Where to start

Start with take-home pay for a standard employment estimate. Use Income Tax or National Insurance to isolate one deduction, and the investment tools for dividends, gains or savings interest.

UK data and coverage

For non-savings income, choose the country that determines your tax treatment. Scottish Income Tax differs; the savings and dividend tools use UK-wide rules.

Each calculator explains the formula, includes a worked example and identifies the assumptions that can affect your result. Official rule tables and dated price references are linked on the relevant pages.
