An annuity can be defined as an insurance agreement between an insurer and an individual. Under this type of agreement, an insurer promises to pay an annuitant a certain amount of money in return for regular payments. In other words, an annuity provides an income stream that pays out payments over time. The annuitant receives periodic payments determined at the time of the agreement. The term of the annuity is determined at the time of signing of contract.

Basically, the present value of an annuity depends on how the payments are made over time. The present value is equal to the amount of payments received less the amount of payments earned at the time of purchase minus the initial investment. Also, the annuitant receives an equal amount for each payment. The higher the discount period, the lesser of the present value of the annuity

Annuities can be of different types such as single premium, variable universal life (VUL) and indexed. The type of annuity that a person chooses also depends on the period of time for which it is payable. For instance, fixed payments annuities are applicable only for a fixed number of years and progressive annuities provide additional payments throughout the tenure.

Annuities can be of various types including, interest guaranteed, deferred annuities, unitary, endowment, life and other tax deferred annuities. Deferred annuities allow investors to postpone receiving the interest payments until they reach a certain age. On the other hand, life annuities give fixed payments throughout the lifetime of the annuitant and are a popular choice. Other types of annuities include tax deferred, unitary, endowment, renewable and prepaid annuities.

Annuity payments are made to the holder on an annual basis. The annuitant is allowed to choose the term of payment and the rate of interest. In some cases, a combination of terms can be chosen, e.g., a fully amortizing, semi-amortizing, and fully amortizing plan. A PV is a percentage of the present value of a sum insured.

Annuity payments are tax-qualified, which means they can be taxed as regular income. They cannot be tax deflected. There are two exceptions to this rule; the Roth and the traditional qualified plans. When an investor opts for a Roth plan, the income tax part is excluded and the value of the annuity increases directly as a result.

On the other hand, in the traditional qualified plan, the present value of the premiums is used in the computation of the earnings before retirement. When amortizing a traditional annuity payment, the amortization calculator uses a mathematical equation to calculate the present value of the annuity payments. This method is used because it allows the owner of the annuity to adjust the rate of interest or the period of repayment during the payment of the annuity payment. For this reason, the present value of the amortization can vary greatly, and the payment of the annuity can become very low if the interest rate is too low.

The present value of an annuity is the amount by which the present value of future payments less the accumulated interest would change over time without reducing the value of the annuity. The calculation is also called the present value of the plan. It can be calculated by using the following variables: rate of interest, current interest rate, number of years to pay the payments, period of repayment, and the life expectancy of the person who will receive the payments.
