Planning Your FIRE Journey
FIRE (Financial Independence, Retire Early) is a financial strategy focused on aggressive saving and investing to build a portfolio large enough to sustain your lifestyle without employment income. The FIRE calculator helps you determine your target portfolio size (FIRE number), estimate how many years it will take to get there, and track your progress. Unlike traditional retirement planning which assumes retirement at 65, FIRE planning often targets ages 35-55, requiring a larger portfolio and more conservative withdrawal rate to sustain decades of retirement.
The FIRE movement encompasses several variations tailored to different lifestyles and risk tolerances. LeanFIRE targets minimal expenses ($25,000-$40,000/year), FatFIRE aims for a comfortable lifestyle ($80,000-$200,000+/year), CoastFIRE saves enough early that compound growth alone will fund traditional retirement, and BaristaFIRE supplements passive income with part-time work. Understanding your FIRE variant helps set appropriate savings targets and withdrawal strategies.
With a 50% savings rate ($45,000 saved on $90,000 income) and 7% returns, you can reach financial independence in about 15 years. Every $10,000 reduction in annual expenses both increases your savings by $10,000 and reduces your FIRE number by $285,714 (at 3.5% withdrawal rate).

| Regular FIRE | $40,000-$60,000 | $1.14M-$1.71M | Moderate, balanced lifestyle |
| FatFIRE | $80,000-$150,000 | $2.29M-$4.29M | Comfortable, few compromises |
| ChubbyFIRE | $60,000-$80,000 | $1.71M-$2.29M | Between regular and fat FIRE |
| BaristaFIRE | Varies | Lower (supplement with PT income) | Part-time work covers some expenses |

FIRE Planning Strategies
Optimize Your FIRE Plan
Accessing Retirement Accounts Before 59.5

FIRE in Canada
Canadian FIRE seekers benefit from the TFSA (no tax on withdrawals at any age), universal healthcare (major expense eliminated), and CPP/OAS as a future guaranteed income floor. However, RRSP funds are taxed on withdrawal and must convert to a RRIF by age 71 with mandatory withdrawals. Canadian FIRE strategy: maximize TFSA first (tax-free access), use non-registered accounts for bridge years, then draw RRSP/RRIF in lower-income years. The FHSA (First Home Savings Account) offers additional tax-advantaged savings. Canadian FIRE planners should model their withdrawal strategy across TFSA, RRSP, and non-registered accounts to minimize lifetime taxation.
FIRE planning involves significant uncertainties: sequence of returns risk (poor early returns can devastate a portfolio), healthcare cost inflation, lifestyle changes, relationships and family changes, policy changes (taxes, Social Security), and decades of longevity risk. Build in a margin of safety by targeting a 3-3.5% withdrawal rate, maintaining flexibility to adjust spending, and considering part-time work as a bridge.
