Plant hire profit margins explained
Gross and net margin in plant hire explained: how to calculate margin per machine, what drives it, where it leaks, and the levers that improve it.
Key takeaways
- Gross margin is hire income minus the direct costs of the machines; net margin is what's left after overheads.
- Measure margin per machine: fleet averages hide the losers.
- Utilisation, rate discipline and delivery pricing drive margin more than anything else.
- Margin leaks through free delivery, unbilled extras, downtime and bad debt.
Gross and net margin
| Measure | Formula | Tells you |
|---|---|---|
| Gross margin | (Hire income − direct machine costs) ÷ hire income | Whether the fleet earns |
| Net margin | Net profit ÷ total revenue | Whether the business earns after overheads |
Direct machine costs are finance or depreciation, servicing and repairs, insurance and tracking for the machine. Overheads are the yard, office, vehicles, staff not tied to one machine, marketing and software.
Margin per machine
Work it out monthly from your booking system and accounts. Rank machines by margin and look hard at the bottom three. See utilisation and break-even.
What drives margin
| Driver | Effect |
|---|---|
| Utilisation | Fixed costs spread over more hire weeks |
| Rate discipline | Fewer discounts and free extras |
| Machine cost | Buying well, used where sensible |
| Maintenance | Less downtime and fewer big repairs |
| Attachments | High-margin add-ons |
| Delivery pricing | Trips that pay for themselves |
Where margin leaks
- Free or under-priced delivery.
- Fuel, cleaning and damage not charged.
