Report an error, suggest a tool, or ask a question.
Use the form below to reach out. A few things that are particularly useful:
Note: We can't give legal, financial, medical, or veterinary advice. For those, please consult a qualified professional.
Usually within a couple of working days. If you're reporting an error in a calculator that could affect financial decisions, we prioritise those and aim to respond and fix the issue same day.
No — and we'd be doing you a disservice if we tried. The tools and guides here give you a solid starting point and help you understand the numbers, but your specific situation needs a qualified professional: a solicitor, financial adviser, accountant, or doctor. If you're not sure who to contact, the Citizens Advice Bureau (UK) or your state bar's referral service (US) can point you in the right direction.
Please report it using the form above, selecting "Error or wrong figure in a calculator." Include the tool name, the inputs you used, the result you got, and what you think the correct figure should be (with a source if you have one). We verify every report and fix genuine errors as quickly as possible.
Yes — tool suggestions are always welcome. The most useful submissions explain what the tool should calculate, what inputs it would need, and who would use it. If it's something that serves a real practical need and we can build it accurately, it goes on the list.
Each tool lives on its own subdomain (for example, qr.fluxmediasystems.com or stamp-duty-calculator.fluxmediasystems.com) and can be linked to directly. They're free to share. For embedding in a third-party site or commercial use, please get in touch first.
