What to include

• Error reports: the calculator or article URL, the inputs you used, the result you got, and what you expected. We treat verified math errors as the highest priority.
• Feature requests: tell us what decision you were trying to make — the best calculator ideas come from real situations.
• Content questions: we are happy to clarify how a formula or assumption works.

What we cannot do

We cannot provide personal financial advice, recommend specific products, or review your individual situation. For decisions with real stakes, please consult a licensed financial adviser, accountant or tax professional in your jurisdiction.

We aim to reply within a few business days.
