About this tool

Compare buying and leasing a car on final net worth rather than monthly payment: the model handles depreciation, financing, insurance, the federal EV credit, and for business owners the Section 179 deduction, then finds the break-even year where buying overtakes leasing.

A car is a depreciating asset, so the real cost of either path is depreciation plus financing plus running costs. Leasing packages that cost into a payment and hands the car back; buying pays it up front and keeps the residual. Which wins depends mostly on how long you keep cars and how you use taxes.

Frequently asked questions
Is leasing ever cheaper than buying?

It can be for short ownership periods, for business use with deductible payments, or when manufacturer lease subsidies are rich. Held past the break-even year the tool computes, buying nearly always wins.

What is the Section 179 deduction?

A US tax provision letting business owners deduct qualifying vehicle costs up front rather than depreciating them over years. Heavier vehicles have historically enjoyed the most generous limits, hence the famous SUV loophole.

How does the federal EV credit work?

Qualifying electric vehicles can earn a federal tax credit of up to $7,500, subject to price caps, income limits and sourcing rules that change over time. On leases the credit typically flows to the leasing company, which may pass it into the payment.
