Calculating the Present Value of Calculating the Present Value of an Annuity Duean Annuity Due
1) Find the present value of an ordinary annuity 1) Find the present value of an ordinary annuity factor (PVF-OA factor (PVF-OA @@ n=N-1, i=%) for n-1 n=N-1, i=%) for n-1 periodsperiods
2) Multiply that factor time (1+i), that is, 1 plus 2) Multiply that factor time (1+i), that is, 1 plus the interest rate -- to get the “PVF-AD” factorthe interest rate -- to get the “PVF-AD” factor
3) Multiply the periodic “amount” times this 3) Multiply the periodic “amount” times this PVF-AD to get the present value of paymentsPVF-AD to get the present value of payments
