Car Lease Calculator
Monthly lease payment, total cost, effective APR & lease vs. buy comparison
A car lease is a long-term rental where you pay for the vehicle's depreciation during the lease term, not its full value. This calculator uses the standard automotive lease formula — depreciation charge + finance charge + tax — to compute your exact monthly payment and total lease cost, then compares it against financing the same vehicle.
How Car Lease Payments Are Calculated
The automotive lease payment formula is standardized across all manufacturers. Your payment covers two things: the depreciation you use during the lease, plus a finance charge on the money the dealer has tied up in the vehicle.
| Term | Definition |
|---|---|
| Net Cap Cost | The effective loan amount — negotiated price adjusted for down payment, trade-in, and fees |
| Residual Value | MSRP × Residual % — what the car is worth at lease end; set by the manufacturer |
| Money Factor | Lease interest rate expressed as a decimal; multiply by 2,400 to convert to APR |
| Acquisition Fee | Dealer/lender admin fee ($500–$1,200), typically added to cap cost |
Example: A $40,000 MSRP car, negotiated to $38,000, $2,000 down, 55% residual ($22,000), money factor 0.00150, 36-month term, 8% tax. Net Cap Cost: $37,595. Depreciation: ($37,595 − $22,000) ÷ 36 = $433/mo. Finance: ($37,595 + $22,000) × 0.00150 = $89/mo. Base: $522. With 8% tax: $564/month.
🚗 Expert Pro-Tip
Never Put a Large Down Payment on a Lease: On a purchase, a big down payment reduces your loan and builds equity. On a lease, a large down payment reduces your monthly payment but does NOT reduce your total cost — and if the car is totaled or stolen, you lose that money since gap insurance pays the leasing company, not you. Instead, put the minimum down (often $0) and invest the difference. The best lease deals come from high residual values (65%+) and low money factors — both set by the manufacturer, not negotiable. Focus on negotiating the selling price (cap cost) — even $1,000 off saves $27/month on a 36-month lease.
Frequently Asked Questions: Car Leasing in 2026
How is a car lease payment calculated?
A car lease payment has two components: depreciation charge and finance charge. Depreciation = (Net Cap Cost − Residual Value) ÷ months. Finance = (Net Cap Cost + Residual Value) × money factor. Add together and multiply by (1 + sales tax) for your monthly payment. Everything else is noise — negotiate the cap cost (selling price) and verify the money factor is at buy rate.
What is money factor in a car lease?
Money factor is the lease interest rate expressed as a small decimal. Multiply by 2,400 to get the equivalent APR. A money factor of 0.00150 = 3.6% APR. Manufacturers set "buy rate" money factors monthly — always ask the dealer to verify you're getting buy rate, not a marked-up rate (dealers can mark up money factor to earn more profit, which looks like a tiny change but costs hundreds over the lease term).
Is leasing or buying a car better financially?
Leasing is cheaper short-term but more expensive long-term. Someone who perpetually leases pays for a new car every 3 years forever. Someone who buys a car and keeps it 8–10 years pays zero car payments for years 4–10. Over 15 years, the long-term buyer saves $30,000–$60,000 compared to the perpetual lessee. Lease only if: business use (deductible), technology changes rapidly (EVs), or total cost of ownership favors it (verify with this calculator).
Can I negotiate a car lease?
Yes — negotiate the selling price (cap cost) exactly like a purchase. A lower cap cost directly reduces your monthly payment. You cannot negotiate residual value or money factor (set by the manufacturer). What you can do: get competing quotes from multiple dealers, negotiate dealer-added fees, and time your lease for manufacturers offering subvented (subsidized) lease deals with high residuals and low money factors.
