All Rights ReservedChapter 84 Time Value of Money I.Four Critical Formulas A.Future Value: value tomorrow of $1 invested today. B.Present Value: value today of $1 to be received “tomorrow”. C.Future Value of an Annuity: value several periods from now of a stream of $1 investments.

All Rights ReservedChapter 85 Important TVM Concepts A. Future Value 1. What $1 invested today should grow to over time at an interest rate i. 2. FV = future value, P = principal, i = int. rate. a. I = interest (dollar amount), I = P  i 3. Single interest: FV = P + I = P + P(i) = P(1+i) 4. Multiple Interest Periods: FV i,n = P (1+i) n b. (1+i) n = Future Value Interest Factor c. FV i,n = P  FVIF i,n

All Rights ReservedChapter 86 Important TVM Concepts B. Present Value; 1.The value today of $1 to be received tomorrow. 2.Solving the Future Value Equation for PV; a. PV = FV  (1+i) single period discounting. b. PV = FV  (1+i) n multi-period discounting. c. PV = FV  (1+i) -n common form. d. (1+i) -n = Present Value Interest Factor. e. PVIF = 1 / FVIF (and vice-versa for same i, n)

All Rights ReservedChapter 87 Important TVM Concepts C.Future Value of an Annuity (FVA) e.g. Retirement Funds: IRA, 401(k), Keough 1. A series of equal deposits (contributions) over some length of time. 2. Contributions are invested in financial securities; stocks, bonds, or mutual funds. 3. The future value of accumulation is a function of the number and magnitude of contributions, reinvested interest, dividends, and undistributed capital gains. FVA = PMT * FVIFA

All Rights ReservedChapter 88 Important TVM Concepts D.Present Value of an Annuity (PVA) 1.Insurance Annuities a. Provide recipient with a regular income (PMT) for a set period of time. b.The present value (PV) of the payments to be received is the price of the insurance annuity. c.PVA = PMT * PVIFA 2. Types of Annuities: a. Ordinary Annuity: payments received at end-of-period. b. Annuity Due: payments received at beginning-of- period

All Rights ReservedChapter 810 Computing FVA A.FVA formula: 1. FVA = P  ([(1+i) n - 1]  i) = P  FVIFA [(1+i) n - 1]  i = future value interest factor for an annuity or FVIFA i,n. annuity or FVIFA i,n. 1. Assumption; steady return rate over time and equal dollar amount contributions.

All Rights ReservedChapter 811 Computing PVA A.PVA formula: 1. PVA = P  ([1 - (1+i) -n ]  i) = P  PVIFA [1 - (1+i) -n ]  i = present value interest factor for an annuity or PVIFA i,n. annuity or PVIFA i,n. 1. Assumption; constant return rate over time and equal dollar amount distributions.
