🇬🇧 Lite edition — global model

Financial freedom, calculated honestly.

A free, open-math calculator for anyone in the UK figuring out their number. This lite edition uses a simplified global growth model — it doesn't yet model ISA allowances or workplace pension auto-enrolment yet — it treats all your savings as one growing pot.

This is the lite edition: honest compound-growth math, but no the UK-specific tax or retirement-scheme modeling yet. Vote for the deep the UK edition →

What you actually put toward savings and investing each month.
What you expect to actually spend per year once retired, in today's money.
Higher stock allocation means higher expected growth but a bumpier ride.
Real annual return: stocks / bonds. Historical is based on 20th-century US market data; cautious is more conservative.

Monthly gap to close
UK savers typically split saving between ISAs (tax-free) and workplace pensions (tax-relieved, employer-matched). This lite model doesn't split the two — the deep edition will.
