Include the page address, the inputs you used, the result you got and the result you expected, and the source you are relying on. Reports about a figure or a formula are prioritised over everything else. What happens next is described on the corrections page.
Questions about how a tool works, requests for a calculator that does not exist yet, and press enquiries all go to the same address. We do not provide personalised financial advice by email, and requests for it will not be answered.
