Coast FIRE Calculator: The Complete Resource Hub
Coast FIRE is one of the most practical milestones in personal finance — the moment your invested portfolio, left alone, will compound to your retirement number by age 65. No more saving required. You can "coast" the rest of the way.
The Formula
Coast Number = Target Retirement / (1 + real_return)^years_to_65
Example: Want $1.25M at 65, currently 35, assuming 7% real return → Coast Number ≈ $164,000 invested today.

Why Coast FIRE Matters
Unlike Lean FIRE (extreme frugality forever) or Fat FIRE (massive savings required), Coast FIRE is achievable for normal earners and unlocks optional work without career sabotage.
