Reverse Lease Calculator - Catch Dealer Markups
Perfect for the dealership! Dealer says "This car leases for $450/month"? Enter that quote and we'll reverse-calculate their APR and effective selling price. No more "don't worry about the rate" BS!
How the math works
Calculation paths:
โข Direct โ If you enter the Total Lease Charge or the dealer-quoted APR, the result is exact.
โข Iterative estimate โ If neither is supplied, the app finds the lowest realistic APR that balances the payment; this is an educated estimate, not a guaranteed rate.
Disclaimer: This tool is for educational use only. Calculations are based on industry-standard lease formulas and the numbers you provide. Programs, fees and taxes differ by lender and jurisdiction; always confirm figures with your dealer or finance office before signing any contract.
