Lease Payment Calculator

How to Use the Lease Payment Calculator

This calculator estimates your monthly lease payment using the standard formula: Monthly Payment = (Depreciation + Finance Charge) ÷ Lease Term. Follow these steps:

1. Enter Vehicle Price – The total cost of the vehicle (e.g., $30,000). Must be a positive number.
2. Enter Down Payment – Any upfront cash you pay (optional, can be $0).
3. Enter Trade-In Value – Value of your trade-in vehicle (optional, can be $0).
4. Enter Lease Term – The number of months (e.g., 36). Must be a whole number ≥ 1.
5. Enter Money Factor – The interest rate expressed as a decimal (e.g., 0.00125). To convert APR to money factor, divide APR by 2400 (e.g., 3% APR = 0.03 ÷ 2400 = 0.00125).
6. Enter Residual Value – The car’s estimated value at lease end (e.g., $15,000). Must be less than the net cap cost (vehicle price minus down payment and trade-in).
7. Click "Calculate" – Your monthly payment appears below. If inputs are invalid, error messages guide you.

Note: All monetary values are in US dollars ($). The calculator automatically computes Net Cap Cost = Vehicle Price – Down Payment – Trade-In. Ensure the residual value does not exceed the net cap cost.
