Your financial information never leaves your browser. We couldn't see your data even if we wanted to.
We believe in being upfront about this. SmartBudgetUK.co.uk is free to use because the site is supported by Google AdSense advertising and, on some money-saving pages, affiliate links to services like energy comparison, cashback and ISA providers.
If you click an affiliate link and go on to use that service, we may earn a small commission — at absolutely no extra cost to you. Affiliate links are always clearly labelled "Affiliate link" wherever they appear. These partnerships never affect which tools we build or what advice we give: our calculators run entirely in your browser and are never influenced by any advertiser.
This is the same transparent model used by sites like MoneySavingExpert and MoneySuperMarket — free tools for you, funded by advertising and optional switching/comparison links.
SmartBudgetUK.co.uk is not regulated by the Financial Conduct Authority. All tools and content are provided for informational and educational purposes only and should not be taken as financial advice.
Our calculators help you understand your finances — but for personalised guidance on investments, pensions, mortgages or debt, always consult a qualified Independent Financial Adviser (IFA). You can find regulated advisers via the FCA Register or at MoneyHelper.org.uk (free government-backed guidance).
