Found an error? Have a suggestion? We respond to every message — typically within 2 business days.
We welcome messages from users who find errors, want to suggest improvements, or need clarification on how a calculation works.
Please include: the page URL, the input values you entered, the result you received, and the result you expected. We investigate all reported errors within 24 hours and correct confirmed issues promptly.
We regularly add new tools based on user requests. Tell us what you'd like calculated and why current tools don't cover it. We prioritise suggestions with the broadest UK relevance.
Questions about how UK tax works, what a specific figure means, or how to interpret a result. We'll point you in the right direction — though we cannot give personal financial or tax advice.
Journalists, publishers or organisations interested in citing our data or partnering with UKCalc are welcome to get in touch. Please include your publication or organisation name.
