This calculator uses standard lease formulas (residual = MSRP×%, depreciation = (AdjCap−Residual)/term, rent charge = (AdjCap+Residual)×MF). :contentReference[oaicite:9]{index=9}

Actual payments, taxes, fees, and terms vary by state/county/city, vehicle type, lender/lessor, credit approval, dealer disclosures, and contract structure. Results may not reflect your final retail installment contract or lease agreement.

Always confirm all numbers and terms with your dealer, lender/lessor, and your local tax authority before signing.

How Lease Payments Are Actually Calculated

Lease quotes can look “simple,” but most of the cost is hidden inside a few numbers: cap cost, residual, and money factor. If any of those are off, your payment moves fast.

MSRP

The sticker price. MSRP is used to calculate your residual value, even if you negotiate a lower selling price.

Selling Price / Cap Cost

The negotiated price used to start the lease. This is where most people should focus first—before talking payment.

Residual % → Residual Value

Residual Value = MSRP × Residual %. Higher residual = lower depreciation = lower payment.

Adjusted Cap Cost

Adjusted Cap Cost = (Cap Cost + capitalized fees/add-ons + negative equity) − (rebates + cap reduction + trade equity).

Depreciation Portion

Depreciation = (Adjusted Cap Cost − Residual Value) ÷ Term. This is the “wear-and-tear” you’re paying for.

Rent Charge (Finance Portion)

Rent Charge = (Adjusted Cap Cost + Residual Value) × Money Factor. Money factor is basically interest. Dealers can mark it up.

Integrity Carbuyer rule:

Don’t judge a lease by the monthly payment alone. A “good payment” can be built with a marked-up money factor, hidden add-ons, or a padded cap cost. Always verify the money factor and residual match the lender program.
