"Cost per mile" sounds simple. The version most businesses calculate is wildly understated. The version that matters in long‑term contracts includes everything — including the costs that don't appear on the obvious invoices.
What a real cost‑per‑mile calculation includes
- Vehicle finance or capital cost
- Depreciation
- Insurance, VED, MOT
- Routine servicing and tyres
- Major repairs and parts
- Compliance (DVS permits, AdBlue, calibration)
- Downtime cost during repairs
- Driver pay during VOR
- Admin and supplier management overhead
When you load all of those in, owned vehicles' cost per mile is usually higher than businesses expect.
Why CoreHire often comes out ahead
CoreHire packages the vehicle, maintenance, MOT, breakdown cover and replacement into a fixed monthly rate. Once you divide that rate by realistic monthly mileage, the cost per mile is:
- Lower in variance
- Easier to forecast
- Easier to attribute to customers, projects or routes
Where to be honest with the maths
- Don't compare the lease rate to your "out of pocket" maintenance bill — compare it to the real total cost
- Include the cost of the time your team spends managing it
- Include the financial cost of downtime, not just the repair invoice
Why we'll happily run the numbers with you
We'll build a transparent comparison using your real fleet, real mileage, and real maintenance history.
