Study Notes

Future Value

Future value represents the value of money at the stated time period.
It is calculated using the formula: FV = PV x (1+r)n.
Key variables include:
- PV: The present value of the money.
- r: The interest rate per period.
- n: The number of periods.
Future value calculations are helpful for determining the attractiveness of investments and the effect of inflation.

Present Value

The present value is the value today of a sum of money to be received in the future.
It is calculated by using the formula: PV = FV X [1/(1+r)n].
Key variables include:
- FV: The future value.
- r: The discount rate (interest rate).
- n: The number of periods.

Solving for Unknown Rate and Periods

The unknown rate (r) can be calculated using the formula: r = [FV/PV]1/n – 1
The number of periods (n) needed to reach a financial goal can be calculated using the formula: n = [ln(FV/PV)/ln(1+r)].

Applications of Time Value of Money

The time value of money can be applied to various scenarios including :
- Retirement savings, helping individuals determine the amount needed to save and the future value of their savings.
- Asset valuation, allowing calculations of the future values of assets and their growth potential.
- Loan cost determination, to determine the total cost of a loan with interest.
- Cash flow growth rate analysis, to understand the growth rate of cash flows over time.

The Single Period Scenario

The single-period scenario involves calculating the future value of a lump sum that will be received one period from today.
The formula: FV = PV(1+r) can be used.

The Multiple Period Scenario

The multiple-period scenario involves calculating the future value of a lump sum to be received in more than one period.
The formula: FV = PV x (1+r)n is used.
- In this formula, (1+r)n represents the future value interest factor (FVIF) for the given interest rate and number of periods.

Present Value and Discounting

Present value calculations involve discounting future cash flows back to their present-day value.
Discounting acknowledges that money received in the future is less valuable than money received today because it cannot be invested to earn interest in the present.
The present value formula PV = FV x 1/ (1+r)n is used to determine today's value of a future cash flow.

The Single Period Scenario for Present Value

The single-period scenario for present value involves calculating the present value of a lump sum received one period from today.
The formula: PV = FV/(1+r) is used.

The Multiple Period Scenario for Present Value

The multiple-period scenario for present value involves calculating the present value of a lump sum received in more than one period.
The formula: PV = FV x 1/(1+r)n is used.

Rule of 72

The Rule of 72 is a simple method for approximating the number of years needed to double an investment.
Divide 72 by the interest rate to estimate the number of years required.
For example, if the interest rate is 5%, it will take approximately 72/5 = 14.4 years for the investment to double.
