Auto Lease Buyout Calculator: Is It Worth It?

A lease buyout price is not simply the residual value printed on your lease contract. It's the residual value plus a purchase-option fee and, in most states, sales tax on that amount — and if you're buying out early, the math gets more complex still.

This guide breaks down where the number comes from and how to decide whether buying out beats turning the car in.

What a lease buyout actually costs

Your total buyout cost is the residual value stated in your lease, plus a purchase-option fee (commonly $300 to $500), plus sales tax on that amount in most states, according to the CFPB's guidance on leasing versus buying.

Say your residual value is $21,000, your purchase-option fee is $350, and your state charges 6% sales tax on the residual. Sales tax adds $21,000 × 0.06 = $1,260. Your total buyout cost is $21,000 + $350 + $1,260 = $22,610.

How the residual value was set in the first place

The residual value was calculated when you signed the lease, as a projected percentage of the car's value at lease-end. Your monthly lease payment itself is built from two pieces: depreciation (the drop from cap cost to residual, spread over the term) and a finance charge based on the money factor, the lease equivalent of an interest rate.

On a car with a $35,000 capitalized cost, a $21,000 residual (60%), a 0.00125 money factor, and a 36-month term: depreciation is ($35,000 − $21,000) ÷ 36 = $388.89 a month, and the finance charge is ($35,000 + $21,000) × 0.00125 = $70.00 a month. Total payment (before tax): $458.89. The residual value you'll pay to buy out the car is the same $21,000 baked into that payment from day one.

Early buyout vs. end-of-lease buyout

Buying out before your lease term ends usually costs more than waiting, because an early payoff includes the present value of your remaining scheduled payments on top of the residual — not just the residual alone. Most leases don't print this early-payoff number in the contract; you have to call your leasing company for the exact figure.

If you're near the natural end of your lease term, waiting for the standard end-of-lease buyout is almost always cheaper than paying out early, unless you're facing steep mileage-overage or wear-and-tear charges that a buyout would avoid entirely.

Buyout vs. financing a comparable used car vs. leasing again

| | Buy out your lease | Finance a used car | Lease again | |---|---|---| | You already know the car's condition | Yes | No — unknown history | Yes (new car) | | Avoids mileage/wear-and-tear fees | Yes | N/A | No — new limits apply | | Upfront cost | Residual + fee + tax | Down payment + fees | Often lowest | | Long-term ownership | Yes, once paid off | Yes, once paid off | No — return again |

Buying out makes the most sense when you know the car's full maintenance history, it's held up well, and the buyout cost compares favorably to a similar used car with unknown history.

Common mistakes to avoid

Skipping a pre-purchase inspection because you've been driving the car — mechanical issues don't always show up in daily driving the way they do under a lift.

Financing the buyout through the leasing company's rate without shopping it against a bank or credit union loan first; buyout loan rates are not always competitive.

Missing your lease's purchase-option window. Some leases only allow the buyout at specific points (like the final 60–90 days), not any time you choose.

Frequently asked questions

What is a lease buyout?

A lease buyout is purchasing your leased vehicle at the end of (or during) the lease term, instead of returning it. The price is the residual value from your contract plus a purchase-option fee and, in most states, sales tax on that amount.

How is the residual value calculated?

The residual value is set at lease signing as a projected percentage of the car's value at lease-end, based on expected depreciation. It's baked into your monthly payment from day one — the difference between the capitalized cost and the residual, spread across the lease term.

Is buying out my lease better than financing a used car?

It depends on the numbers and what you know about the car. Buying out avoids the unknown maintenance history of a used car and any mileage-overage fees, but only makes sense if the total buyout cost compares favorably to a similar used car on the market.

Can I negotiate my lease buyout price?

The residual value itself is typically fixed by contract, but the purchase-option fee and any add-ons sometimes have room to negotiate. Getting your own financing quote before negotiating gives you a stronger position than accepting the leasing company's buyout loan rate by default.

Do I have to pay sales tax on a lease buyout?

In most states, yes — sales tax applies to the residual value at the time of purchase, similar to buying any used car. The exact rate depends on your state and sometimes your county, so check your local rate before budgeting your total buyout cost.
