Hoe Werkt Samengestelde Rente
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.
Mathematische Analyse en Formules
Om de toekomstige waarde met samengestelde rente te berekenen, passen we de samengestelde renteformule toe op basis van het rentepercentage en de beleggingsperiode.
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.
Praktische Rekenvoorbeelden
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

Veelgestelde Vragen (FAQ)
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.
