Study Notes
Compound Interest Calculations
- Formula: A = P(1 + r)t (where A = future value, P = principal, r = interest rate, t = time)
- Example: Investing $1,000 at 5% annual interest compounded annually for 3 years yields $1,157.63.
Effective Annual Rate (EAR)
- Formula: EAR = (1 + r/n)n - 1 (where r = nominal rate, n = number of compounding periods per year)
- Example: A nominal rate of 6% compounded monthly has an EAR of 6.17%.
Simple Interest
- Formula: I = P × r × t (where I = interest, P = principal, r = interest rate, t = time)
- Example: A $5,000 loan at 8% simple interest for 2 years results in a total amount owed of $5,800.
Present Value
- Formula: PV = FV / (1 + r)t (where PV = present value, FV = future value, r = discount rate, t = time)
- Example: The present value of $10,000 received in 5 years, discounted at 7% annually, is $7,129.86.
- Key takeaway: The present value is always less than the future value due to the time value of money.
Annuities
- Characteristics: Equal payments at fixed intervals over a specified period.
- Not a characteristic: Unlimited term.
- Example: 10-year ordinary annuity with annual $1,000 payments at 5% results in a future value of $13,207.57.
- Annuity Due: Payments occur at the beginning of each period. Present value is higher than the ordinary annuity for the same period and rate.
Loan Payments
- Formula: PMT = P × (r / (1 - (1 + r)-n) (where PMT = monthly payment, P = principal, r = monthly interest rate, n = number of payments)
- Example: A $20,000 car loan at 6% annual interest over 5 years requires a monthly payment of $386.66.
Rule of 72
- Purpose: Estimating the doubling time of an investment.
- Formula: Doubling Time = 72 / Interest Rate
Continuous Compounding
- Formula: FV = PV × ert (where FV = future value, PV = present value, r = interest rate, t = time, e = exponential base).
Bond Pricing
- Formula: P = ∑t=1T C / (1 + r)t + F / (1 + r)T (where P = bond price, C = coupon payment, r = yield to maturity, F = face value, T = time to maturity)
- Example: $1,000 face value bond paying $50 annually with a yield to maturity of 5% matures in 10 years has a price of $1,081.11.
Financial Statement Concepts
- Equity: Total assets minus total liabilities.
- Example: A company with $500,000 in assets and $300,000 in liabilities has $200,000 in equity.
- Debt-to-Equity Ratio: Measures financial leverage (proportion of debt to equity).
- Liquidity: Ability to convert assets to cash quickly.
Interest Rate Calculations
- Real Interest Rate: Nominal interest rate minus inflation rate.
- Example: Nominal rate of 7% with 3% inflation gives a real rate of 4%.
Depreciation
- Effect: Reduces asset value over time.
- Example: An asset worth $20,000 depreciating $4,000 annually is worth $12,000 after 3 years.
Sinking Fund
- Purpose: Savings for a future expense, often to pay off debt.
