Dollar utilisation is the rental revenue a machine generates over a measurement period, expressed as a percentage of what it would cost to replace that machine today. Where time utilisation tells you how busy a piece of kit is, dollar utilisation tells you how hard it is working in pounds per pound of capital tied up.
Why dollar utilisation matters
Two excavators can both sit at 70% time utilisation and one of them can still be quietly losing the fleet money — because it is being rented at the wrong day rate, with too many free-hire days, or against a replacement cost that has crept up faster than your pricing.
Dollar utilisation is the figure that drags those quiet problems into daylight. It is also the number a sensible finance director looks at before signing off the next round of capex, because it is the only utilisation metric expressed in money.
How to calculate dollar utilisation
The formula is straightforward; the inputs are where operators trip up.
- Annualised rental revenue = trailing-12-month rental income from the asset, excluding waiver, fuel and delivery
- Equipment cost = current replacement cost (recommended) or original purchase price
- Worked example: a £45,000 telehandler that earned £18,000 of rental revenue over the last 12 months has a dollar utilisation of 40%.
- UK benchmarks: 35–60% is healthy across most plant-hire categories. Below 25% is a sell-or-redeploy candidate.
- Use current replacement cost rather than the original invoice for anything older than three years — inflation in plant prices has been brutal and original cost will flatter the number.
Common mistakes
The four traps that account for most of the bad answers we hear when we ask operators about dollar utilisation.
- Using the original purchase price for a five-year-old machine. Replacement cost gives a cleaner signal.
- Including damage waivers, fuel surcharges and delivery in the revenue figure — strip them out, you are measuring the machine, not the whole invoice.
- Mistaking high dollar utilisation for a healthy business. If time utilisation is 95% you are turning work away and could probably raise rates.
- Tracking only the fleet-wide number. The interesting figure is dollar utilisation per category, per depot, per quarter.
How MovoGo handles dollar utilisation
MovoGo calculates dollar utilisation on every asset against either original or replacement cost — the choice is yours — and surfaces the worst-performing 10% so you can decide whether to re-price, redeploy, or off-fleet.
The terms most often confused with, or directly tied to, dollar utilisation.
- Rental utilisation — The percentage of time, revenue or operating hours a rental machine is actually earning, measured against everything it could have earned.
- Hire desk — The team and system that take hire enquiries, raise contracts, organise delivery and handle off-hire — the operational nerve centre of any plant-hire business.
- Damage waiver — A daily or weekly fee that caps the customer's liability for accidental damage, with the rental company carrying the cost above the cap.
- Cycle billing — Invoicing a long-running hire on a regular weekly, fortnightly or monthly schedule, rather than waiting until off-hire.
