A mortgage is the payment of money to a person or company on the future sale of a current property. The future sale of the property is called an annuity. An annuity is a legal promise to pay a particular amount of money at some future date for a stated amount of time. These promises are legally binding once made. For this reason, an annuity can be very useful to a person who may need funds in the future.

Annuity calculators are financial tools that help in determining the value of different annuities. The first step that you should do in order to obtain a good annuity calculator is to understand the different types of annuities. Fixed annuities pay fixed monthly payments throughout the entire life of the annuity.

Discounted annuities pay lump sum amounts to the beneficiary in case of death or disablement. Premium based annuities and unit-linked annuities are other types of annuities. The most commonly used discount rate in present value calculation method is the annuity discount rate or AICCR. This is the discount rate used in the calculation of the present value of an annuity.

Present value of a discounted annuity is a ratio of the amount invested to the amount expected to be earned. A good annuity calculator helps to determine this ratio. In this method, a person needs to provide the amount of cash he or she would like to receive upon retirement. Then, a certain amount of cash is invested at a certain rate. After a specified number of years, the retiree is required to receive a specific amount.

When using annuities calculator, you will need to know the number of years of service needed in order to receive a certain amount of money after retirement. You can also select a mode of compensation. Some people prefer to receive lump sum money upon retirement. The amount of money to be given depends on the type of annuity chosen. If you want a lump sum with immediate payment, you should select the deferred annuity. However, if you want a deferred payment that becomes available in subsequent 3 years, you should select the indexed annuity mode.

Annuity formula uses the value of the annuity principle minus the discount rate in order to determine the amount to give at retirement. If there are no guaranteed future payments, the payout amount will be equal to the current market value on the date of retirement. On the other hand, if the market price increases over the period of time until the actual retirement date, the value of the settlement sum will decrease. Therefore, the actual value of the annuity will increase over time. The lifetime payout amount will also increase depending on the discount rate.
