섹션 1: 연산 메커니즘

이 계산의 원리 (알기 쉬운 설명)

The FIRE movement relies on the Trinity Study's Safe Withdrawal Rate (SWR). At a 4% withdrawal rate (the Rule of 25), your target portfolio is 25 times your annual living expenses. Each year, you withdraw 4% of your nest egg to live on, allowing the remaining 96% to continue compounding in index funds and bonds.

섹션 2: 수식 및 수학적 가정

Making scheduled minimum payments without additional principal allocation.

Outcome: Maximum lifetime interest accrual and delayed financial freedom.

전략 B (최적화)

Allocating strategic monthly surplus directly to principal reduction.

Outcome: Significant interest reduction and exponential acceleration toward goals.

핵심 요점: Even modest monthly adjustments create substantial compound savings over multi-year horizons.

섹션 4: 한계 및 예외 조건

모델 한계 및 경계 조건

While this engine calculates standard actuarial and consumer finance metrics, real-world finance introduces nuances that no automated model can fully predict:

Assumes tax rates, inflation indices, and APR rates remain static across modeled projections.
Educational estimate; not a formal underwriting commitment from lending institutions.
Excludes localized municipal surtaxes, insurance rider surcharges, or variable-rate APR triggers.

자주 묻는 질문

자주 묻는 질문: FIRE 조기 은퇴 계산기

What is the difference between LeanFIRE, Regular FIRE, and FatFIRE?

LeanFIRE covers minimal survival expenses (~$40k/yr); Regular FIRE covers a comfortable average middle-class lifestyle (~$60k-$80k/yr); FatFIRE supports abundant travel and luxury without spending constraints ($120k+/yr).

What if market returns are lower in the future?

Many early retirees use a more conservative 3.25% to 3.5% safe withdrawal rate, which requires saving ~28x to 30x annual expenses to survive extended economic downturns.
