\mbox{NPV} = - \mbox{I}_0 + \mbox{DCF} = - \mbox{I}_0 + \sum_{i=1}^n \frac{\mbox{FCF}_i}{(1+r)^i} = \sum_{i=0}^n \frac{\mbox{FCF}_i}{(1+r)^i}



total number of accounting periods 

i= 0, 1, 2, 3, ...

running number of accounting period (usually 1 year)


discount rate

\mbox{FCF}_i = \rm CashIn_i - \rm CashOut_i

free cash flow generated during the i-th accounting period
