About Quidkit

Quidkit is a free UK personal finance hub. One shared model ties together your salary, expenses, mortgage, goals and pension — enter your salary once and every screen updates live.

How we keep it accurate

Every tax figure is taken from official sources — gov.uk, gov.scot and Revenue Scotland — and is verified for the 2026/27 tax year (last verified 14 June 2026). Each rate is covered by automated tests so a future change can't silently break a calculation. See our methodology for the detail.

Our promise

No accounts, no tracking of your figures, no data sent to a server. Quidkit gives you information to understand your money — it is not financial advice.
