A = Present Value
R = Amount of Ordinary Annuity
j = %
t = term
m = periods (annually/ semi-annually/ quarterly)
i = j/m
n = tm

A = R {[1-(1+i)-n] /i}

How do you calculate annuity payments?

An annuity is a series of equal cash flows over time that comes at regular intervals. The cash flows must be either all payments or all receipts, consistently occur either at the beginning or the end of the interval and represent one discount period. Payments made at the beginning of the period indicate an "annuity due" which can include rents and insurance payments. Payments at the end of the period indicate an "ordinary annuity" which include mortgage payments, bond payments, etc.Although loan payments, mortgages and similar financial instruments can be regarded as an annuity, the term is mostly applied from the perspective of being an asset. For example, payments from a lottery or distributions from a lump-sum amount can be considered as an annuity. Annuities can also be an investment used to guarantee a regular income during a retirement.Calculating annuity payments can come from two perspectives: the future value of an annuity or the present value of an annuity.Calculating Ordinary Annuity Payments From Future ValueIf the desired ending amount is known together with the discount rate and number of periods, the payments can be calculated as follows:PMT = FV / (((1 + r)^n - 1) / r)Where:PMT = Payment amount made at the end of the periodFV = The future value of the annuity (how much the balance will be after all payments have been made)r = the discount rate^ = raises the value to the left to an exponential number on the rightn = the number of paymentsIn this calculation, the present value (PV) is assumed to be zero.Calculating Ordinary Annuity Payments From Present ValueIf the sum of money or balance on hand is known together with the discount rate and the number of periods, the amount of payments to reduce the balance to zero can be calculated as follows:PMT = PV / ((1-[1 / (1 + r)^n] )/ r)Where:PMT = Payment amount made at the end of the periodPV = The present value of the annuity (how much is currently on hand)r = the discount rate^ = raises the value to the left to an exponential number on the rightn = the number of paymentsIn this calculation, the future value (FV) is assumed to be zero.Calculating Annuity Due Payments From Future ValueBecause the payment earns interest for one additional period than the ordinary annuity, the future value should be adjusted as follows:FV annuity due = FV ordinary annuity X (1+r)The new value for future value can now be inserted in the original equation to compute the annuity due payments.Calculating Annuity Due Payments From Present ValueTo remove the additional discount period for each payment made on an annuity due, the present value of the annuity must be adjusted as follows:PV annuity due = PV ordinary annuity X (1+r)The new value for future value can now be inserted in the original equation to compute the annuity due payments.Alternate MethodsBecause calculating the payments for ordinary annuities and annuities due, a financial calculator such as the HP 10bII can be used to simplify the process. When many calculations must be performed, the process can be expedited through the use of a spreadsheet such as Microsoft Excel which is equipped with time value of money functions.See the related links below for an annuity calculator for different types of contracts that compute the balance, distributions, or present value using the amounts you specify.

What is the difference between ordinary annuity and annuity due?

In an ordinary annuity, the payments are fed into the investment at the END of the year. In an annuity due, the payments are made at the BEGINNING of the year. Therefore, with an annuity due, each annuity payment accumulates an extra year of interest. This means that the future value of an annuity due is always greater than the future value of an ordinary annuity.When computing present value, each payment in an annuity due is discounted for one less year (because one of the payments is not made in the future- it is made at the beginning of this year and is already in terms of present dollars). This will result in a larger present value for an annuity due than for an ordinary annuity, as well.


How can you convert the present value of an ordinary annuity into the present value of annuity due?

The simplest way is to gross up the ordinary annuity (payments in arrears) by a single period at the discounting rate. For example, if the ordinary annuity has semi-annual payments (half yearly) and the PV is $1000 using a discounting rate of 5% p.a., then the PV of the annuity due would be: PVDue= $1,000 x ( 1 + 5%/2 ) = $1,025
