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 initial investment producing future incoming cash flows:

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

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

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

Convert an Annuity object to a Cashflow object:

Cashflow works with date expressions:

Cashflow works with symbolic parameters:

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

Specify Cashflow with a TimeSeries:

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

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:

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

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

At what effective rate of interest will the present value of $2000 at the end of 2 years and $3000 at the end of 4 years be equal to $4000:

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

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:
