Prepaid Mileage on a Lease: Do the Upfront Miles Actually Save Money?

By Sarah Mitchell2026-03-035 min read

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

Watch out

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.

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>.

Frequently asked questions

Is prepaid mileage cheaper than the penalty?+
Almost always — typically 30–40% less per mile. The risk is losing unused miles, so only prepay when you are confident you will drive them.
Can I get a refund for unused miles?+
Generally no. Prepaid miles are not refundable. A few leases allow applying them to a new lease with the same brand, but do not count on it.
Can I buy miles mid-lease?+
Some lessors let you add miles during the term, usually priced between the prepaid and penalty rates. It is cheaper than waiting for turn-in but not as cheap as at signing.
Should I just buy the car instead?+
If you are far over and the residual is at or below market, yes — buying cancels the mileage bill entirely. Otherwise prepay if you are moderately over.
