Prepaid Mileage on a Lease: Do the Upfront Miles Actually Save Money?
Prepaying mileage is cheaper than the end-of-lease penalty — usually 30–40% less per mile. The catch is that unused miles are not refunded, so you must be confident you will drive them.

Key takeaways
- Prepaid miles typically cost 30–40% less per mile than the turn-in penalty.
- Unused prepaid miles are almost never refunded.
- Prepay only if you are confident you will exceed the base allowance.
- Compare against simply buying the car, which cancels mileage charges.
The per-mile price gap
If your contract charges $0.25/mile at return, prepaid miles at signing often run $0.15–$0.18. On 6,000 extra miles that is roughly $900–$1,080 prepaid versus $1,500 at return — a real saving. The lessor sells the miles cheap upfront because it locks in revenue.
The refund trap
Prepaid miles are a use-it-or-lose-it purchase. Drive 2,000 of the 6,000 you bought and the other 4,000 are gone — no credit, no refund. Only prepay if your mileage is predictable and clearly over the base allowance.
A simple decision table
| Your situation | Move |
|---|---|
| Sure to exceed by 5k+ | Prepay |
| Might exceed by 1k–2k | Pay at return (small bill) |
| Uncertain | Do not prepay; buy car if far over |
| Way over (10k+) | Consider buyout to cancel |
How to estimate honestly
Take last year's odometer delta and add known changes (new commute, a move). If you landed at 14,000 miles on a 12,000 allowance, prepaying 3,000–5,000 extra miles is a safe bet. If you were at 11,000, skip it. The excess-mileage calculator at <a href="/calculators/lease-excess-mileage/">our tool</a> shows the break-even.
The buyout escape
If you are wildly over and the residual is near market, buying the car cancels every mile charge — often cheaper than prepaying thousands of miles you have not driven yet. That option is detailed in <a href="/guides/lease-buyout-worth-it-at-end-of-term">the buyout guide</a>.

A lower annual mileage allowance lifts the residual value, which drops your payment. The trap is that if you guess wrong, the per-mile overage erases the savings many times over.
