Study Notes
Simple Interest and Simple Discount
- The formula for simple interest is: I = P rt
- The formula for simple discount is: P = S (1 - dt)
- The relationship between the simple interest rate and the simple discount rate is: r = 1 - dt
Compound Interest
- The formula for compound interest is: S = P (1 + rt)
- The formula for ordinary compound interest is: S = P (1 + j/m)^(mt)
- The formula for fractional compounding is: S = P (1 + j/m)^(mt) where t is a fraction of a year
Time Lines and Periods
- A time line is a graphical representation of the periods involved in a problem
- Periods can be expressed as a fraction of a year
- Days can be converted to years by dividing by 365
Calculations using the HP10BII Calculator
- Use normal mode for calculations
- Use the formula: I = P rt to calculate the accumulated interest
- Use the formula: S = P (1 + rt) to calculate the compound interest
Odd Period Calculations
- Use the method of fractional compounding to calculate the value of the total payments
- Express the odd periods as a fraction of a year
- Calculate the value of the payments at the specified month
Bond Pricing
- The formula for the all-in price of a bond is: P = danz + 100(1 + z)^(-n)
- The number of half years (n) can be calculated using the following tips:
- Determine the first coupon date after the settlement date
- Determine the number of half years until the maturity date
- Subtract the year of the next coupon date from the year of the maturity date to get the number of years until maturity
Perpetuity
- The formula for perpetuity is: P = R / i
- You will receive the payment R indefinitely
Deferred Annuity
- With a deferred annuity, you are unable to start to repay your debt immediately
- Your first payment is a number of payment intervals after the end of the first interest period
- First calculate the present value of the payments made and then discount this amount back to now by using compound interest
Amortisation
- Use the present value formula for annuities to determine the payment
- The formula for amortisation is: P = R [(1 + i)^(-n) - 1] / i
This quiz involves solving a problem related to financial mathematics, specifically calculating accumulated interest. It requires applying mathematical concepts to real-world financial scenarios.
