What Is the Aroon Indicator?

The Aroon indicator is a technical indicator that is used to identify trend changes in the price of an asset, as well as the strength of that trend. In essence, the indicator measures the time between highs and the time between lows over a time period. The idea is that strong uptrends will regularly see new highs, and strong downtrends will regularly see new lows. The indicator signals when this is happening, and when it isn’t.

The indicator consists of the “Aroon up” line, which measures the strength of the uptrend, and the “Aroon down” line, which measures the strength of the downtrend.

The Aroon indicator was developed by Tushar Chande in 1995.

Formulas for the Aroon Indicator


$\begin{aligned} \text{Aroon Up}&= \frac{25-\text{Periods Since 25 period High}}{25} \ast100\\ \text{Aroon Down}&=\frac{25-\text{Periods Since 25 period Low}}{25}\ast100 \end{aligned}$Aroon UpAroon Down​=2525−Periods Since 25 period High​∗100=2525−Periods Since 25 period Low​∗100​

How to Calculate the Aroon Indicator

The Aroon calculation requires the tracking of the high and low prices, typically over 25 periods.

1. Track the highs and lows for the last 25 periods on an asset.
2. Note the number of periods since the last high and low.
3. Plug these numbers into the Up and Down Aroon formulas.

What Does the Aroon Indicator Tell You?

The Aroon Up and the Aroon Down lines fluctuate between zero and 100, with values close to 100 indicating a strong trend and values near zero indicating a weak trend. The lower the Aroon Up, the weaker the uptrend and the stronger the downtrend, and vice versa. The main assumption underlying this indicator is that a stock’s price will close regularly at new highs during an uptrend, and regularly make new lows in a downtrend.

The indicator focuses on the last 25 periods, but is scaled to zero and 100. Therefore, an Aroon Up reading above 50 means the price made a new high within the last 12.5 periods. A reading near 100 means a high was seen very recently. The same concepts apply to the Down Aroon. When it is above 50, a low was witnessed within the 12.5 periods. A Down reading near 100 means a low was seen very recently.

Crossovers can signal entry or exit points. Up crossing above Down can be a signal to buy. Down crossing below Up may be a signal to sell.

When both indicators are below 50 it can signal that the price is consolidating. New highs or lows are not being created. Traders can watch for breakouts as well as the next Aroon crossover to signal which direction price is going.

Example of How to Use the Aroon Indicator

The following chart shows an example of the Aroon indicator and how it can be interpreted.

In the chart above, there is both the Aroon indicator and an oscillator that combines both lines into a single reading of between 100 and -100. The crossover of the Aroon Up and Aroon Down indicated a reversal in the trend. While the index was trending, prior to the reversal, the Aroon Down remained very low, suggesting that the index had a bullish bias. Despite the rally on the far right, the Aroon indicator hasn’t shown a bullish bias yet. This is because the price rebounded so quickly that it hasn’t made a new high in the last 25 periods (at the time of the screenshot), despite the rally.

The Difference Between the Aroon Indicator and the Directional Movement Index (DMI)

The Aroon indicator is similar to the Directional Movement Index (DMI) developed by Welles Wilder. It too uses up and down lines to show the direction of a trend. The main difference is that the Aroon indicator formulas are primarily focused on the amount of time between highs and lows. The DMI measures the price difference between current highs/lows and prior highs/lows. Therefore, the main factor in the DMI is price, and not time.

Limitations of Using the Aroon Indicator

The Aroon indicator may at times signal a good entry or exit, but other times it will provide poor or false signals. The buy or sell signal may occur too late, after a substantial price move has already occurred. This happens because the indicator is looking backwards, and isn’t predictive in nature.

A crossover may look good on the indicator, but that doesn’t mean the price will necessarily make a big move. The indicator isn’t factoring the size of moves, it only cares about the number of days since a high or low. Even if the price is relatively flat, crossovers will occur as eventually a new high or low will be made within the last 25 periods. Traders still need to use price analysis, and potentially other indicators, to make informed trading decisions. Relying solely on one indicator isn’t advised.

What Is the Accounting Rate of Return (ARR)?

The accounting rate of return (ARR) is a formula that reflects the percentage rate of return expected on an investment or asset, compared to the initial investment’s cost. The ARR formula divides an asset’s average revenue by the company’s initial investment to derive the ratio or return that one may expect over the lifetime of an asset or project. ARR does not consider the time value of money or cash flows, which can be an integral part of maintaining a business.

Understanding the Accounting Rate of Return (ARR)

The accounting rate of return is a capital budgeting metric that’s useful if you want to calculate an investment’s profitability quickly. Businesses use ARR primarily to compare multiple projects to determine the expected rate of return of each project, or to help decide on an investment or an acquisition.

ARR factors in any possible annual expenses, including depreciation, associated with the project. Depreciation is a helpful accounting convention whereby the cost of a fixed asset is spread out, or expensed, annually during the useful life of the asset. This lets the company earn a profit from the asset right away, even in its first year of service.

The Formula for ARR

The formula for the accounting rate of return is as follows:

$ARR = \frac{Average\, Annual\, Profit}{Initial\, Investment}$ARR=InitialInvestmentAverageAnnualProfit​

How to Calculate the Accounting Rate of Return (ARR)

1. Calculate the annual net profit from the investment, which could include revenue minus any annual costs or expenses of implementing the project or investment.
2. If the investment is a fixed asset such as property, plant, and equipment (PP&E), subtract any depreciation expense from the annual revenue to achieve the annual net profit.
3. Divide the annual net profit by the initial cost of the asset or investment. The result of the calculation will yield a decimal. Multiply the result by 100 to show the percentage return as a whole number.

Example of the Accounting Rate of Return (ARR)

As an example, a business is considering a project that has an initial investment of $250,000 and forecasts that it would generate revenue for the next five years. Here’s how the company could calculate the ARR:

• Initial investment: $250,000
• Expected revenue per year: $70,000
• Time frame: 5 years
• ARR calculation: $70,000 (annual revenue) / $250,000 (initial cost)
• ARR = 0.28 or 28%

Accounting Rate of Return vs. Required Rate of Return

The ARR is the annual percentage return from an investment based on its initial outlay of cash. Another accounting tool, the required rate of return (RRR), also known as the hurdle rate, is the minimum return an investor would accept for an investment or project that compensates them for a given level of risk.

The RRR can vary between investors as they each have a different tolerance for risk. For example, a risk-averse investor likely would require a higher rate of return to compensate for any risk from the investment. It’s important to utilize multiple financial metrics including ARR and RRR to determine if an investment would be worthwhile based on your level of risk tolerance.

Advantages and Disadvantages of the Accounting Rate of Return (ARR)

Advantages

The accounting rate of return is a simple calculation that does not require complex math and is helpful in determining a project’s annual percentage rate of return. Through this, it allows managers to easily compare ARR to the minimum required return. For example, if the minimum required return of a project is 12% and ARR is 9%, a manager will know not to proceed with the project.

ARR comes in handy when investors or managers need to quickly compare the return of a project without needing to consider the time frame or payment schedule but rather just the profitability or lack thereof.

Disadvantages

Despite its advantages, ARR has its limitations. It doesn’t consider the time value of money. The time value of money is the concept that money available at the present time is worth more than an identical sum in the future because of its potential earning capacity.

In other words, two investments might yield uneven annual revenue streams. If one project returns more revenue in the early years and the other project returns revenue in the later years, ARR does not assign a higher value to the project that returns profits sooner, which could be reinvested to earn more money.

The accounting rate of return does not consider the increased risk of long-term projects and the increased uncertainty associated with long periods.

Also, ARR does not take into account the impact of cash flow timing. Let’s say an investor is considering a five-year investment with an initial cash outlay of $50,000, but the investment doesn’t yield any revenue until the fourth and fifth years.

In this case, the ARR calculation would not factor in the lack of cash flow in the first three years, while in reality, the investor would need to be able to withstand the first three years without any positive cash flow from the project.

The Bottom Line

The accounting rate of return (ARR) is a simple formula that allows investors and managers to determine the profitability of an asset or project. Because of its ease of use and determination of profitability, it is a handy tool in making decisions. However, the formula does not take into consideration the cash flows of an investment or project, the overall timeline of return, and other costs, which help determine the true value of an investment or project.

What Is Annual Percentage Rate (APR)?

Annual percentage rate (APR) refers to the yearly interest generated by a sum that’s charged to borrowers or paid to investors. APR is expressed as a percentage that represents the actual yearly cost of funds over the term of a loan or income earned on an investment. This includes any fees or additional costs associated with the transaction but does not take compounding into account. The APR provides consumers with a bottom-line number they can compare among lenders, credit cards, or investment products.

How the Annual Percentage Rate (APR) Works

An annual percentage rate is expressed as an interest rate. It calculates what percentage of the principal you’ll pay each year by taking things such as monthly payments and fees into account. APR is also the annual rate of interest paid on investments without accounting for the compounding of interest within that year.

The Truth in Lending Act (TILA) of 1968 mandates that lenders disclose the APR they charge to borrowers. Credit card companies are allowed to advertise interest rates on a monthly basis, but they must clearly report the APR to customers before they sign an agreement.

How Is APR Calculated?

APR is calculated by multiplying the periodic interest rate by the number of periods in a year in which it was applied. It does not indicate how many times the rate is actually applied to the balance.

$\begin{aligned} &\text{APR} = \left ( \left ( \frac{ \frac{ \text{Fees} + \text{Interest} }{ \text {Principal} } }{ n } \right ) \times 365 \right ) \times 100 \\ &\textbf{where:} \\ &\text{Interest} = \text{Total interest paid over life of the loan} \\ &\text{Principal} = \text{Loan amount} \\ &n = \text{Number of days in loan term} \\ \end{aligned}$​APR=((nPrincipalFees+Interest​​)×365)×100where:Interest=Total interest paid over life of the loanPrincipal=Loan amountn=Number of days in loan term​

Types of APRs

Credit card APRs vary based on the type of charge. The credit card issuer may charge one APR for purchases, another for cash advances, and yet another for balance transfers from another card. Issuers also charge high-rate penalty APRs to customers for late payments or violating other terms of the cardholder agreement. There’s also the introductory APR—a low or 0% rate—with which many credit card companies try to entice new customers to sign up for a card.

Bank loans generally come with either fixed or variable APRs. A fixed APR loan has an interest rate that is guaranteed not to change during the life of the loan or credit facility. A variable APR loan has an interest rate that may change at any time.

The APR borrowers are charged also depends on their credit. The rates offered to those with excellent credit are significantly lower than those offered to those with bad credit.

APR vs. Annual Percentage Yield (APY)

Though an APR only accounts for simple interest, the annual percentage yield (APY) takes compound interest into account. As a result, a loan’s APY is higher than its APR. The higher the interest rate—and to a lesser extent, the smaller the compounding periods—the greater the difference between the APR and APY.

Imagine that a loan’s APR is 12%, and the loan compounds once a month. If an individual borrows $10,000, their interest for one month is 1% of the balance, or $100. That effectively increases the balance to $10,100. The following month, 1% interest is assessed on this amount, and the interest payment is $101, slightly higher than it was the previous month. If you carry that balance for the year, your effective interest rate becomes 12.68%. APY includes these small shifts in interest expenses due to compounding, while APR does not.

Here’s another way to look at it. Say you compare an investment that pays 5% per year with one that pays 5% monthly. For the first month, the APY equals 5%, the same as the APR. But for the second, the APY is 5.12%, reflecting the monthly compounding.

Given that an APR and a different APY can represent the same interest rate on a loan or financial product, lenders often emphasize the more flattering number, which is why the Truth in Savings Act of 1991 mandated both APR and APY disclosure in ads, contracts, and agreements. A bank will advertise a savings account’s APY in a large font and its corresponding APR in a smaller one, given that the former features a superficially larger number. The opposite happens when the bank acts as the lender and tries to convince its borrowers that it’s charging a low rate. A great resource for comparing both APR and APY rates on a mortgage is a mortgage calculator.

APR vs. APY Example

Let’s say that XYZ Corp. offers a credit card that levies interest of 0.06273% daily. Multiply that by 365, and that’s 22.9% per year, which is the advertised APR. Now, if you were to charge a different $1,000 item to your card every day and waited until the day after the due date (when the issuer started levying interest) to start making payments, you’d owe $1,000.6273 for each thing you bought.

To calculate the APY or effective annual interest rate—the more typical term for credit cards—add one (that represents the principal) and take that number to the power of the number of compounding periods in a year; subtract one from the result to get the percentage:

$\begin{aligned} &\text{APY} = (1 + \text{Periodic Rate} ) ^ n – 1 \\ &\textbf{where:} \\ &n = \text{Number of compounding periods per year} \\ \end{aligned}$​APY=(1+Periodic Rate)n−1where:n=Number of compounding periods per year​

In this case your APY or EAR would be 25.7%:

$\begin{aligned} &( ( 1 + .0006273 ) ^ {365} ) – 1 = .257 \\ \end{aligned}$​((1+.0006273)365)−1=.257​

If you only carry a balance on your credit card for one month’s period, you will be charged the equivalent yearly rate of 22.9%. However, if you carry that balance for the year, your effective interest rate becomes 25.7% as a result of compounding each day.

APR vs. Nominal Interest Rate vs. Daily Periodic Rate

An APR tends to be higher than a loan’s nominal interest rate. That’s because the nominal interest rate doesn’t account for any other expense accrued by the borrower. The nominal rate may be lower on your mortgage if you don’t account for closing costs, insurance, and origination fees. If you end up rolling these into your mortgage, your mortgage balance increases, as does your APR.

The daily periodic rate, on the other hand, is the interest charged on a loan’s balance on a daily basis—the APR divided by 365. Lenders and credit card providers are allowed to represent APR on a monthly basis, though, as long as the full 12-month APR is listed somewhere before the agreement is signed.

Disadvantages of Annual Percentage Rate (APR)

The APR isn’t always an accurate reflection of the total cost of borrowing. In fact, it may understate the actual cost of a loan. That’s because the calculations assume long-term repayment schedules. The costs and fees are spread too thin with APR calculations for loans that are repaid faster or have shorter repayment periods. For instance, the average annual impact of mortgage closing costs is much smaller when those costs are assumed to have been spread over 30 years instead of seven to 10 years.

APR also runs into some trouble with adjustable-rate mortgages (ARMs). Estimates always assume a constant rate of interest, and even though APR takes rate caps into consideration, the final number is still based on fixed rates. Because the interest rate on an ARM will change when the fixed-rate period is over, APR estimates can severely understate the actual borrowing costs if mortgage rates rise in the future.

Mortgage APRs may or may not include other charges, such as appraisals, titles, credit reports, applications, life insurance, attorneys and notaries, and document preparation. There are other fees that are deliberately excluded, including late fees and other one-time fees.

All this may make it difficult to compare similar products because the fees included or excluded differ from institution to institution. In order to accurately compare multiple offers, a potential borrower must determine which of these fees are included and, to be thorough, calculate APR using the nominal interest rate and other cost information.

The Bottom Line

The APR is the basic theoretical cost or benefit of money loaned or borrowed. By calculating only the simple interest without periodic compounding, the APR gives borrowers and lenders a snapshot of how much interest they are earning or paying within a certain period of time. If someone is borrowing money, such as by using a credit card or applying for a mortgage, the APR can be misleading because it only presents the base number of what they are paying without taking time into the equation. Conversely, if someone is looking at the APR on a savings account, it doesn’t illustrate the full impact of interest earned over time.

APRs are often a selling point for different financial instruments, such as mortgages or credit cards. When choosing a tool with an APR, be careful to also take into account the APY because it will prove a more accurate number for what you will pay or earn over time. Though the formula for your APR may stay the same, different financial institutions will include different fees in the principal balance. Be aware of what is included in your APR when signing any agreement.

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.
