Present value of an Annuity
Either:
PV = C x (1/r - 1/r x (1+r)^t )
Or PV= c x annuity factor
C = cash flow
R = interest rate
T= time
Future Value (FV)
FV = PV x (1+r)^t
Present value with annual compounding
PV = FV / (1+R)^t
Using discount factor
PV = FV x discount factor
Using annuity
PV= C x annuity factor
Annuity due
C x (1/r - 1/r x (1+r)^t ) x (1+r)^t
Present value today
PV = FV/ (1+r)^t
Future value of annuity
PV annuity x (1+r)^t
Effective interest rate
Effective interest rate = (1 + r/n) ^n -1
NPV of project
NPV of project = CF0 + CF x annuity factor
CF0 = initial investment
CF = cash flow
Profitability index
Profitability index = NPV / initial investment
NPV of year t today
NPV of year t today = NPVt / (1+r)^t
Pre tax profit
Pre tax profit = earnings - depreciation
Taxes
Taxes = tax rate x pre tax profit
Profit after tax
Profit after tax = pre tax profit - taxes
