Car Lease Calculator – Payment, Money Factor, Residual & Total Cost
Pro car lease calculator: enter MSRP, cap cost, money factor or APR, residual %, fees and taxes to get monthly payment (pre/post tax), due at signing, rent charge, depreciation, and cost-per-mile with an exportable month-by-month breakdown.

Vehicle pricing
Rate & residual
Entering APR updates the money factor automatically and vice versa.
Enter an absolute number if your dealer already gave you a residual value.
Used for labeling the amortization schedule.
How to Use This Calculator
Use this professional-grade car lease calculator to capture every input that matters: MSRP, negotiated price, money factor/APR, residual value, fees, taxes, and mileage. The tool mirrors how lenders build a lease so you can compare offers with confidence.
Step-by-step instructions
- Enter the Manufacturer's Suggested Retail Price (MSRP) and negotiated cap cost before any reductions.
- Supply down payment, rebates, trade-in credit, acquisition fee, and DMV/title fees to compute the adjusted capitalized cost.
- Choose the lease term (months) and the money factor. Input APR instead to convert automatically.
- Provide the residual % of MSRP or override it with the absolute residual value your dealer quoted.
- Set the sales tax / VAT rate and pick the treatment used in your state (per-payment, upfront, or none).
- Track mileage allowance and the first payment month; results refresh whenever you hit Calculate or change inputs.
Methodology
Calculations rely on the standard leasing math used by dealers and captive finance companies. We compute the adjusted capitalized cost, apply the money factor to the balance plus the residual, and decree the depreciation component to arrive at the base payment. Tax treatment follows your selector, and the schedule simulates each monthly payment with running totals.
- Adjusted cap cost = negotiated price − cash due − rebates − trade + fees.
- Residual value defaults to MSRP × residual % but accepts an override.
- Depreciation = (adjusted cap cost − residual) ÷ term.
- Rent charge = (adjusted cap cost + residual) × money factor.
- Monthly payment (pre-tax) = depreciation + rent charge; taxes and upfront obligations layer on afterward.
Why this beats other calculators
- Transparent split of depreciation versus rent charge plus selectable tax routing.
- Due-at-signing, total out-of-pocket, and cost-per-mile let you compare stateside offers.
- Copyable schedule, CSV export, shareable URL, and print-friendly layout for dealer conversations.

Data source & methodology
This calculator is aligned with the CFPB's Regulation M for consumer leasing and implements industry formulas for depreciation, rent charge, and tax treatment. Inputs are surfaced directly so you can verify how each assumption influences the monthly payment and total cost.

Worked example
Scenario: MSRP $40,000, negotiated price $37,000, 36-month term, residual 60%, money factor 0.0020 (≈ 4.8% APR), acquisition fee $650 (capitalized), down payment $2,000, and 8% tax on the monthly payment.
1. Adjusted cap cost: C_adj = (37,000 + 650) − 2,000 = $35,650
2. Residual: V_res = 40,000 × 0.60 = $24,000
3. Depreciation: D = (35,650 − 24,000) ÷ 36 = $326.39
4. Rent charge: F = (35,650 + 24,000) × 0.0020 = $119.30
5. Monthly base: M_base = D + F = $445.69
6. Tax (monthly): T_mo = 445.69 × 0.08 = $35.66 → Monthly with tax = $481.35
Key factors that affect your lease payment
Residual value impact: Higher residuals lower the depreciation portion, so you pay for less of the car's value. Residuals depend on term, mileage, and projected market value.
Money factor vs. APR: Leasedollars use the money factor as the finance rate. Multiply MF × 2400 to compare with APRs.
Capitalized cost reductions: Down payments, rebates, and trade-in credits reduce the financed amount, but upfront cash may be lost if the vehicle is totaled.
Mileage allowances: Higher mileage allowances cut residuals, raising payments. Track miles per year to estimate cost per mile and potential overage fees.
Frequently asked questions
How do I convert APR to money factor?
Use MF = APR ÷ 2400. For example, 4.8% APR is approximately 0.0020 MF. The calculator keeps both fields synchronized so you can enter either.
Is residual value based on MSRP or negotiated price?
Residual value is almost always expressed as a percentage of MSRP. Use the override only if the lessor provides an absolute residual dollar amount.
Does tax apply to each lease payment?
It depends on your state. Some regions tax each payment, some tax the total upfront, and others tax the entire vehicle price when leasing. Pick your tax treatment so the calculator matches local rules.
What is due at signing?
Usually the first payment, acquisition/doc fees, DMV/title, plus any cash due (down payment) minus rebates and trade-in credits. The calculator includes all of these factors in the due-at-signing figure.
How do mileage limits affect the payment?
Higher mileage allowances reduce the residual, which increases the depreciation charge. Plan the allowance carefully to avoid excess-mileage penalties.
Can I compare leasing vs. buying?
Yes. Use this tool for the lease side and see our loan amortization calculator to compare total cost of ownership and equity.
Lease vs. buy decision factors
- Monthly cash flow: Leases usually charge less per month than loans.
- Ownership: You do not own a leased vehicle, while loans eventually build equity.
- Mileage: Leases impose mileage limits; loans have no annual caps.
- Wear and tear: Leases may bill for excess wear; purchases are yours to maintain.
- Latest models: Leasing lets you drive new cars every few years; buying keeps the car longer.
- Total cost: Over multiple terms, leasing can cost more than buying and keeping a vehicle.
