Nilai Waktu dari Uang (The Time Value of Money)

Nilai Waktu dari Uang (The Time Value of

Money)

Sasaran

1. Dapat menjelaskan mekanisme pemajemukan, yaitu bagaimana nilai uang dapat tumbuh saat dinvestasikan, Menentukan Nilai Masa Depan (Future Value)

2. Menentukan Nilai masa depan (Future Value) atau nilai sekarang (Present Value) atas sejumlah uang dengan periode bunga majemuk yang non tahunan

3. Mendiskusikan hubungan antara pemajemukan dan membawa kembali nilai sejumlah masa sekarang (Present Value)

4. Mendefinisikan anuitas biasa dan menghitung nilai majemuknya atau nilai masa depan

5. Membedakan antara anuitas biasa dengan anuitas jatuh tempo sertamenentukan nilai masa depan dan nilai sekarang dari suatu anuitas jatuh tempo

6. Menghitung annual persentase hasil tahunan atau tingkat suku bunga efektif tahunan dan menjelaskan perbedaannya dengan tingkat suku bunga nominal seperti yang tertera

Konsep Dasar

1. Terjadi perubahan Nilai Tukar Uang dari waktu ke waktu

2. Keputusan Manajemen Keuangan melalui lintas waktu

Bunga Majemuk & DiscountedCompounding and Discounting Single Sums

Uang yg kita terima hari ini Rp. 100.000 akan bernilai lebih/ tumbuh dimasa yang akan datang . Ini sering di kenal sebagai opportunity costs.

Opportunity cost yang diterima Rp. 100.000 akan menjadi lebih dimasa yang akan datang karena adanya bunga

Today Future

Opportunity cost ini dapat di hitung

• Rp. 100.000 hari ini menjadi ? Di masa YAD / Future menjadi ? (compounding).

• Rp. 100.000 dimasa YAD = ? Hari ini (discounting).

1. Future Value /Nilai Masa Depan

Nilai masa depan investasi diakhir tahun ke n• FV dapat dihitung dengan konsep bunga

majemuk (bunga berbunga) dengan asumsi bunga atau tingkat keuntungan yang diperoleh dari suatu investasi tidak diambil (dikonsumsi) tetapi diinvestasikan kembali dan suku bunga tidak berubah

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!

Examples of Annuities:

• If you buy a bond, you will receive equal semi-annual coupon interest payments over the life of the bond.

• If you borrow money to buy a house or a car, you will pay a stream of equal payments.

The Time Value of Money

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.

Present Value of a Perpetuity

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

PV = PMT (PVIFA PV = PMT (PVIFA i, ni, n ) )

Mathematically,

(PVIFA i, n ) =

Mathematically,

(PVIFA i, n ) = 1 - 1 - 11

(1 + i)(1 + i)nn

Mathematically,

(PVIFA i, n ) =

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

1 - 1 - 11

(1 + i)(1 + i)nn

When n gets very large,

(1 + i)n

this becomes zero.1 -

(1 + i)n

this becomes zero.

So we’re left with PVIFA =

(1 + i)n

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

What should you be willing to pay in order to receive $10,000 annually forever, if you require 8% per year on the investment?

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.

APY = APY = (( 1 + 1 + ) ) m m - 1- 1quoted ratequoted ratemm

• Find the APY for the quarterly loan:

APY = APY = (( 1 + 1 + ) ) 4 4 - 1- 1.0785.078544

APY = APY = (( 1 + 1 + ) ) 4 4 - 1- 1

APY = .0808, or 8.08%APY = .0808, or 8.08%

.0785.078544

• The quarterly loan is more expensive than the 8% loan with annual compounding!

APY = APY = (( 1 + 1 + ) ) 4 4 - 1- 1

APY = .0808, or 8.08%APY = .0808, or 8.08%

PV: End mode; P/YR = 1; I = 20; PMT = 40,000; N = 5

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.

• How much do we need to have by the end of year 30 to finance the trip?

• PV30 = PMT (PVIFA .10, 5) (1.10) =

= 250,000 (3.7908) (1.10) =

= $1,042,470

250 250 250 250 250 250 250 250 250 250

Using your calculator,

Mode = BEGIN

PMT = -$250,000

I%YR = 10

P/YR = 1

PV = $1,042,466

2727 2828 2929 3030 3131 3232 3333 3434 3535

250 250 250 250 250 250 250 250 250 250

• Now, assuming 10% annual compounding, what monthly payments will be required for you to have $1,042,466 at the end of year 30?

2727 2828 2929 3030 3131 3232 3333 3434 3535

250 250 250 250 250 250 250 250 250 250

1,042,4661,042,466

Using your calculator,

Mode = END

N = 360

I%YR = 10

P/YR = 12

FV = $1,042,466

PMT = -$461.17

2727 2828 2929 3030 3131 3232 3333 3434 3535

1,042,4661,042,466

• So, you would have to place $461.17 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.
