Çalışma Mantığı: Bileşik Faiz
Compound interest creates a snowball effect. As interest is added to your account balance, that interest earns interest in the next cycle. The frequency of compounding (daily, monthly, quarterly, or annually) determines how rapidly your investment grows.
Matematiksel Analiz ve Formüller
Bileşik faiz ile gelecekteki değeri hesaplamak için faiz oranı ve yatırım süresine dayalı bileşik faiz formülünü uygularız.
A is the future value of the investment, P is the initial principal, r is the annual interest rate (decimal), n is the compounding frequency per year, and t is the time in years.
Uygulamalı Örnekler
Example 1: Investing $10,000 at 6% compounded monthly for 10 years
- Principal (P): $10,000, Rate (r): 0.06, Frequency (n): 12, Years (t): 10
- Calculate rate factor: r ÷ n = 0.06 ÷ 12 = 0.005
- Calculate exponents: n × t = 12 × 10 = 120 months
- Apply growth: A = $10,000 × (1.005)^120 = $18,193.97
- Total Compound Interest earned: $8,193.97

- Underestimating Inflation: Forgetting that inflation reduces the purchasing power of your money over time.
Sıkça Sorulan Sorular (SSS)
Q: What is the Rule of 72?
A rule of thumb to estimate when an investment will double. Divide 72 by your annual interest rate. (e.g. at 6%, doubling takes 12 years).
Q: What compounding frequency is best?
The higher the compounding frequency (e.g. daily instead of annually), the faster your interest grows.
