  1. Future Value, Present Value and Interest Rates

  2. Future Value $100 + $100(0.05) = $105 PV + Interest = FV PV + PV*i = FV PV = Present Value FV = Future Value i = interest rate (as a percentage) Future Value in one year: FV = PV*(1+i)

  3. Future Value in two years $100+$100(0.05)+$100(0.05) + $5(0.05) = $105 + $105(.05) = $110.25 =Present Value of the Initial Investment(100) + Interest on the initial $100 in the 1st Year + Interest on the initial $100 in the 2nd Year + Interest on the $5 interest from the 1st Year in the 2nd Year = Value in 1st + Interest on Value in 1st Year In general, future value n years from now compounded at interest rate i FVn = PV*(1+i)n

  4. ComputingFutureValue at 5% Annual Interest

  5. Present Value Present Value (PV) is the value today (in the present) of a payment that is promised n years in the future. OR Present Value (PV) is the amount that must be invested today at annual interest rate i in order to have a specific amount n years in the future

  6. Present Value of an amount received in one year: Solving the Future Value Equation FV = PV*(1+i)

  7. Present Value of $FV received n years in the future:

  8. Present Value Example Present Value of $100 received in 2 ½ years and an interest rate of 8%. PV = $100 / (1.08)2.5 = $82.50 Note: FV =$82.50 * (1.08)2.5 = $100

  9. Important Properties of Present Value Present Value is higher: • The higher the future payment (FV) • The shorter the time period until payment. (n) • The lower the interest rate at which future receipts are discounted (i)

  10. Internal Rate of Return The Internal Rate of Return on an investment is the interest rate that equates the present value of its future cash flows with its cost.

  11. Internal Rate of Return A machine with a price of $1,000,000 that generates $150,000/year for 10 years. Solving for i, i=.0814 or 8.14% When future inflows are discounted at a rate of 8.14%, the present value of those inflows equals $1million

  12. Bond Pricing The price of a bond now is the Present Value of its promised payments in the future. • Payment stops at the maturity date (n years) • The last payment is for the face value (F) {or par value or principal} of the bond • In addition to repayment of principal, Coupon Bonds make annual payments (C) based on an interest rate, the coupon rate (ic), C=ic*F

  13. Bond Pricing A discount bond just has a $100 (face value, F) principle in n years. The present value or price of a discount bond, (PBP):

  14. Bond Pricing: Coupon Bond If a bond has n coupon payments (C), where C= ic * F, the Present Value (PCP) of the coupon payments is:

  15. Bond Pricing: Coupon Bond[Like n+1 of discount bonds] Present Value of Coupon Bond (PCB) = Present value of Yearly Coupon Payments (PCP) + Present Value of the Principal Payment (PBP)

  16. Bond Pricing The price of a bond and the interest rate are inversely related  the higher the interest rate, the lower the bond prices.

  17. Real and Nominal Interest Rates Nominal Interest Rate (i) Interest Rates expressed in current dollar terms. Real Interest Rate (r) Nominal Interest Rate adjusted for (expected) inflation, πe. Fisher Equation: i = r + πe or r = i - πe
