Our calculators and guides answer money questions with figures you can check. This is how we make them.
Calculators
- Formulas in the open. Each calculator follows a published rule (an annuity formula, a federal tax scale, a bank's affordability test). The rule and its source are written next to the code, and every figure that changes by year (contribution rates, thresholds, maximum amounts) is a constant with its year and source.
- Tested. Every calculator is checked automatically against results worked out by hand before each release.
- Reviewed every year. Swiss figures (AHV, BVG, pillar 3a, federal tax, reference rate) are checked each January and when the authorities publish new ones.
Guides and comparisons
- Every figure links to its source, with the date. We prefer official sources (federal and cantonal offices) and say so when we use another.
- Comparisons state only facts we verified on the provider's own pages, with the date, and say fairly where the other product is better.
- Pages show when they were last updated.
Independence
Some pages may show an offer from a partner, always marked as an advertisement. Partners never change a calculator, a result or what we write. Results are indicative and are not financial, tax or legal advice.
