Use our Lease Calculator to quickly estimate your monthly payment, taxes, due-at-signing, and total lease cost before you visit the dealership. Understand how money factor, residual value, and cap cost reductions work together so you can negotiate with confidence.
How the Lease Calculator Works
Leasing a vehicle involves a handful of inputs that determine your payment. The most important are the negotiated selling price, the residual value, the money factor, your lease term, and any fees, incentives, or cash you put down. Our Lease Calculator combines these inputs to deliver a clear monthly estimate and a full cost breakdown.
Here’s the basic math behind the scenes: the calculator finds your adjusted capitalized cost (selling price plus bank/doc fees, minus any cash down, trade-in credit, and rebates). It then calculates depreciation by subtracting the residual value from the adjusted cap cost and spreading that difference evenly across your lease term. The finance charge comes from multiplying the sum of the adjusted cap cost and residual by the money factor. Add depreciation and finance together for the base payment, then apply sales tax (in states where tax is assessed monthly) to get your estimated monthly payment with tax.
Key Terms You Should Know
- MSRP: The manufacturer’s suggested retail price. Residual percentage is usually applied to MSRP, not the negotiated price.
- Negotiated Price (Cap Cost): The price you and the dealer agree on before incentives. Lowering this number lowers your payment.
- Residual Value: The projected value of the vehicle at lease end, expressed as a percentage of MSRP.
- Money Factor (MF): The lease’s interest rate. As a rule of thumb, APR / 2400 ? MF.
- Adjusted Cap Cost: Your net amount financed after fees and cap cost reductions (cash, trade, rebates).
Steps to Use the Lease Calculator
- Enter the vehicle’s MSRP and your negotiated selling price.
- Add any fees (acquisition/bank fee and other upfront fees).
- Enter cap cost reductions (cash down, trade-in value, and rebates).
- Provide the lease term in months, the residual percentage, and the money factor.
- Add your local sales tax rate if applicable.
- Submit to see monthly payment, due at signing, and total cost.
Tips to Lower Your Lease Payment
There are several levers you can pull to reduce your monthly lease cost. The most impactful is the negotiated selling price: shop around for quotes and ask for a detailed out-the-door worksheet. Captive finance incentives and rebates can meaningfully reduce your cap cost, so be sure to check for loyalty, conquest, military, college grad, or regional offers. A higher residual and a lower money factor also help. You can’t directly control residuals, but you can choose models and trims with stronger resale projections. For the money factor, excellent credit and captive financing often yield better rates.
Another strategy is to balance your due-at-signing amount with your monthly payment. While putting cash down can lower your payment, large down payments can be risky if the vehicle is stolen or totaled early in the term. Instead, consider keeping down payment modest and focus on securing a competitive selling price and money factor.
What the Results Mean
Your results include base monthly payment, estimated sales tax, and the monthly total. You’ll also see an estimated due at signing that typically includes your first month’s payment, acquisition fee, other upfront fees, and any cash down (less applicable rebates). Finally, the calculator estimates your total lease cost and an effective monthly that averages all costs across the full term. Use these figures to compare offers across dealers and to understand how each term affects your budget.
Common Mistakes to Avoid
- Comparing deals by payment only. Always compare selling price, money factor, residual, and fees.
- Ignoring fees. Acquisition and doc/DMV fees can meaningfully affect your due-at-signing and total cost.
- Misreading money factor. Ensure you convert APR to MF correctly (APR / 2400).
- Underestimating taxes. States differ on how and when tax is applied; our default applies it monthly.
