**Nilai Waktu dari Uang (The Time Value of Money)**

2
Sasaran Dapat menjelaskan mekanisme pemajemukan, yaitu bagaimana nilai uang dapat tumbuh saat dinvestasikan, Menentukan Nilai Masa Depan (Future Value) Menentukan Nilai masa depan (Future Value) atau nilai sekarang (Present Value) atas sejumlah uang dengan periode bunga majemuk yang non tahunan Mendiskusikan hubungan antara pemajemukan dan membawa kembali nilai sejumlah masa sekarang (Present Value)

3
**Mendefinisikan anuitas biasa dan menghitung nilai majemuknya atau nilai masa depan**

Membedakan antara anuitas biasa dengan anuitas jatuh tempo sertamenentukan nilai masa depan dan nilai sekarang dari suatu anuitas jatuh tempo Menghitung annual persentase hasil tahunan atau tingkat suku bunga efektif tahunan dan menjelaskan perbedaannya dengan tingkat suku bunga nominal seperti yang tertera

**Hint for single sum problems:**

In every single sum future value and present value problem, there are 4 variables: FV, PV, i, and n When doing problems, you will be given 3 of these variables and asked to solve for the 4th variable. Keeping this in mind makes “time value” problems much easier!

Perpetuities Suppose you will receive a fixed payment every period (month, year, etc.) forever. This is an example of a perpetuity. You can think of a perpetuity as an annuity that goes on forever.

86
**Present Value of a Perpetuity**

When we find the PV of an annuity, we think of the following relationship:

87
**Present Value of a Perpetuity**

When we find the PV of an annuity, we think of the following relationship: PV = PMT (PVIFA i, n )

88
Mathematically,

89
Mathematically, (PVIFA i, n ) =

90
Mathematically, (PVIFA i, n ) = 1 - 1 (1 + i) n i

91
**1 - i Mathematically, 1 (PVIFA i, n ) = (1 + i)**

We said that a perpetuity is an annuity where n = infinity. What happens to this formula when n gets very, very large? 1 - 1 (1 + i) n i

92
When n gets very large,

93
When n gets very large, 1 - 1 (1 + i) n i

94
When n gets very large, this becomes zero. 1 - 1 (1 + i) n i

95
**1 - 1 i i When n gets very large, this becomes zero. 1 (1 + i)**

So we’re left with PVIFA = 1 - 1 (1 + i) n i 1 i

96
**Present Value of a Perpetuity**

So, the PV of a perpetuity is very simple to find:

Mathematical Solution: Simply compound the FV of the ordinary annuity one more period: PV = PMT (PVIFA i, n ) (1 + i) PV = 1,000 (PVIFA .08, 3 ) (1.08) (use PVIFA table, or) 1 PV = PMT (1 + i)n i PV = (1.08 ) = $2,783.26 .08 (1 + i) (1.08)

**Annual Percentage Yield (APY)**

Which is the better loan: 8% compounded annually, or 7.85% compounded quarterly? We can’t compare these nominal (quoted) interest rates, because they don’t include the same number of compounding periods per year! We need to calculate the APY.

**Annual Percentage Yield (APY)**

APY = ( ) m - 1 quoted rate m

Team Assignment Upon retirement, your goal is to spend 5 years traveling around the world. To travel in style will require $250,000 per year at the beginning of each year. If you plan to retire in 30 years, what are the equal monthly payments necessary to achieve this goal? The funds in your retirement account will compound at 10% annually.

**So, you would have to place $461**

So, you would have to place $ in your retirement account, which earns 10% annually, at the end of each of the next 360 months to finance the 5-year world tour.
