Auto Lease Calculator

Introduction

This Auto Lease Calculator estimates monthly lease payment using capitalized cost, residual value, money factor, and term. Enter MSRP, negotiated cap cost reductions, residual percentage, money factor, lease months, and taxes if the form supports them. Output approximates base payment before insurance and fees, plus total lease cost over the term. Use it to decode dealer lease worksheets and compare lease versus finance from the same vehicle MSRP.

Who this calculator is for

Drivers who prefer a new car every three years and want to know whether the payment on the window sticker is reasonable. Small business owners comparing lease mileage allowances versus buying also use it before signing closed-end lease. Shoppers cross-shopping sedans with different residual curves see why two cars at the same MSRP can lease for different payments.

Retail finance belongs in the Auto Loan Calculator. Rebate versus APR belongs in the Cash Back or Low Interest Calculator. After lease end buyout, switch to auto loan math on residual purchase price.

What it estimates

Depreciation charge is capitalized cost minus residual divided by months. Finance charge is capitalized cost plus residual times money factor each month in common approximations. Sum is pretax base payment. Residual percent times MSRP sets residual dollar value at lease end. Cap cost is MSRP minus rebates and down payment plus fees if capitalized.

Money factor times 2400 approximates APR for comparison. Zero down leases capitalize first payment or acquisition fee depending on lessor. Mileage overage and wear charges at turn-in are not in monthly payment.

Inputs explained

Use gross capitalized cost from worksheet: agreed value plus fees minus cap cost reduction.

• MSRP: Manufacturer suggested price for residual calculation.
• Selling price or cap cost: Negotiated price before tax, may differ from MSRP.
• Residual percentage: Percent of MSRP lessor guarantees at end, such as 58%.
• Money factor: Lease interest rate in factor form, such as 0.0018.
• Lease term: Months, commonly 36.
• Down payment or cap reduction: Cash due at signing reducing cap cost.
• Sales tax method (if shown): Monthly tax on payment versus tax on cap cost varies by state.

How to read the results

Monthly payment is core depreciation plus rent charge plus tax if modeled. Total lease cost is payments plus down payment plus acquisition fee if not in payment. Compare to buying same car with Auto Loan Calculator on negotiated price minus incentives.

High residual lowers payment but raises buyout at end. Low money factor reduces rent charge; manufacturer subvention often shows as lower factor. If payment differs from dealer by $20, check whether tax is monthly and whether acquisition fee is capitalized.

Worked example

MSRP $41,000, negotiated cap cost $39,000, residual 58% of MSRP equals $23,780, money factor 0.0018, 36 months, $1,500 down. Net cap cost about $37,500. Depreciation ($37,500 minus $23,780) divided by 36 about $381 per month. Average adjusted cap for finance charge about ($37,500 plus $23,780) times 0.0018 about $110. Base payment near $491 before tax.

Implied APR from 0.0018 factor is about 4.3%. Raise factor to 0.0030 and rent charge adds roughly $60 monthly. Drop residual to 52% and payment rises because you finance more depreciation. One-pay lease prepays rent; this calculator assumes monthly billing unless noted.

Practical use cases

Compare 36 versus 39 month term when lessor subsidizes one length. Evaluate mileage bump from 10k to 12k miles per year if form accepts residual adjustment. Business lease: verify tax deduction separately; calculator is payment math only.

End of lease buyout: use residual as price in Auto Loan Calculator if you finance purchase. Read auto loan financing tips for lease versus buy framework.

Limitations and related tools

Disposition fee, excess wear, mileage penalties, gap, and single-pay leases may be omitted. Open-end commercial leases differ. State tax rules vary widely and may not match your county.

How It Works

1. Enter MSRP and cap cost. Type sticker MSRP and negotiated capitalized cost after discounts.
2. Set residual and money factor. Enter residual percent and money factor from the lease worksheet.
3. Choose term and cap reduction. Select lease months and any down payment or rebates applied to cap cost.
4. Review payment and total cost. Calculate monthly payment and total lease cost. Compare implied APR to auto loan APR.

Formula and methodology

The Auto Lease Calculator uses this identity for the scenario you enter. A bank, payroll system, or tax program may round on a 360-day year or average daily balance, so a statement can differ by a small amount.
