Car Lease Calculator
Car lease calculator: your monthly lease payment from MSRP, price, residual and money factor, with lease vs buy check. Free, no sign-up, and it runs in your browser.
Dedicated page: /en/car-lease-calculator
Estimate only, not financial advice. Lease numbers come from the dealer worksheet: ask for the money factor, residual and adjusted cap cost in writing before you sign.
Example default 0.0020, about 4.8% APR. Enter the money factor from your lease worksheet.
Trade value minus what you still owe on it. Enter 0 if none.
Most states tax each monthly payment. A few tax the full price up front: check your state.
If the car is worth more than the residual, buying it out can pay. If it is worth less, hand it back.
Quick answer
A car lease calculator works out your monthly lease payment from the MSRP, the negotiated price, the residual value and the money factor. It splits the payment into depreciation, rent charge and tax, shows what is due at signing and the total lease cost, prices excess miles, and compares leasing with buying the same car on a loan.

What is a car lease calculator?
A car lease calculator turns a dealer lease worksheet into a monthly payment you can check. A lease payment is not like a loan payment: it has two parts, not one. Sales tax goes on top. This tool shows all three parts separately, so you can see whether a quote is expensive because the car loses value fast, because the money factor is high, or because the tax is heavy.
How a lease payment is worked out
First comes the residual value: the MSRP times the residual percent. A $38,000 car at 57% is worth $21,660 at lease end. Then comes the adjusted cap cost: the negotiated price plus the acquisition fee, minus the down payment, trade-in equity and rebates. Depreciation is the cap cost minus the residual, divided by the months. The rent charge is the cap cost plus the residual, times the money factor. Add them, add tax, and that is the monthly payment.
Why the residual is the biggest lever
The residual is set by the leasing company for that exact car, term and mileage allowance, and it rides on the MSRP, not the price you negotiate. That distinction matters: knocking $3,000 off the price lowers the depreciation you finance while leaving the residual untouched, so every bit of discount flows into a lower payment. A higher residual also lowers the payment directly, because there is less value to pay for. That is why some cars lease far more cheaply than others at the same sticker price: models with a strong reputation for holding value earn high residuals, so you finance less depreciation.
Lease vs buy
Leasing rents the fastest-depreciating years of a car. The payment is lower because you only pay for the slice of the car life you consume, not the whole car. Buying costs more a month but ends with an asset: after three years you own a car worth the residual value. On the example, buying is $3,220.36 cheaper over three years after the resale value, while leasing wins on the monthly payment and a new car every few years.
Best practices
- Negotiate the price first, then the lease: the residual rides on MSRP, so every dollar off the price lowers the payment.
- Match the mileage allowance to how much you really drive, and pre-buy miles if you know you will exceed it.
Common mistakes
- Judging a lease by the monthly payment alone, without the due-at-signing cash and the total cost.
- Comparing a money factor with a loan APR without converting it: 0.0020 looks tiny and is really about 4.8%.
- Forgetting the disposition fee, excess mileage and wear charges at return.

Worked example
A $38,000 MSRP car negotiated to $35,000, with a 57% residual ($21,660), a 0.0020 money factor (about 4.8% APR), 36 months, $2,000 down, a $695 acquisition fee and 7% tax: the adjusted cap cost is $33,695, depreciation is $334.31 a month, the rent charge is $110.71 a month, and the monthly payment is $476.17. Due at signing is $2,876.17 and the total lease cost is $19,892.00. Buying the same car on a 6% loan costs $1,064.77 a month, $38,331.64 in all, but you keep a car worth $21,660, so buying is $3,220.36 cheaper over three years.
Frequently asked questions
What is a money factor?
The lease version of an interest rate, quoted as a small decimal like 0.0020. Multiply it by 2,400 to read it as an APR: 0.0020 is about 4.8%. It is charged on the cap cost plus the residual, not on a falling balance like a loan.
What is the residual value?
The share of the MSRP the leasing company expects the car to be worth at lease end. A $38,000 car at 57% has a $21,660 residual, which is also your buyout price. A higher residual means less depreciation to pay for, so a lower monthly payment.
What is due at signing?
The cash you pay when you drive away: usually the down payment, registration and document fees, and the first monthly payment. On the example it is $2,876.17. A security deposit is added if the lessor requires one.
Should I put money down on a lease?
Usually no, or as little as possible. A $2,000 down payment cuts the monthly figure but barely cuts the total cost, and the cash is gone if the car is totaled early. Keep the down payment small and the monthly payment honest.
How much do extra miles cost?
Your allowance times the lease years, at the per-mile charge in your contract, usually $0.15 to $0.30 a mile. Driving 15,000 miles a year on a 12,000-mile lease for 3 years is 9,000 miles over, or $2,250 at $0.25 a mile. Pre-buying miles is usually cheaper.
Is leasing cheaper than buying?
The monthly payment is lower, because you only pay for the value you use up. Over the same years, buying is usually cheaper in total, because you keep the resale value. Leasing wins when you want a new car every few years and a predictable payment.
What happens at the end of a lease?
You return the car and pay the disposition fee plus any excess mileage and wear charges, or you buy it for the residual plus any purchase-option fee. If the car is worth more than the residual, buying it out and selling it can pay.
