About the Car Lease vs Buy Calculator

### Why Use the Car Lease vs Buy Calculator Calculator?
The Car Lease vs Buy Calculator is a valuable tool for individuals who are trying to decide whether to lease or buy a car. This decision can be complex, as it involves considering various factors such as the car's price, lease payment, lease term, and other costs associated with leasing or buying. The calculator helps users make an informed decision by providing a clear comparison of the total costs of leasing and buying. It takes into account the car's MSRP, monthly lease payment, lease term, and other relevant factors to calculate the total lease cost, total buy cost, and lease advantage. This information enables users to determine which option is more cost-effective for their specific situation.

For example, a person who drives a lot may prefer to buy a car, as lease agreements often come with mileage limits and excessive mileage fees. On the other hand, someone who wants a new car every few years may find leasing more appealing, as it allows them to drive a new vehicle without the long-term commitment of ownership. The calculator helps users like these make a decision that suits their driving habits and financial situation.

### History of the Car Lease vs Buy Calculator
The concept of leasing a car originated in the 1950s and 1960s, when companies began offering fleets of vehicles to businesses. However, it wasn't until the 1970s and 1980s that leasing became more widespread among individual consumers. During this time, car manufacturers and dealerships started to offer leasing options as a way to make cars more affordable and attractive to a wider range of buyers.

The development of the Car Lease vs Buy Calculator is closely tied to the evolution of leasing and financing options in the automotive industry. As leasing became more popular, there was a growing need for tools that could help consumers compare the costs of leasing and buying. In response, financial experts and software developers created calculators that could take into account various factors such as the car's price, lease payment, and lease term.

One of the key figures in the development of leasing calculations is Frank J. Fabozzi, an American economist and expert in the field of finance. In his book "Financial Management and Analysis," Fabozzi provides a detailed explanation of the concepts and formulas used in leasing calculations. While he did not specifically develop the Car Lease vs Buy Calculator, his work on leasing and finance has contributed significantly to the understanding and development of the tools used in this field.

### The Science Behind the Calculations
The Car Lease vs Buy Calculator uses a combination of mathematical formulas to calculate the total lease cost, total buy cost, and lease advantage. The calculations involve the following variables:

- Car MSRP (purchase price)
- Monthly lease payment
- Lease term (in months)
- Due at signing (cap cost reduction + fees)
- Down payment (if buying)
- Loan APR (if buying)
- Expected depreciation over lease term

The total lease cost is calculated by multiplying the monthly lease payment by the lease term and adding the due at signing. The total buy cost is calculated by subtracting the down payment from the car's MSRP, adding the total interest paid over the loan term, and subtracting the expected resale value of the car.

The lease advantage is calculated by subtracting the total lease cost from the total buy cost. A positive result indicates that leasing is the more cost-effective option, while a negative result indicates that buying is the better choice.

The formula for the total lease cost is:

Total Lease Cost = (Monthly Lease Payment x Lease Term) + Due at Signing

The formula for the total buy cost is:

Total Buy Cost = Car MSRP - Down Payment + Total Interest - Resale Value

The formula for the lease advantage is:

Lease Advantage = Total Buy Cost - Total Lease Cost

### Real-Life Application and Examples
Let's consider an example of how the Car Lease vs Buy Calculator can be used in a real-world scenario. Suppose John is considering leasing a car with an MSRP of $38,000. The monthly lease payment is $500, and the lease term is 36 months. John also has the option to buy the car with a down payment of $5,000 and a loan APR of 6.9%. The expected depreciation over the lease term is 40%.

Using the calculator, John enters the following inputs:

- Car MSRP: $38,000
- Monthly lease payment: $500
- Lease term: 36 months
- Due at signing: $3,000
- Down payment: $5,000
- Loan APR: 6.9%
- Expected depreciation: 40%

The calculator returns the following outputs:

- Total Lease Cost: $23,640
- Total Buy Cost: $34,419
- Lease Advantage: $10,779
- Car Value at Lease End: $22,800

Based on these results, John can see that leasing the car would cost him a total of $23,640 over the 36-month lease term, while buying the car would cost him a total of $34,419. The lease advantage of $10,779 indicates that leasing is the more cost-effective option for John. Additionally, the car's value at the end of the lease term is estimated to be $22,800, which is 60% of its original MSRP.

John can use this information to make an informed decision about whether to lease or buy the car. If he plans to drive the car for an extended period, buying may be the better option. However, if he wants a new car every few years and doesn't mind the mileage limits and fees associated with leasing, then leasing may be the way to go. The Car Lease vs Buy Calculator provides John with a clear and detailed comparison of the costs involved, enabling him to make a decision that suits his needs and financial situation.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

Lease total cost = (monthly payment x term) + due at signing
Buy total cost (net) = down payment + (monthly payment x term) - estimated resale value at end of period
Lease advantage = buy net cost - lease total (positive = buying costs more = lease wins)

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: New BMW 3 Series: $48,000 MSRP, lease $599/mo 36 months vs. buy at 7% APR

Inputs

car_price: 48000 lease_payment: 599 lease_months: 36 months lease_due_at_signing: 3500 buy_down: 5000 buy_rate: 7 depreciation_pct: 42
Total Lease Cost: $25,064. Total Buy Cost: $24,958. Lease Advantage: $106. Car Value at Lease End: $27,840

With Car MSRP / Purchase Price = 48,000, Monthly Lease Payment = 599, Lease Term = 36 months and Due at Signing = 3,500 as the stated inputs, the result is Total Lease Cost = $25,064, Total Buy Cost = $24,958 and Lease Advantage = $106. Each value corresponds to the declared output fields.
