Compute the present value at 7% of a stream of cash flows occurring at regular time intervals:

Specify an interval at which cash flows occur:

Future value at 9% of a stream of cash flows occurring at irregular time intervals:

Find the net present value of a 1000ドル initial investment producing future incoming cash flows:

Convert an Annuity object to a Cashflow object:

Cashflow works with date expressions:

Specify Cashflow with a TimeSeries :

Cashflow works with symbolic parameters:

Solutions to equations involving Cashflow can be found in terms of symbolic parameters:

Calculate the duration of a series of cash flows using the derivative function D :

Internal rate of return of an investment with regular cash flows:

Find the payment at time 2 that will make the net present value of a series of cash flows zero:

Solve for the point in time where a payment of 400ドル will make the net present value equal to 0:

In return for receiving 600ドル at the end of 8 years, a person pays 100ドル immediately, 200ドル at the end of 5 years and a final payment at the end of 10 years. Find the final payment amount that will make the rate of return on the investment equal to 8% compounded semiannually:

Payments of 100,ドル 200ドル and 500ドル are due at the end of years 2, 3 and 8, respectively. Find the point in time where a payment of 800ドル would be equivalent at 5% interest:

Find the effective rate of interest at which the present value of 2000ドル at the end of 2 years and 3000ドル at the end of 4 years will be equal to 4000ドル:

A Cashflow object with one cash flow is equivalent to a simple amount:

Large cash flow sequences that obey a pattern can be generated through Annuity using a payment growth function:

Large cash flow streams can also be created using Table :

Use Plot and Plot3D to explore the various dependencies a series of cash flows has on a set of variables:

Dependence on interest rate:

Dependence on payment growth rate:

Use Plot3D to view the interest rate/growth rate landscape:

When specifying a valuation period in between payments of a Cashflow object, TimeValue calculates the future value of all cash flows before the valuation period, and the present value of all cash flows after the valuation period:

This is equivalent to the sum of present and future values here:

Cashflow [Annuity [pmt,n,q]] only works for numeric n and f:

Using numeric n allows Cashflow to convert the Annuity object as desired:

Use Manipulate to explore the various dependencies a series of cash flows has on a set of variables:

Plot the cash flows in a "sawtooth"-style cash flow stream together with the accumulated value as a function of time:
