Who writes the content
Guides and calculator explanations are written and maintained by the Capital Calculators editorial team. We write for people making real decisions about borrowing, saving, investing and running a business, so the aim of every page is a clear answer you can check for yourself.
Our standards
- Accuracy first. Every figure in a worked example is calculated, not estimated, and is reproduced by a calculator on this site. See how our calculators work.
- Plain language. We define each term the first time it appears and keep a glossary for reference.
- Balance. Where a choice involves a trade-off, we set out both sides and say who each option tends to suit.
- Evergreen. We avoid quoting rates, limits and rules that change from year to year or differ by country. Where a rule of thumb is used, we say that it is one.
- Sources. Guides list official sources for further reading, such as regulators and government agencies.
Independence
Content is not written to promote any lender, broker, fund or product. We do not accept payment to change a calculation, a ranking or a recommendation. If the site ever carries advertising or affiliate links, they will be clearly labelled and will not influence the content.
Review and updates
Each guide and calculator shows the date it was last reviewed. Pages are rechecked when a formula changes, when a reader reports a problem and on a regular schedule.
Corrections
We fix confirmed errors promptly. To report one, email hello@capitalcalculators.com.
Not advice
Everything here is general education. It does not take your circumstances into account and is not financial, tax or legal advice. See our terms.
