DESCRIPTION OE THE FOUR TIME VALUE OF MONEY CONCEPTS
Present value is the value of a cash flow today.
Usage when a single cash flow is to be discounted to today’s value.
Formula PV = FV / ((1+i) ^n))
Where, PV = Present value
FV = Future Value
i= interest rate per compounding period
n=period
PVIF = Present Value Interest Factor = (1/ ((1+i) ^n))
Example Mr A would receive $1,100 from Mr B after 1 year. Find the present value of the cash flow if Mr A’s interest rate is 10% p.a.
PV = 1100 / (1.1^1) = $1,000
Thus, the present value of cash flow to be received after 1 year is $1,000 today.
Present value of annuity is the value of a series of equal cash flow received in equidistant period, today.
Usage when a series of cash flow is to be discounted to today’s value.
Formula PV = (a/i) (1(1/ ((1+i) ^n)))
Where, PV = Present value
a = equal cash flow (annuity)
i= interest rate per compounding period
n=no. of annuities
PVIFA = Present Value interest factor of annuity = (1/i) (1(1/ ((1+i) ^n)))
If cash flow occurs at the beginning of period then the above formula is to be multiplied by (1+i)
Example Mr A would receive $1,000 from Mr B every year for 5 years. Find the present value of the cash flow if Mr A’s interest rate is 10% p.a.
PV = (1000/.1)(1(1/((1.1^5))) = $3,791
Thus, the present value of cash flow to be received every year for 5 years is $3,791 today.
Future value is the value of a cash flow in future.
Usage when value of a single cash flow is to be computed in future’s date.
Formula FV = PV ((1+i) ^n))
Where, PV = Present value
FV = Future Value
i= interest rate per compounding period
n=period
FVIF = Future Value Interest Factor = ((1+i) ^n))
Example Mr A would receive $1,000 from Mr B today. Find the future value of the cash flow if Mr A’s interest rate is 10% p.a.
FV = 1000 * (1.1^1) = $1,100
Thus, the future value of cash flow after 1 year is $1,100.
Future value of annuity is the value of a series of equal cash flow received in equidistant period, on a future date.
Usage when future value is to be computed for a series of cash flow.
Formula FV = (a/i) (((1+i) ^n)1)
Where, FV = Future value
a = equal cash flow (annuity)
i= interest rate per compounding period
n=no. of annuities
FVIFA = Present Value interest factor of annuity = (1/i) (((1+i) ^n)1)))
If cash flow occurs at the beginning of period then the above formula is to be multiplied by (1+i)
Example Mr A would receive $1,000 from Mr B every year for 5 years. Find the future value of the cash flow if Mr A’s interest rate is 10% p.a.
FV = (1000/.1) ((1.1^5)1)) = $6,105
Thus, the future value of cash flow to be received every year for 5 years is $6,105. 
Solve, using the Rule of 72: rate =6%, pv=$7,000, fv= $56,000. Solve for years.
