Free online tools built specifically for the United Kingdom — with the right tax bands, the right currency, and the right context.
Toolskit UK is a free collection of online tools built for people living and working in the United Kingdom. From mortgage calculators that use current UK interest rates to VAT calculators with HMRC's exact rates — everything on this site is designed with the UK user in mind.
We noticed that most tool websites are built for a global audience, which means the default currency is dollars, the tax calculations assume US law, and the content is generic. UK users constantly have to convert figures, check whether rates apply, or find that the calculator simply doesn't work for their situation.
Toolskit UK fixes that. Every tool is calibrated for the UK market, updated for the current tax year, and written in British English.
Toolskit UK currently offers tools in five categories:
We add new tools regularly based on what UK users search for most. If there's a tool you'd like to see, use the contact form to let us know.
Toolskit UK is funded by Google AdSense advertising. When you visit the site, you see relevant ads from Google's network. If you click an ad, we earn a small amount — typically a few pence to a few pounds depending on the niche.
This means:
The adverts are served by Google and are personalised based on your browsing history. You can opt out of personalised ads in your Google account ad settings.
Toolskit UK is an independent project. Every calculation has been verified against HMRC guidance, current UK law, and real-world examples. Finance calculators are updated every time the Chancellor announces a Budget change. If you spot an error or outdated figure, please get in touch — we take accuracy seriously.
We take every step to ensure our calculations are accurate and up to date. However, all results from Toolskit UK should be treated as estimates for guidance and planning purposes only. They do not constitute financial, legal or tax advice.
For important financial decisions — taking out a mortgage, calculating tax owed, or completing a VAT return — always verify with HMRC directly, or consult a qualified financial adviser, accountant or solicitor.
Tax rates, thresholds and regulations change regularly. While we update our tools promptly after Budget announcements, there may be a short delay. Always check the HMRC website for the definitive current figures.
