What the calculators include, and what they leave out
Every cost the default calculation does not account for, how rounding is handled, and why currency is never converted.
Last reviewed against the product on .
The calculators on this site are deliberately small, and each one states what it is not accounting for. This page collects those limits in one place so you can see them together.
They calculate, they do not advise
Every figure is arithmetic over numbers you supplied. None of it is a recommendation, a forecast, or a claim about what your business should do.

Rounding
Money is rounded to two decimal places at the point it is stored. Intermediate arithmetic is not rounded, so a total is not the sum of the rounded parts and may differ from a hand calculation by a penny. That is the correct behaviour and the alternative is worse: rounding at every step accumulates error in one direction.
Currency
Never converted, anywhere. Two figures in different currencies are not added, compared or totalled. If you buy in more than one currency, each stands on its own.
