2 Value of Investing \$1 –Continuing in this manner you will find that the following amounts will be earnt:

3 Value of \$5 Invested More generally, with an investment of \$5 at 10% we obtainMore generally, with an investment of \$5 at 10% we obtain

4 Future Value of a Lump Sum

5 Example: Future Value of a Lump Sum Your bank offers a CD with an interest rate of 3% for a 5 year investments. You wish to invest \$1,500 for 5 years, how much will your investment be worth?

6 Present Value of a Lump Sum

7 Example: Present Value of a Lump Sum You have been offered \$40,000 for your printing business, payable in 2 years. Given the risk, you require a return of 8%. What is the present value of the offer?You have been offered \$40,000 for your printing business, payable in 2 years. Given the risk, you require a return of 8%. What is the present value of the offer?

8 Solving Lump Sum Cash Flow for Interest Rate

9 Example: Interest Rate on a Lump Sum Investment If you invest \$15,000 for ten years, you receive \$30,000. What is your annual return?If you invest \$15,000 for ten years, you receive \$30,000. What is your annual return?

27 FV Annuity Formula: Payment

28 FV Annuity Formula: Number of Payments

29 Perpetual Annuities / Perpetuities Recall the annuity formula:Recall the annuity formula: Let n -> infinity with i > 0:

30 Mortgage: The payment We will examine this problem using a financial calculatorWe will examine this problem using a financial calculator The first quantity to determine is the amount of the loan and the pointsThe first quantity to determine is the amount of the loan and the points

31 Calculator Solution This is the monthly repayment

32 Calculator Solution Outstanding @ 60 Months

33 Summary of Payments The family has made 60 payments = \$2687.98*12*5 = \$161,878.64The family has made 60 payments = \$2687.98*12*5 = \$161,878.64 Their mortgage repayment = 450,000 - 418,744.61 = \$31,255.39Their mortgage repayment = 450,000 - 418,744.61 = \$31,255.39 Interest = payments - principle reduction = 161,878.64 - 31,255.39 = \$130,623.25Interest = payments - principle reduction = 161,878.64 - 31,255.39 = \$130,623.25
