How Car Lease Payments Are Calculated
A car lease payment has two components — depreciation fee and finance charge. The depreciation fee covers the loss in vehicle value over the lease term. The finance charge is the interest cost of leasing. Understanding these components helps you negotiate a better lease deal.
Adjusted Cap Cost = Sale Price - Down Payment
Residual Value = MSRP × Residual Percentage
Depreciation Fee = (Adjusted Cap Cost - Residual Value) / Lease Term (months)
Finance Charge = (Adjusted Cap Cost + Residual Value) × Money Factor
Base Monthly Payment = Depreciation Fee + Finance Charge
Monthly Tax = Base Monthly Payment × Tax Rate
Total Monthly Payment = Base Monthly Payment + Monthly Tax
APR = Money Factor × 2400
Understanding Money Factor
Money factor is the lease equivalent of an interest rate. To convert money factor to APR multiply by 2400. For example a money factor of 0.00125 equals an APR of 3% (0.00125 × 2400 = 3.0%). Always ask the dealer for the money factor when negotiating a lease — a lower money factor means lower finance charges.
What is Residual Value?
Residual value is the estimated worth of the vehicle at the end of the lease term expressed as a percentage of MSRP. A higher residual value means lower monthly payments because you are only paying for less depreciation. Vehicles that hold their value well (like Honda, Toyota) typically have higher residual values and therefore lower lease payments.
Key Tips for Getting a Better Lease Deal
- Negotiate the sale price first — lower cap cost = lower payment
- Ask for the money factor — compare to current market rates
- Look for vehicles with high residual values
- Avoid paying too much down — down payments on leases are not refundable if the car is totaled
- Check manufacturer lease deals — often include subsidized money factors

Car Lease Calculator — Complete Guide
Leasing a car can be significantly cheaper month-to-month than buying but understanding the numbers is essential to getting a good deal. Our lease calculator uses the same formula that dealers use giving you full transparency on every component of your payment.
How Is a Car Lease Payment Calculated?
Monthly Lease Payment Formula:
Depreciation Fee = (Adjusted Cap Cost - Residual Value) ÷ Term
Finance Charge = (Adjusted Cap Cost + Residual Value) × Money Factor
Base Payment = Depreciation Fee + Finance Charge
Monthly Payment = Base Payment + Tax
Example — $35,000 car, $33,000 sale price, 55% residual:
Residual Value = $35,000 × 55% = $19,250
Depreciation = ($33,000 - $19,250) ÷ 36 = $381.94/mo
Finance Charge = ($33,000 + $19,250) × 0.00125 = $65.31/mo
Base Payment = $447.25/mo (+ tax)
Lease vs Buy — Which Makes More Financial Sense?
Leasing almost always has lower monthly payments than buying but buying builds equity. Leasing makes sense if you drive under 12,000 miles per year, want a new car every 2-3 years, use the car for business and can deduct payments, or value predictable costs with warranty coverage. Buying makes sense if you drive over 15,000 miles per year, keep cars long-term, want full ownership freedom or plan to modify the vehicle.
Key Lease Terms Explained
- Money Factor: The lease equivalent of an interest rate. Multiply by 2,400 to get approximate APR. A money factor of 0.00125 = 3% APR.
- Residual Value: The estimated value of the car at lease end expressed as a percentage of MSRP. Higher residual = lower monthly payment.
- Cap Cost Reduction: Your down payment on a lease. Unlike buying a car a down payment on a lease is generally not recommended as you lose it if the car is totalled.
- Acquisition Fee: A one-time fee charged by the leasing company typically $400-$900. Always ask for this to be waived or reduced.

Frequently Asked Questions
How is a car lease payment calculated? +
A lease payment has two parts. First the depreciation fee — divide the difference between the negotiated price and residual value by the lease term in months. Second the finance charge — add the negotiated price and residual value then multiply by the money factor. Add both together and apply sales tax for your total monthly payment. Use our calculator above for instant results.
Is leasing or buying a car better? +
Leasing is better if you want lower monthly payments, prefer a new car every 2-3 years and drive under 12,000-15,000 miles annually. Buying is better if you drive a lot, want to own the vehicle long term, plan to modify it or want to build equity. Over 10 years buying almost always costs less than continuous leasing since you eventually own the vehicle outright.
What is a good money factor for a car lease? +
A good money factor depends on current interest rates. Multiply any money factor by 2400 to get the equivalent APR. In a low interest rate environment a money factor of 0.00100-0.00150 (2.4-3.6% APR) is good. In a higher rate environment 0.00200-0.00250 (4.8-6.0% APR) may be typical. Always compare the equivalent APR to current auto loan rates.
What happens if I go over mileage on a lease? +
Exceeding your lease mileage allowance results in per-mile charges at the end of the lease — typically $0.15-0.30 per mile over the limit. If you expect to drive more than the standard 10,000-12,000 miles per year negotiate a higher mileage allowance upfront. Pre-purchasing extra miles at lease signing is usually cheaper than paying overage fees at turn-in.
Can I negotiate a car lease? +
Yes — the sale price (cap cost) is always negotiable and has the biggest impact on your payment. The money factor may also be negotiable with good credit. The residual value is typically set by the manufacturer and not negotiable. Focus on negotiating the lowest possible sale price first — every $1,000 reduction saves approximately $28 per month on a 36-month lease.
