What makes a useful note

A correction is fastest when it includes the page address, every input, and the result you expected. A sentence that says the payment looks high is hard to test. A sentence that says price 400000, down payment 80000, rate 7.26, term 30, and the principal and interest should be a number you name can be checked the same day.

Questions about a missing calculator are welcome. Name the decision you are trying to make and the inputs you already have. The library is finance math: loans, tax estimates, retirement, investing, and everyday money. It does not add medical or scientific calculators.

What happens to the message

The form opens your email app addressed to hello@iracalculator.net. The site does not store the message in an account system. You can also write to that address directly. Please do not include account numbers, passwords, or government identification numbers. A balance and a rate are enough to test a formula.

We read notes to fix bugs and to answer questions about a page. We do not add senders to a marketing list. The privacy policy describes the rest of what the site does and does not collect.

If you are writing about a 2026 limit, cite the figure you saw and the page. Retirement and tax tools follow the methodology: standard deduction, wage base, elective deferral, IRA limit, and HSA limit. A mismatch between a news article and this site is worth a note, because one of the two may be using a prior year.

Please allow the email to be a normal letter. The form does not attach files. Screenshots are unnecessary if the inputs are written out. We cannot log into your custodian, your lender, or your tax software, and we will not ask you for a password.

A hosting or indexing question is also fine. The public site is a Next.js application. Calculators and guides are generated as pages with their own titles, descriptions, and canonical URLs. The sitemap index is /sitemap.xml. Search is intentionally left out of the crawl. If a public URL 404s, send the address. A broken internal link is a bug, the same as a wrong payment.

More from what happens to the message

We cannot take a message that asks us to impersonate a lender, to hide a fee, or to produce a figure that disagrees with the formula on purpose. We can explain which field moves the headline. That is the whole of the help this address is for.

If you write in another language, include the calculator’s English title so we can find the page. The interface is English. The math does not depend on the language of the note, but the labels you quote should match the form.

This address is not a brokerage desk and not a tax hotline. We cannot tell you whether a Roth contribution is allowed at your income, whether a lender will approve a loan, or whether a repair should be capitalized. We can point you at the page that shows the arithmetic and at the assumption the page is willing to name.

If the note is about advertising or privacy, say so in the subject. The privacy policy explains the cookie notice and what an ad partner would do if ads are enabled. The contact form itself does not set an advertising cookie. It only prepares an email.

After you send the note, you do not need to calculate again for our sake. Keep your own copy of the inputs if the decision matters. We will reply to the email you sent from. Check the spam folder if a day passes on a reproducible bug, and send the same inputs once more rather than a different scenario.
