Company truck or your own: which leaves you better off

Buying6 min read

A company-provided vehicle removes purchase cost, maintenance, insurance and depreciation risk from you entirely, which usually wins on pure economics. Providing your own makes sense when the reimbursement genuinely covers total running cost, when you need the vehicle outside work, or when owning it is what lets you take side work. Compare against full cost per mile, not fuel. Confirm tax treatment with your own accountant.

Start by counting what the employer actually absorbs

When a company provides the vehicle, it carries purchase or lease cost, insurance, registration, maintenance, tyres, and — often overlooked — depreciation. That last one is usually the largest single cost of operating a vehicle and the one people ignore because no invoice ever arrives for it.

It also absorbs risk. A transmission failure, a major body repair, a vehicle off the road for three weeks: none of that becomes your problem, and none of it lands on you at a moment you cannot afford it.

Against that, you generally accept restrictions. Personal use may be limited or prohibited, the vehicle may carry tracking, and the specification is chosen for the company rather than for you. If personal use is permitted, it may be a taxable benefit — worth establishing early rather than discovering at year end.

What running your own actually costs

The mistake almost everyone makes is comparing reimbursement against fuel. Fuel is the visible cost, not the largest one. The real figure includes depreciation, insurance at commercial rates, maintenance, tyres, registration and the repair fund you should be building whether or not you actually are.

Work out your own cost per mile before comparing anything. Total everything you spent on the vehicle over a year, divide by miles driven, and use that number. For most work vehicles it lands considerably higher than people expect, and it is the only figure that makes the comparison honest.

Insurance deserves particular attention. A vehicle used for business generally needs commercial cover, and a personal policy may decline a claim on business-use grounds. If you are running your own truck for work on a personal policy, the comparison you think you are making is not the one you are actually in.

Then there is the depreciation you are personally absorbing. Hard miles, heavy loads and a bed full of tools age a vehicle faster than commuting does, and that cost is real even though it only becomes visible on the day you sell.

When providing your own genuinely wins

When the reimbursement rate comfortably exceeds your true cost per mile, and the mileage is high enough for the margin to matter. Run the arithmetic on your actual annual mileage rather than on a rate in isolation — a generous-looking rate over low mileage is worth very little.

When you need the vehicle outside work anyway. If you would own a truck regardless, the marginal cost of using it for work is much lower than the full cost, and the comparison shifts substantially in your favour.

When ownership is what enables side work. A contractor who takes independent jobs at weekends needs a vehicle nobody else controls, and that freedom can be worth more than the cost difference.

And when the company vehicle would be wrong for the job. If what is offered cannot do the work properly, the economics matter less than being able to do your work at all.

When taking the company vehicle is clearly better

When your credit or cash position makes buying difficult. A company vehicle lets you do the work now rather than waiting until you can fund one, and that timing can matter more than the long-run economics.

When the work is hard on equipment. If the job involves heavy loads, rough sites or high mileage, letting the employer absorb the wear is straightforwardly the better position to be in.

When the vehicle needs an expensive upfit. Specialist bodies, cranes, compressors and similar equipment cost real money and are difficult to recover on resale if your circumstances change.

And when the reimbursement is thin. Some rates are set at levels that quietly transfer cost onto the person driving, and no amount of independence compensates for losing money on every mile.

Questions worth asking before deciding

If taking a company vehicle: is personal use permitted, and how is it treated for tax? Who pays for tyres and routine servicing? What happens if it is off the road — is there a replacement, and are you paid meanwhile? Is there tracking, and does it operate outside working hours?

If providing your own: exactly what does the reimbursement cover, and how is it calculated? Does it change with fuel prices? Who pays if the vehicle is damaged on a job? Does the company require particular insurance, and will it pay the difference from a personal policy?

Get the answers in writing. These arrangements are frequently agreed verbally in a good moment and then remembered differently a year later, almost always at the point where real money turns on which version was correct. A short written summary costs nothing and settles it permanently.

The short version

  • Compare reimbursement against full cost per mile, never against fuel alone.
  • Depreciation is usually the largest cost of running a vehicle and the easiest to overlook.
  • Business use generally requires commercial insurance; a personal policy may decline the claim.
  • Providing your own wins when you would own the vehicle anyway or it enables side work.
  • Take the company vehicle when the work is hard on equipment or needs an expensive upfit.
  • Get the terms in writing — these arrangements are remembered differently when money is at stake.

Questions people ask

How do I work out my real cost per mile?
Total everything the vehicle cost over a year — payments or depreciation, insurance, registration, maintenance, tyres, fuel and repairs — then divide by miles driven. Use that figure, not fuel, for every comparison you make.
Is a mileage reimbursement usually enough?
It depends entirely on the rate and your mileage. Some rates comfortably exceed real cost; others quietly shift expense onto the driver. The only way to know is to compare against your own cost per mile rather than against a published figure.
Do I need commercial insurance for my own truck used at work?
Generally yes. Personal policies commonly exclude or restrict business use, and that exclusion tends to surface after an incident. Ask your broker directly, because the answer changes the economics of the whole decision.
Is personal use of a company vehicle taxable?
It commonly is treated as a benefit, but the treatment depends on the arrangement. Establish it with your employer and your accountant before accepting rather than finding out when the year-end figures arrive.
What if the company truck is not right for the job?
Raise it as a work problem rather than a preference, with specifics — what the vehicle cannot carry, reach or tow. A concrete operational limitation is a far stronger case than a general complaint about the vehicle.
Does using my own truck for work hurt its resale value?
Yes. Work use means hard miles, heavy loads and a bed that takes punishment, and all of it shows at sale. That accelerated depreciation is a real cost you are carrying, even though it only becomes visible on the day you sell.
Can I negotiate which option I take?
Often, particularly if you can show the arithmetic. An employer presented with a clear cost comparison is in a different conversation from one hearing a preference, and the numbers sometimes favour the company too.
