The Car Lease Mileage Calculator helps determine potential overage charges when you exceed your leased vehicle's mileage allowance. It calculates the financial penalty based on your contract's per-mile rate.
The calculator uses the following formula:
Where:
Explanation: The calculation only applies to miles driven beyond your allowance. If you're under your allowance, the overage charge is $0.
Details: Knowing potential overage charges helps with lease-end planning and deciding whether to purchase additional miles upfront (often cheaper than paying overage fees later).
Tips: Enter your actual miles driven (or estimate), your contractual mileage allowance, and your lease's per-mile overage charge. All values must be non-negative numbers.
Q1: What's a typical mileage allowance?
A: Most leases offer 10,000-15,000 miles per year. A 3-year lease might have 30,000-45,000 total miles allowed.
Q2: What's the average per-mile charge?
A: Typically $0.15-$0.30 per mile, but can vary by leasing company and vehicle type.
Q3: Can I negotiate the overage charge?
A: Sometimes. It's often cheaper to purchase additional miles upfront if you anticipate going over.
Q4: How accurate does my mileage estimate need to be?
A: For planning purposes, estimate conservatively. For final calculations, use exact odometer reading.
Q5: Are there other lease-end charges?
A: Yes, may include wear-and-tear fees, disposition fee, and any outstanding payments or taxes.
