Car Lease Calculator - Vehicle Leasing Payment Tool

How Car Lease Calculation Works

Monthly Payment = (Depreciation + Finance Charge) / Lease Term, where Depreciation = (Cap Cost - Residual) and Finance Charge = (Cap Cost + Residual) × Money Factor

Lease payments are based on the vehicle's depreciation during the lease term plus a finance charge. You pay for the portion of the car's value you use, not the whole vehicle. The money factor (similar to interest) and residual value (predicted end value) determine your payment.

  1. 1

    Enter Vehicle Price

    Input MSRP and negotiated cap cost (selling price)

  2. 2

    Set Lease Terms

    Enter lease duration (typically 24, 36, or 48 months)

  3. 3

    Enter Money Factor

    Input the money factor (multiply by 2400 to get approximate APR)

  4. 4

    Set Residual Value

    Enter residual percentage (typically 50-60% for 3 years)

Tips

  • 1

    Negotiate the cap cost (selling price) just like you would when buying

  • 2

    Higher residual values mean lower monthly payments

  • 3

    Money factor times 2400 equals approximate APR for comparison

  • 4

    Consider total cost over lease term, not just monthly payment

  • 5

    Watch for excess mileage and wear charges at lease end

Common Mistakes

  • Not negotiating the selling price (cap cost) before discussing payments

  • Choosing lease terms longer than the warranty period

  • Underestimating mileage needs and facing excess mileage fees

  • Ignoring wear and tear guidelines that can result in end-of-lease charges

FAQs

What is a money factor?

Money factor is the lease equivalent of interest rate. Multiply by 2400 to convert to approximate APR. A money factor of 0.00125 equals about 3% APR. Lower is better.

What is residual value?

Residual is the predicted value of the car at lease end, expressed as a percentage of MSRP. Higher residuals mean lower payments because you're financing less depreciation. Residuals are set by the leasing company.

How many miles can I drive on a lease?

Standard leases allow 10,000-15,000 miles per year. Excess mileage charges are typically $0.15-0.30 per mile. If you drive more, negotiate higher mileage upfront - it's cheaper than paying overage.

Can I negotiate a lease?

Yes! Negotiate the cap cost (selling price) just like buying. You can also sometimes negotiate money factor with well-qualified credit. Residuals are fixed by the manufacturer and not negotiable.
