Auto Lease Calculator
Auto Lease Calculator
Enter the vehicle price (capitalized cost), any down payment or cap cost reduction, the residual value as a percentage of the vehicle price, the lease term, and either a money factor or an APR. We calculate your monthly depreciation charge, finance charge, and total lease payment.
Money factor × 2400 ≈ equivalent APR, so money factor = APR ÷ 2400. Switch modes above to enter whichever number your lease quote gave you.
What Is a Car Lease?
A car lease is essentially a long-term rental. Instead of financing the entire purchase price of a vehicle, you're only paying for the portion of its value you expect to use up during the lease term — the difference between what it's worth today and what it's projected to be worth when you hand it back. In exchange, you get a lower monthly payment than a comparable loan, but you never build equity, you're capped by an annual mileage allowance, and you don't own the car at the end unless you separately buy it out.
The math behind a lease payment looks nothing like a standard loan amortization schedule, which is why lease quotes can feel opaque compared to financing. Three numbers do almost all the work: the capitalized cost (the negotiated price), the residual value (the leasing company's estimate of the car's future worth), and the money factor (the lease's interest rate, expressed as a small decimal instead of a percentage). This calculator takes those three inputs — plus any down payment or cap cost reduction and the lease term — and shows you exactly how your monthly payment breaks down.
If you're weighing a lease against financing the same vehicle, our car loan calculator uses the same vehicle price to model the ownership side of that decision, so you can compare the two side by side rather than guessing.
How to Use This Calculator
Enter five numbers, plus your choice of rate format, and the calculator does the rest.
Vehicle Price (Capitalized Cost) and Cap Cost Reduction
Vehicle Price is the negotiated capitalized cost of the car — the lease equivalent of the purchase price. Down Payment / Cap Cost Reduction is any amount that lowers that starting number before the lease begins, whether it's cash, trade-in equity, or a manufacturer rebate. Subtracting the reduction from the price gives you the adjusted capitalized cost, which is what the rest of the calculation is based on.
Residual Value
Enter the residual value as a percentage of the vehicle price — this number comes from your lease quote or the leasing company's residual value guide, not from you. It represents what the car is projected to be worth at lease-end and is calculated against the full vehicle price, independent of any down payment you make.
Money Factor or APR
Use the toggle above the calculator to switch between entering a money factor (the small decimal format used on most lease worksheets, e.g. 0.002) or an APR (a more familiar percentage, e.g. 4.8%). Enter whichever number your lease quote actually gave you — the calculator converts between them using the standard money factor × 2,400 ≈ APR relationship.
Lease Term
Enter the lease length in months — most leases run 24, 36, or 39 months. Shorter leases generally track new-vehicle value more closely, while longer leases can lower your monthly payment but expose you to more wear-and-tear risk before you hand the car back.
The Formula Explained
The calculator works in three stages, using the same logic a leasing worksheet uses behind the scenes:
Adjusted Capitalized Cost = Vehicle Price − Cap Cost Reduction
Residual Value = Vehicle Price × Residual Percentage
Monthly Depreciation = (Adjusted Capitalized Cost − Residual Value) ÷ Lease Term
Monthly Finance Charge = (Adjusted Capitalized Cost + Residual Value) × Money Factor
Total Monthly Payment = Monthly Depreciation + Monthly Finance Charge
Notice that the finance charge is based on the sum of the adjusted cap cost and residual value, not just the declining balance the way loan interest is. This reflects that a leasing company has capital tied up in the full value of the car (which it will eventually recover, either from you or from selling the car at lease-end) for the entire term, not just the depreciating portion.
Worked through with the calculator's own default numbers: a $32,000 vehicle, a $2,000 down payment / cap cost reduction, a 55% residual value, a 36-month term, and a 4.8% APR (equivalent to a money factor of 4.8 ÷ 2,400 = 0.002). The adjusted capitalized cost is $32,000 − $2,000 = $30,000. The residual value is $32,000 × 55% = $17,600. Monthly depreciation is ($30,000 − $17,600) ÷ 36 ≈ $344.44. The monthly finance charge is ($30,000 + $17,600) × 0.002 = $95.20. Adding them gives a total monthly payment of approximately $439.64.
Real-World Examples
Example 1: A $32,000 Vehicle at 4.8% APR
Using the figures above — $32,000 price, $2,000 down, 55% residual, 36-month term, 4.8% APR — the calculator returns a residual value of $17,600, monthly depreciation of about $344.44, a monthly finance charge of about $95.20, and a total monthly payment of approximately $439.64, with an equivalent APR that matches the 4.8% you entered.
Example 2: A Higher-Residual Vehicle With No Down Payment
Suppose you're leasing a $40,000 vehicle known for strong resale value, with no cap cost reduction, a 60% residual, a 39-month term, and a money factor of 0.00125 (equivalent to a 3.0% APR). The adjusted capitalized cost stays at $40,000, and the residual value is $40,000 × 60% = $24,000. Monthly depreciation is ($40,000 − $24,000) ÷ 39 ≈ $410.26. The monthly finance charge is ($40,000 + $24,000) × 0.00125 = $80.00. The total monthly payment comes out to approximately $490.26 — notice that even on a $8,000-more-expensive vehicle, the higher residual value and lower money factor keep the payment only modestly above Example 1.
Example 3: Lease vs. Buy on the Same Car
Take the Example 1 vehicle — $32,000 price, $2,000 down — and instead finance the $30,000 remaining balance as a loan at the same 4.8% APR over the same 36 months (ignoring sales tax for a like-for-like comparison; use our car loan calculator for a real quote including tax and trade-in). A $30,000 loan at 4.8% over 36 months carries a monthly payment of approximately $896.45— more than double the lease payment of $439.64. The reason is straightforward: the lease payment only covers the car's projected $12,400 of depreciation (plus a finance charge) over those 36 months, while the loan payment repays the entire $30,000 principal plus interest over the same period. The lease is cheaper monthly because you're returning the car with $17,600 of remaining value still attached to it; the loan is more expensive monthly because at the end you own that $17,600-plus of value outright.
Tips and Limitations
A Lower Payment Isn't Automatically a Better Deal
Comparing a lease payment to a loan payment on its own is misleading, since a lease never builds equity. If you plan to keep vehicles for many years past when a loan would be paid off, buying is usually cheaper in the long run even though the monthly payment is higher while you're paying down the loan.
Watch Your Mileage Allowance
Most leases include 10,000–15,000 miles per year, with a per-mile charge (often $0.15–$0.30) for anything over that at lease-end. If you drive significantly more than the included allowance, either buy more miles upfront (usually cheaper per mile than paying the overage penalty) or reconsider whether leasing fits your driving habits at all.
Shop the Money Factor Like You'd Shop an Interest Rate
Dealers can and do mark up the money factor above what the leasing bank actually approved, the same way they can mark up a loan's interest rate. Ask for the "buy rate" money factor, and if you have strong credit, don't assume the first number you're quoted is the best one available.
This Calculator Doesn't Include Tax, Acquisition, or Disposition Fees
Real lease quotes typically add a monthly use tax (rules vary widely by state), a one-time acquisition fee charged at signing, and a disposition fee charged when you return the vehicle. This calculator isolates the depreciation and finance charge math so you can see it clearly — add your state's and lender's specific fees on top of the total shown here for a complete out-the-door comparison.
Frequently Asked Questions
What is a money factor and how do I convert it to APR?
A money factor is the way leasing companies express the interest rate on a lease, usually written as a small decimal like 0.00200 rather than a percentage. To convert it to an approximate APR, multiply by 2,400 — so a money factor of 0.002 is roughly equivalent to a 4.8% APR. To go the other direction, divide the APR by 2,400. This calculator lets you enter either one directly; whichever number your lease quote gives you, use the matching toggle above and it will compute the other for you automatically.
What is residual value and who decides it?
Residual value is the leasing company's estimate of what the vehicle will be worth at the end of the lease term, expressed as a percentage of the vehicle's original price. It is set by the leasing bank (often based on data from ALG or a similar residual-value guide), not negotiated by you, and it is the single biggest driver of your payment: a higher residual value means less projected depreciation, which means a lower monthly payment. Vehicles known for holding their value well — many trucks and certain SUVs — tend to have higher residuals and therefore cheaper leases relative to their price.
What is capitalized cost and cap cost reduction?
Capitalized cost (or "cap cost") is leasing terminology for the vehicle's negotiated price — the lease equivalent of the purchase price in a loan. Cap cost reduction is any amount that lowers that starting number before the lease begins: a cash down payment, trade-in equity, or a manufacturer rebate all work as cap cost reduction. The result after subtracting it is your adjusted (or net) capitalized cost, and it's this smaller number — not the sticker price — that your depreciation and finance charge are actually calculated from.
How is my monthly lease payment split into depreciation and finance charge?
Every lease payment has two parts. The depreciation portion covers the value the car is expected to lose over the lease — calculated as (adjusted capitalized cost minus residual value) divided by the number of months — and it's yours to pay because you're using up that value. The finance charge is effectively the interest on the lease, calculated as (adjusted capitalized cost plus residual value) multiplied by the money factor. Add the two together and you get your total monthly payment, which this calculator breaks out separately so you can see exactly what's driving your number.
Should I lease or buy a car?
Leasing typically means a lower monthly payment because you're only financing the vehicle's expected depreciation, not its full price — but you never build equity, you're bound by mileage limits, and you make payments indefinitely if you keep leasing new cars. Buying (see our car loan calculator) means a higher payment because you're financing the entire purchase price, but once the loan is paid off you own an asset outright with no more payments. If you drive a lot of miles, want to modify your car, or want to eventually own it free and clear, buying usually wins financially over the long run; if you prefer a lower payment, like driving a new car every few years, and don't mind never owning it, leasing can make sense.
What happens at the end of a car lease?
You generally have three choices: return the vehicle and walk away (subject to any excess mileage or excess wear charges), buy the vehicle outright for its residual value (the same number used to calculate your payments), or lease or buy a different vehicle. Buying out your lease can be a good deal if the car's actual market value at lease-end turns out higher than the residual value your lease locked in years earlier — it's worth checking a used-car valuation before deciding.
Can I negotiate the money factor or residual value?
The residual value is set by the leasing company's formula and is not negotiable. The money factor, however, often has room to move, especially if you have strong credit — dealers sometimes mark up the money factor above what the leasing bank actually approved, similar to a dealer markup on a loan's interest rate. It's worth asking the dealer for the "buy rate" money factor and comparing it to what you're quoted, the same way you'd shop an auto loan rate.
Does this calculator include sales tax or other lease fees?
No — it calculates the core depreciation and finance charge components of your payment from the capitalized cost, residual value, term, and money factor or APR, since those are the numbers that vary deal-to-deal and directly change what you're financing. Real-world leases often add a monthly use tax (state rules vary — some tax the full payment monthly, others tax it upfront), plus a one-time acquisition fee and an end-of-lease disposition fee. Check your state's rule and your lease quote for these additions, since they sit on top of the payment this calculator produces.
