Disclaimer
Our tools are built carefully and tested, but a calculator can only be as good as its inputs and assumptions.
General information, not advice
Results and explanations on Calcuno Now are for general information and education. They are not financial, tax, legal, medical, academic or engineering advice. For decisions in those areas, confirm figures with a qualified professional or with the organization that sets the rules.
Assumptions matter
Many everyday calculations depend on conventions that differ between countries, institutions and contracts. Examples include how a school rounds or weights grades, which days count as working days, when someone born on 29 February reaches a legal age, how an employer rounds working time, and whether a recipe uses US, imperial or metric cups. Each tool states the convention it uses. If yours is different, the result may be different too.
Rounding
Results are displayed rounded for readability, as explained on each page and on the methods and sources page. Rounded values can differ slightly from an exact figure, a receipt, or an official calculation that rounds at different steps.
Money
Money tools work with any currency but do not know local tax rules, service charges, currency rounding or cash-rounding rules. Prices, taxes and tips shown are estimates.
Errors
If you find a mistake, please report it. We correct confirmed errors as a priority. See also our terms of use.
