Contact

If a result looks wrong, or there is a calculator you wish existed, tell us. This is a one-person site, so replies are not immediate — but every message gets read.

How to reach us

Email hello@tooldeb.com — the only channel. There is no phone line, no walk-in desk, and no chat widget.

Reporting a wrong number

Three things make it far faster to reproduce. First, which tool — a link to the page is ideal. Second, the values you entered. Third, what you believe the answer should be, and why.

If there is a statute, an official notice, or a standards document behind your expected value, include it. Fixes are made by reading the same source text, so a citation changes how quickly it gets corrected.

Suggesting a tool

One line on what you calculate and why you do it often is enough. Not every suggestion gets built — tools are added in the order that real search demand shows up in the data.

What we do not answer

No individual tax, legal, or medical advice. This site computes published formulas and statutory text; it is not qualified to judge one person's situation. If that is what you need, a professional in the field and the relevant authority will get you there faster.

Advertising placements, partnerships, backlink exchanges, and sponsored-post offers do not get a reply.
