Freedom Number Calculator

Two numbers matter more than any other in this book: the point where your essential expenses are covered for life — your optionality milestone — and the point where your whole lifestyle is. Enter your spending and current portfolio below to see both, and how close you already are.

Your numbers

Pull essential spending and total spending from your Cash Flow Tracker (Chapter 2) if you've already built one — otherwise, a good estimate is fine to start.

£

Housing, food, utilities, insurance, minimum debt payments — what you cannot live without.

£

Essentials plus everything discretionary — your full current lifestyle.

£

Pensions, ISAs / investment accounts, and other invested assets — not your emergency fund.

£

Optional — used only to estimate how many years remain at your current pace.

Track your progress

Save a snapshot of your portfolio value each quarter alongside your net worth and cash flow check-ins — watching this line close the gap is, for most readers, the most motivating number in the whole book.

    How this works: the 25× figure (at a 4% withdrawal rate) is a widely used planning estimate, not a guarantee — see Chapter 6, Section 6.3, for the nuance behind it. Your entries and saved snapshots live only in this browser's storage; download a CSV copy if you want a backup or to fold these numbers into your Financial Independence Tracker.
