At lease end, you can generally return the car or exercise the purchase option in your contract. A car lease buyout calculator adds the residual and purchase option fee, an estimated sales-tax amount, and any title or registration charges you enter, then compares that total with the car's market value. Tax treatment and fees depend on the contract and jurisdiction.
A lease buyout is the exercise of a contractual purchase option at the end of a closed-end lease. The residual value is the lender's predetermined price for the vehicle, set when the lease began. The buyout cost is that residual plus the fees required to convert the lease into ownership.
How to Use the Car Lease Buyout Calculator
- Enter the residual: Type the "Residual Value" from your lease agreement. This is the buyout figure printed in the contract, not your own estimate of what the car is worth.
- Add fees and tax: Enter the "Purchase Option Fee" (varies by lender; some leases set it at $0, check your contract), any "Registration & Remaining Fees" still owed, and your local "Sales Tax" rate, which applies at buyout because tax was never paid during the lease.
- Choose financing: Use the "Finance the Buyout?" dropdown to pick between paying outright and financing it. If you finance, enter the "Buyout Loan APR" and pick a "Buyout Loan Term" of 24 to 60 months.
- Compare to market value: Enter the car's current market value so the tool can judge whether the buyout leaves you ahead or behind. Pull two figures rather than one — retail asking prices for the same year, model, and mileage, and a private-party or trade-in estimate — and check the buyout total against both, since a buyout behaves more like a private purchase than a dealership one.
- Calculate: Press Calculate to see the "Buyout Price To Pay", a breakdown of how that price is built, the monthly payment and interest added by financing if you chose to finance, and the buyout total against the market value.
The estimate applies only the tax rate, fees, and market value you enter, so confirm the actual residual, fees, and tax treatment on your contract before committing.
When a Lease Buyout Makes Sense
Identifying "Lease Equity": When Market Value Exceeds Contract Residual
Lease equity exists when the car is worth more than the price you must pay to own it. The simplest version compares market value with the residual. If the residual is $18,000 and the car is worth $20,000, there is $2,000 of gross equity before fees and tax.
The calculator uses a stricter version. It compares market value with the full cash buyout cost, including the purchase fee, sales tax, and registration charges. In the verified example, the $20,000 market value exceeds the $18,000 residual by $2,000, but the $19,914 cash buyout leaves only $86 of net advantage. Fees and tax can consume most of a headline equity gap — and the return path is not free either: a contract's disposition fee at turn-in, plus the tax on whatever replacement vehicle you buy, comes out of that same $86, which is why both paths have to be priced before the residual comparison decides anything.
Checking the Car You Have Been Driving
Before exercising the option, run the inspection you would demand of a stranger's used car — with one advantage no listing can offer: you have already driven and inspected this exact vehicle for the full term.
- Service records: Confirm the maintenance schedule was followed and keep the documentation with the car.
- Accident history: Pull the vehicle history report; you know what happened, but the record matters at resale.
- Tires and brakes: Compare wear against the miles and months remaining in normal use, and price the replacement cost into the decision.
- Contract mileage and condition limits: Check where the odometer sits against the allowance, since excess-mileage charges apply only if you return the car.
A buyout may also avoid a lease-return disposition fee, depending on the contract, and it avoids shopping for a replacement in a market where used prices may have moved. Those advantages are real, but they are not free. Compare the buyout total with the cost of returning the car and buying an equivalent used vehicle, including any applicable return fees and the tax on the replacement.

The Locked Contract Residual Value (Set on Day One)
The residual is a prediction made when the lease was written. It is based on the lender's expected depreciation, the lease term, and the contracted mileage. It is not a live market price, which is why a car can be worth more or less than the residual at the end.
Use the residual printed on the lease agreement, not the dealer's asking price and not an online valuation. The calculator treats it as the base of the buyout. If you are buying out early rather than at lease end, ask the lender for a written payoff quote, because early payoff can include remaining base payments and may differ from the scheduled residual. Federal consumer leasing rules require the agreement to disclose the purchase-option price and the conditions attached to buying the vehicle, which is why those terms belong in the contract rather than in a verbal quote; the FTC's car-leasing guidance walks through what the agreement has to state.
Lender Purchase Option Fees
Some leases charge a purchase option fee when you exercise the buyout, while others set a different amount or no fee. Check the lease agreement and the lender's buyout packet for the exact figure.
This fee is part of the taxable buyout subtotal in the calculator. It is separate from a disposition fee, which is typically charged when you return the car rather than buy it. Do not add both to the same path.
State and County Vehicle Sales Taxes Applied to the Buyout Balance
Lease and buyout tax rules vary. In some states, tax is collected on lease payments; a later buyout may be treated as a separate taxable sale, while other jurisdictions use different rules or exemptions. The rate and taxable base can vary by state and sometimes by county, so confirm your specific treatment with the relevant tax or motor-vehicle agency.
The calculator applies the tax percentage to the residual plus purchase fee. It then adds registration and remaining fees after tax. Confirm the rule with your state motor vehicle agency, because some states tax the residual only, some tax the full purchase price, and some offer credits for tax already paid on monthly lease payments.
Title, Registration, and Lien Documentation Charges
Ownership requires paperwork. Budget for title transfer, registration, license plate or tag fees, and any lien recording charge if the buyout is financed. Dealers may also add a document processing fee. These amounts vary widely, so use a quote from your state agency or the lender's buyout packet rather than a guess.
The calculator's remaining fees field is the place for these items. It does not know your state's title or registration schedule, so the accuracy of the total depends on the figure you enter.
Financing Your Lease Buyout
Used Car Loan Interest Rates vs New Vehicle Financing
A buyout is a used-car purchase even though you are the original driver. A new lender may price it as a used-car loan based on the vehicle and your application; do not assume a new-car promotional rate applies.
Credit unions, banks, and online lenders may offer different terms. A shorter term usually carries a higher payment; a longer term can lower the payment while increasing total interest. The calculator applies a fixed rate for the full term and assumes the entire cash buyout total is financed. A lender may require some fees or taxes to be paid separately, and its actual offer may differ.
Monthly Installment Breakdown for 36, 48, and 60-Month Buyout Notes
Using the verified $19,914 total at 6% APR, the payment and total interest look like this:
| Term | Monthly payment | Total interest | Total paid |
|---|---|---|---|
| 36 months | $605.83 | $1,895.59 | $21,809.59 |
| 48 months | $467.69 | $2,534.63 | $22,448.63 |
| 60 months | $385.00 | $3,185.55 | $23,099.55 |
The 24-month option is also available at $882.61 per month with $1,268.40 of interest.
When financing flips the verdict
The financing table changes the equity conclusion, not just the timing. In the verified example, the cash buyout beats the $20,000 market value by $86.00. Finance that same $19,914.00 at 6% over 36 months and the total paid becomes $21,809.59 — $1,809.59 above the car's market value. The interest alone ($1,895.59) exceeds the entire cash advantage many times over. That is the general rule worth taking from this page: the equity you are deciding on is a cash figure, and the interest can exceed it, so a thin cash advantage should either be paid in cash or treated as no advantage at all.
Navigating Dealership Markups and Direct-Lender Buyouts
Why Dealerships Try to Charge $1,000+ "Dealer Processing Fees"
A dealer may handle the buyout paperwork and add a processing fee. Some fees are legitimate; others are marked up well beyond the work. A $1,000 or higher "dealer processing" or "certification" charge deserves a written explanation before you pay it.
Ask for an itemized breakdown. Compare it with the lender's packet and your state's title and registration fees. If the dealer is not the owner of the lease, it may be a middleman, and the lender may allow a direct deal.
How to Execute a Direct Buyout Through the Captive Finance Arm
The captive finance arm is the lender affiliated with the automaker, such as the financing division behind the brand. Contact it before the lease ends and ask for the buyout instructions, a written payoff quote, and the documents it requires.
The process usually involves sending the payoff amount, completing title and tax forms, and arranging registration. Some lenders allow direct buyouts; others require a dealer to process the transaction. Ask specifically whether a direct buyout is permitted, what the purchase option fee is, and whether you must use a dealer for inspection or paperwork. Get the answer in writing before you sign anything at the dealership.
If you are deciding whether to keep the car, compare the original lease with the Car Lease Calculator, weigh leasing again against buying with the Car Lease vs Buy Calculator, or price a used-car loan through the Auto Loan Calculator.
A leasehold buyout in property law is a different transaction from a car lease buyout, and this tool covers only the vehicle version. Early lease termination is out of scope as well: the price here starts at the residual, adds the purchase option fee and the sales tax treatment, and assumes you are completing the deal rather than walking away from the contract.
