crucial points to note. Firstly, if it becomes necessary to “discount” the charge-out rates, it is essential that this is done only to fixed costs. Discounting the variable cost is commercial suicide. If too many jobs are discounted, the business will not be able to cover fixed costs and will fail.

Secondly, vehicle availability and usage are determining factors in transport operation costs. Availability reduces with vehicle age and utilisation depends on markets.

Management Accounting and Banking

From all of the foregoing information, it is obvious that the business of transport management requires rigid adherence to principles and the basic rule that the money in the business is owned by the business, not the owner or shareholders. These individuals are only entitled to their budgeted salaries and year-end profits (if any) after payment of all expenses.

Monthly management accounting for all expenditure and income must include a check on bank balances for reserves in the fixed- and variable-cost control accounts. It must also disclose any unplanned reductions. This is essential to ensure adequate control and to project impending problems to facilitate immediate action. Management of the invisible output called “transport” requires very diligent data monitoring and proactive management of standards.
