Lease Mileage Overage Calculator
Project lease mileage overage fees from annual driving pace, remaining lease months, and your contract mileage cap.
Lease mileage caps are easy to ignore until the odometer catches up. Enter how you drive now, months left on the lease, and your per-mile overage rate to see projected charges.
Projected overage
- Projected miles (remaining term)
- 22,500 mi
- Allowed miles (remaining term)
- 18,000 mi
- Projected overage miles
- 4,500 mi
- Projected overage cost
- $1,125
- Average monthly overage accrual
- $63
You are driving about 3,000 miles above your annual lease cap. Overage fees add up quickly near lease end.
Estimates based on your entered annual pace continuing unchanged. Actual lease contracts may use different mileage accounting, prepaid mileage bundles, or wear charges not included here. Confirm overage rate on your lease agreement.
How to use this calculator
Enter your current annual mileage pace — not your lease cap. If your driving increased after a job change, use recent months annualized.
Lease annual mileage cap is the yearly allowance in your contract, often 10,000, 12,000, or 15,000 miles.
Months remaining is time left until lease end. Overage fee per mile is on your lease agreement, commonly $0.15–$0.30.
What the results mean
Projected overage miles compare your pace against the allowance for the remaining term. Projected overage cost multiplies those miles by your entered fee.
Some lessors let you buy mileage packs before return at a lower rate. This tool does not model prepaid bundles.
Common questions
- Where do I find my overage rate?
- Check your lease contract or lessor account portal. The per-mile charge is usually listed in the mileage section. Dealer quotes at signing should match the contract.
- Can I reduce overage before lease end?
- Some manufacturers sell extra miles mid-lease at a discount versus end-of-lease charges. Carpooling, remote work, or swapping to a second household car can also slow odometer growth.
- Does this include wear and tear fees?
- No. This calculator models mileage overage only. Dents, tire wear, and interior damage are separate lease-end charges.
- Is this financial advice?
- No. Projections assume your current pace continues. Confirm terms with your lessor.
