How to know if you can actually retire at 45
TL;DR: You need three things to check, not one: your real FIRE number (a multiple of annual expenses), whether your current trajectory actually reaches it by 45, and whether your withdrawal plan survives a 40+ year retirement, not just the 30-year horizon most rules assume.
The three checks, in order
- Your FIRE number — a multiple of your annual expenses, not your income
- Your trajectory — at your current savings rate and return assumption, do you actually reach that number by 45?
- Your withdrawal plan's durability — a 45-year retirement needs a more conservative withdrawal rate or a flexible strategy, since it will likely outlast the horizon most retirement rules were designed for
Why "I have $1 million" isn't enough information
Whether $1 million supports retiring at 45 depends entirely on your annual expenses — for some households that's comfortably early-retirement-ready, for others it's well short. The multiple, not the raw number, is what actually matters.

Is $1 million enough to retire at 45?
It depends entirely on your annual expenses — at $30,000/year in expenses it may be comfortably enough under a standard withdrawal assumption; at $80,000/year it likely isn't. The multiple of expenses is what determines this, not the raw savings figure.
Does healthcare change the math significantly for early retirement?
Often yes, especially in a country without universal healthcare — a realistic healthcare cost estimate before eligibility for any public program (like Medicare in the US) should be built into the expense side of the calculation.
