SSB's current table 14707 (2025=100) gives 3% for 2025; the 3.1% here is the rate on 2015=100, the base SSB names for its published 2017-2025 rates. Before 2017 the rates are computed from the 1998=100 annual averages (table 11449), as SSB published them.	4 of 5 checks Yes: Method and definitions published.

Official statistics from Statistics Norway, produced under the Statistics Act. Yes: Full count or representative sample. About 650 goods and services priced monthly from a sample of outlets, plus scanner data for groceries, pharmacies, fuel and more; weights from the national accounts. Yes: Raw data downloadable. Every annual and monthly value is downloadable from SSB's StatBank and PxWebApi. No: No known break or quality problem.

No source of these kinds: independent count.

Single source: nothing to check it against
SSB KPI, 1959: SSB: for 1914-1959 the all-item index is based on its Cost of Living Index (published since 1914); the CPI applies since 1959, and the CPI survey was established in 1960. source
SSB KPI, 1999: SSB modernised and improved the revision process and calculation methods, and changed the consumption classification to COICOP. source
SSB KPI, 2005: The food and non-alcoholic beverages sub-index became based exclusively on electronic scanner data. source
SSB KPI, 2011: National accounts data replaced the Household Budget Survey (used since 1960) as the weighting source; the price reference month changed from July to December. source
SSB KPI, 2016: Consumption classification extended to ECOICOP; classification by delivery sector revised. source
SSB KPI, 2020: Some price indices for services are based on estimated values as of April 2020 (SSB table note). source
SSB KPI, 2026: Reference year changed to 2025=100 from February 2026 (table 14709 replaces 08981). SSB: rates calculated on the new base may differ from those published before, mainly through rounding. source

Why the numbers differ (3)

The KPI is the price change households pay. CPI-ATE takes out energy products and the effect of changes in taxes and duties, so it moves less when electricity prices or VAT change; SSB calls it a measure of underlying price growth.
From 2004 to 2025 the CPI-ATE rose faster than the KPI in 8 of 22 years. Calculated from SSB tables 14707 and 08981 on this page. (source, retrieved 2026-10-27)
Rates differ slightly with the reference year: for 2025, SSB's 2015=100 index gives 3.1% and its 2025=100 table gives 3%. SSB says the deviations are mainly rounding. (source, retrieved 2026-10-27)

Common mistakes (3)

The annual average change is not the 12-month rate SSB headlines each month (for example, September over September); the two differ whenever inflation speeds up or slows down during the year.
An index level is not an inflation rate. To convert kroner between years, divide the two years' index values on the same base; never mix values from tables with different reference years. (source, retrieved 2026-10-27)
CPI-ATE is not a cheaper cost of living: it leaves out energy and tax changes that households do pay.

Context (2)

Sources considered and not used (3)

Norges Bank inflation series: Norges Bank's open data API lists exchange rates, interest rates and other financial series but no consumer price or underlying inflation series of its own, so there was none to add. (source, retrieved 2026-10-27)
SSB CPI-ATE before 2004: SSB's CPI-ATE index starts in 2003 (table 14707), so yearly changes start in 2004; no SSB table gives CPI-ATE back to 1979. (source, retrieved 2026-10-27)
Harmonized index of consumer prices for Norway (SSB): Built from the same SSB price collection as the KPI, so it would not be an independent line. (source, retrieved 2026-10-27)
