## What is the difference between Ordinary Annuity and Annuity Due?

Annuities are a series of fixed payments made over a fixed period over regular intervals. Ordinary annuities and annuity due are two such types of annuities. There are, however, a number of differences between ordinary annuity and annuity due. While an ordinary annuity is paid at the end of the period, an annuity due is paid at the beginning of the period. If you are the party who is making the payment then an ordinary annuity is beneficial. On the other hand, if you are the party receiving the payment then an annuity due is beneficial. This is because of the principle of the time value of money. Due to rising levels of inflation, a dollar today is worth more than a dollar tomorrow. When making a payment, the more it can be delayed the less it will cost. In terms of receipts, the earlier you can obtain the funds the more it will be worth.
