섹션 1: 연산 메커니즘

이 계산의 원리 (알기 쉬운 설명)

Albert Einstein famously called compound interest the eighth wonder of the world. Unlike simple interest which only earns on principal, compounding earns interest on your prior interest. As the years progress, the growth curve turns vertical—your returns begin generating far more cash each year than your salary contributions.

섹션 2: 수식 및 수학적 가정

알고리즘 수식 및 수학적 근거

수학 공식:

A = P \left(1 + \frac{r}{n}\right)^{nt} + PMT \times \left[\frac{\left(1 + \frac{r}{n}\right)^{nt} - 1}{r/n}\right]

모델의 기본 가정:

Assumes monthly contributions are deposited on schedule at the end of each period.
Assumes reinvestment of all dividends and capital gains distributions.

전략적 조정을 통해 재정 궤적이 어떻게 달라지는지 확인하세요:

전략 A

Baseline Minimum Strategy

Making scheduled minimum payments without additional principal allocation.

Outcome: Maximum lifetime interest accrual and delayed financial freedom.

전략 B (최적화)

Accelerated Decision Strategy

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: 복리 계산기

How much difference does starting 5 years earlier make?

Due to exponential compounding, starting 5 to 10 years earlier can double your eventual retirement nest egg, even if you invest less total cash than someone who starts later.

What is the Rule of 72?

Divide 72 by your expected annual interest rate to find out how many years it takes for your money to double. At 8% return, your money doubles every 9 years (72 ÷ 8 = 9).
