Lease Break Even Calculator

The crossover point

Leasing and buying have different cost shapes. Leasing is close to linear: roughly the same amount every month, forever. Buying is front-loaded through depreciation and financing, then drops sharply once the asset is paid off and you are only covering maintenance. Somewhere the cumulative lines cross, and after that point buying is cheaper for every additional month you keep the asset.

What moves the crossover

Resale value matters most. An asset holding its value well shortens the payback on buying considerably, because depreciation is the real cost of ownership. Financing rate matters next: cheap credit brings the crossover forward, expensive credit pushes it back. Usage matters in both directions, since heavy use accelerates depreciation but also triggers lease excess charges, which are typically punitive.

Excess mileage and wear

These are where lease comparisons quietly fail. Per-mile excess charges are set well above the marginal depreciation they represent, and return inspections assess wear against a standard that is stricter than most people expect. A lease that looked competitive can end with a four-figure settlement. If your usage is uncertain, that uncertainty is itself an argument for buying, because ownership has no cliff-edge penalty for using the asset more.

Include maintenance honestly

A lease usually covers the asset during its most reliable years and hands it back before major maintenance falls due. Ownership past the warranty period carries real and lumpy costs. Comparing a three-year lease against ten years of ownership without budgeting maintenance in years four to ten flatters buying substantially.

The answer is usually about horizon certainty

If you know you will keep the asset well past the crossover, buying wins clearly. If you genuinely do not know, the flexibility of leasing has value that the arithmetic does not capture. Being honest about which situation you are in matters more than the precision of the calculation.
