How the lease buyout calculator works
Estimate lease-end buyout cost, sales tax, financing payment, interest, and equity versus market value.
Total buyout = residual + purchase fee + taxes + warranty and other entered fees. Financing uses fixed-rate amortization.
Read our calculation methodology and limitations.
Example
A $24,000 residual plus tax and fees can be compared with the vehicle market value and a proposed buyout loan.
What affects the result
- Tax rules differ by state and transaction.
- A purchase-option fee may be taxable.
- Market value determines whether the buyout begins with positive or negative equity.
Frequently asked questions
Is a warranty taxable?
It depends on local law and the product. Use the Sumvoro tax-treatment control to match the quote.
Is residual value the full buyout price?
Usually not. Sales tax, a purchase-option fee, registration, inspection, and other charges may also apply.
