The indices behind price adjustment, on one screen

Price adjustment on a progress payment rests on the CPI for labour, on EPDK prices for fuel, and on TÜİK's domestic producer price indices for materials and machinery. We publish the latest figures here, with their monthly and annual changes.

The last 24 months. The final bar is the most recently published period.

Source and method

Where these numbers come from

TÜİK and CBRT EVDS
The series are published by TÜİK. Most are read from the Central Bank's EVDS system; the four-digit sub-indices are entered from TÜİK's tables. We do not produce the data; we pass it through.
Used in the Pn calculation
The price adjustment formula F = An × B × (Pn − 1) weights the indices by their coefficients. In the product this is calculated for you.
For information
This screen shows published values; an official calculation follows the periods and series your own contract specifies.
Leave the arithmetic to us

Stop working price adjustment out by hand

Indices arrive on their own, coefficients come from your contract, and the progress payment cover sheet builds itself.
