Fat FIRE Calculator
Fat FIRE is early retirement without belt-tightening — you keep a comfortable lifestyle, so the target is much higher. This scenario doubles typical spending to show what that demands.

What this scenario works out to
In this example setup, the FIRE target comes to about $2,400,000. At this savings rate you could reach it around age 59. Stopping work at 55, the money runs low around age 92, so leave a safety margin.
These figures use this scenario’s example starting numbers — adjust the calculator above for your own situation.
Reading your fat FIRE result
A fat FIRE target is large because every extra dollar of annual spending adds roughly 25 dollars to the number you need. That makes savings rate and time your main levers. The chart will likely show a later FIRE age than a lean plan at the same income — the trade-off for not cutting back. If the date is too far out, decide which matters more: the lifestyle, or retiring sooner.
Who it fits: high earners who want to keep a comfortable lifestyle in retirement and would rather work a few more years than cut back. It also suits those with variable big-ticket spending — travel, family support, healthcare.
Watch out for: how fast the target grows. Every extra unit of annual spending adds 25 to the number, so lifestyle creep pushes the date out quickly. Decide what spending is truly non-negotiable before locking in the target.

Common questions
- How much do I need for fat FIRE?
- Often 2–3× a lean FIRE target, because your spending is higher. Under the 4% rule it is still 25× your annual spending — that spending is just larger.
- Is fat FIRE worth it over lean FIRE?
- It buys a more comfortable, resilient retirement at the cost of working longer or earning more. The right answer depends on how much you value lifestyle versus an early exit.
- What withdrawal rate suits fat FIRE?
- A larger portfolio can absorb more volatility, but the 4% rule still applies. Many fat FIRE planners keep a cash buffer to avoid selling in downturns.
