Methodology
Räkna.nu tries to be clear that every calculator is a model. The model can be simple or more advanced depending on the topic, but it always relies on assumptions that should be visible to the user.
How calculations are built
Each calculator defines its inputs, default values, and calculation logic in code. For Swedish economic topics, the site primarily relies on public rules, percentages, and tax tables. When exact real-world outcomes may vary, the result is presented as an estimate rather than a promise.
How content and calculators work together
The goal is not only to show a result but also to provide context. That is why many pages include questions and answers, explanatory text, related tools, and sometimes deeper content. The editorial layer should help users understand when a calculator is useful and when more verification is needed.
Limitations
Taxes, public benefits, fees, and local rules can change. Individual circumstances can also make real outcomes differ from a general model. For decisions with significant financial consequences, you should therefore verify the current rules with the relevant authority or an adviser.
