A DCF values an asset as the present value of the cash flows it is projected to produce. Here the projection is level free cash flow of $100.00 per year.
projected FCF=$100.00
Projection timeline
The timeline shows the projected free cash flow in year 1, year 2, and year 3.
FCF1=FCF2=FCF3=$100.00
Projection note
The projection is an assumption you choose. The computed DCF value later is only a value under those stated assumptions.
