5.3: Compound Interest Flashcards
What is compound interest?
Interest that is earned on the principal amount invested and on any accrued interest.
How is compound interest different from simple interest?
Compound interest is earned on both the principal and the interest accrued over time, whereas simple interest is only earned on the principal.
What is the formula to calculate the future value (FV) using compound interest?
A: ( FV_n = PV_0 (1 + k)^n )
What does FVIF stand for and what does it represent?
Future Value Interest Factor (FVIF); it represents the future value of an investment at a given rate of interest for a stated number of periods.
How do you calculate the future value of $1,000 invested at 10% annual compound interest for 50 years (Example 5.4)?
A: ( FV_{50} = $1,000 (1 + 0.1)^{50} = $117,390.85 )
What is the main takeaway from Example 5.4 regarding long-term compound interest?
Compound interest over a long period can significantly increase the value of an investment compared to simple interest.
What are the drawbacks of using the RRSP Home Buyer’s Plan (HBP) according to Finance in the News 5.1?
A:
1. $25,000 isn’t a lot of money when buying a house.
2. You need to repay that money.
3. Paying back your HBP loan isn’t straightforward.
Q: How does the compound return differ from the simple average return?
A: Compound return assumes all future returns are reinvested, whereas the simple average does not.
What is a basis point?
A: 1/100 of 1 percent.
Why do many Canadians find it difficult to repay their HBP loans?
A: Many are unaware of the rules and may not designate their RRSP contributions as HBP repayments, leading to default.
What is the definition of discounting in finance?
Finding the present value of a future value by accounting for the time value of money.
In Example 5.5, how much does an investor need to invest today to have $1 million in 40 years at a 10% interest rate?
$22,094.93
What is the formula for finding the present value (PV) of a future value (FV)?
PV0 = FVn / (1 + k)^n
What does PVIF stand for and what does it represent?
Present Value Interest Factor (PVIF);
it determines the present value of $1 to be received at some time in the future based on a given interest rate and period.
