Money Engine is a collection of practical calculators for people in the UK who want to explore retirement, salary, budgeting, debt, property tax, and savings scenarios before making decisions. Every tool runs locally in your browser; your inputs are not sent to our servers.
Who it is for
Anyone who wants a clearer picture of their finances without signing up for an app or sharing personal data. The tools use published UK tax bands, student loan thresholds, stamp duty rates, and similar assumptions — see How we calculate for detail.
What we are not
Money Engine is general information and educational software. It is not regulated financial advice. Tax rules, interest rates, and personal circumstances change. Use these calculators to explore options, then check important decisions with qualified professionals or official sources.
Privacy-first by design
