Free Lease Calculator: input loan amount, residual value, interest rate, and months to instantly see monthly payment, total cost, and interest. Reliable results every time.
A lease calculator is a financial tool that helps you estimate your monthly lease payments based on four key inputs: loan amount, residual value, interest rate, and lease term (in months). It uses a standard lease payment formula incorporating the POW (power) and PREC (precision) functions to deliver accurate, rounded results instantly.
The loan amount refers to the capitalized cost of the asset being leased — typically the negotiated price of a vehicle or equipment. This is the starting value before subtracting any down payment or trade-in credits. In our calculator, the default example uses $20,000.
Residual value is the estimated worth of the leased asset at the end of the lease term. It is set by the lessor (e.g., a dealership or leasing company) and directly impacts your monthly payment — the higher the residual value, the lower your monthly payment, because you’re only financing the depreciation portion of the asset.
The monthly payment is calculated using the following logic: Depreciation fee = (Loan Amount − Residual Value) ÷ Number of Months, Finance fee = (Loan Amount + Residual Value) × Monthly Interest Rate, and Monthly Payment = Depreciation Fee + Finance Fee. This formula is consistent with industry-standard lease payment calculations used by banks and auto finance companies.
This is the annual interest rate (also called the Money Factor annualized) expressed as a percentage. The calculator converts it to a monthly rate internally (Annual Rate ÷ 12) to compute your finance charge. For example, a 7.5% annual rate becomes 0.625% per month.
Total Payment = Monthly Payment × Number of Months — the total amount you pay over the full lease term, and Interest Amount = Total Payment − (Loan Amount − Residual Value) — the total financing cost, i.e., how much you pay above the asset’s depreciation. In the example shown, a $20,000 loan at 7.5% over 36 months results in $3,448.16 in interest charges.
Yes. The formula used mirrors the standard automotive lease calculation methodology. However, actual dealer quotes may vary slightly due to acquisition fees, taxes, insurance requirements, or mileage caps that are not reflected in this calculator. Always use this tool as a planning estimate and consult a licensed financial advisor for binding lease agreements.
Yes. While commonly used for auto leases, this calculator applies to any fixed-term lease with a defined residual value, including equipment financing and certain commercial property leases. The math is universal as long as you have a loan amount, residual value, interest rate, and defined term.
Setting the residual value to $0 effectively turns this into a standard installment loan calculator. In this case, you are financing 100% of the asset’s value with no buyout consideration at the end — similar to a traditional auto loan or equipment finance agreement.
