1 Introduction   

The standard advice about leasing is that if you put a high premium on driving a new car, it might make sense to lease. Purchasing and reselling involves transaction costs, as well as uncertainty about resell value. Yet, determining whether it is “cheaper” to lease, is generally impossible since it depends on the strength of the consumer’s preferences for driving a new car and avoiding resell risk. These preferences cannot be measured in dollar terms.      

In some special cases, however, it is possible to determine whether leasing is cheaper. Consider the case of a consumer who has no strong preference for driving a new car and who, in fact, has every intention of purchasing the leased vehicle at the end of the lease period. In this case, one would expect that it would be more economical to purchase the car from the outset. Leasing a car involves an embedded call option--the right, but not the obligation, to purchase the car at a predetermined price at the end of the lease period. If one intends to purchase it anyway, leasing implies paying for an option that one does not need.     

Yet despite the embedded call option, there are a number of lease deals on the market at any time which appear to make it cheaper to lease and purchase at the end of the lease period, than to purchase the vehicle at the outset. In this paper, I propose a methodology for evaluating the cost of a lease in such cases and apply it to show evidence of underpriced leases. In addition, I explore some economic reasons behind this apparent pricing anomaly. I begin with a brief overview of the mechanics of leasing and the terminology that is used.   

2 The Mechanics of Leasing   

The most common type of lease and the  one that is under consideration in this paper is  the closed-end lease. This is the type lease  which provides the lessee (i.e., person leasing  the car) with the option to purchase the vehicle at the end of the lease period from the lessor.  The price at which the vehicle can be  purchased is known as the residual value. The  lessor may also add a purchase option fee to  that amount.     

The capital cost is price of the vehicle,  for the purposes of the lease. This price is  often negotiated before the other terms of the  lease are calculated. A downpayment paid by  the lessee is known as a capital cost reduction. The capital cost reduction might also include  the value of a vehicle that is being traded in,  and other rebates. The capital cost less the  capital cost reduction is the net capital cost  (NCC), sometimes called the adjusted capital  cost. The net capital cost can be divided into  two components: the residual value and the  depreciation of the vehicle over the lease  period.      

The monthly payment in a lease reflects  the financing costs incurred by the lessor as  well as the depreciation of the vehicle over the  lease period. The financing component is  equal to the outstanding capital cost multiplied  by a fixed percentage. This fixed percentage  is known as the lease rate or lease factor .  The outstanding capital cost in the initial  period is the NCC; each period thereafter it is  equal to the NCC minus the accumulated  depreciation. The accumulated financing  component through the life of the lease is  known as the rent charge. Federal law  requires disclosure of the rent charge, but not  of the lease rate.      

Given the usual government insistence  on full disclosure this permissable evasion is  worthy of consideration. One possible  explanation relates to the fact that, in most  states, the whole of the lease payment,  including the financing component, is subject  to sales tax. It could be reasoned that  disclosing an "interest rate" would lead  consumers to believe they are paying tax on  interest. In fact, they are not paying tax on  interest since they are not borrowing. The  lease rate reflects financing costs borne by the  lessor.     

The financing component will get  smaller over the lease period, and since the  lease payment is fixed, the depreciation  component gets larger. The lease payment is  somewhat analogous to the payment in an  amortized loan. One can think of the  depreciation paid over the lease period as  being like the principal in an amortized loan.  The difference is that the interest is being paid  not just on the remaining depreciation, but on  the remaining capital cost of the vehicle.     
  

It is always possible to compute the  lease rate from the information that must be  disclosed by law, but the computation is  somewhat complex . To further confuse  matters, car dealers, if they volunteer to  disclose the rate, will often do so by reciting  the money factor . The money factor is monthly  lease rate divided by two and, sometimes,  multipled by 1000. Thus if the monthly lease  rate is 0.0072, then the money factor could be  expressed as 0.0036, or as 3.6.      

The reason for the money factor is not  just to bamboozle the consumer. The money factor  enters into a simple formula that approximates a lease  payment. If the car dealer is working with this  formula, it would be natural to think in terms of  a money factor.

3 Methodology for Valuing a Lease   

We are considering the case of a  consumer who has no special preference for  driving a new car. Such a consumer would be  prepared to buy now and hold for longer than  the lease period, or alternatively, lease and  then buy at the residual value. What drives  the choice between an outright purchase and  the lease/purchase strategy will be the cost.     

Comparing the cost is a matter of  comparing two streams of cashflows. If the  outright purchase is done in cash, then there is  a single cash flow at time 0. If the vehicle is  financed, then there will be a stream of monthly  payments, in addition to the downpayment.  The lease/purchase strategy involves some  upfront payments, a stream of monthly  payments, and then a stream of cash flows  representing the purchase at the residual  value--this last stream could be single  payment, or a stream of cash flows if the off- lease car is financed.     

IntelliChoice , a Web based information  service, provides data on leases that we shall  use to find evidence of underpriced leases.  IntelliChoice identifies low price leases, the  best of which they give their Gold Star rating.  Their method of evaluating leases is to  calculate an ad hoc measure that they call  the “net interest rate” on the lease. This is the  interest rate used by the lessor to determine  the lease payments, augmented by various  factors.     

In this paper we look at the Gold Star  Leases available on 6/25/1998 to find  evidence of cheap leases. At that time, there  were nine leases that had the Gold Star  Rating: three Acuras, three Cadillacs, two  Saturns and a Saab.    

Our method will be to evaluate leases  from a discounted cash flow perspective.  Cash flows in the lease/purchase strategy will  be discounted and then compared with the  discounted cash flows in the outright purchase  strategy. Two measures can be computed.  The net advantage of leasing (NAL) is the  discounted cash flows of outright purchase  less the discounted cash flows of the  lease/purchase strategy. A positive NAL  implies it is cheaper to lease. This measure,  however, presupposes a rate of discount. The  break-even rate of discount (BERD) is a more  general measure for evaluating leases. The  BERD is the rate of discount at which the NAL  is zero. If the BERD on a lease is lower than  one’s opportunity cost of funds, then it is  cheaper to lease.     

Since it is generally more economical to  buy a car with cash than to finance it with a  loan, we take as the basis of comparison, an  outright purchase made by drawing down on  the consumer’s savings. If the analysis shows  that the lease/purchase strategy is cheaper  than buying the car outright with cash, then a  fortiori, it will be cheaper to lease than to  finance with an autoloan. An exception to this  conclusion is found special financing deals in  which the manufacturer offers a loan at a rate  even below what the consumer could earn in a  risk-free investment. If such an offer exists,  the appropriate comparison to the  lease/purchase strategy would be an outright  purchase using the special financing.     

For the sake of consistency, we shall  assume that if the consumer adopts the  lease/purchase strategy, he will pay cash for  the car at the residual value. Used car loans  carry higher interest rates than new car loans,  so if the consumer were to finance at the end  of the lease term, the lease/purchase strategy  would be more costly. The assumption is not  unrealistic, however, given that we are  considering a consumer with the financial  means for an outright purchase.     

In the case of the lease/purchase  strategy there is a series of 37 or 40 cash  flows. At time 0, the initial cash flow includes:      
 

  • capital cost reduction or down-payment
  • a refundable deposit
  • acquisiton fee
  • the first monthly lease payment
Lease payments are made monthly for a  period of 36 or 39 months. Once the leasing  period is complete, the final cash flow, in the  lease/purchase strategy, will be the residual  value less the deposit. Sometimes there is a  purchase option fee For the sake of our  analysis, we assume a purchase option fee of  $150.     

The payment of sales tax varies from  state to state. The most common practice, and  the one we assume, is to tax the monthly lease  payment as it is paid. We assume a sales tax  rate of 6%. We shall ignore the cost of license  and registration since it enters into both  strategies and hence washes out.    

The cash flow in the outright purchase  is simply the price of the car plus sales tax.  For the price of the car in the outright purchase strategy, we use the “target purchase price”  provided by IntelliChoice: “This is the price that you can reasonably  expect to negotiate for the vehicle as  configured; however, it is not necessarily the  lowest price. It includes an average acceptable  markup for the dealer and reflects recent  market conditions."     

Of the cars we looked at, excluding the  Saturns, the target purchase price averaged  94% of the manufacturer’s suggested retail  price (MSRP). The results of the analysis are  sensitive to the target purchase price. The  only vehicle that earned a Gold Star rating that  does not appear “cheaper to lease” under our  discounted cash flow method is the Cadillac  Catera. The difference can be attributed to the  fact that the target purchase price as a  percentage of MSRP at 88%, is lower for the  Catera than for the other vehicles listed.  

4 Evidence of "Cheap" Leases  

Using data provided by IntelliChoice, we  were able to compute the BERD on nine  leases. We found that it ranged from a low of  2.12% to a high of 7.94%. Seven of the nine  leases had BERD’s of under 5%. Thus a  consumer who considers his opportunity cost  of funds to be 5% would classify seven of the  nine leases as “cheap.”   

The results are summarized in the table below  with hyperlinks to the calculations. As a basis  of comparison, we also list the “net interest  rate” the ad hoc measure computed by  IntelliChoice, hyperlinked to Intellichoice’s data  and calculations. 

[ Sorry, hyperlinks are not operative at this time. Calculations are left as an exercise for the reader ...]    
 
Vehicle BERD Net Interest Rate
Saab 2.12% 4.26%
Saturn SC1 2.77% 5.91%
Saturn SL 2.89% 6.04%
Acura 3.2TL 3.13% 5.22%
Acura 2.5TL 3.19% 5.87%
Cadillac DeVille 4.37% 4.27%
Cadillac Eldorado 4.43% 4.71%
Acura 3.0 CL 5.29% 5.80%
Cadillac Catera 7.94% 5.73%

5 Explaining the Pricing Anomaly  

If the lease/purchase strategy is  cheaper than the outright purchase, the  implication is that the lessee is getting an  option with a price less than zero. Similarly,  the lessor is writing an option but not receiving  any compensation for doing so.    

Several explanations are possible. One  is that these special lease deals may simply be loss-leaders. They are advertised with the intent of getting the customer in the showroom  and possibly steering him to something pricier. Another hypothesis is that they are a form of  price discrimination. They allow the  manufacturer to sell more cars without  lowering the MSRP for everyone. The fact that  the underpriced leases are, in all the cases we  examined, manufacturer leases, supports this  hypothesis. A bank or independent finance  company has no incentive to offer these leases since they will not reap the profit of another car sale.   
 

Both of these explanations, however,  fail to explain why manufacturers elect to use  lease offers instead of low interest rate  financing. Unlike with financing, issuing a  lease involves assuming a residual risk. If  used car prices drop, lessees will be less likely  to exercise their option to purchase the vehicle  at the residual value and the manufacturer will  be stuck trying to sell a large number of used  cars in a weak market. Unlike with interest  rate risk, there are no derivatives that can be  used to hedge this risk.   

A plausible reason for the preference on  the part of manufacturers for leases is that  they involve much lower monthly payments  than one would find in the three to four year  autoloans that manufacturers offer. The  expectation is that consumers will be swayed  by a low monthly payment to enter into the  agreement. Even at close to zero percent  financing, a typical three year autoloan can  have payments almost double those in a three  year lease.    

Leasing as opposed to financing has  another advantage for the manufacturer. After  three years, the consumer is back at the  dealer, where the chances are high that they  will lease another car. Only about 30% of consumers purchase their leased vehicle (Koropecki, 1998 ). Contrast  this situation with that when they finance the car. After three or four years the consumer owns the car  and is less likely to purchase a new one.  Even with underpriced leases, the  manufacturer has more to gain by moving  another car, than not.   

We have shown in this paper that it can  be more economical to adopt a lease/purchase  strategy, rather than an outright purchase.  What appears to be driving this pricing  anomaly are the efforts of manufacturers to  increase sales. Leases involve low monthly  payments which allow wealth-constrained  consumers to be driving pricier vehicles.  Furthermore, the feature of a lease that brings  the consumer back to the dealer after three  years, has its marketing advantages.    

We should note, however, that we have  not drawn any conclusions about the  economical feasibility of rolling over from one  lease to another. Whether that strategy is  economical depends on how much value a  consumer attaches to driving a new vehicle, as  well as considerations such as mileage and  wear and tear. Driving an older car is almost  always cheaper than driving a new car so if  one does not have a strong reason to be  driving a new car, rolling over leases will not  usuallly be economical for the consumer-- though it will be for the manufacturer.   

The price break for the consumer who  adopts the lease/purchase strategy is  analogous to the price break for the holder of a  no-fee credit card who pays off his balance in  full. The no-fee feature is to attract the more  profligate spender. If everyone were fiscally  conservative, there would be a fee. Similarily  the cheap leases serve to rope in the profligate  who will be more prone to roll over their  leases. If everyone were capable of a present  value calculation and an honest assessment of  how important it is to drive a new car, there  might be no cheap leases.
