About Every Money Tool
Clearer tools for important decisions.
Every Money Tool creates approachable UK calculators for pay, pensions, mortgages, tax and everyday financial planning. The aim is to make assumptions and trade-offs easier to understand before you take the next step.
How the calculators are designed
We separate calculation logic from the page interface, test calculation engines, and show the main result alongside the assumptions that drive it. Where rules are time-sensitive, such as UK tax thresholds, they are kept in versioned configurations rather than buried in the interface.
What calculator results mean
Results are illustrative estimates, not offers, forecasts, tax returns or personalised financial advice. Lenders, pension providers, HMRC and other organisations may use different data, rules and timing. Always check relevant terms and current official guidance before acting.
Sources and updates
Our UK tax calculator methodology links to official sources and records its verification date. We will add further sources and version information as the calculator library grows.
What is next
Every Money Tool is expanding its UK guides and calculator coverage. Future country-specific tools will live under their own country route so assumptions and rules remain clear.
