The function cashflows computes the present value of a list of cash flows. The flows are given one per period, starting at period 1.

Since cashflows used to be part of the (now deprecated) finance package, for compatibility with older worksheets, this command can also be called using finance[cashflows]. However, it is recommended that you use the superseding package name, Finance, instead: Finance[cashflows].

$\mathrm{with}\left(\mathrm{finance}\right)\:$

$\mathrm{cashflows}\left(\left[100\,200\,50\right]\,0.1\right)$

$293.7640872$

$-95+\mathrm{cashflows}\left(\left[100\,200\,50\right]\,0.1\right)$

$198.7640872$

$\mathrm{npv}≔-95+\mathrm{cashflows}\left(\left[100\,200\,50\right]\,r\right)$

$\mathrm{npv}≔-95+\frac{100}{r+1}+\frac{200}{{\left(r+1\right)}^2}+\frac{50}{{\left(r+1\right)}^3}$

$\mathrm{fsolve}\left(\mathrm{npv}=0\,r\,0..2\right)$

$1.147236683$

$\mathrm{plot}\left(\mathrm{npv}\,r=0..2\right)$

The Finance[cashflows] command was introduced in Maple 15.
