Study Notes
Juros (Interest Rates)
Types of Interest Rates
- Nominal Interest Rate: The rate of interest charged on a loan, without considering the compounding effect.
- Effective Interest Rate: The rate of interest that takes into account the compounding effect, resulting in a higher interest rate.
Simple Interest vs. Compound Interest
- Simple Interest: Interest calculated only on the initial principal amount.
- Compound Interest: Interest calculated on both the initial principal amount and any accrued interest.
Formula for Compound Interest
A = P(1 + r/n)^(nt)
- A: Future value
- P: Principal amount
- r: Nominal interest rate
- n: Number of times interest is compounded per year
- t: Time in years
Continuous Compounding
- Continuous Compounding: Interest is compounded continuously, rather than at discrete intervals.
- Formula: A = Pe^(rt)
Yield Curve
- Yield Curve: A graphical representation of the relationship between interest rates and time to maturity.
- Types of yield curves:
- Normal Yield Curve: Long-term interest rates are higher than short-term interest rates.
- Inverted Yield Curve: Short-term interest rates are higher than long-term interest rates.
- Flat Yield Curve: Interest rates are similar across different time periods.
Applications of Interest Rates
- Investing: Interest rates affect the return on investment.
- Borrowing: Interest rates affect the cost of borrowing.
- Risk Management: Interest rates are used to manage risk in financial markets.
Note: These notes provide a concise overview of the key concepts related to interest rates in financial mathematics.
