For most transport businesses, the fastest growth comes from keeping existing vehicles working more days rather than buying new ones. The Transport Business Growth Calculator shows how much extra revenue and gross profit you could earn by raising fleet utilisation, and how many extra vehicles that is equivalent to.

How the calculation works
- Current monthly revenue = vehicles x working days x current utilisation x revenue per vehicle per day.
- Revenue at target utilisation = the same formula with your target utilisation.
- Extra gross profit = the difference x your gross margin on extra work.
- Equivalent vehicles = extra revenue / revenue one vehicle earns at current utilisation.
How to raise utilisation
- Contact past customers when vehicles are free.
- Build relationships with brokers and shippers for backloads and short-notice work.
- Offer services that use idle capacity, where licences and insurance allow it.
- Plan maintenance for quiet days.
- Follow up every quote so fewer opportunities are lost.

Worked example (illustrative figures)
A fleet of 5 vehicles earns about R6,000 per vehicle on each working day, across 22 available days a month. At 60% utilisation the fleet earns 5 × R6,000 × 22 × 60% = R396,000 a month. Raising utilisation to 75% lifts revenue to R495,000: an extra R99,000 a month, which at a 30% margin on the extra work is about R29,700 of additional gross profit.
That gain comes from the trucks you already own. Buying a sixth vehicle at 60% utilisation would add similar revenue, but with new finance, insurance and driver costs on top.
Mistakes to avoid
- Counting calendar days instead of available working days after maintenance.
- Assuming every extra day earns the full daily rate: check your realistic rate for new work.
- Ignoring the margin on extra work, which is often lower than on contracted loads.
- Chasing utilisation with loads that do not cover their cost (check them in the Truck Profit Calculator).
The calculator shows amounts in rand, but the maths works in any currency: enter your figures in pounds, dollars or euros and read the results in the same currency.
Questions about fleet utilisation
What is fleet utilisation?
The share of available working days, or hours, that each vehicle is earning. A truck that works 15 of 22 available days has about 68% utilisation.
What utilisation should I aim for?
It depends on your operation, maintenance needs and market. Track your own figures weekly and set realistic step-by-step targets rather than a fixed industry number.
Is it better to improve utilisation or buy another vehicle?
Improving utilisation usually adds profit without new finance or insurance. Buy additional vehicles when existing ones are consistently busy and demand is proven.
