Consumer Price Index (KPI) measures the average price development for all private domestic consumption, the prices the consumer actually pays. CPI is the usual measure for compensation and inflation calculations in Sweden. It is also the measure that Statistics Sweden uses.
Consumer price index with fixed interest (CPIF) is a measure of underlying inflation and aims to remove the effect of changing interest rates from the CPI. It is KPIF that the Riksbank wants down to 2 percent. This does not include mortgage interest.
The underlying inflation is called KPIF-XE. That does not include energy prices.
