This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for United States change on a published schedule; the effective date is shown on every rule-based tool.
How this is calculated
A lease pays for depreciation over the term and returns the car. A loan pays for the whole car and leaves you owning it. Comparing the two fairly means measuring what you spent minus what you still have at the end, over the same number of months. The residual assumption drives everything: if the car holds its value better than assumed, buying wins by more.
Worked examples
Each of these is asserted on every build. If a change to the engine ever moved one of these answers, the build would fail before the page could print it.

degenerate case
Open this exampleMethod and limits
What it assumes
- The comparison runs over the lease term, with the loan balance at that point treated as still owed.
- Insurance, maintenance and fuel are similar either way and are excluded.
What it deliberately does not model
- Mileage penalties, wear charges and early termination fees are real lease costs and are not modelled.
- Business tax treatment differs sharply between the two and is not applied.

Frequently asked questions
- Why is the lease payment so much lower?
- Because you are only paying for the value the car loses during the term, not for the car. At the end you have nothing, which is the part a monthly comparison hides.
