What Is an Annuity Table?

An annuity table is a tool for determining the present value of an annuity or other structured series of payments. Such a tool, used by accountants, actuaries, and other insurance personnel, takes into account how much money has been placed into an annuity and how long it has been there to determine how much money would be due to an annuity buyer or annuitant.

Figuring the present value of any future amount of an annuity may also be performed using a financial calculator or software built for such a purpose.

How an Annuity Table Works

An annuity table provides a factor, based on time, and a discount rate (interest rate) by which an annuity payment can be multiplied to determine its present value. For example, an annuity table could be used to calculate the present value of an annuity that paid $10,000 a year for 15 years if the interest rate is expected to be 3%.

According to the concept of the time value of money, receiving a lump sum payment in the present is worth more than receiving the same sum in the future. As such, having $10,000 today is better than being given $1,000 per year for the next 10 years because the sum could be invested and earn interest over that decade. At the end of the 10-year period, the $10,000 lump sum would be worth more than the sum of the annual payments, even if invested at the same interest rate.

Annuity Table and the Present Value of an Annuity

Present Value of an Annuity Formulas

The formula for the present value of an ordinary annuity, as opposed to an annuity due, is as follows:


$\begin{aligned}&\text{P} =\text{PMT}\times\frac{ 1 – (1 + r) ^ -n}{r}\\&\textbf{where:}\\&\text{P} = \text{Present value of an annuity stream}\\&\text{PMT} =\text{Dollar amount of each annuity payment}\\&r = \text{Interest rate (also known as the discount rate)}\\&n = \text{Number of periods in which payments will be made}\end{aligned}$​P=PMT×r1−(1+r)−n​where:P=Present value of an annuity streamPMT=Dollar amount of each annuity paymentr=Interest rate (also known as the discount rate)​

Assume an individual has an opportunity to receive an annuity that pays $50,000 per year for the next 25 years, with a discount rate of 6%, or a lump sum payment of $650,000. He needs to determine the more rational option. Using the above formula, the present value of this annuity is:


$\begin{aligned}&\text{PVA} = \$50,000 \times \frac{1 – (1 + 0.06) ^ -25}{0.06} = \$639,168\\&\textbf{where:}\\&\text{PVA}=\text{Present value of annuity}\end{aligned}$​PVA=$50,000×0.061−(1+0.06)−25​=$639,168where:​

Given this information, the annuity is worth $10,832 less on a time-adjusted basis, and the individual should choose the lump sum payment over the annuity.

Note, this formula is for an ordinary annuity where payments are made at the end of the period in question. In the above example, each $50,000 payment would occur at the end of the year, each year, for 25 years. With an annuity due, the payments are made at the beginning of the period in question. To find the value of an annuity due, simply multiply the above formula by a factor of (1 + r):


$\begin{aligned}&\text{P} = \text{PMT} \times\left(\frac{1 – (1 + r) ^ -n}{r}\right) \times (1 + r)\end{aligned}$​P=PMT×(r1−(1+r)−n​)×(1+r)​

If the above example of an annuity due, its value would be:


$\begin{aligned}&\text{P}= \$50,000\\&\quad \times\left( \frac{1 – (1 + 0.06) ^ -25}{0.06}\right)\times (1 + 0.06) = \$677,518\end{aligned}$​P=$50,000​

In this case, the individual should choose the annuity due, because it is worth $27,518 more than the lump sum payment.

Present Value of an Annuity Table

Rather than working through the formulas above, you could alternatively use an annuity table. An annuity table simplifies the math by automatically giving you a factor for the second half of the formula above. For example, the present value of an ordinary annuity table would give you one number (referred to as a factor) that is pre-calculated for the (1 – (1 + r) ^ – n) / r) portion of the formula.

The factor is determined by the interest rate (r in the formula) and the number of periods in which payments will be made (n in the formula). In an annuity table, the number of periods is commonly depicted down the left column. The interest rate is commonly depicted across the top row. Simply select the correct interest rate and number of periods to find your factor in the intersecting cell. That factor is then multiplied by the dollar amount of the annuity payment to arrive at the present value of the ordinary annuity.

Below is an example of a present value of an ordinary annuity table:

What Is Annuity Due?

An annuity due is an annuity whose payment is due immediately at the beginning of each period. A common example of an annuity due payment is rent, as landlords often require payment upon the start of a new month as opposed to collecting it after the renter has enjoyed the benefits of the apartment for an entire month.

How Annuity Due Works

An annuity due requires payments made at the beginning, as opposed to the end, of each annuity period. Annuity due payments received by an individual legally represent an asset. Meanwhile, the individual paying the annuity due has a legal debt liability requiring periodic payments.

Because a series of annuity due payments reflect a number of future cash inflows or outflows, the payer or recipient of the funds may wish to calculate the entire value of the annuity while factoring in the time value of money. One can accomplish this by using present value calculations.

A present value table for an annuity due has the projected interest rate across the top of the table and the number of periods as the left-most column. The intersecting cell between the appropriate interest rate and the number of periods represents the present value multiplier. Finding the product between one annuity due payment and the present value multiplier yields the present value of the cash flow.

A whole life annuity due is a financial product sold by insurance companies that require annuity payments at the beginning of each monthly, quarterly, or annual period, as opposed to at the end of the period. This is a type of annuity that will provide the holder with payments during the distribution period for as long as they live. After the annuitant passes on, the insurance company retains any funds remaining.

Annuity Due vs. Ordinary Annuity

An annuity due payment is a recurring issuance of money upon the beginning of a period. Alternatively, an ordinary annuity payment is a recurring issuance of money at the end of a period. Contracts and business agreements outline this payment, and it is based on when the benefit is received. When paying for an expense, the beneficiary pays an annuity due payment before receiving the benefit, while the beneficiary makes ordinary due payments after the benefit has occurred.

The timing of an annuity payment is critical based on opportunity costs. The collector of the payment may invest an annuity due payment collected at the beginning of the month to generate interest or capital gains. This is why an annuity due is more beneficial for the recipient as they have the potential to use funds faster. Alternatively, individuals paying an annuity due lose out on the opportunity to use the funds for an entire period. Those paying annuities thus tend to prefer ordinary annuities.

Examples of Annuity Due

An annuity due may arise due to any recurring obligation. Many monthly bills, such as rent, car payments, and cellphone payments, are annuities due because the beneficiary must pay at the beginning of the billing period. Insurance expenses are typically annuities due as the insurer requires payment at the start of each coverage period. Annuity due situations also typically arise relating to saving for retirement or putting money aside for a specific purpose.

How to Calculate the Value of an Annuity Due

The present and future values of an annuity due can be calculated using slight modifications to the present value and future value of an ordinary annuity.

Present Value of an Annuity Due

The present value of an annuity due tells us the current value of a series of expected annuity payments. In other words, it shows what the future total to be paid is worth now.

Calculating the present value of an annuity due is similar to calculating the present value of an ordinary annuity. However, there are subtle differences to account for when annuity payments are due. For an annuity due, payments are made at the beginning of the interval, and for an ordinary annuity, payments are made at the end of a period. The formula for the present value of an annuity due is:

With:

• C = Cash flows per period
• i = interest rate
• n = number of payments

Let’s look at an example of the present value of an annuity due. Suppose you are a beneficiary designated to immediately receive $1000 each year for 10 years, earning an annual interest rate of 3%. You want to know how much the stream of payments is worth to you today. Based on the present value formula, the present value is $8,786.11.

Future Value of an Annuity Due

The future value of an annuity due shows us the end value of a series of expected payments or the value at a future date.

Just as there are differences in how the present value is calculated for an ordinary annuity and an annuity due, there are also differences in how the future value of money is calculated for an ordinary annuity and an annuity due. The future value of an annuity due is calculated as:

Using the same example, we calculate that the future value of the stream of income payments to be $11,807.80.

Annuity Due FAQs

Which Is Better, Ordinary Annuity or Annuity Due?

Whether an ordinary annuity or an annuity due is better depends on whether you are the payee or payer. As a payee, an annuity due is often preferred because you receive payment up front for a specific term, allowing you to use the funds immediately and enjoy a higher present value than that of an ordinary annuity. As a payer, an ordinary annuity might be favorable as you make your payment at the end of the term, rather than the beginning. You are able to use those funds for the entire period before paying.

Often, you are not afforded the option to choose. For example, insurance premiums are an example of an annuity due, with premium payments due at the beginning of the covered period. A car payment is an example of an ordinary annuity, with payments due at the end of the covered period.

What Is an Immediate Annuity?

An immediate annuity is an account, funded with a lump sum deposit, that generates an immediate stream of income payments. The income can be for a stated amount (e.g., $1,000/month), a stated period (e.g., 10 years), or a lifetime.

How Do You Calculate the Future Value of an Annuity Due?

The future value of an annuity due is calculated using the formula:

where

• C = cash flows per period
• i = interest rate
• n = number of payments

What Does Annuity Mean?

An annuity is an insurance product designed to generate payments immediately or in the future to the annuity owner or a designated payee. The account holder either makes a lump sum payment or a series of payments into the annuity and can either receive an immediate stream of income or defer receiving payments until some time in the future, usually after an accumulation period where the account earns interest tax-deferred.

What Happens When an Annuity Expires?

Once an annuity expires, the contract terminates and no future payments are made. The contractual obligation is fulfilled, with no further duties owed from either party.

The Bottom Line

An annuity due is an annuity with payment due or made at the beginning of the payment interval. In contrast, an ordinary annuity generates payments at the end of the period. As a result, the method for calculating the present and future values differ. A common example of an annuity due is rent payments made to a landlord, and a common example of an ordinary annuity includes mortgage payments made to a lender. Depending on whether you are the payer or payee, the annuity due might be a better option.
