| | |
| In some areas, the ''annual percentage rate'' (APR) is the simplified counterpart to the [[effective interest rate]] that the borrower will pay on a loan. In many countries and jurisdictions, lenders (such as banks) are required to disclose the "cost" of borrowing in some standardized way as a form of [[consumer protection]]. APR is intended to make it easier to compare lenders and loan options.
| |
| | |
| ==Multiple definitions of effective APR==
| |
| | |
| The nominal APR is calculated as: the rate, for a payment period, multiplied by the number of payment periods in a year.<ref name=USfed/> However, the exact legal definition of "effective APR", or EAR, can vary greatly in each jurisdiction, depending on the type of fees included, such as participation fees, [[loan origination]] fees, monthly [[service charge]]s, or [[late fee]]s. The effective APR has been called the "mathematically-true" interest rate for each year.<ref name="USNapr">

| | |
| The computation for the effective APR, as the fee+[[compound interest]] rate, can also vary depending on whether the up-front fees, such as origination or participation fees, are added to the entire amount, or treated as a short-term loan due in the first payment. When start-up fees are paid as first payment(s), the balance due might accrue more interest, as being delayed by the extra payment period(s).<ref name="Marg">

| |
| | |
| There are at least three ways of computing effective annual percentage rate:
| |
| * by compounding the interest rate for each year, without considering fees;
| |
| * origination fees are added to the balance due, and the total amount is treated as the basis for computing compound interest;
| |
| * the [[origination fee]]s are [[amortization|amortized]] as a short-term loan. This loan is due in the first payment(s), and the unpaid balance is amortized as a second long-term loan. The extra first payment(s) is dedicated to primarily paying origination fees and interest charges on that portion.
| |
| | |
| For example, consider a $100 loan which must be repaid after one month, plus 5%, plus a $10 fee. If the fee is not considered, this loan has an effective APR of approximately 80% (<math>1.05^{12} = 1.7959</math>, which is approximately an 80% increase). If the $10 fee were considered, the monthly interest increases by 10% ($10/$100), and the effective APR becomes approximately 435% (<math>1.15^{12} = 5.3503</math>, which equals a 435% increase). Hence there are at least two possible "effective APRs": 80% and 435%. Laws vary as to whether fees must be included in APR calculations.
| |
| | |
| ===United States===
| |
| In the U.S., the calculation and disclosure of APR is governed by the [[Truth in Lending Act]] (which is implemented by the CFPB in [http://www.fdic.gov/regulations/laws/rules/6500-1400.html Regulation Z]). In general, APR in the United States is expressed as the periodic interest rate times the number of compounding periods in a year<ref>http://www.uncdf.org/mfdl/readings/EIR_Tucker.pdf Tucker, William R. "Effective Interest Rate," Paper, Bankakademie Micro Banking Competence Center, 5–6 September 2000.</ref> (also known as the [[nominal interest rate]]); since the APR must include certain non-interest charges and fees, it requires more detailed calculation. The APR must be disclosed to the borrower within 3 days of applying for a mortgage. This information is typically mailed to the borrower and the APR is found on the truth in lending disclosure statement, which also includes an amortization schedule.
| |
| | |
| On July 30, 2009, provisions of the Mortgage Disclosure Improvement Act of 2008 (MDIA) came into effect. A specific clause of this act refers directly to APR disclosure on mortgages. It states, if the final annual percentage rate APR is off by more than .125% from the initial [[good faith estimate|GFE]] disclosure, then the lender must re-disclose and wait yet another three business days before closing on the transaction.

| | |
| === European Union ===
| |
| In the EU, the focus of APR standardization is heavily on transparency and consumer rights: «a comprehensible set of information to be given to consumers in good time before the contract is concluded and also as part of the credit agreement [...] every creditor has to use this form when marketing a consumer credit in any Member State» so marketing different figures is not allowed.
| |
| | |
| The EU regulations were reinforced with directives 2008/48/EC and 2011/90/EU, fully in force in all member states since 2013.<ref>http://ec.europa.eu/consumers/rights/fin_serv_en.htm#credit</ref>
| |
| However in the UK the EU directive has been interpreted as the [[Representative APR]].
| |
| | |
| A single method of calculating the APR was introduced in directive 98/7/EC and is required to be published for the major part of loans. The basic equation for calculation of APR in the EU is:
| |
| :: <math>\sum_{l=1}^M S_l (1 + \mathrm{APR}/100)^{-t_l} = \sum_{k=1}^N A_k (1 + \mathrm{APR}/100)^{-t_k}</math>
| |
| :where:
| |
| :: <math>M</math> is the number of cash flows paid by the lender
| |
| :: <math>l</math> is the sequence number for the cash flows paid by the lender (draw down)
| |
| :: <math>S_l</math> is the cash flow (drawdown) in period <math>l</math>
| |
| :: <math>N</math> is the total number of cash flows paid by the borrower
| |
| :: <math>k</math> is the sequence number of the cash flows paid by the borrower (repayment)
| |
| :: <math>A_k</math> is the cash flow (repayment) of period <math>k</math>, and
| |
| :: <math>t_l</math> and <math>t_k</math> is the interval, expressed in years and fractions of a year between the date of the first cash flow and the date of cash flow <math>l</math> or <math>k</math>. (<math>t_1</math> = 0.)
| |
| In this equation the left side is the [[present value]] of the draw downs made by the lender and the right side is the [[present value]] of the repayments made by the borrower. In both cases the [[present value]] is defined given the APR as the interest rate. So the [[present value]] of the drawdowns is equal to the [[present value]] of the repayments, given the APR as the interest rate. | |
| | |
| Note that neither the amounts nor the periods between transactions are necessarily equal. For the purposes of this calculation, a year is presumed to have 365 days (366 days for leap years), 52 weeks or 12 equal months. As per the standard: "An equal month is presumed to have 30.41666 days (i.e. 365/12) regardless of whether or not it is a leap year." The result is to be expressed to at least one decimal place. This algorithm for APR is required for some but not all forms of consumer debt in the EU. For example, this EU directive is limited to agreements of €50,000 and below and excludes all mortgages.[http://ec.europa.eu/consumers/cons_int/fina_serv/cons_directive/2ndproposal_en.pdf]
| |
| | |
| In the Netherlands the formula above is also used for mortgages. In many cases the mortgage is not always paid back completely at the end of period <math>N</math>, but for instance when the borrower sells his house or dies. In addition, there is usually only one payment of the lender to the borrower: in the beginning of the loan. In that case the formula becomes:
| |
| :: <math>S -A = R (1 + \mathrm{APR}/100)^{-t_N} + \sum_{k=1}^N A_k (1 + \mathrm{APR}/100)^{-t_k}</math>
| |
| :where:
| |
| :: <math>S</math> is the borrowed amount
| |
| :: <math>A</math> is the prepaid onetime fee
| |
| :: <math>R</math> the rest debt, the amount that remains as an interest-only loan after the last cash flow.
| |
| | |
| If the length of the periods are equal (monthly payments) then the summations can be simplified using the formula for a [[geometric series]]. Either way, the APR can be solved iteratively only from the formulas above, apart from trivial cases such as <math>N=1</math>
| |
| | |
| ===Additional considerations===
| |
| * Confusion is possible in that if the word "effective" is used separately as meaning "influential" or having a "long-range effect", then the term ''effective APR'' will vary, as it is not a strict legal definition in some countries. The APR is used to find compound and simple interest rates.
| |
| | |
| * APR is also an abbreviation for "Annual Principal Rate" which is sometimes used in the auto sales in some countries where the interest is calculated based on the "Original Principal" not the "Current Principal Due", so as the Current Principal Due decreases, the interest due does not.
| |
| | |
| ==Rate format==
| |
| {{Unreferenced section|date=November 2008}}
| |
| An [[effective annual interest rate]] of 10% can also be expressed in several ways:
| |
| * 0.7974% effective monthly interest rate, because 1.007974<sup>12</sup>=1.1
| |
| * 9.569% annual interest rate compounded monthly, because 12×0.7974=9.569
| |
| * 9.091% annual rate in advance, because (1.1-1)÷1.1=0.091
| |
| | |
| These rates are all equivalent, but to a consumer who is not trained in the [[mathematics of finance]], this can be confusing. APR helps to standardize how interest rates are compared, so that a 10% loan is not made to look cheaper by calling it a loan at "9.1% annually in advance".
| |
| | |
| The APR does not necessarily convey the total amount of interest paid over the course of a year: if one pays part of the interest prior to the end of the year, the total amount of interest paid is less.
| |
| | |
| In the case of a loan with no fees, the [[amortization schedule]] would be worked out by taking the principal left at the end of each month, multiplying by the monthly rate and then subtracting the monthly payment. This can be expressed mathematically by
| |
| | |
| <math> p = \frac{P_0\cdot r\cdot (1+r)^n}{(1+r)^n-1} </math>
| |
| :where:
| |
| :: <math> P_0 </math> is the initial principal
| |
| :: <math> r </math> is the percentage rate used each payment
| |
| :: <math> n </math> is the number of payments
| |
| | |
| This also explains why a 15 year mortgage and a 30 year mortgage with the same APR would have different monthly payments and a different total amount of interest paid. There are many more periods over which to spread the principal, which makes the payment smaller, but there are just as many periods over which to charge interest at the same rate, which makes the total amount of interest paid much greater. For example, $100,000 mortgaged (without fees, since they add into the calculation in a different way) over 15 years costs a total of $193,429.80 (interest is 93.430% of principal), but over 30 years, costs a total of $315,925.20 (interest is 215.925% of principal).
| |
| | |
| In addition the APR takes costs into account. Suppose for instance that $100,000 is borrowed with $1000 one-time fees paid in advance. If, in the second case, equal monthly payments are made of $946.01 against 9.569% compounded monthly then it takes 240 months to pay the loan back. If the $1000 one-time fees are taken into account then the yearly interest rate paid is effectively equal to 10.31%.
| |
| | |
| The APR concept can also be applied to savings accounts: imagine a savings account with 1% costs at each withdrawal and again 9.569% interest compounded monthly. Suppose that the complete amount including the interest is withdrawn after exactly one year. Then, taking this 1% fee into account, the savings effectively earned 8.9% interest that year.
| |
| | |
| === Money factor ===
| |
| <!-- This is a crude merge from [[Money factor]]. Cleanup of any kind would appreciated. --> | |
| The APR can also be represented by a '''money factor''' (also known as the [[lease]] factor, lease rate, or factor). The money factor is usually given as a decimal, for example {{ttt|.0030}}. To find the equivalent APR, the money factor is multiplied by 2400. A money factor of .0030 is equivalent to a monthly interest rate of 0.6% and an APR of 7.2%.<ref>{{cite web | |

| | |
| Despite repeated attempts by regulators to establish usable and consistent standards, APR does not represent the total cost of borrowing in some jurisdictions nor does it really create a comparable standard across jurisdictions. Nevertheless, it is considered a reasonable starting point for an ''ad hoc'' comparison of lenders.
| |
| | |
| === Nominal APR does not reflect the true cost ===
| |
| | |
| Credit card holders should be aware that most U.S. credit cards are quoted in terms of nominal APR compounded monthly, which is not the same as the effective annual rate (EAR). Despite the “Annual” in APR, it is not necessarily a direct reference for the interest rate paid on a stable balance over one year. The more direct reference for the one-year rate of interest is EAR.
| |
| The general conversion factor for APR to EAR is
| |
| <math> \mathrm{EAR} = (1 + \tfrac{\mathrm{APR}}{n})^n - 1 </math>,
| |
| where ''n'' represents the number of compounding periods of the APR per EAR period.
| |
| As an example, for a common credit card quoted at 12.99% APR compounded monthly, the one year EAR is
| |
| <math> (1+\tfrac{0.129949}{12})^{12} - 1 </math>, | |
| or 13.7975%.
| |
| For 12.99% APR compounded daily, the EAR paid on a stable balance over one year becomes 13.87% (see [[credit card interest]] for the .000049 addition to the 12.99% APR). Note that a high U.S. APR of 29.99% compounded monthly carries an effective annual rate of 34.48%.
| |
| | |
| While the difference between APR and EAR may seem trivial, because of the exponential nature of interest these small differences can have a large effect over the life of a loan. For example, consider a 30-year loan of $200,000 with a stated APR of 10.00%, i.e., 10.0049% APR or the EAR equivalent of 10.4767%. The monthly payments, using APR, would be $1755.87. However, using an EAR of 10.00% the monthly payment would be $1691.78. The difference between the EAR and APR amounts to a difference of $64.09 per month. Over the life of a 30-year loan, this amounts to $23,070.86, which is over 11% of the original loan amount.
| |
| | |
| === Certain fees are not considered ===
| |
| Some classes of fees are deliberately not included in the calculation of APR. Because these fees are not included, some consumer advocates claim that the APR does not represent the ''total'' cost of borrowing. Excluded fees may include:
| |
| * routine one-time fees which are paid to someone other than the lender (such as a real estate attorney's fee)
| |
| * penalties such as late fees or service reinstatement fees without regard for the size of the penalty or the likelihood that it will be imposed.
| |
| | |
| Lenders argue that the real estate attorney's fee, for example, is a pass-through cost, not a cost of the lending. In effect, they are arguing that the attorney's fee is a separate transaction and not a part of the loan. Consumer advocates argue that this would be true if the customer is free to select which attorney is used. If the lender insists on using a specific attorney however, then the cost should be looked at as a component of the total cost of doing business with that lender. This area is made more complicated by the practice of contingency fees – for example, when the lender receives money from the attorney and other agents to be the one used by the lender. Because of this, U.S. regulators require all lenders to produce an affiliated business disclosure form which shows the amounts paid between the lender and the appraisal firms, attorneys, etc.
| |
| | |
| Lenders argue that including late fees and other conditional charges would require them to make assumptions about the consumer's behavior – assumptions which would bias the resulting calculation and create more confusion than clarity.
| |
| | |
| ===Not a comparable standard===
| |
| Even beyond the non-included cost components listed above, regulators have been unable to completely define which one-time fees must be included and which excluded from the calculation. This leaves the lender with some discretion to determine which fees will be included (or not) in the calculation.
| |
| | |
| Consumers can, of course, use the [[nominal interest rate]] and any costs on the loan (or savings account) and compute the APR themselves, for instance using one of the calculators on the internet.
| |
| | |
| In the example of a [[mortgage loan]], the following kinds of fees are:
| |
| {| class="wikitable"
| |
| |-
| |
| | width=50% valign=top|
| |
| '''Generally included:'''
| |
| * [[Point in a mortgage|Points]]
| |
| * Pre-paid interest
| |
| * [[Origination fee]]s including loan processing, underwriting and document preparation
| |
| * Attorney and notary fees

| * Closing agent's document preparation fees
| |
| * [[Lenders mortgage insurance|Private mortgage insurance]] (PMI)

| |
| * [[Real estate appraisal|Appraisal]]
| |
| * Home-inspection
| |
| * [[Credit report]] costs
| |
| * Title fee
| |
| *
| |
| |}
| |
| The discretion that is illustrated in the "sometimes included" column even in the highly regulated U.S. home mortgage environment makes it difficult to simply compare the APRs of two lenders. Note: U.S. regulators generally require a lender to use the same assumptions and definitions in their calculation of APR for each of their products even though they cannot force consistency across lenders.
| |
| | |
| With respect to items that may be sold with vendor financing, for example, automobile leasing, the notional cost of the good may effectively be hidden and the APR subsequently rendered meaningless. An example is a case where an automobile is leased to a customer based on a "manufacturer's suggested retail price" with a low APR: the vendor may be accepting a lower lease rate as a trade-off against a higher sale price. Had the customer self-financed, a discounted sales price may have been accepted by the vendor; in other words, the customer has received cheap financing in exchange for paying a higher purchase price, and the quoted APR understates the true cost of the financing. In this case, the only meaningful way to establish the "true" APR would involve arranging financing through other sources, determining the lowest-acceptable cash price and comparing the financing terms (which may not be feasible in all circumstances). For leases where the lessee has a purchase option at the end of the lease term, the cost of the APR is further complicated by this option. In effect, the lease includes a [[put option]] back to the manufacturer (or, alternatively, a call option for the consumer), and the value (or cost) of this option to the consumer is not transparent.
| |
| | |
| ===Dependence on loan period===
| |
| APR is dependent on the time period for which the loan is calculated. That is, the APR for one loan with a 30 year loan duration cannot be compared to the APR for another loan with a 20 year loan duration. APR ''can'' be used to show the relative impact of different payment schedules (such as balloon payments or bi-weekly payments instead of straight monthly payments), but most standard APR calculators have difficulty with those calculations.
| |
| | |
| Furthermore, most APR calculators assume that an individual will keep a particular loan until it is completely paid off resulting in the up-front fixed closing costs being amortized over the full term of the loan. If the consumer pays the loan off early, the effective interest rate achieved will be significantly higher than the APR initially calculated. This is especially problematic for mortgage loans where typical loan durations are 15
| |
| or 30 years but where many borrowers move or refinance before the loan period runs out.
| |
| | |
| In theory, this factor should not affect any individual consumer's ability to compare the APR of the same product (same duration loan) across vendors. APR may not, however, be particularly helpful when attempting to compare different products.
| |
| | |
| ====Interest-only loans====

| Since the principal loan balance is not paid down during the interest-only term, assuming there are no set up costs, the APR will be the same as the interest rate.
| |
| | |
| Three lenders with identical information may still calculate different APRs. The calculations can be quite complex and are poorly understood even by most financial professionals. Most users depend on software packages to calculate APR and are therefore dependent on the assumptions in that particular software package. While differences between software packages will not result in large variations, there are several acceptable methods of calculating APR, each of which returns a slightly different result.
