Questions, corrections, and feedback all go to one inbox.

Replies typically go out within a few business days.

What to include

Data corrections — the page URL, the figure you believe is wrong, and if possible a link to the current primary source. These are handled first.
Formula questions — the tool name and the inputs you used, so the calculation can be reproduced.
Embedding — RungRate tools support an embed view for blogs and articles; questions about the snippet or attribution are welcome.
General feedback — ideas for tools or tables that would help you manage cash ladders.

Please note: RungRate cannot answer personal financial questions ("should I buy X?") — the site provides general information only, and email replies are not financial, tax, or investment advice.
