Mileage break-even calculator
How many miles over is too many to hand the car back?
There is an exact number, and it is different for every lease. Past it, the overage charge alone costs more than buying the car outright — at which point paying to walk away from a vehicle you have already paid for stops making sense. Here is where your line sits.
Where the money goes
Why the threshold moves
It is not really about mileage. The break-even point is set by the gap between what the car is worth and what it costs to buy — mileage just decides how expensive the alternative is. Narrow that gap and the threshold falls; a car already worth more than its payoff is past the line before you drive a single extra mile.
Overage is the one charge that disappears entirely. You cannot be over-mileage on a car you own. Neither the disposition fee nor the wear assessment survives a purchase either — which is why a car that would fail a return inspection is often the one most worth keeping.
The comparison excludes what you drive next. Returning the car leaves you needing one. Read the return column as the cost of walking away, not as the cost of your next three years.
Not an approval, and not tax advice. Champion Auto Finance is not a lender; rates and terms are subject to lender underwriting, and your state sets the tax.
If you are past the line
Being over the threshold does not oblige you to buy the car — it means the cheaper of the two options is the one that keeps it. What normally decides the rest is whether you want this particular vehicle for another few years, and whether the payment works. You can run all four lease-end options side by side, including what financing the buyout would cost each month.
If you are under the line, the overage is real but it is not the whole picture either. Check the arithmetic behind the per-mile charge and confirm the figure against your own contract — allowances and rates vary, and the number people remember is often the one from a previous lease. Your lease-end statement spells out both.
One thing worth doing before either: get the payoff figure from the lender directly rather than from anyone who would like to buy the car, and check which company actually holds the lease. Policies on who may pay a lease off vary and change, so confirm yours rather than assuming.
