What we do
UK Calculators helps you explore everyday financial questions. Our categories cover Money & Tax, Mortgages & Property, Business, Savings & Investments, Loans & Credit and Everyday Calculators. The directory lists the tools currently available.
How we build calculators
We use published rules and rates where relevant, show the assumptions behind each estimate and provide worked examples and source links. Rate-sensitive pages identify their tax year or rate period and review date, so you can see which information was used.
Independence
UK Calculators is an independent website, not affiliated with, endorsed by or connected to HM Government, HMRC or any UK public body.
Accuracy and updates
Figures are estimates, not guarantees. Rules can change and a calculator cannot account for every personal circumstance. Check important decisions against official sources or with a qualified professional.
How the site is funded
The site is free to use and may be supported by advertising. Advertising does not determine calculator outputs or editorial explanations.
