FIRE and traditional retirement

Traditional retirement, in the way benefits are built in the United States, means leaving full-time work somewhere around the early-to-mid 60s, then using Social Security, Medicare, and savings. FIRE means reaching a portfolio that covers spending earlier than that, sometimes decades earlier. The arithmetic can be identical. The years you have to cover without those public benefits are not.

What gets harder if you stop earlier

• The horizon is longer, so a withdrawal rate studied over 30 years is being asked to cover 40 or 50.
• Medicare does not start when you do. Health insurance is a spending line you have to price, not a rounding error.
• Social Security, if you delay it, needs a bridge. Claiming it early reduces the benefit. The statement on ssa.gov is the input. This site will not invent one.
• Contribution years disappear. Stopping at 45 means twenty fewer years of deposits and of wage growth. The Coast idea — save hard early, then stop contributing — is one response. It only works if the early saving actually happened.
• Penalty rules on retirement accounts matter more, because more of the spending years fall before 59½. Roth contribution basis, taxable accounts, and exceptions in the tax code are the usual educational topics. They are easy to get wrong. A tax guide or a preparer beats a blog list.

What does not change

Spending still sets the number. A traditional retiree with expensive tastes and an early retiree with modest tastes can have the same portfolio need. The label FIRE does not shrink a budget. Compounding still rewards earlier contributions. And a constant-return spreadsheet still flatters both of them.

Leaving work is a life decision. This page only lists the financial pieces that move when the date moves.
