Mileage reimbursement vs company car: Cost analysis
Detailed analysis comparing actual costs between reimbursing employee mileage and providing company car.
A Decision That Deserves Real Numbers
Choosing between reimbursing employee mileage and handing them a company car is one of the most consequential financial decisions a growing business makes about its fleet. It looks simple on the surface, but the right answer depends on how much people actually drive, how the tax treatment shakes out, and how much risk the company is willing to carry. Guessing is expensive in both directions.
The honest way to make this call is to run the numbers for your own situation. The illustrative figures below show the structure of the comparison; plug in your local costs and usage to get an answer you can defend to finance and to leadership.
What a Company Car Really Costs Each Year
A company car carries far more than a sticker price. Take an R$ 80,000 vehicle: in year one alone, depreciation at roughly 20 percent is about R$ 16,000. On top of that sit insurance near R$ 4,500, vehicle tax (IPVA) around R$ 2,400, and maintenance close to R$ 3,000. Fuel for 20,000 km, at R$ 6 per liter and 12 km per liter, adds another R$ 10,000.
Add it up and a single vehicle runs roughly R$ 35,900 a year. That figure is fixed whether the car is driven hard or barely at all, which is the key weakness of the model for low-utilization roles.
What Reimbursement Costs by Comparison
Reimbursement scales with actual driving. At R$ 1.50 per km over 20,000 km, the direct cost is R$ 30,000 a year. Add administrative overhead, the app and the HR time to manage claims, of roughly R$ 2,400, and the total lands near R$ 32,400 per employee.
At first glance reimbursement looks about R$ 3,500 cheaper per year. But a single-year, single-driver snapshot hides the variables that actually decide the question, so it is worth looking past the headline number.
Flexibility and Scale Change the Math
Flexibility favors reimbursement when utilization is uneven: the company pays only for kilometers actually driven, while a company car keeps charging even on light months. For a single employee who drives moderately, reimbursement is almost always cheaper.
Scale flips the logic. Once you have five or more people driving heavily, a fleet can unlock volume discounts on purchase, insurance, and maintenance through corporate contracts that an individual reimbursement program cannot match. The crossover point is where per-vehicle fleet economics finally beat per-kilometer payouts.
The Tax and Compliance Angle
Tax treatment can move the decision meaningfully. A company car used exclusively for work is generally fully deductible, while reimbursement is deductible when it is well documented. The catch is personal use: when an employee uses the company car for private trips, that benefit typically becomes taxable.
In the US, the IRS sets the standard mileage rate[^irs-2025] that anchors reimbursement, and it publishes specific rules on the personal use of employer-provided vehicles[^irs-personal-use]. Whichever path you choose, clean records are what keep the deduction intact, which is precisely where consistent tracking earns its keep.
Who Carries the Risk
Risk allocation is easy to overlook and expensive to get wrong. With a company car, the business owns the asset and absorbs the exposure to accidents, theft, and depreciation surprises. With reimbursement, the employee owns the vehicle and carries that risk, while the company simply pays for the kilometers driven.
For some organizations, shifting that liability off the books is worth a premium on its own. For others, the control and brand consistency of a managed fleet justifies holding the risk. The right answer depends on appetite, not just arithmetic.
A Practical Rule of Thumb
Distilled to bands of annual mileage, a useful starting point emerges. Under about 15,000 km per year per person, reimbursement is usually the better deal. Above roughly 25,000 km per year, a company car tends to win on total cost. Between 15,000 and 25,000 km, the decision is genuinely case by case and should turn on tax position, risk tolerance, and team size.
The thread running through all of it is data. Before committing either way, track each employee's actual kilometers with Quilometragem so the decision rests on real driving rather than estimates. Export the figures via CSV to your accounting stack or to Clara, and revisit the analysis annually as usage and costs shift.
