If you are asked to compute the PV, FV or payment for an annuity due, and you already have the answer for an equivalent annuity, here is a short cut to get the answer for an annuity due quickly:

PV (Annuity Due) = PV Annuity x ( 1+ Discount rate)

FV (Annuity Due) = FV Annuity x (1 + Discount rate)

PMT (Annuity Due) = PMT (Annuity) / (1 + Discount rate)

Go ahead and check it out on your financial calculator! You can also work backwards - if you already know the answer for an annuity due you can find out the answers for an annuity. You can save time by not having to toggle between the BGN and END mode on a financial calculator. We recommend practising this concept before the exam day.
