Unformatted text preview: , the subscripts are only to differentiate when the cash flows begin. The cash flows are all the same amount.) ….. C3 C2 C1 C1 C2 C1 Thus, each of the increased cash flows is a perpetuity in itself. So, we can write the cash flows stream as: C1/R C2/R C3/R C4/R …. So, we can write the cash flows as the present value of a perpetuity with a perpetuity payment of: C2/R C3/R C4/R …. The present value of this perpetuity is: PV = (C/R) / R = C/R2 81 So, the present value equation of a perpetuity that increases by C each period is: PV = C/R + C/R2 75. Since it is only an approximation, we know the Rule of 72 is exact for only one interest rate. Using the basic future value equation for an amount that doubles in value and solving for t, we find: FV = PV(1 + R)t \$2 = \$1(1 + R)t ln(2) = t ln(1 + R) t = ln(2) / ln(1 + R) We also know the Rule of 72 approximation is: t = 72 / R We can set these two equations equal to each other and solve for R. We also need to remember that the exact future value equation uses decimals, so the equation becomes: .72 / R = ln(2) / ln(1 + R) 0 = (.72 / R) / [ ln(2) / ln(1 + R)] It is not possible to solve this equation directly for R, but using Solver, we find the interest rate for which the Rule of 72 is exact is 7.846894 percent. 76. We are only concerned with the time it takes money to double, so the dollar amounts are irrelevant. So, we can write the future value of a lump sum with continuously compounded interest as: \$2 = \$1eRt 2 = eR t Rt = ln(2) Rt = .693147 t = .693147 / R Since we are using percentage interest rates while the equation uses decimal form, to make the equation correct with percentages, we can multiply by 100: t = 69.3147 / R 82 Calculator Solutions 1.
