What Is Chubby FIRE?
Chubby FIRE sits between standard FIRE and Fat FIRE, typically defined as retiring on $80,000 to $150,000 per year. It is the strategy for people who want genuine financial independence without the radical frugality of Lean FIRE, while also not needing the $3 to $5 million portfolios that Fat FIRE requires. For most households, Chubby FIRE means a comfortable life: travel, dining out, a nice home, discretionary spending, no deprivation, but also no private jets or yacht club memberships.
The appeal of Chubby FIRE over Fat FIRE is timeline. Cutting from $200,000 per year to $100,000 per year in planned retirement spending halves your FIRE number and can shave a decade off your working career. Cutting from $100,000 to $50,000 might feel like deprivation. The $80,000 to $150,000 range is where many people find they can live very well without building the massive portfolios that Fat FIRE demands.
Chubby FIRE requires honest accounting of what a comfortable life actually costs. Many people overestimate future spending on some categories (clothing, commuting, work lunches) and underestimate others (travel, healthcare, home maintenance). The most useful exercise before targeting a Chubby FIRE number is to build a detailed retirement budget that reflects what you actually want to do, not a percentage of your current income.
How This Calculator Works
Chubby FIRE uses the same underlying formula as any FIRE calculation, applied to a comfortable mid-range spending target.
Personal Considerations
Anchoring bias is particularly strong in the Chubby FIRE range, because the target number feels large, typically $2 million to $4 million, and the brain anchors on that figure as an immovable ceiling. People in this range often feel simultaneously too far from their number and uncertain whether it is enough, a double-bind that the anchoring creates: the current portfolio feels inadequate (it is far from the target), while the target itself feels uncertain (what if I need more?). The antidote is tracking the withdrawal rate the current portfolio supports rather than the gap to an abstract target number. A portfolio of $1.5 million does not support $100,000 per year, but it does support $60,000 per year at 4%, which is useful information.
The arrival fallacy is the shadow side of the Chubby FIRE pursuit. People who spend years optimizing toward a specific number often find that reaching it produces a brief surge of satisfaction followed by a rapid return to baseline, paired with a new anxiety about whether $2.5 million is truly enough. The solution is not to abandon the goal but to deliberately build the retirement life alongside the financial plan, so the arrival has somewhere real to land. A retirement that is fully imagined, with people, projects, and purpose waiting, tends to feel more like freedom than one that is purely defined by a number.

Frequently Asked Questions
At $100,000 per year and a 4% withdrawal rate, a couple needs $2.5 million. At $120,000 per year, that rises to $3 million. The exact number depends entirely on your target spending, not your household size as an input to the formula.
Standard FIRE has no fixed spending definition, but the community typically assumes something in the $40,000 to $80,000 range. Chubby FIRE implies a more comfortable lifestyle, typically $80,000 to $150,000 per year, and the corresponding larger portfolio.
Absolutely. Healthcare is one of the most commonly underestimated retirement expenses, especially for those retiring before 65 and Medicare eligibility. If you are using the Healthcare Cost Bridge Calculator, run both in parallel to confirm your Chubby FIRE budget is realistic.
Bucket strategies affect how you manage withdrawals, not the total portfolio size you need. Your FIRE number is still determined by annual expenses divided by withdrawal rate. Bucket strategies can help with sequence-of-returns risk once you are retired but do not reduce the target itself.
