Report a calculation issue
Before the public launch, we will publish a monitored contact email on this page. For a useful calculation report, include the calculator page, input values, the result you saw and the result you expected. Do not include account numbers, passwords or other sensitive information.
What we can help with
We welcome reproducible reports of calculation errors, unclear assumptions, broken links and accessibility issues. We cannot provide individual investment, banking, tax or legal advice.
Privacy requests
The public privacy contact will also appear here before launch. The Privacy Policy identifies Francisco Almeida as the site owner and will state the contact route and how requests are handled.
