The calculator will display your estimated monthly payment, total interest paid, and total cost of the lease. You can also view a breakdown of your payments over time.

Formula Used

The calculator uses the following formulas to determine lease details:

Monthly Payment = P * (r(1 + r)^n) / ((1 + r)^n - 1) Where: P = Principal (Vehicle Price - Down Payment) r = Monthly Interest Rate (Annual Rate / 12) n = Number of Payments (Lease Term in Months)

Additional calculations include:

Total Interest Paid = (Monthly Payment × Number of Payments) - Principal
Total Cost of Lease = Monthly Payment × Number of Payments

Worked Example

Let's calculate a lease for a $30,000 vehicle with a $3,000 down payment, 36-month term, and 3.5% annual interest rate.

Given:

Vehicle Price: $30,000
Down Payment: $3,000
Lease Term: 36 months
Annual Interest Rate: 3.5%

Step 1: Calculate the principal (P):

P = $30,000 - $3,000 = $27,000

Step 2: Calculate the monthly interest rate (r):

r = 3.5% / 12 = 0.0029167 (0.29167%)

Step 3: Calculate the monthly payment:

Monthly Payment = $27,000 × (0.0029167(1 + 0.0029167)^36) / ((1 + 0.0029167)^36 - 1) Monthly Payment ≈ $812.34

Step 4: Calculate total interest paid:

Total Interest = ($812.34 × 36) - $27,000 = $2,964.64

Step 5: Calculate total cost of lease:

Total Cost = $812.34 × 36 = $29,244.24

This example shows that leasing this vehicle would cost approximately $29,244.24 over 3 years, with $2,964.64 paid in interest.

Lease vs. Purchase Comparison

Here's a comparison between leasing and purchasing a vehicle with the same example values:

Metric	Lease	Purchase
Initial Cost	$3,000 (down payment)	$3,000 (down payment)
Monthly Payment	$812.34	$437.50 (assuming 5% down and 60-month loan at 4.5%)
Total Interest Paid	$2,964.64	$1,750.00
Total Cost Over 3 Years	$29,244.24	$29,250.00
Ownership After Term	Must return vehicle	Own vehicle

This comparison shows that in this scenario, leasing and purchasing have similar total costs, but leasing requires returning the vehicle at the end of the term. The choice between leasing and purchasing depends on your financial situation and long-term plans.

Frequently Asked Questions

What is the difference between leasing and financing a car?

Leasing typically involves shorter terms (2-4 years) and requires returning the vehicle at the end. Financing allows you to own the vehicle after the loan is paid off, usually over longer terms (3-7 years).

Can I get a lower monthly payment by leasing?

Leasing often results in higher monthly payments than financing because you're paying for the vehicle's depreciation over the lease term. Financing typically offers lower monthly payments because you're paying off the loan over a longer period.

What happens at the end of a lease?

At the end of a lease, you have options to return the vehicle, purchase it, or extend the lease. The lessee typically pays a fee to return the vehicle, which may be higher than the remaining loan balance if you were financing.

Are there any hidden fees in car leases?

Yes, leases often include fees for registration, insurance, taxes, and administrative costs. Always review the lease agreement carefully to understand all associated fees before signing.

Can I negotiate the lease terms?

Yes, you can often negotiate lease terms with the dealer, including the down payment, monthly payment, and lease duration. Some dealers may offer special financing or lease packages.
