Formula Used

The monthly payment for an auto lease is calculated using the following formula:

Monthly Payment = P × (r × (1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal amount (vehicle price minus down payment)
r = Monthly interest rate (APR ÷ 12 ÷ 100)
n = Number of payments (lease term in months)

This formula uses the standard loan payment calculation method, which accounts for the present value of all future payments.

Worked Example

Let's calculate a lease for a $30,000 vehicle with a $3,000 down payment, 36-month term, and 3.9% APR.

Principal amount = $30,000 - $3,000 = $27,000
Monthly interest rate = 3.9% ÷ 12 = 0.325%
Number of payments = 36
Using the formula: Monthly Payment = $27,000 × (0.00325 × (1 + 0.00325)^36) / ((1 + 0.00325)^36 - 1)
Calculated monthly payment = $768.45
Total interest paid = ($768.45 × 36) - $27,000 = $1,626.20
Total amount paid = $27,000 + $1,626.20 = $28,626.20

Frequently Asked Questions

What is the difference between leasing and financing a car?: Leasing typically involves shorter terms (24-48 months) and higher monthly payments, but you don't own the vehicle at the end. Financing usually has longer terms (36-72 months) and you own the vehicle at the end.
Can I get a lower lease payment by making a larger down payment?: Yes, increasing your down payment reduces the principal amount you need to finance, which can lower your monthly payment.
What happens if I want to return the car early?: Early return fees typically apply, which can be significant. Check your lease agreement for specific early termination terms.
Are there any fees associated with leasing through Ally Bank?: Yes, Ally Bank may charge fees for document processing, title fees, and other administrative costs. These fees are usually disclosed in your lease agreement.
