How currencies work in these tools
Where a tool asks for money, you choose one of the listed currency codes and every amount is treated in that currency. Nothing is converted between currencies and no exchange rates are fetched. Tools that allow several currencies, such as the expense worksheet and the cost comparison, total each currency separately.
What these tools do not do
They calculate arithmetic from your inputs. They do not give legal, tax or investment advice, decide what a lease allows or check local rules. Downloads and printouts contain what you entered, so keep them private.
