I run calcgeeks myself, so your message comes straight to me — not a support queue. After about 15 years in finance, helping people make sense of their money is what I enjoy, so whether it's a bug, a question, or an idea, I read everything.
The fastest way to reach me is email. I aim to reply within two business days.
What to include
You'll get a faster, more useful reply if you tell us:
- Which calculator you were using (the page title or link).
- What you entered and what result you got.
- What you expected instead, and why, if you have a source in mind.
Reporting an error
We take accuracy seriously. If you believe a calculator is producing the wrong answer, send the inputs and the result you got. We'll re-run it against the published formula, fix it if it's wrong, and credit you if you'd like. Math errors are the one kind of bug we treat as urgent.
Requesting a calculator
We're always expanding the library. If there's a calculation you do often and wish you didn't have to do by hand, describe it and we'll look at adding it — especially if you can point us to the formula it should use.
