Financial Independence
Having enough invested wealth that your ongoing living costs are covered without needing paid work, so continuing to work becomes a choice rather than a requirement.
A state, not a single event
Financial independence is the condition your FIRE number describes — the portfolio, once you're drawing from it at your chosen rate, covers your planned spending indefinitely (or for your specific retirement horizon, on a drawdown-to-zero basis). It's usually reached gradually as savings and investment growth close the gap, not on one identifiable day, which is why tracking progress toward it over time matters more than any single snapshot. Reaching it doesn't obligate you to stop working — many people keep working past the point where they technically could stop, precisely because it's now optional rather than necessary.
Why the number underneath it moves
"Enough" isn't a fixed figure. It depends on the withdrawal basis you've chosen (see safe-withdrawal-rate and drawdown-to-zero), your planned annual spend, how long the money needs to last, and any legacy amount you want left over. Change any of those inputs and financial independence itself doesn't change, but the pot size needed to reach it does — which is why Ember treats the FIRE number as something to recompute as your plan evolves, not a target fixed in stone at the start.
Related but distinct milestones
Financial independence, coast FIRE, barista FIRE and work-optional all describe points on the same spectrum, not synonyms. Coast FIRE means your existing savings will grow into your FIRE number without further contributions, but you're not there yet. Barista FIRE means part-time or lower-stress work still covers part of your spending, so the portfolio only funds the rest. Full financial independence is the point past both of those, where the portfolio funds your spending on its own.
Across borders
The same portfolio can mean financial independence in one country and fall short in another, because both sides of the equation move with residency: the tax owed on withdrawals changes your required pot (see safe-withdrawal-rate), and the cost of the lifestyle you're funding changes with where you actually live (see geoarbitrage). Two people with identical portfolios and identical spending habits can reach financial independence years apart purely because of where they're resident when they draw down.
Common questions
Is financial independence the same as retirement?
No. Retirement is a decision about whether to keep working; financial independence is the financial state that makes that decision optional. You can be financially independent and still working, and the "RE" in FIRE is a separate choice layered on top of the "FI."
How do I know when I've reached it?
When your investable portfolio, drawn down at your chosen withdrawal basis, would cover your planned spending for your full retirement horizon — in other words, when it matches or exceeds your FIRE number. Ember tracks that comparison as your plan's net worth and assumptions change, rather than treating it as a one-off calculation.
Does financial independence mean I never touch my portfolio again?
No — it means the portfolio can sustainably fund withdrawals at your chosen rate. You're still expected to draw from it; the point is that the drawing is sustainable without further paid income, not that the money sits untouched.
