Try answering this simple question: how many rupiah does your company actually spend every time one company vehicle travels one kilometer? If you are not sure of the answer, you are not alone. Many companies only record fuel expenses and workshop bills, then treat those figures as their company vehicle operating costs. In fact, the largest share often comes from items that never appear on daily receipts, such as vehicle depreciation, driver salaries, and the time vehicles sit idle during repairs.
This misconception has real consequences. Transportation budgets miss the mark, the pricing of services that depend on deliveries or team mobility becomes less accurate, and important decisions such as adding new units are made without solid data. In the simulation discussed in this article, fuel turns out to be only about 23% of a vehicle's total monthly cost, while the rest is spread across other cost items.
That is why understanding how to calculate fleet operating costs is not just a matter for the finance team. Operations managers, procurement teams, and company leaders need to see the same picture so that every vehicle truly adds value to the business. This article covers the full set of cost components, the vehicle cost per kilometer formula, sample calculations for small and medium fleets, commonly overlooked hidden costs, and the considerations between buying assets and leasing a fleet.
Company vehicle operating costs are all expenses incurred so that a vehicle can be used to support business activities, from the moment the vehicle is acquired until it is disposed of. This approach is often called total cost of ownership (TCO), which looks at the cost of a vehicle as a whole rather than per transaction.
In general, these costs fall into two main groups. The first is fixed costs, which still arise even when the vehicle is rarely used, such as depreciation, taxes, insurance, and driver salaries. The second is variable costs, which rise and fall with the distance traveled, such as fuel, tolls, servicing, and tires. This distinction matters because it determines the most effective cost-saving strategy.
Before getting to the formula, you need to map out every operating cost component of the cars your company owns. Here is the breakdown.
Depreciation is the decline in a vehicle's value over time and with use. Although it is not cash leaving the business every month, this item is often one of the largest costs. For tax purposes in Indonesia, vehicles generally fall under Group 2 non-building tangible assets with a useful life of 8 years. The rate is 12.5% per year under the straight-line method, or 25% per year under the declining balance method, as set out in Minister of Finance Regulation (PMK) No. 72 of 2023. For internal calculations, some companies also use an estimated resale value to make the figures more realistic.
Fuel is the easiest variable cost to monitor. It is determined by the vehicle's fuel consumption, distance traveled, road conditions, and driving style. Habits such as sudden acceleration or leaving the engine running while waiting can drive up fuel consumption without anyone noticing.
For vehicles that frequently serve intercity routes or travel between industrial estates, toll costs can be significant. Add daily parking fees too, especially for vehicles that take guests or sales teams into the city center.
Routine servicing includes replacing oil, filters, and brake fluid, checking the suspension, and other components according to the manufacturer's schedule. Disciplined maintenance does add to routine spending, but it is far cheaper than major repairs caused by neglected damage.
Tires are consumables whose lifespan depends on distance traveled, load, and road conditions. The most practical approach is to take the price of one set of tires and divide it by its estimated lifespan in kilometers.
Every year, vehicles must pay Motor Vehicle Tax (PKB) along with other components listed on the vehicle registration certificate (STNK). Since January 5, 2025, under Law No. 1 of 2022 on Financial Relations between the Central Government and Regional Governments (HKPD), a PKB surcharge (opsen PKB) of 66% of the base PKB is collected by regencies and cities. However, the maximum base PKB rate has also been lowered, so the total tax burden is not much different from before. Also remember the five-yearly license plate and STNK renewal fees.
Insurance protects the company from major losses caused by accidents, damage, or theft. Premiums are usually calculated as a percentage of the vehicle's price and depend on the type of coverage chosen, such as all risk or total loss only.
If the vehicle is operated by a driver, this component covers base salary, overtime pay, meal allowances, the religious holiday allowance (THR), BPJS social security contributions, and training costs. In many cases, driver salaries are the single largest cost item in vehicle operations.
Once all components are collected, the next step is to convert them into a unit that is easy to compare: vehicle cost per kilometer. The basic formula is:
Cost per km = (Total fixed costs + Total variable costs) ÷ Total distance traveled
For sharper analysis, you can split it into two parts:
This split helps you spot an important pattern. Fixed cost per km falls when the vehicle is used more productively, while variable cost per km stays relatively stable and can only be reduced through route efficiency, maintenance, and driving habits.
The figures below are an illustrative simulation. Fuel prices, insurance premiums, and tax rates may vary by region and over time, so adjust them to your company's data.
Assumptions per unit: vehicle price of Rp300 million, 3,000 km traveled per month, fuel consumption of 1 liter per 10 km, and a fuel price of Rp13,000 per liter.
Monthly cost breakdown per unit:
The total cost per unit is Rp16,850,000 per month. With 3,000 km traveled, the cost per kilometer is around Rp5,617. Of this, fixed costs are around Rp3,717 per km and variable costs around Rp1,900 per km. For 5 units, the total fleet operating cost reaches Rp84,250,000 per month, or around Rp1.01 billion per year.
This simulation shows that fuel accounts for only about 23% of total costs, while driver salaries reach about 41%.
Suppose a company has 15 MPV units with the same assumptions as above, plus 10 minibuses for employee shuttles.
Assumptions per minibus: price of Rp600 million, 2,500 km traveled per month, and fuel consumption of 1 liter per 8 km.
The total per minibus is Rp22,812,500 per month, or around Rp9,125 per km.
Combined, the 15 MPVs cost Rp252,750,000 and the 10 minibuses cost Rp228,125,000. The total cost of this medium fleet reaches Rp480,875,000 per month, or around Rp5.77 billion per year, excluding the hidden costs discussed next.
This is the part that often pushes fleet budgets off target.
When a vehicle is in the workshop, its fixed costs keep running, but it delivers no value. If operations cannot stop, the company has to rent a replacement vehicle at short notice, usually at a higher price.
The staff time spent on STNK renewals, insurance claims, service scheduling, and expense reporting is a real cost. On top of that, there is the need for a vehicle tracking system.
When the main driver is on leave or sick, the company needs a replacement driver. Without planning, this item often shows up as overtime or unexpected costs.
Damage from minor accidents, components wearing out faster than scheduled, or the deductible on insurance claims can eat into the budget.
The hundreds of millions of rupiah tied up in vehicles could otherwise be used for business expansion. In addition, used vehicle resale prices are often lower than expected, especially when the maintenance history is incomplete.
Buying vehicles gives full control over the assets and suits companies with substantial capital and an internal team ready to manage a fleet. However, the company must bear depreciation, maintenance, taxes, insurance, downtime risk, and the resale process on its own.
On the other hand, long-term fleet leasing turns a large upfront capital expense into a more predictable monthly cost. Maintenance, insurance, and replacement vehicles are generally included in the lease package, so the internal team can focus more on the core business. From an accounting perspective, lease costs are recorded as operating expenses, but their tax treatment should be discussed with the company's tax consultant.
The most objective way to choose is to compare the cost per km of ownership, including hidden costs, with the cost per km of a lease offer for the same distance traveled.
The following steps can help control costs without disrupting operations:
There is no fixed figure, as it depends on the type of vehicle, operating region, and level of use. What matters most is having an internal benchmark and comparing it over time.
Yes. A fully paid vehicle still loses value every year. Ignoring depreciation makes operating costs look lower than they really are.
Ideally every three months, or whenever there is a major change such as a fuel price increase, a toll rate adjustment, or the addition of new units.
Calculating company vehicle operating costs comprehensively helps businesses make decisions based on data rather than estimates. Map out every cost component, from depreciation, fuel, tolls, servicing, and tires to taxes, insurance, and driver salaries. Then use the cost per kilometer formula to compare the efficiency of each unit, and do not forget hidden costs such as downtime, administration, and the cost of capital. With clear figures, a company can objectively assess whether it is more profitable to buy its own assets or switch to fleet leasing.
