Direct answer: FIRE target = annual expenses / withdrawal rate. For $60,000 spending and 4% withdrawal, target corpus is $1,500,000; lower withdrawal rates increase required capital materially.
Source context: the 4% framework derives from historical safe-withdrawal research (often linked to Trinity-style studies) and should be stress-tested for inflation, sequence risk, and valuation regimes.
Different approaches to financial independence. All use 4% withdrawal rate.
| Type | Typical Spending | FIRE Number (4%) |
|---|---|---|
| Lean FIRE | $30K–$50K/year | $750K–$1.25M |
| Traditional FIRE | $50K–$80K/year | $1.25M–$2M |
| Fat FIRE | $100K+/year | $2.5M+ |
| Barista FIRE | Part-time income covers gap | Lower (gap ÷ 4%) |
| Coast FIRE | Stop contributing, growth carries you | Today's target for future date |
The 4% rule is based on historical US stock/bond returns. It can underperform when:
Your FIRE number is the portfolio size that supports your annual expenses at your chosen safe withdrawal rate (e.g. 4%): FIRE number = expenses ÷ withdrawal rate. The calculator projects your balance year by year in real terms (after inflation): each year you add your savings (income − expenses) and apply your expected real return. When your balance reaches the FIRE number, you have reached financial independence.
The 4% rule (Trinity Study) suggests you can withdraw 4% of your portfolio annually with a high probability of not running out over 30 years. Some use 3–3.5% for longer retirements. A lower rate means a higher FIRE number and typically more years to get there.
The calculator uses real return (after inflation) so that your FIRE number and timeline are in today's purchasing power. Real return = (1 + nominal return) / (1 + inflation) − 1. Your annual savings are assumed constant in real terms.
If you reach your FIRE number by or before your target retirement age, you are on track. If not, the calculator shows that you need to save more: consider a higher savings rate, lower expenses, a later target age, or (with caution) a higher expected return assumption.
Using a 4% withdrawal rate, the target portfolio is $1,500,000 because $60,000 / 0.04 = $1,500,000. With a 3.5% withdrawal rate, the target rises to about $1,714,000. Lower withdrawal rates provide more safety but require more capital.
A 50% savings rate can make a 15-year FIRE timeline possible, especially with consistent investing and 6% to 7% long-run returns. For example, saving $50,000 per year from a $100,000 income can build around $1.25 million in 15 years at 7% assuming no starting balance. Required time changes significantly with market returns and spending needs.
Lean FIRE typically targets lower annual spending, often around $30,000 to $50,000 for a household, while Fat FIRE targets higher spending such as $100,000 or more. At 4%, those imply portfolios of about $750,000 to $1,250,000 for Lean FIRE and $2,500,000+ for Fat FIRE. The right target depends on your expected lifestyle and location costs.
Inflation directly increases the spending number your portfolio must support. If annual spending rises from $60,000 to $75,000, the 4% FIRE target increases from $1,500,000 to $1,875,000. That is a $375,000 increase in required assets from spending inflation alone.
Barista FIRE: you have enough invested to cover the gap between part-time income and expenses. You quit full-time work and supplement with part-time (e.g., barista). Coast FIRE: you have enough today that, without adding more, growth will reach your full FIRE number by retirement age. You keep working but stop saving. Barista needs less capital; Coast needs more upfront.
The 4% rule can underperform with bad sequence of returns (market crash early in retirement), higher inflation than historical, longer than 30-year retirement, or lower future returns. Many retirees use 3–3.5% for extra safety, especially if retiring before 50.
Depends on your spending and withdrawal rate. At $60,000/year spending and 4% withdrawal, you need $1.5M. At 50% savings rate from $100K income, you save $50K/year; at 7% return, that builds ~$1.25M in 15 years from $0. Use the calculator with your numbers.
