What to contact us about
BriskToolbox is a small, independent project, and we genuinely value hearing from the people who use it. Get in touch about any of the following:
- Feedback on a calculator or page — what worked, what was confusing, what could be clearer.
- Suggestions for new calculators you'd like us to build.
- Reporting an inaccuracy. If a result looks wrong, tell us — we take accuracy seriously and welcome corrections.
- General questions about the site or how a particular tool works.
Response time
We read every message and aim to reply within a few business days. To help us respond faster, it's useful to include:
- The calculator or page you're writing about (a link is ideal).
- For a suspected error: the exact inputs you used and the result you expected.
- For a request: the type of calculator you'd like us to add and what you'd use it for.
A quick note
BriskToolbox provides general information only and cannot give personalized financial, legal, tax, or medical advice. We're happy to explain how a calculator works, but we can't recommend what you should do in your specific situation — for that, please speak with a qualified professional.
Quick answers
Are the calculators free? Yes — every calculator on BriskToolbox is free to use, with no paywall.
Do I need an account? No. There's no sign-up and no login; you can use any tool right away.
