Discrete Compounding Cash Flow Formulas

Single Payment

Compound Amount

Converts a single payment (or value) today - to a future value.

F = P [(1 + i) ⁿ ]                  (1)

where

F = future value

P = single payment today

i = interest rate per period

n = number of periods

Example - Future Value of an Initial Amount Received Today

An amount of 5000 is received today. Calculate the future value of this amount after 7 years with interest rate 5% .

The interest rate can be calculated

i = (5 %) / /100 %)

= 0.05

The future value of the amount can be calculated

F = (5000) [(1 + 0.05)⁷ ]

= 7036

P - single payment today

i - interest (%)

n - number of periods

Note that interest rate in % is used in the calculator - not in the equation.

Present Worth (or Value)

Converts a future payment (or value) - to present wort (or value).

P = F [(1 + i) ^-n ]                  (2)

where

P = present value

F = single future payment

i = discount rate per period

n = number of periods

Example - Present Value of a Future Payment

An payment of 5000 is received after 7 years . Calculate the present worth (or value) of this payment with dicount rate 5% .

The discount rate can be calculated

i = (5 %) / /100 %)

= 0.05

The present worth of the future payment can be calculated

F = (5000) [(1 + 0.05) ^-7 ]

= 3553

Uniform Series

Compound Amount - Annuity

Converts a uniform amount (annuity) - to a future value.

F = A [((1 + i) ⁿ - 1) / i ]                 (3)

where

F = future value

A = uniform amount per period

i = interest rate

n = numbers of periods

Example - Present Value of Uniforms Payments

An uniform amount of 5000 is paid every year in 7 years . Calculate the future value of this amount with interest rate 5% .

The interest rate can be calculated

i = (5 %) / /100 %)

= 0.05

The future value of the annuity can be calculated

F = 5000 [((1 + 0.05)⁷ - 1 ) / 0.05]

= 40710

Sinking Fund

Converts a specific future value to uniform amounts (annuities).

A = F [i / ((1 + i) ⁿ - 1)]                 (4)

where

A = uniform amount per period

F = future value

i = interest rate

n = number of periods

Example - Uniforms Payments required to reach a Future Value

The future value of a 7 years annuity is 5000 . Calculate the required annuity to reach this value with interest rate 5% .

The interest rate can be calculated

i = (5 %) / /100 %)

= 0.05

The uniform payments (annuity) can be calculated

A = 5000 [0.05 / ((1 + 0.05)⁷ - 1)]

= 614

Present Worth

Converts a uniform amount (annuity) - to a present value .

P = A [((1 + i) ⁿ - 1) / ( i (1  + i) ⁿ )]                   (5)

where

P = present value

A = amount per interest period

i = discount rate

n = discount periods

Example - Present Value of Uniform Amounts

The uniform amount (annuity) paid from a 7 years project is 5000 . Calculate the present value with interest rate 5% .

The interest rate can be calculated

i = (5 %) / /100 %)

= 0.05

The present value of the uniform amounts can be calculated

P = 5000 [((1 + 0.05)⁷ - 1) / ( 0.05 (1 + 0.05)⁷ )]

= 28932
