Study Notes
Interest Rates and Debt Instruments
- The nominal interest rate is the rate of interest before adjusting for inflation.
- The Fisher equation states that the real interest rate is equal to the nominal interest rate minus the expected inflation rate.
- The real interest rate is considered more important for economic decisions because it reflects the true purchasing power of the borrower.
Debt Instruments and Cash Flows
- Cash flows refer to the stream of payments made over time in a debt instrument, such as a loan or bond.
- In a simple debt instrument like a loan, the principal is the initial amount borrowed.
Calculating Future Value and Yield to Maturity
- The formula to calculate the future value of a loan after one year is FV = PV x (1 + i), where FV is the future value, PV is the present value, and i is the interest rate.
- The yield to maturity on a loan is the total return on investment, considering the interest rate and the timing of payments.
- In the example where $100 is borrowed and the borrower has to pay back $110 after one year, the yield to maturity is 10%.
Discounting the Future and Present Value
- Discounting the future refers to the concept of reducing the value of future cash flows to their present value, taking into account the time value of money.
- The formula PV = FV / (1 + i)^n represents the present value of a future cash flow, where PV is the present value, FV is the future value, i is the interest rate, and n is the number of periods.
Simple Interest Rate and Loan Calculation
- The simple-interest rate refers to the interest rate charged on the initial principal amount of a loan.
- Calculating the simple-interest rate involves multiplying the principal amount by the interest rate to determine the interest paid over a period.
