Annuities and perpetuities are types of financial instrument, which make payments at regular intervals (parrino & kidwell, 2009). Although both perpetuities and annuities make regular payments, there is a difference in the life span of the financial instruments. Annuities have a finite lifespan while perpetuities have an infinite life span (Grinblatt & Titman, 2002). Examples of annuities are; loan repayment and lottery winning. For loan repayment, the principal and interest are repaid in regular intervals while in lottery winning the winner receives a fixed amount of the winning for fixed period. Example of perpetuity is a charity donation and a pension fund is a pension fund where an individual receives a fixed amount until death and his or her next of kin can continue receiving the pension on behalf of the deceased person.
