Formula:

Key Capital Budgeting Formulas:

  • Net Present Value (NPV):
    NPV = Σt=1n [CFt / (1 + r)t] - Initial Investment
    Where: CFt = Cash Flow in year t, r = Discount Rate, n = Number of Periods, Initial Investment = Initial cash outlay.
  • Internal Rate of Return (IRR):
    IRR is the discount rate 'r' at which NPV = 0.
    0 = Σt=1n [CFt / (1 + IRR)t] - Initial Investment
    (Calculated iteratively to find 'r')
  • Payback Period:
    The time required for an investment to generate cash flows sufficient to recover its initial cost.
    Payback Period = (Full Years Before Recovery) + (Unrecovered Cost at Start of That Year / Cash Flow in That Year)
  • Profitability Index (PI):
    PI = (Present Value of Future Cash Flows) / |Initial Investment|
    Where: Present Value of Future Cash Flows = Σt=1n [CFt / (1 + r)t]
