Money Engine is a collection of practical calculators for people in the UK who want to explore net worth, retirement, salary, budgeting, debt, property tax, and savings scenarios before making decisions. Every tool runs in your browser; your inputs are not sent to Money Engine’s 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 provides financial planning calculators and modelling tools. We are not FCA-authorised and do not provide regulated financial, tax or investment 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
Settings and form inputs are stored on this device, or on your Google Drive if you choose to sync. Optional Google Analytics loads only after you accept cookies. Read our privacy and terms for the full picture.
