Time is worth money A dollar today is worth more than a dollar in the future A dollar due in the future is worth less than a dollar today Interest earned = principal ? rate ? time (in years) Calculating Interest Rates (Cont.) Compound Interest Interest that accumulates during a year is added to the principal at year’s end, thereby earning more interest in the following year Banks automatically add interest earned to the principle at specified time intervals Future Value [FV]—amount today’s principle will be worth in “n” years after adding compounded interest of rate “r”. FV = principle(PV) ? (1 + r)n Calculating Interest Rates (Cont.) Compound Interest (Cont.) Present Value [PV]—amount a future sum of money in “n” years will be worth today after discounting back to the present at rate “r” Future value/(1 + r)n = present value Calculating Interest Rates (Cont.) Coupon Rate on Bonds Amount printed on the face of the bond Annual (semiannual) interest payment (coupon payment) Return based on face value of the bond, not amount paid for the bond Current Yield Yield on annual interest received based on purchase price of bond Ignores capital gain—difference between purchase price and amount when redeemed at matur
