Financial independence is the point where your invested wealth generates enough income to cover your living costs, whether or not you keep working. It's not about a specific age or a specific bank balance — it's a ratio between what you spend and what your investments can sustainably produce.
A widely used rule of thumb is to target a portfolio of 25 times your annual expenses, based on the idea that withdrawing 4% of that portfolio per year is sustainable over a long retirement without running out of money. If your annual expenses are £24,000, the rule points to a target portfolio of roughly £600,000.
This rule was originally derived from US market data, so treat it as a starting estimate, not a guarantee. Use the Financial Independence Calculator on this site to model your own numbers.
Most UK residents will also receive the State Pension — the full new State Pension is £241.30 a week (around £12,547.60 a year) in 2026/27, uprated each year under the triple lock, and based on your National Insurance contribution record rather than what you've personally saved. You can currently claim it from State Pension age, which is 66 and scheduled to rise further in the coming decades.
Because the State Pension starts years after most people target for financial independence, the earlier retirement years usually need to be funded entirely from your own ISA and SIPP savings — a gap worth planning for explicitly, not assuming away.
Financial independence and retirement aren't the same thing — plenty of people reach financial independence and keep working, just without needing the paycheque. What changes is the optionality: work becomes a choice, not a requirement.
