Economic meaning of vehicle fleet wear and tear
Any vehicle begins to lose its value from the moment it leaves the dealership. The process of gradually transferring the cost of a car to company costs as it wears out and wears out is called depreciation. Correct calculation of these indicators is critical for correct accounting and tax accounting, budget planning for fleet renewal and formation of the final cost of services (for example, in logistics or taxis).
The legislation offers several algorithms for writing off the cost of fixed assets. The choice of a specific approach depends on the intensity of equipment operation and the organization’s accounting policies. For vehicles, two main methods are most often used: classic linear and proportional to kilometers traveled.

Linear method: uniform distribution of costs
The linear method is the most common due to its mathematical simplicity. When using it, the cost of the car is written off in absolutely equal shares throughout the entire estimated period of operation, regardless of whether the car was idle in the garage or went on a daily trip.
The calculation formula is extremely logical:
- Annual rate: (Initial cost / Useful life in years).
- Monthly write-off:Annual rate / 12.
Practical example: A company purchased a corporate car for 2,400,000 rubles. According to the documents, its service life is set at 5 years (60 months).
We calculate the annual rate: 2,400,000 / 5 = 480,000 rubles per year.
We calculate the monthly write-off: 480,000 / 12 = 40,000 rubles. It is this amount that the accounting department will charge monthly to the company’s expenses until the cost is completely written off.
Method proportional to the amount of work (by mileage)
For commercial vehicles, trucks and special equipment, the linear method is often ineffective. A car can travel 150,000 kilometers in a year, and next year - only 20,000. In such cases, it is advisable to tie wear and tear to actual output - the kilometers traveled.
The calculation algorithm is based on planned indicators:
- Determination of the rate per 1 km:The initial cost of the car is divided by the expected total mileage over its entire service life.
- Calculation for the period: The resulting rate is multiplied by the actual mileage of the car for a specific month.
Practical example: A long-haul tractor was purchased for 8,000,000 rubles. The manufacturer claims a service life before major repairs of 1,000,000 km.
Depreciation rate: 8,000,000 / 1,000,000 = 8 rubles per kilometer.
If in March the tractor drove 12,000 km, the write-off amount will be: 12,000 × 8 = 96,000 rubles.
How to determine useful life (USL)
The key variable in any formula is service life. You cannot install it arbitrarily. In accounting, it is necessary to rely on the state Classification of fixed assets, which divides all property into depreciation groups.
| Cushioning group | Lifetime | Typical modes of transport |
|---|---|---|
| Third group | From 3 to 5 years inclusive | Small class cars, light trucks (up to 3.5 tons). |
| Fourth group | From 5 to 7 years inclusive | Minibuses, taxis, medium trucks. |
| Fifth group | From 7 to 10 years inclusive | Heavy long-haul tractors, large class buses. |
The organization has the right to choose the specific number of months within the permitted range independently and consolidate this choice in the accounting policy when placing the vehicle on the balance sheet.
Impact of residual value
It is important to understand the difference between accounting depreciation and actual market value. At the end of its useful life, the book value of the car becomes zero (it is fully self-depreciating). However, the car physically continues to exist and can be sold on the secondary market. Any amount received from the sale of a completely written-off vehicle will be recognized as net non-operating income of the company and subject to appropriate taxes.
