# Net Present Value (periodic cash flows)

Calculates of Net Present Value (NPV) of a series of **periodic** cash flows with an initial investment (C) followed by cash flows F_{1} F_{2} F_{3} ... .

`NPV = -C + F_1/(1+r)^i+F_2/(1+r)^2+F_3/(1+r)^3...`

If cash flows are non-periodic (custom dates), this calculator would be more adapted NPV with non-periodic cash flows.
