Calculation method and data sources
The vehicle's market value and depreciation are determined under the Constitutional Court's decision dated 29/12/2022, numbered 2021/82 E., 2022/167 S., in accordance with standards generally accepted in the market and on the basis of current market data.
Data sources
- Companies using dealer and inventory management software
- Auction platforms (data on completed purchases and sales from B2B and B2C platforms)
- Fleet leasing and online sales platforms
- Digital platforms of authorized dealers
- Listing sites
Methodology
The infrastructure used in vehicle depreciation calculations is based on advanced analysis systems supported by AI, machine learning and big data technologies. These systems scan and analyze millions of second-hand vehicle listings offered for sale on the online market every day.
Data Coverage
For Türkiye, a daily average of 550.000 vehicle listings belonging to more than 40.000 corporate sellers from 32 different online sources are reviewed; approximately %98 of the market is thus continuously monitored.
Thanks to this strong data infrastructure, price changes, supply-demand balances and trends in the second-hand vehicle market are tracked instantly, and the most current and reliable information is obtained. Corporate B2B sales data are also taken into account in the calculations, so the most accurate vehicle depreciation calculation is made by considering price dynamics on both the supply and demand sides.

Damage assessment
Damage identified in the post-accident appraisal:
| Part | Condition | Paint |
|---|---|---|
| Front panel (sheet metal) | Repair (High) | Full |
Damage amount: 36.993,60 TL · Number of damages: 0 (not a rental) · Rental?: No
Critical Finding
Front panel (sheet metal) repair and full paint directly affect the vehicle's value. However, no damage was identified in load-bearing parts such as the chassis, pillars or roof.
Current valuation calculation
In the current valuation, the loss of value is the difference between the vehicle's undamaged and damaged second-hand market values. Both values are valuation results obtained from market data; they are not derived from a coefficient formula:
Loss of Value = Undamaged Second-Hand Market Value − Damaged Second-Hand Market Value
Depreciation calculation — with sample data
Comparison with the annulled formula
The formula annulled by the Constitutional Court consists of the following steps. Intermediate values are used unrounded and the result is rounded to a whole number:
1. HK = (Repair Coefficient + Paint Coefficient)
2. T = ((Damage Amount / Market Value) × 100) × 0,10
3. H = (HK + T) / 100
4. G = 1 + (G1 + G2 + G3)
5. DK = Market Value × R × KS × H × G
Result and comparison
The report presents three different results:
As can be seen, the two methods produce different results for the same vehicle. The current valuation (after Constitutional Court decision 2022/167) better reflects the true market value because it is based on current market data. The average estimated loss of value is the average of the two methods.
