For a calculation question, include enough detail for us to repeat it. The checklist covers the inputs and comparison that help us investigate.

For a PDF or display problem, include your browser, device and the error message or a screenshot. Leave out client details the report does not need.

You can also suggest a calculator or a change to an existing tool. Describe the calculation you need and how you would use the result.
