Journeys & mileage

Trip costs, driving time, and what to claim for business miles.

A journey has two costs and people usually only price one. Fuel is the obvious one. The rest — tyres, servicing, depreciation, the share of insurance attributable to the miles — is typically two to three times the fuel, which is why reimbursement rates are so much higher than fuel alone would justify.

Driving time is the other thing worth working out honestly. Average speed over a long journey is always well below the limit once stops, towns and traffic are counted, and planning at the limit is how arrival times slip.
