OnlyTheBestChoice – An annuity is an insurance contract in the form of an investment, and provides a source of income in the form of periodic payments during the agreed period for the recipient of an annuity (annuity) or heir, starting now or at a future time. This investment can be a great addition to a retirement portfolio, but it is quite confusing indeed. Understand how annuities and income are likely to work to help plan for the future and tailor your other investments. The steps below will show you how to calculate annuity payments and accurately estimate future income.
- Determine the Type of Annuity You Have:
Specify your annuity payment type. Check your documents or contact the annuity issuing company to see if your payment is immediate or deferred. If it is of an immediate nature, an annuity payment will begin immediately after the initial investment. If you have a deferred annuity, investment payments will accumulate regular interest rates. 
A. Determine the type of investment from your annuity. your investment may be of a fixed or variable type. You can also check the type of investment by viewing documents or contacting an annuity issuing company. Annuities still have guaranteed interest rates, and therefore payments are also guaranteed. Variable annuities rely heavily on the underlying investment kineja, and therefore the amount of payment differs each month. You choose the type of investment when you buy an annuity. This annuity is the object of PPh 21.  
B. Know your liquidity options. Check your annuity contract or contact the annuity issuing company for liquidity options for your annuity. You may be penalized if you withdraw your funds early. Some annuities with this penalty allow partial withdrawal of funds without penalty. There are also annuities that do not award a penalty, such as a no-surrender annuity or load level. 
- Determine the Details of Your Annuity.
A. Find out your annuity payment options. The most popular payment option is the payment of the full amount of an annuity during the agreed period, with all remaining balances after your death given to your heir. Other options include payment to death in the absence of an heir, or payment over a certain period including payment to the heir after the death of annuity for a certain period of time. There is also an annuity option that pays the heir for the duration of his or her age that exceeds yours. 
B. Find your principal balance. Your principal balance is the amount paid to buy an annuity either in the form of an initial payment or a monthly installment (e.g. from a salary).  If payments are made regularly, you should ask for the current balance amount to calculate your payment.
You will also receive an annuity statement report. Your balance should be included in this report.
c. Find the interest rate. Perhaps, there is a minimum guaranteed interest rate that you earn when buying an annuity. This means that your interest rate will never fall below that rate.  Otherwise, the fixed rate must be included in the documents received when purchasing the annuity, or if the annuity is variable, you can find out the guaranteed interest rate by contacting the annuity issuing company or checking your account online.
The annuity statement report should also include your interest rate.
- Calculate Your Payment
A. Calculate the payment amount based on your specific situation. For example, assume an annuity price of Rp65,000,000,000 with a 4% interest rate that will pay a fixed amount annually for the next 25 years. Annuity Value Formula = Sum of Payments x Present Value of an Annuity (PVOA).  PVOA tables are available here.
- PvOA factor for the above scenario is 15.62208. Therefore, 65,000,000,000 = Annual payment x 15.62208. As a result, an annual payment amounted to Rp32,005,980.
- You can also calculate the payment amount using the “PMT” function in Excel. The syntax is “=PMT(Interest Rate,Number ofPeriodes,Current Value,ValueComing).” Based on the example above, type “=PMT(0,04,25,6500000000,0)” in the cell and press “Enter.” There should be no spaces in this function. The result is £1,999.
B. Adjust the calculation if the annuity will not be paid in a few years. Find the future value of your current principal balance using the Future Value table, the interest rate that will increase on your annuity between now and the payment starts to be awarded, and the number of years until you start withdrawing payments. For example, assume your £65,000 will receive 2% annual interest until it starts paying for 20 years. Multiply Rp65,000,000,000 by 1.48595 (known from the Future Values table) and get a result of 742,975. Future values are generated using mathematical equations. You can see the table here.
- Find upcoming values using FV function in Excel. The syntax is “=FV(Flower Tribe,Number ofPeriodes,AdditionalPayments,Current Value).” Enter “0” for additional payment variables.
- Replace future values with annuity balances and recalculate payments using the formula “Annuity Value = Payment Amount x PVOA factor”. Based on these variables, your annual payment is $4,559,290.
You can also adjust your annual payments to a more frequent frequency. To calculate a monthly payment, divide the interest rate by 12 and multiply the period by 12 before entering the numbers into the formula.
Financial consultants agree that one should not rely on a single source of income to support retirement. Diversification (dissemination of sources of income) is essential in all investment portfolios. [red/*]
