This auto lease calculator works out the monthly payment on a lease quote from any brand and shows what sits inside it: depreciation, rent charge and sales tax. It also adds what you pay at signing, the mileage overage you can expect and the total cost of the lease.
Below the tool, every input and result is explained, along with the payment bar, the verdict and a worked example you can check by hand.

Where each payment goes
Estimates only. The starting values are made-up examples, not an offer from any lessor. Tax is applied to each payment, the most common state method; some states also tax cash down or tax the whole price up front. The first payment is counted as due at signing. Your lease contract shows the real figures.
What Is an Auto Lease Calculator?
An auto lease calculator turns the handful of numbers on a lease quote into the payment you will actually be billed. A lease is a long-term rental: you pay for the value the car loses while you drive it, plus a finance charge for the money the lessor has tied up in it. The calculator applies the standard closed-end lease formula used by US lessors, so you can check a dealer’s figure, test a different down payment or term, and see the full cost before you sign.
This version works for any make and model. Enter the MSRP, the price you negotiated, the residual and the rate from your quote, and it does the rest.
Why Run the Numbers Before You Lease
Lease ads are built around one number, the monthly payment. That payment can be lowered in ways that do not make the lease cheaper: more money down, a longer term, fewer miles. Seeing the payment split into its parts shows whether you are getting a good price, a fair rate and a mileage plan that fits how you drive.
- Check the quote. If your math and the dealer’s payment differ by more than a few dollars, something has been added or changed. Ask what it is.
- Negotiate the right item. A lower selling price cuts the depreciation part directly. A lower money factor cuts the rent charge.
- Avoid surprises at turn-in. Mileage overage is billed when you return the car, long after the payment was agreed.
Inputs Used in the Calculator
MSRP
The manufacturer’s suggested retail price, including destination. It matters because the residual value is set as a percentage of MSRP, not of the price you pay.
Negotiated Selling Price
The price you agreed with the dealer before any money down. It becomes the capitalized cost. A discount here lowers the cap cost but not the residual, so every dollar off comes straight out of the depreciation you pay for.
Lease Term
Choose 24, 36, 39 or 48 months. The residual percentage changes with the term, so use the residual quoted for the term you pick.
Residual Value
The lessor’s estimate of what the car will be worth at lease end, written as a percentage of MSRP. It is also usually your purchase price if you decide to buy the car later. A higher residual means less depreciation to pay for.
Lease Rate: APR or Money Factor
Lessors quote the finance rate as a money factor, a small decimal such as 0.00250. Some dealers quote an APR instead. Pick the form your quote uses. Switching the setting converts the number for you, because money factor × 2,400 = APR. A money factor of 0.00250 is the same as 6% APR.
Cash Down and Trade-In Equity
Both reduce the capitalized cost. Trade-in equity is the trade’s value minus any loan still owed on it. If you owe more than the trade is worth, enter zero here and ask the dealer how the shortfall is handled, since it is often added to the cap cost.
Fees Paid at Signing
The acquisition fee, doc fee, title and registration. They are paid up front in this calculator, so they raise the amount due at signing and the total, but not the payment.
Sales Tax, Mileage Plan and Overage Rate
Enter your combined state and local rate. The tool taxes each payment, which is the most common state method. Then pick the yearly mileage allowance, enter the miles you really drive and the per-mile charge printed in the lease.
How the Calculator Works
Every closed-end lease payment is built from two parts, with tax added on top in most states.
- Adjusted cap cost = selling price − cash down − trade-in equity.
- Residual value = MSRP × residual percent.
- Depreciation fee = (adjusted cap cost − residual) ÷ months.
- Rent charge = (adjusted cap cost + residual) × money factor.
- Monthly payment = (depreciation + rent charge) × (1 + tax rate).
The rent charge adds the cap cost and residual together because, over the lease, the lessor has roughly the midpoint of those two values tied up in your car. Multiplying the sum by the money factor charges interest on that average. That is why the conversion factor is 2,400: it already contains the divide-by-two and the step from a yearly percent to a monthly decimal.
Due at signing is the first payment plus cash down plus signing fees. Total lease cost is every payment plus cash down, trade-in equity, signing fees and the expected mileage overage.
Understanding Your Lease Results
Estimated Monthly Payment
The headline is the payment including tax. The line under it repeats the number of payments and the cash due when you sign.
Depreciation Fee and Rent Charge
These are the two parts of the payment before tax. Depreciation is the car’s lost value spread over the term. The rent charge is the finance cost. If the depreciation looks high, the selling price is high or the residual is low.
Due at Signing and Total Lease Cost
Due at signing is the cash you hand over on day one. The total is everything the lease costs you from start to finish, including the trade equity you gave up.
Effective Monthly Cost and Cost per Mile
Effective monthly cost divides the total by the number of months. It is the fairest way to compare a zero-down offer with one that asks for money up front, or a 24-month lease with a 39-month one. Cost per mile divides the total by the miles you will really drive during the term.
Mileage Overage and Rate Check
Overage is the miles above your allowance over the whole term, times the per-mile charge. The last card converts your rate: if you entered an APR it shows the money factor, and the other way round, so you can compare it with the figure on the contract.
The Payment Bar and the Verdict
The bar splits one payment into depreciation (red), rent charge (dark) and tax (gray). A long dark segment means the financing is a large part of what you pay, and the money factor deserves a second look.
The verdict box reads the same split. These bands are our own guide, not an industry rule:
- Lean lease: the rent charge is under 25% of the payment before tax.
- Balanced lease: the rent charge is 25% to 40%.
- Finance-heavy lease: the rent charge is 40% or more.
If your real miles are above the allowance, the box adds the expected overage. A second note appears when you put money down, as a reminder of the risk explained below.
How to Use the Lease Calculator Step by Step
- Ask the dealer for the MSRP, selling price, residual percent, money factor and fees in writing.
- Enter the MSRP and selling price.
- Pick the term and enter the residual for that term and mileage plan.
- Choose whether your quote shows an APR or a money factor, then enter it.
- Add cash down, trade-in equity and the fees due at signing.
- Enter your tax rate, mileage plan, real yearly miles and the overage charge.
- Press Calculate Lease and compare the payment with the quote.
Lease Example: A $42,000 Car Over 36 Months
The starting values are an example, not a real offer: a $42,000 MSRP car sold for $39,500, $2,000 down, a 58% residual, 6% APR (money factor 0.00250), 7% tax and $995 in signing fees.
| Step | Math | Result |
|---|---|---|
| Cap cost | $39,500 − $2,000 | $37,500 |
| Residual | $42,000 × 58% | $24,360 |
| Depreciation | $13,140 ÷ 36 | $365.00 |
| Rent charge | $61,860 × 0.0025 | $154.65 |
| Payment | $519.65 × 1.07 | $556.03 |
Due at signing is $556.03 + $2,000 + $995, or about $3,551. The plan allows 12,000 miles a year but the driver covers 13,000, so 3,000 extra miles at $0.25 add $750 at turn-in. The total lease cost comes to about $23,762, an effective $660.05 a month. The rent charge is 29.8% of the payment before tax, so the verdict is a balanced lease.
Who Should Use an Auto Lease Calculator
First-Time Lessees
If you have never leased, the calculator shows which numbers on a quote really drive the payment, so you know what to ask about.
Shoppers Comparing Brands
Because it is brand-neutral, you can enter quotes for different cars one after the other and compare effective monthly cost and cost per mile.
Drivers Deciding Between Lease and Loan
A lease costs less per month for a similar car, but you build no equity. Set the effective monthly cost against a loan payment minus the equity you would have at the same point. If you plan to keep a car for many years and drive a lot, buying usually costs less in the long run.
Common Lease Mistakes and Tips
- Comparing payments only. Judge offers by effective monthly cost, which counts money down, fees and overage.
- Mixing up MSRP and selling price. The residual uses MSRP. The discount comes off the selling price.
- Accepting a marked-up rate. Lessors publish a base money factor for each credit tier, and a dealer may add to it. Ask for the base rate.
- Underestimating miles. A low allowance makes the payment look small and the turn-in bill large. Buying extra miles up front is often cheaper than paying overage later.
- Putting a lot of cash down. If the car is totaled or stolen early, insurance and GAP coverage settle the lease, but the cash you put down is usually not returned.
- Forgetting the disposition fee. Many leases charge one when you return the car. It is often waived if you lease again with the same lessor.

Frequently Asked Questions
How is a lease payment calculated?
Take the adjusted cap cost minus the residual and divide by the months to get depreciation. Add the rent charge, which is the cap cost plus the residual times the money factor. Then add sales tax.
How do I convert a money factor to APR?
Multiply the money factor by 2,400. A money factor of 0.00250 equals 6% APR. To go the other way, divide the APR by 2,400.
What is a good residual value?
A higher residual means less depreciation to pay for, so the payment is lower. Residuals are set by the lessor for each model, term and mileage plan, so compare them between similar cars rather than against a fixed number.
Should I put money down on a lease?
Usually as little as possible. Money down lowers the payment but barely changes the total cost, and it is typically lost if the car is totaled or stolen early in the lease.
Is the first payment due at signing?
In most leases, yes. This calculator counts the first payment as part of the amount due at signing.
Why does a longer lease have a lower payment?
The depreciation is spread over more months and the residual is usually lower, so the payment drops a little. You also pay rent charges for longer and may face more repairs and tire costs near the end.
How do states tax a lease?
Most states tax each monthly payment. Some also tax cash down, and a few tax the full price or the total of payments up front. Check with your state revenue department.
What happens if I drive more than my allowance?
You pay the per-mile charge in the lease for every mile over the total allowance when you return the car. If you buy the car at lease end, the overage usually does not apply.
