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 auto leasing calculator uses the following formula to calculate monthly payments:
Monthly Payment Formula
Monthly Payment = P × (r × (1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal amount (Vehicle price - Down payment)
- r = Monthly interest rate (APR ÷ 12 ÷ 100)
- n = Number of payments (Lease term in months)
This formula calculates the fixed monthly payment for a lease with a constant interest rate.
Worked Example
Let's calculate the monthly payment for a $30,000 vehicle with a 36-month lease, $3,000 down payment, and 3.5% APR.
- Principal amount = $30,000 - $3,000 = $27,000
- Monthly interest rate = 3.5% ÷ 12 = 0.0029167
- Number of payments = 36
- Monthly payment = $27,000 × (0.0029167 × (1 + 0.0029167)^36) / ((1 + 0.0029167)^36 - 1)
- Monthly payment ≈ $825.50
Total interest paid = $825.50 × 36 - $27,000 = $1,650.20
Total cost of lease = $30,000 + $1,650.20 = $31,650.20
Lease vs. Buy Comparison
Compare the costs of leasing versus buying a vehicle:
| Factor | Lease | Buy |
|---|---|---|
| Upfront Cost | Down payment + fees | Down payment + taxes/fees |
| Monthly Payment | Fixed amount | Mortgage payment (varies) |
| Ownership | No ownership (must return vehicle) | Full ownership after payments |
| Mileage Limit | Yes (penalties for overage) | No limit |
| Depreciation | You keep depreciation | Vehicle loses value |
Leasing is typically better for short-term use or when you want to drive a new car each year. Buying is better for long-term ownership and when you can afford the down payment.
