Planning and Projections

31 interactive calculators covering salary, tax, pensions, mortgages, investments, and more. See your real take-home pay, project retirement income, and understand how every deduction works.

Digital Legacy Vault

End-to-end encrypted storage for your important accounts, documents, and contacts. Set up next-of-kin access so the people who matter can find what they need.

The companion book

Zero: Financial Knowledge

The audiobook and guide that walks you through everything the UK education system missed — savings, pensions, mortgages, investments, tax, and more. Written in plain English for real people.
