A trusted resource for UK financial tools since 2018
UK Calculator was launched to help UK residents better understand their personal finances — from working out take-home pay and tax liabilities to calculating mortgage repayments and property costs. We recognised that too many people were relying on outdated or inaccurate online tools, so we built a suite of calculators designed by financial professionals and updated annually in line with HMRC guidelines.
Every calculator on this site is built and maintained by our team, which includes qualified accountants, tax advisers and software developers. Our income tax, salary and National Insurance calculators are verified against current HMRC rates each April and cross-checked throughout the year when legislation changes. UK Calculator Ltd is registered in England and Wales (Company No: 15847293) with our registered office at 128 City Road, London, EC1V 2NX.
