Contact & corrections

Found a formula that looks wrong, or a bug in a calculator? Formula corrections are launch-blocking issues and get priority review — see our methodology page for how formulas are tested.

Placeholder — wire up a real contact form or support email at deploy time (RACI owner: Product Lead, per blueprint §15).

What to include when reporting a calculation issue

• Which calculator, and the exact inputs you used.
• The result you got, and what you expected.
• Any reference source you're comparing against, if applicable.
