nykyrahassa

Nykyrahassa is a Finnish term used to describe monetary values expressed in present-day purchasing power, i.e., adjusted for inflation. It is not a separate currency, but a method for making long-term comparisons meaningful by removing the distortions caused by changing price levels. Economists typically convert historical amounts to nykyrahassa using price indices such as the consumer price index (CPI). The general formula is value in nykyrahassa = historical value × (CPI current / CPI base); the choice of index and base year influences the result.

Common uses include reporting historical prices, wages, rents, or government expenditures in current money; comparing standards of living across decades; and presenting long-run economic trends in journalism and research. The concept helps to maintain comparability when discussing changes over time.

Limitations include dependence on the chosen index and basket of goods, and the fact that inflation adjustment does not capture changes in quality, product mix, technology, or services. Additionally, inflation-adjusted figures may still not reflect all real-world differences in purchasing power.

In Finnish statistics and economics literature, nykyrahassa is frequently used to express series in a consistent, current-value context. Tilastokeskus (Statistics Finland) and other statistical agencies publish historical time series with adjustments to nykyrahassa to aid interpretation and comparisons.
