Methodology
Our methodology explains calculator models and how you can check a result.
Three types of calculation model
Rule-based calculators use Swedish rules or tables and depend on the correct year and personal conditions. Projections such as saving assume a duration, deposits and returns. Mathematical tools calculate percentages or convert units; correct inputs and units are essential.
Defaults and your own information
A result using default values is an example, not a personal assessment. Check the income period, year, amounts and units, then replace defaults with relevant information. Change one assumption at a time to understand its effect.
How to check a simple result
As a check, calculate 1000 × 10% = 100. Compare inputs, formula and result, and confirm whether amounts are monthly or annual and before or after tax. For rule-based calculations, also compare the official source for the applicable year.
Limitations
A correct formula can still give incomplete guidance if inputs or assumptions are wrong. Projections do not guarantee returns, benefit calculators do not decide eligibility and health measures do not replace individual assessment. Verify important personal conditions before acting.
Review dates, rule years and corrections
A review date tells you when content was checked; a rule year or effective date tells you which rules apply. These are different details. Rule changes require another review of the calculation and explanation. Report discrepancies through Contact with the page, language and source.
Editorial and technical responsibility
The editorial team at Räkna.nu is responsible for technical and editorial review. For rule-based calculators, that review covers calculation logic against the cited primary sources, tests of displayed examples, visible assumptions and limitations, and the review date.
