Helpful feedback to send
Useful notes include calculator mistakes, missing conversion types, unclear wording, broken links, mobile display problems, or suggestions for the next calculator page.
For calculator corrections, the most helpful report includes the browser or device you used, the exact calculator page, the values entered into each field, and a short explanation of why the result seems wrong. For new calculator ideas, include the everyday question the tool should answer and any formula or example you already use.
Common requests that fit this site include payment estimates, savings comparisons, unit conversions, percentage calculations, trip cost estimates, measurement conversions, and other tools that can be explained clearly on a single focused page.
Response expectations
Messages are reviewed as time allows. Calculator correction reports and broken-link reports are the highest priority because they directly affect the usefulness of the site. General business, advertising, and partnership questions may take longer.
Please do not send private financial information, account numbers, Social Security numbers, medical information, passwords, or other sensitive personal details. The calculators are intended for general planning and do not require private account access.
