Inflation adjustment of amounts
Convert amounts between verified CPI years; the default target is the latest complete year 2025, not observed 2026 prices.
- Data → operation → output
- CPI 2015: 313.35; 2022: 371.91; 2025: 417.98 (1980=100). Amount and explicit price-basis year. → Amount × CPI(target year)/CPI(base year); only 2015, 2022 and 2025. Missing indices or non-finite amounts are rejected. → Belopp med prisomräkning, bl.a. kostnadsklockan
- Primary sources
- Assumptions
- The CPI basket is used as a comparison index. No CPIF forecast replaces an annual CPI average.
- Observed vs modelled
- Indices are confirmed Statistics Sweden annual averages; amount conversion is an own derivation. The 2026 annual average is unavailable and is not used.
- Uncertainty
- CPI measures a household basket, not the same cost development for every amount.
- Limitations
- An amount without an evidenced price basis must not be CPI-adjusted using an assumed base year.
- Scope of validity
- Sweden; SEK between price years 2015, 2022 and 2025.
- Reproducibility
- Annual averages from the Statistics Sweden original and conversion signs/zero/ratio are tested.
