About Car Lease Buyout Calculator
The Car Lease Buyout Calculator calculates the total cost to purchase your leased vehicle at or before lease-end based on contractual residual value, purchase option fees, state sales tax, and buyout loan financing.
Formula & Mathematical Calculation
Total Buyout Cost = Residual Value + Purchase Option Fee + ( Residual Value × Sales Tax Rate ) + Registration Fees
Monthly Buyout Loan Payment = Total Buyout Cost × [ r(1 + r)^n ] / [ (1 + r)^n - 1 ]
Calculation Example
Example: Residual Value: $20,000 | Purchase Fee: $350 | Sales Tax: 7% ($1,400). Total Buyout = $21,750. Financed for 48 Months @ 6.5% APR → Monthly Payment = $515.65/month.
