Complaints & Copyright

If something on CD Calculators is wrong, unclear or feels unfair, we want to hear about it. Email legal@cdcalculators.net with the page URL, what you saw, and what you expected. Every message is read, and we aim to reply within a few business days.

Our formulas are published and unit-tested and our figures are cited, but mistakes do happen. If you think a number, statistic or citation is wrong, tell us the page and the claim — and point us to a better source if you have one.

Genuine errors are fixed promptly, with a dated note added wherever the change affected a number a reader may have relied on. We do not quietly edit outputs.

We respect intellectual property and expect the same in return. If you believe content on this site infringes your copyright, send a notice to legal@cdcalculators.net.

Please include: identification of the copyrighted work, the URL of the material you object to, your contact details, a statement that you hold a good-faith belief the use is not authorised, a statement under penalty of perjury that the information is accurate and that you are authorised to act, and your physical or electronic signature.

The formulas we publish describe standard financial math and are free to reference with attribution. Our written explanations, design and code are ours — please ask before republishing them in full.

We acknowledge complaints, investigate them, and respond with an outcome. If the resolution does not satisfy you, tell us and we will escalate it internally for a second review.
