Cost index for passenger transport by bus describes the price trends for bus operating costs. The statistics are updated quarterly.
|Index level||Percentage change|
|4th quarter 2016||3rd quarter 2016 - 4th quarter 2016||4th quarter 2015 - 4th quarter 2016|
|Cost index for passenger transport by bus||121.6||6.9||6.9|
|Repair and maintenance costs||124.3||0.6||2.6|
The cost index for passenger transport by bus uses the following scheme to calculate interest related costs and depreciation costs:
- Depreciation over 10 years for buses with a residual value of 0 percent
- The interest cost is based on 10-year bonds with a premium of 1.79 per cent for Q1 2010-Q4 2015. Starting Q1 2016 this table is used to calculate the premium
- Inflation is adjusted by CPI-ATE
For Q4 2016 this resulted in a large increase in capital costs. A calculation based on the 3 month NIBOR rate would have resulted in a lower growth in capital costs for this quarter. In recent quarters, the 10-year bond yields have fluctuated more than 3 month NIBOR. When previous figures are small, changes are going to be large when measuring relative change.
