ANNUITYby: LLOYD PSYCHE T. BALTAZAR

LESSON OBJECTIVESAt the end of the lesson, you are expected to:a. distinguishes between simple and general annuities;b. finds the future value and present value of both simple annuities andgeneral annuities; andc. calculates the present value and period of deferral of a deferred annuity.

DEFINITION OF TERMSANNUITY- a series of equal payments made at equal intervals of timePAYMENT INTERVAL- the period of time between successivepayments (e.g. monthly, quarterly)FUTURE VALUE- sum of future values of all the payments tobe made during the entire term of theannuity.TERM OF ANNUITY- the length of time between the beginningof the first payment period and the end ofthe last payment period.PRESENT VALUE- sum of present values of all the paymentsto be made during the entire term of theannuity

DEFINITION OF TERMSORDINARY ANNUITY- a series of payments where each periodic paymentis made at the end of the payment interval.SIMPLE ANNUITYGENERAL ANNUITY- is an annuity whose interest conversionperiod is equal to the payment interval.- is an annuity whose interest conversionperiod is not equal to the payment interval.Example:Monthly payments, and the interestis compounded monthlyExample:Monthly payments, but the interestis compounded semi-annually

GENERAL ANNUITY

STEPS IN SOLVING GENERAL ANNUITY1. convert the regular/periodic payment in general annuity intoits equivalent regular/periodic payment in simple annuity withrespect to the interest period;2. then use the formula for simple annuity.

DEFERRED ANNUITY

TERMINOLOGYDeferred Annuity- an annuity in which the first periodic payment is made after a certain interval of time,known as the deferral periodOrdinary Deferred Annuity- when deferral period ends one payment interval before the first periodic payment.The future value of a deferred annuity- is the accumulated value of the stream of payments at the end of the annuity period. Thisis the same procedure as future value of an ordinary annuity (both simple and generalannuity).The present value of a deferred annuity- is the discounted value of the stream of payments at the beginning of the deferral period.

Ordinary Deferred Annuity - when deferral period ends one payment interval before the first periodic payment. The future value of a deferred annuity - is the accumulated value of the stream of payments at the end of the annuity period. This is the same procedure as future value of an ordinary annuity (both simple and general annuity).
