We are glad to hear from you - particularly if you have spotted something that needs fixing, or there is a calculator you would like us to add.
Report a correction
Accuracy matters to us. If a figure or result looks wrong, please email us with the calculator name and what you expected to see. We investigate every report.
Suggest a calculator
If a tool you need is not on the site yet, tell us. We add calculators based on what people actually search for, so suggestions genuinely shape the site.
The best way to reach us is by email: hello@onlinecalculators.co.uk
We read everything that comes in and aim to reply within a few working days. Corrections are prioritised.
What we cannot help with
We cannot give personal financial, tax, legal or medical advice. Our calculators provide general estimates only - for advice on your specific situation, please speak to a qualified professional. See our disclaimer for more.
